WELCOME

A month ago - on March 4, 2023 - the United Nations finalised its draft agreement referred to as the High Seas Treaty.

This Treaty covers all oceans that are outside the existing jurisdictions of any country. It’s being hailed as a landmark Treaty and one that will halt the decline in the loss of biodiversity and damage caused by human activities.

Roger Gilbert Publisher – International Aquafeed and Fish Farming Technology

The treaty recognises efforts already made by many who see that countering the decline in the health of the seas is critical to the human condition in the future. This agreement should guarantee the protection of our oceans for many decades to come.

This High Seas Treaty is now being adopted into national law by all UN member states.

But how is are the oceans to be protected and why won’t this document remain on Government bookshelves gathering dust over the decades ahead?? - To push protection beyond national boundaries and beyond the existing status quo that controls the ocean environment, the following programmes are being extended. They include Area Based Management Tools and Marine Protected Areas, which are already proving effective in protecting the ocean environment when its challenged by human activity and climate change in national waters.

In future these two programmes will be extended beyond national boundaries and come under the authority of the UN’s COP (its Conference of the Parties grouping) which will not be restricted by existing or independent organisations with special interests. There will also be powers for the COP to act where emergency action needs to be taken. The COP will also have the power to set up MPAs with wider influence, taking decisions where human activities are involved and correct any weaknesses and shortcomings in existing control measures may come to light from time-to-time.

The Treaty also overhauls antiquated and outdated environmental assessment policies and management practices and is set to put into place modern assessment and management requirements for activities that may impact marine biodiversity. Fish are to be considered as a primary component of marine biodiversity and will not be excluded under this Treaty.

Finally, another key part of the Treaty is its capacity building and the transfer of marine technology to small island countries and developing nations and where marine biodiversity is to be protected. These nations need to have the resources and skills to benefit from the implementation of the Treaty.

How is the Treaty to be managed?

In brief there is to be a new voting procedure within the Treaty to ensure that when consensus has not been reached, that one or two nations cannot hold decision-making hostage where the vast majority of countries are in agreement. Even the country-by-country ratification procedure of the Treaty has been taken into account so that its adoption cannot

be delayed, and its implementation is achieved in a timely manner.

Overall High Seas Treaty is a major step forward in bringing about an immediate and lasting protection of this worldwide and global resource - the oceans that bind us together. Congratulations to the United Nations and its member countries for creating such a meaningful document and may it be ratified by all member countries within the foreseeable future.

The Monaco Blue Initiative

It’s been an extraordinary period of time.

Within just a few weeks we will have celebrated the adoption by the United Nations of its High Seas Treaty (on March 4) World Flour Day (on March 20), World Water Day (on March 22) and World Earth Day (on April 22).

Let’s not overlook the 14th Monaco Blue Initiative meeting that took in Monaco on March 20th.

It was held in an atmosphere of celebration given the work the MBI has done over the four years and more to bring together groups, organisations and individuals associated with the ongoing protection and conservation of the oceans.

His Highness the Sovereign Prince Albert, told the meeting of the MBI which attracted some 185 delegates that, “Thanks to this agreement, we will at last have the legal tools available that will help us protect international waters more efficiently, by being able to establish marine protected areas in the High Seas, which I have long been calling for.”

We congratulate Prince Albert for his dedication and perseverance in galvanising those involved in conservation to consider ocean ecology to come together to discuss how nations and groups could contribute and achieve more by working together.

We report on this important annual event, which takes place in a country outside Monaco, every second year, in our pages this month.

And in closing please do not overlook the opportunity to check out any one of our language editions and their respective digital offerings by accessing our ’Useful Language Links’ here: http://flk.bz/xxsY

Have an enjoyable April. We look forward to reaching you with our wide range of topics related to the production and use of aquatic feeds in the next edition.

It has been a very busy year for me with regard to research on fish nutrition covering various topics.

My associations with former PhD students have enabled me to participate with them at locations such as their new university affiliations in the Middle East and also Kurdistan. One such student is Dr Abdelwahab Abdelwarith who has invited me into his programme of activities based in Saudi Arabia.

Saudi Arabia is undertaking excellent work in aquaculture covering many species of fish and also shrimp. There is a network forming with Egypt, India, Pakistan and together with my involvement we are implementing experimental investigations to push the frontiers of fish biochemistry, physiology and molecular biology to advance our knowledge of fish nutrition. We are linking this to its importance in enhancing immune function and disease resistance in farmed aquatic animals. These colleagues have bespoke facilities for undertaking pathogen challenge tests that are unique for purposes of validation of specific feed additives for health.

We have published some good papers this year in high quality peer-reviewed journals with work focusing on tilapia, seabass, seabream, snakehead and also shrimp. I hope to report in our magazine some aspects of this work for the wider audience in due course.

Making waves in the seafood domain is a young American student at Northeastern University in Boston, Massachusetts who is studying for his degree in Biological Sciences specialising in Cell and Genetics.

James Sibley, just 23 years old, has come to my attention from his excellent TikTok channel posts on all thing’s seafood and aquaculture. James is a natural broadcaster and orator showing an informative and balanced perspective of the industry but with strong elements of science.

He demonstrates very thorough knowledge of many disciplines within aquaculture but is keen to explain molecular and cell biology with respect to genomics including advances in CRISPR, genetic engineering and also fish nutrition. He is quite a scholar and well recognised for his achievements by his university making the Dean’s list and receiving other awards. James has been interviewed on many platforms including the Global Seafood Alliance and the Fish Site. I am in regular communication with him, and we hope to have him write some features for us here in IAF soon after he graduates this May.

Good luck to him for his degree!

VIV Asia

Last month, I travelled with our Perendale Publishers’ team to the VIV Asia meeting in Bangkok and gave the keynote address and also moderated our separate VIV Aquatic Asia Session. This was sponsored by several companies and VIV allowing several speakers to participate internationally. This was so well

attended, and the room was packed with over 100 attendees.

Of course, Thailand is a superb location for engagement with the rapid rise of aquaculture in Asia. As such, I was able to see many friends including some of my former PhD students now holding very good jobs relating to aquaculture. I wish to thank Shannon Parsons for all her help in the organisation and our Tuti Tan. Shannon is the new team member in our Cheltenham, UK HQ and contributes so much of her skills in her associate editorial capacity.

Controversial topic

Recent developments to catch my eye is the new tilapia nutrition and welfare course being promoted in Indonesia and this is of much importance to me given my academic and scientific standing. Tilapia must be given full consideration in this respect, and I am pleased to see progress in this direction as standards of tilapia rearing should be as high as salmon and other species. In a related area, organisations are pressuring the EU “not to use public funds to support octopus farming developments, or any other new industrial animal-based farming in the light of significant and growing scientific evidence that it is ‘harming our planet” as they might say.

The Spanish company Nueva Pescanova are currently rearing their fifth generation of octopus at their research centre in Galicia. This is a controversial topic due to the fact the octopus has a high plane of sentience displaying complex behaviour.

I have discussed this in a previous issue of IAF but it has been highlighted again by several lobbies and various animal rights and environmental groups. I take a rather detached view as we also eat pigs, chickens and ruminant animals that also have a high degree of sentience, intelligence and behavioural patterns.

The husbandry of octopus under farmed conditions is now being developed and of course we need to know more to satisfy their health and welfare conditions. We must show our collective good practice and science and try to educate the misinformed, emotive campaigners.

Aquaculture feeds a growing world population and we all endeavour to be responsible and practice sustainability in our industry. We can be proud of our concerns and compliance with high standards and ethics.

In this issue we have all our regular feature, articles and special topics as well as our news and advertising pages. The aquafeed area is truly dynamic and IAF is the premier platform to communicate your business and to outreach your product’s potential. In Bangkok, I was approached by a large number of companies wishing to engage further with our team. Please connect with us and see our online platforms and magazines. Our printed magazines are very popular in English, Spanish, Chinese and Norwegian and easy to subscribe.

Professor Simon Davies

Nutrition Editor, International Aquafeed

The feed industry has for long been looking for new sources of raw material, and new ideas are popping up all over. Krill, insectmeal, seaweed meal, tunicates-meal etc. And of course, waste products from the seafood processing industry. It seems that a good place to look is in the waste bin of various processing plants. The FAO estimated some years ago that as much as 30 million tonnes of the catch was wasted, most of it thrown away because of deterioration or improper handling. But so far, the focus has been on cut-offs, intestines and other waste from the fish processing industry. What about waste from crustaceans?

The seafood industry generates huge quantity of waste during processing of the crustaceans such as shrimps, crabs and lobsters. After processing of the crustaceans, exoskeleton, carapace and hull are thrown out as a waste product in large quantities by seafood plants. These wastes contain appreciable amount of protein and carotenoids making them suitable as an animal feed. Furthermore, this waste can be used to replace the high value protein sources such as fish meal and soybean meal in the aqua feed. Their easy availability in the coastal regions and their low cost would definitely help in reducing the feed cost in the aquaculture.

Years ago, I remember finding huge piles of lobster shells just outside of Nouadhibou in Mauritania. It was serving as the garbage dump for waste from the nearby seafood restaurant. None of this was used for any purpose at all at the time. Crab processing has made big strides in recent years. As a crab lover myself, I am well familiar with the problem of getting rid of the waste after a crab meal. In my family, we prefer to attack

the cooked crab (the brown crab or Cancer pagurus) whole and pick it apart during what has become a social ritual as much as a pleasant meal. This ritual nevertheless produces some inedible parts, like the shell, the bones, etc. What we usually do is throw it in the garbage bin before it starts to smell. But in industrial crab processing, the amount of waste in the form of shell is mounting, and it cannot be thrown away just anywhere. But could this waste be of some value for example as a raw material for fish feed? Apparently yes. A new company in Norway, Nutrishell AS, is now in the process of starting the commercial exploitation of crab shells from the crab processing industry. And not only from the local crab industry, which is somewhat seasonal. Nutrishell is now importing crab shells from various countries, and thus securing a fairly steady supply of raw material for the production throughout the year. The end product is a crab shell powder, or crab shell meal, which in turn may be used as a raw material in fish feed.

Skretting is the main customer of Nutrishell, and they use the crab shell meal as a additive in their cod feed. Apparently, it makes the feed more palatable, and it helps improve the quality of the skin of the fish.

The Norwegian government is backing this development with a research grant of nearly USD 1 million. The EU Commission is also involved in financing this kind of research, although not specifically focuses on crab shell meal, through its EU Mission programme.

A great deal of research on this subject has also been done in India, by various scientists and institutes. In the near future, more research will be undertaken, and perhaps before long, this resource will be more common as an ingredient in aquafeeds.

The Aquafeed Journal

Aquafeed Journal is a new online publication by Perendale Publishers Ltd, United Kingdom, with a distinguished track record of technical and trade magazines in the agricultural and aquaculture sectors. This new peer-reviewed scientific journal will serve academia and the commercial aquaculture industry with high-quality papers relating to aquafeed science and technology for different species of farmed fish and crustaceans. It is envisaged to address fundamental nutritional requirements for effective and optimal production and applications to advanced feed formulations. This will include essential amino acids, proteins and energy sources as well as key vitamins and minerals pertaining to fish and shrimp growth, feed efficiency and health. A major area will be studies that focus on feed ingredient assessment and in particular those that are sustainable alternatives to marine derived materials like fishmeal and fish oil. Therefore investigations directed towards plant and next generation proteins like insect meal, algae and microbial sources would be desirable areas. Novel oils and lipids that provide essential fatty acids would be of considerable importance. Studies on functional ingredients affecting the health and immune function of fish and shrimp are very topical and of much interest to the commercial aquafeed sector. We would welcome papers researching the role of prebiotics, probiotics and phytobiotics on gut health, mucosal immunity and their interaction and modulation of the intestinal microbiota. Please do not hesitate to contact us with your queries at journal@perendale.co.uk.

United Nations signs historic deal to protect the oceans

After two decades of discussion and negotiation, the 193 member states of the United Nations have finally agreed on a legal framework to protect the ocean.

According to The Guardian, the treaty will enable the creation of enormous marine protected areas (MPAs) in those parts of the ocean that are outside national boundaries. This will help reduce the loss of wildlife, reverse acidification and share out the genetic resources found in the world’s oceans.

Oceans are critical to the survival of all life on the planet. They produce half the oxygen we breathe and soak up vast quantities of carbon dioxide. In particular, the ‘high seas’ – those areas outside of national boundaries that comprise nearly two-thirds of the ocean’s area – are critical to the healthy functioning of the whole marine system and are vital for many species of whales, sharks, sea turtles and fish, as well as enabling billions of dollars annually in economic activity. But, until now, the high seas were governed by fragmented and poorly enforced rules that have allowed increasing acidification of the waters and turned a blind eye to exploitation such as over-fishing and the dumping of pollutants, including millions of tonnes of plastic waste. This treaty will end this situation by providing a global, legally binding agreement that will provide comprehensive ocean governance.

The treaty will ensure the viability of the ‘30×30’ pledge made at COP15 in Montreal last year as part of the Global

Seaweed biomaterials startup secures US $6 million

Loliware, a seaweed-based biomaterials startup, recently secured $6 million in pre-series A funding.

The most recent funding, announced in February, brings total investment in the startup to $15.4 million – making it the market’s best-funded seaweed materials tech company to date.

Loliware says that its seaweedderived resins "are fully compatible with existing manufacturing plastic extruding equipment, providing a unique, cost-effective way to replace single-use plastics at scale." The seaweed can be processed into Loliware’s materials at local facilities and made into a wide array of products which compost easily and enrich the soil.

Company officials said they will use the funds to focus on continued growth in the seaweed materials market, launch several new products and novel seaweed resins, and expand the company’s research and development capabilities.

Biodiversity Framework that aims to reverse biodiversity loss, restore ecosystems and protect indigenous rights by protecting a third of the planet for nature by 2030.

There are many details yet to be hashed out, but it is likely the MPAs will have restrictions, or even complete bans, on fishing in order to slow and reverse the losses of marine species caused by years of unregulated overfishing. The treaty also aims to protect ocean ecosystems against the negative effects of deep sea mining. According to the BBC, environmental groups have serious concerns about the impacts of mining which include noise pollution and disruption to food sources and breeding grounds. Countries have pledged to put more money into ocean conservation, and there has been agreement to a more equitable sharing of marine genetic resources, such as materials from plants and animals, which can have economic benefits when used as food or pharmaceuticals.

Reaching this point took years of negotiations, with countries wrangling over issues such as how to ensure a fair and equitable sharing of benefits between developed and developing countries, and what models to use for the environmental impact studies of planned activities in the protected areas.

But eventually all 193 member countries were happy with the wording of the treaty. “The ship has reached the shore,” said the emotional conference chair Rena Lee to the delight of delegates when final agreement was reached in New York on March 4.

This most recent round of funders includes investors L Catterton, CityRock Venture Partners, Alumni Ventures Group, Geekdom Fund, Ehukai Investments, 5 Pillars Capital, Kilara Capital founder and managing director Ben Krasnostein, Clay Rockefeller, Kiss the Ground co-founder Ryland Engelhart, Nutiva founder and former CEO John Roulac, Blue Bottle Coffee founder Bryan Meehan, and others. US-based plastics manufacturer Sinclair and Rush has committed capital as well.

“Climate change is a worldwide problem, and our pelletized seaweed resins are a step toward a solution,” says Loliware founder and CEO Sea F Briganti, in a press release,. “By reducing CO2 emissions and strengthening the ocean-based ‘blue economy,’ our seaweedderived products make it clear that regenerating the Earth is good business.”

Founded in 2016, Loliware is at the forefront of tech companies focusing on regenerative materials that support

a stronger ecosystem. “Demand for seaweed-based products promotes the creation of seaweed-farming operations in coastal communities worldwide,” Briganti added. “This not only creates jobs where they are needed most but these undersea forests filter and oxygenate oceans while capturing carbon.”

“What Loliware has created is revolutionary and is on the cusp of a paradigm shift in plastics,” says Alumni Ventures’ managing partner, Cainon Coates. “By removing adoption and scale barriers, plastic manufacturers can simply swap plastic pellets for their seaweed pellets. The impact and upside potential are massive.”

Alltech and Finnforel join forces for sustainable aquaculture feed production

Alltech, a global leader in agriculture and animal nutrition, and Finnish circular-economy company Finnforel are joining forces to acquire the Raisioaqua fish feed production facility from Finnish company Raisio. Raisioaqua manufactures environmentally friendly feed for aquaculture and specialises in functional feeding solutions that are suitable for northern conditions. The acquisition will complete Finnforel’s sustainable circular-economy fishfarming chain while also enhancing aquaculture producers’ access to Alltech’s nutritional technologies.

“Aquaculture continues to be one of the world’s fastestgrowing sources of protein, according to Alltech’s annual Agri-Food Outlook, and is one of the key focus areas for our business,” says Dr Mark Lyons, president and CEO of Alltech. “Together with Finnforel, we will be enhancing the quality and availability of nutrition for sustainable aquaculture systems. Aqua producers will benefit from the strength of Alltech’s scientific research and commercial expertise globally, including a dedicated aqua nutrition research centre, the Alltech Coppens Aqua Centre (ACAC) in the Netherlands, which specialises in nutrition for recirculating aquaculture systems (RAS).”

Alltech continues its commitment to Working Together for a Planet of Plenty™ by partnering with companies like Finnforel to deliver smarter, more sustainable solutions for aquaculture, resulting in better nutrition and a decreased environmental impact. Backed by over 40 years of research and customer success, Alltech’s specialty feed ingredients and Alltech Coppens aquafeeds offer superior nutritional solutions for fish and shrimp. The ACAC in the Netherlands is one of Alltech’s five bioscience centres around the world.

“Finnforel and Alltech Coppens have been working together for several years on sustainable aquaculture

practices,” says Ronald Faber, CEO of Alltech Coppens. “This joint acquisition reflects the ambition of both companies, our shared values and the strength of our partnership.”

Finnforel also specialises in RAS, which allows producers to control water purity, temperature, stocking density and feeding while requiring 99 percent less water than traditional methods. The method’s indoor growing tanks provide a less stressful aquaculture environment that can be better controlled by aquaculture producers.

“I believe that Finnforel’s well-honed model, which works without antibiotics or environmental emissions, can support a significant part of this market,” says Pekka Viljakainen, chairman of the board of Finnforel Oy.

Aquaculture is an efficient way to produce nutritious protein for a growing population. As sustainable recirculating aquaculture systems are viable even in desert conditions, Finnforel’s aim is to export Finnish aquacultural expertise to the world in the coming years. Alltech’s and Finnforel’s acquisition of the Raisioaqua feed production facility will complete the circular-economy fish-farming chain in Finland and provide a replicable model for others.

“At the heart of Finnforel’s strategy are so-called gigafactories specialised in sustainable aquaculture,” says Mr Viljakainen. “In these aquaculture gigafactories, the entire production chain is in our own hands, from the parent fish and the eggs they produce to the consumer products.”

“Feed developed in accordance with the principles of a sustainable circular economy represents the last link in the chain,” adds Jussi Mekkonen, CEO of Finnforel Oy. “We have another new aquaculture facility that will be completed in spring 2023, after which we will be able to produce the eggs used in fish farming. Then, the entire fish-farming chain will be ready to be exported to the world.”

Norway releases full details of new salmon tax

On the 28th of March 2023, the long-awaited details of the salmon tax in Norway was finally announced by the Norwegian Government. It is decided that there will be a 35 percent VAT requirement for farms that harvest 4000-5000 tonnes, or more, per annum of salmon or trout as a resource rent. This incentive was created to provide social benefits by distributing a portion of the industry’s earnings to society, more specifically to the host municipalities, county council and the coastal towns that live among this culture. However, the salmonid farming industry is disappointed in the result of this being a 35% VAT.

Although this was reduced from an original 40 percent, “ It still gives a tax percentage of 57% (when 22% corporation tax is added),” said Robert Erikson, chief executive of Seafood companies. Furthermore, this reduction left the seafood industry in Norway unimpressed as it means that, according to Sondre Eide, General Manager of the company Eide Fjordbruk, who told the regional broadcaster NRK Vestla that a better scheme that could have been introduced by the government would be taxing a lower percentage on the conditions that the technology is more sustainable and therefore “The incentives could be given for technology development.”

However, the Norwegian prime minister, Jonas Gahr Støre (Labour), stated that the introduced tax should

still allow growth for the Norwegian salmon and trout farming industry. He also argues that salmon aquaculture can afford to be more heavily taxed due to the “extraordinary” profits that have been made by their impressive abilities that led them to be highly competitive in the salmon farming sector.

In spite of this, it can be seen as an advantage for countries like Scotland, Canada and Iceland, who are competition for Norway in the salmon and trout market, as Norway will lose investors to these countries and Norway will ultimately lose the edge that has maintained their success for centuries.

Although this was a disappointing result for Norwegian salmon farmers, it seemed to be expected according to a number of managers and was also said to be not much of a change.

Blue Aqua first in Singapore to Obtain ASC Certification

Blue Aqua has achieved the Aquaculture Stewardship Certification for their shrimp farming facility situated in Neo Tiew, Singapore, marking it as the sole farm in Singapore to receive this recognition for responsible farming practices.

This standard addresses the potential environmental and social impacts of farming, including loss of biodiversity, use of feed and water resources, disease management, and effects on local communities. To become certified, farms must demonstrate that they minimise their impact on the surrounding natural environment, limit the use of antibiotics, and adhere to social responsibility.

The urban in-land shrimp farm developed by Blue Aqua has allowed it to both limit environmental impact and create value as a result of land and sea water limitations. The 1.3 hectares farm currently produces 120 tonnes of naturally farmed shrimp annually being sold to restaurants and grocery chains island wide.

“At Blue Aqua our dedication lies in making considerable strides towards enhancing the sustainability of our farming

Bigger landing craft is direction of travel for salmon farmer

Scottish Sea Farms has taken delivery of its biggest landing craft to date, designed to support the company’s move to farms of fewer but larger pens.

The 19m Hollie Rose was built in Scotland by Bute Boatbuilders to a design by Argyll-based naval architect AG Salmon. The vessel, equipped with a PK32080 Palfinger crane and twin MD196TI Doosan diesel engines, will be based between Mull and Oban, and deployed across Scottish Sea Farms’ mainland estate, assisting with net washing, inspections and treatments.

In a first for Scotland, the boat is fitted with a state-of-the-art ROV

activities while striving to attain the utmost levels of environmental and social performance. We acknowledge that transparency holds a significant place, and we recognise the necessity to assess our progress in meeting our sustainability objectives.” says Dr Farshad Shishehchian, CEO & Founder of Blue Aqua International Group.

ASC is regarded as the most challenging and allencompassing certification available. To achieve ASC certification, farms must complete a rigorous performance assessment and meet over 500 compliance points.

Aquaculture operations that meet the ASC’s rigorous standards are awarded the ASC certification, which allows them to use the ASC logo on their products. This logo is recognised by consumers worldwide as a symbol of responsible and sustainable aquaculture practices.

“Obtaining an ASC certificate not only demonstrates our commitment to sustainable and responsible practices but also sets us apart in the marketplace as a leader in ethical aquaculture. With growing consumer demand for ecofriendly products, an ASC certificate will give our business a competitive edge while helping to protect the planet for future generations,” says Hamoon Shishechian, ESG Officer at Blue Aqua International.

(remotely operated vehicle) Manta net washer – supplied by Norwegian company Mainstay – that removes marine debris from pens during washing, helping create an optimum environment for fish.

The Manta net washing system also has hole detection software, recording any possible damage to the nets and further improving containment surveillance.

In another departure, the landing craft has on-board accommodation for two crew, enabling faster reaction times and greater flexibility.

Scottish Sea Farms Mainland Marine Engineering Manager Craig Cameron, who was involved in commissioning the new boat, said the Hollie Rose will be ready to go where needed at short notice.

“Having accommodation on a landing craft is new for us. It gives the

farms a better service and makes the vessel more flexible.

“The two crew will work two weeks on/two weeks off, which is becoming an increasingly popular working pattern in rural areas where housing is scarce.”

The skippers, David McKie and Jacob Ellis, were appointed via internal promotion, with each bringing 10 years’ experience with Scottish Sea Farms, most recently in managerial roles at Bloody Bay farm.

Mr Cameron said the company’s future landing craft are likely to be at least the size of the Hollie Rose, if not bigger, in line with the move towards installing wider diameter pens at farms.

Scottish Sea Farms installed its first 160m circumference pens at its Fishnish A farm, off Mull, late last year, with four of the larger pens replacing the 10 existing 100m pens, while maintaining the same biomass.

Brett Glencross Waste Not, Want Not...

Icame across an interesting statistic the other day, that the average UK citizen wastes more than 105kg of food each year. The notion that the average person in that country wastes more than their own weight in food each year to me seems horrific. But it seems that the Brit’s are not “special” in this regard, with most western/developed nations producing similar estimates of food waste from their national food systems. So, in a time when all costs seem to be rising, including that of food, never has there been a more urgent need to do something about “waste not, want not…”.

So, what to do? One modern mantra we often hear for dealing with waste (of any sort) is the “reduce-reuse-recycle” tagline. Notably, given the state of obesity in modern society, it is clear that many of us could start by adopting the first option and it would probably help solve two problems. But what about the reuse and recycle parts? How do we distinguish between what we mean by reuse versus recycle in the feed/food context. In an earlier column I wrote about how the process of reusing byproducts from human food production was now becoming a core

part of the modern marine ingredients sector. With about one third of all global marine ingredient production now coming from by-products. So, in this context what we mean is the reuse of those food grade products not desired for direct human consumption, so we turn them into indirect consumption, by feeding them to our future food.

In contrast to recycle a food product essentially means to convert the organic food biomass into energy or compost, through processes like biomass energy generation or composting. In these situations we end up liberating the nutrients and energy within those waste products, but at least we capture some benefit. In effect we recycle the nutrients and energy. The alternative options are a worst outcome still of course, where we either just burn it and not capture any energy or bury it in landfill. Unfortunately, and perhaps surprisingly, a lot of that still happens with many food products. From all these different use options, what we can note is that there is a clear resource use hierarchy on what we should do with food resources we don’t eat. Importantly, we can see that converting unused food resources to animal feed is one of the higher priorities.

While in the marine ingredients sector we are already well aware of constraints to expanding the availability of wildcapture marine ingredients, we are seeing an overall growth in our resource base. However it is less so from direct forage fisheries and more from the recycling of seafood biomass. Increasingly we are seeing seafood production chains valorise the by-products, as while this represents 50 percent or more of much of our fish processing, its small extra value is seen as the “cream on top” in terms of value creation from a product that until not that long ago was either burnt or buried. With this new resurgence in food recycling, the marine ingredient sector is now shining as great case study in being part of building a waste-free world. As we said earlier, “waste not – want not”.

Award-winning entrepreneur turns 70

The co-founder of Aller Aqua, Hans Erik Bylling, celebrated his 70th Birthday on 15 March 2023, and looking back at seven decades of being part of what began as a family business over 100 years ago, he is ready to embrace what will be the fourth generation of Byllings.

In order to create a good place for people to work and a space for them to excel, you need a genuine interest in people. This has been the guiding principle for Hans Erik Bylling since he took over the family business some 40 years ago. The proof is rather incontestable – 650 employees, activities in 70 countries and an annual turnover of €270m. The man behind one of the most impressive business adventures in Southern Denmark in the past decade has reached a milestone.

The foundation for the family dynasty was laid in 1912 when Bylling’s grandparents, Frederik and Ane Kirstine, took over the operation of the local mill, Aller Mill. The couple developed the business to include fodder for traditional farm animals, and after Hans Erik’s father, Hans Joergen, took over, high-quality fish feed was added to the portfolio, too. That, in particular, turned out to be a very good idea.

“My father succeeded in making dust-free fodder for pigs,” Hans Erik Bylling explains. “A Swedish consortium heard about it, and they asked him if he could develop a similar feed product for fish farming.”

Despite knowing next to nothing about fish metabolism, Hans Joergen took on the challenge, and over the following 20 years, he meticulously continued to improve and refine products for fish, slowly allowing the company to expand its radius of action. However, it wasn’t until the founders’ grandchildren, Hans Erik and his brother Povl, took over that the fish feed production turned into a true business adventure.

Saudi Industrial Investment Group (SIIG) to invest US$70 million on Unibio

Saudi Industrial Investment Group (“SIIG”) has signed an agreement to invest approximately US$70 million (GBP 59 million) in Unibio. This will enable Unibio’s vision of feeding the world’s growing population in a sustainable way. Unibio will use the funds to roll-out new global production capacity, grow operating capabilities, and accelerate innovation and commercialisation.

Through industrial protein production based on Unibio’s unique fermentation technology – the U-Loop® technology – it is possible to improve food security and feed the world’s growing population in a sustainable way without use of arable land and with low water usage. The fermentation technology mimics a process that occurs in nature every day and uses methane (e.g. natural gas or biogas) as feedstock. The production of Uniprotein® is efficient, stable, and independent of weather deviations that impact the production of traditional protein sources.

Uniprotein® is approved for feed in the European Union and global registrations are in progress. The protein provides nutrition on par with or better than other high-quality proteins, such as fishmeal, and has been tested successfully in various aqua and animal species. Uniprotein® is free from pesticides, fully traceable, and non-GMO. It has been launched commercially and Uniprotein® is attracting significant global interest from feed compound companies and animal and fish farmers. The production of Unibio’s protein for direct human consumption is under development.

Ace Aquatec and Ocean Health partner to develop FaunaGuard

Aquaculture technology specialists, Ace Aquatec, have partnered with marine ecosystem restoration specialists Ocean Health to further develop FaunaGuard, which uses academically validated sound patterns with award-winning transducer technology to create temporary exclusion zones around project sites. This ethical acoustic system is an important tool for safeguarding oceanic wildlife from the risks associated with offshore construction works. The two organisations now join efforts to make FaunaGuard globally available as the go-to mitigation solution for the offshore renewables sector.

FaunaGuard has been developed over a decade and has been deployed in many pioneering offshore construction campaigns, in order to protect marine life from serious physiological harm. Ongoing research, development and testing has given rise to a unique species-specific modular system, which unlike older generation acoustic devices:

Targets exact hearing ranges of fish, seals, porpoises, and turtles

Emits scientifically validated low-volume acoustics that do not cause hearing loss or deafness

Uses a series of complex tones to avoid habituation

Ensures the least physiological impact possible during subsea operations

Is fully compliant with the high standards set by the Joint Nature Conservation Committee (JNCC) in the UK and the Federal Maritime & Hydrographic Agency (BSH) in Germany

The Ace Aquatec and Ocean Health partnership will continuously seek opportunities for further development of the innovative technology and plans include adding new species-specific sounds.

FaunaGuard devices are typically deployed from a vessel to ensure animals are kept at a safe distance during other marine activities, such as pile driving, safe detonation of unexploded subsea ordnance, spawning protection, and removing oil spillages. Experts hail FaunaGuard technology as playing a vital part in protecting marine life offshore.

Andrew Gillespie, Marine Protection Products Business

Manager at Ace Aquatec, says, ‘We are seeing a marked increase in demand from environmental surveyors, contractors, and developers, who are specifying the need for more ethical solutions for safeguarding marine mammals from harm during construction projects. Our partnership with Ocean Health is accelerating change in the offshore sector to adopt a more species-specific approach to protection, rather than an outdated one-size-fits-all tactic’.

René Kersten, Program Manager at Ocean Health, adds, ‘The state-of-the-art technology used in FaunaGuard matches perfectly with our ambition to innovate the domain of ocean health. This partnership allows us to forge ahead with the development of new modules for additional species, so we are at the forefront of marine wildlife protection.’

FaunaGuard devices are due to be installed for Ocean Health next in the Baltic Sea from March 2023 onwards, with ongoing support from Ace Aquatec on monitoring marine life, having been recently deployed on CrossWind Hollandse Kust Noord project in the North Sea.

catfish

a more sustainable approach to feeding

Dr. Giovanni M. Cusimano, R&D&I Research Coordinator, AquaBioTech Group, Malta

AquaBioTech Group, a private Maltese aquaculture research, engineering and consultancy organisation, is a collaborator in a multi-partner Horizon 2020 project iFishIENCi. The project focuses on demonstrating the feasibility of new, sustainable feeds to support the growing interest in developing new production species, with higher growth and feed utilisation efficiencies.

To determine the performance and feed utilisation of hybrid catfish (Clarias gariepinus ♀ x Heterobranchus longifilis ♂) fed a novel yeast additive made from cultured Candida utilis, a nineweek growth trial was conducted. Preliminary results of this trial indicate that C. utilis could represent a suitable replacement of plant-based ingredients in hybrid catfish diet.

A growing demand for catfish

The FAO (2022) has identified catfish as an important and expanding sub-sector for aquaculture with production growing exponentially over the past several years, reaching 7.6 percent of the global inland aquaculture production in 2020. Although taxonomists recognise >3,000 species of catfish, only some of these contribute to the global harvest. The genus Clarias has been widely introduced to many countries beyond its native range, including Brazil, Cuba, Bangladesh, China, Philippines, The

Netherlands, and Hungary (who lead the European production with over 3000 tons/year). Although the use of the pure strain is widespread, the hybridisation process has drawn attention to improved production traits such as growth, feed utilisation, and disease resistance.

In the interest of more efficient production systems, improved sustainability, and reduced adverse environmental impacts there needs to be a reduction in the dependency on traditional raw materials (fishmeal and soybean meal) in aquafeed. Extensive research on microbial products, particularly yeast, is showing immense potential as a sustainable protein source for food or feed (Jones et al., 2020; Øverland & Skrede, 2016). Yeast is able

to convert low-value non-food waste biomass from forestry and agriculture into high protein feed with limited dependence on arable land and water.

The aim of this study was, therefore, to evaluate growth and feed utilisation performances when including single cell proteins at varying proportions in hybrid catfish feed.

Yeast additives as a feed solution

The experiment compared a control diet (42 percent protein, 12 percent lipid) consisting primarily of 80 percent

land-based ingredients (wheat, soybean meal, wheat gluten) and 17 percent animal-based ingredients (feather meal, fishmeal, fish oil, poultry oil) with two experimental diets where C. utilis was included at 10 and 20 percent respectively. A total of 140 specimens were randomly assigned to three replicate groups and stocked in 0.65 m 3 culture tanks within a full Recirculation Aquaculture System (RAS). The results of the trial showed a similar growth trend among the treatments with no significant differences recorded.

Great upgrade of your feeds!

The three tested diets were formulated to be isonitrogenous (42 percent crude protein) and isolipidic (12 percent crude fat) and manufactured by Research Diet Services BV. The inclusion level of primary protein sources is showed in Table 1.

Juvenile hybrid catfish (Clarias gariepinus ♀ x Heterobranchus longifilis ♂) were obtained in June 2022 from Győri Előre Halászati Termelőszövetkezet (Hungary) at a size of 0.4g and fed with a commercial diet until they reached the target size for the trial.

Fish of 77.7±0.25 g were randomly divided at an initial stocking density of 140 individuals per replicate 17kg m-3 and fed three times a day just below satiation for nine weeks. A bulk weight of all fish was performed after four weeks and at the end of the trial. Growth performances (FCR, SGR, PER, SFR) between the diets was then evaluated. Additional data collection of bio-morphometrics (K, fillet yield, VSI, SSI, HSI) and body colour intensity (L*, a* and b* coordinate) using Minolta Chroma-Meters CR-400 cat. 1878-209 was also performed.

The proof is in the pellets

Growth performance, bio-morphometric indexes and body colour intensity were analysed by one-way analysis of variance (ANOVA), using Jamovi software version 2.2.5 (The Jamovi Project, 2020), followed by post-hoc comparison by Tukeýs test for significance. The level of significance was set at p<0.05.

The experimental diets used during the trial were well accepted by the fish and no signs of low palatability were

recorded. End of trial growth performance biometric and morphometric indexes and body colour intensity are shown in Table 2 and Figure 1. The experimental diets gave similar growth results (p>0.05) and there is no evidence that candida meal inclusion reduces growth performance. In fact, 20 percent inclusion of candida meal showed slightly higher growth compared to control and 10 percent inclusion. The overall survival rate was >98 percent indicating an absence of negative effect of the treatments. Finally, the biometric and morphometric indexes revealed no significant difference among the treatments, while the body colour intensity showed a significant higher value of a* (red/green coordinate) of the 20 percent inclusion compared to the control diet.

A diversification of options

The aquafeed manufacture industry is still dominated by fishmeal and plant-based products but can now rely on a wider range of ingredients.

This experiment demonstrates the opportunity to provide a novel, more sustainable alternative for the industry that can relieve the environmental pressures on marine and land-based stocks. C. utilis has important nutritional value, possessing a high protein content (55 percent) and an interesting amino acid profile, including lysine (4.5 percent), threonine (3.0 percent), histidine (2.0 percent), and arginine (4.9 percent), as well as B-complex vitamins. Though non- significant, these results indicate that reduction of plant-based ingredients of about 14 percent and 28 percent, produced similar or slightly improved growth rates compared to the control diet. The palatability of the

tested yeast-based diets was in contrast with previous research conducted on fingerlings of African catfish, where an inclusion of 30 percent yeast showed low palatability and reduced feed intake (Elesho et al., 2021; Solomon et al., 2017). Although the results are promising, further investigation is required to evaluate the interaction among the ingredients in formulated diets, the relative effect on digestibility and the gut impact in hybrid catfish.

What's next for sustainable circular feeds?

The use of C. utilis and yeast in general as novel protein source has been widely investigated in valuable farmed species such as salmonids (Øverland et al., 2013; Refstie et al., 2010; Tukmechi et al., 2014), marine and freshwater fish (He et al., 2011; Li P, 2003/ 2004; Ortuno et al., 2002; Rodriguez et al., 2003; Tewary et al., 2011; Welker et al., 2012) showing an enhancement of growth performance, immune responses, and/or protection against bacterial infection. The growing interest of catfish farming worldwide and the development of related technology, make it a valuable candidate for further investigation.

These preliminary results will be integrated with further results of liver and gut histology, gut microbiome, and acute challenge test (ACT) using confinement stress. This multidisciplinary holistic approach will provide valuable information about physiology, feed utilization and stress tolerance of hybrid catfish fed with different inclusions of C. utilis.

Further investigation is needed to define the optimal inclusion of candida meal, the replacement of plant-based ingredients, as well as a market analysis on production costs of such ingredients at industrial scale to ensure the sustainability of yeast production as part of aquafeed, not only for catfish but for many high-value farmed species.

The use of chemotherapeutic agents and vaccines in aquafeeds; advantages and disadvantage

by Dr Simon J Davies, Nutritional Editor, International Aquafeed & Matt E. Bell, Marine Biology (Hons), University of Plymouth, UK

Chemotherapeutics such as antibiotics and medicines can be administered through the diet of farmed fish and shrimp species to prevent and treat various diseases. The use of these agents in aquaculture has increased significantly over the years due to the high demand for seafood products and the need to maintain the health of farmed aquatic animals. However, the use of chemotherapeutics in aquaculture has raised concerns regarding their potential impact on human health and the environment.

Antibiotics are commonly used in aquaculture to control and treat bacterial infections when necessary and especially in notifiable disease scenarios. The use of traditional vaccination route and especially for salmon and trout has employed various injection scenarios. These are however time consuming requiring additional skilled husbandry and are costly.

Antibiotics can be added to fish feed or water, and they

work by killing or inhibiting the growth of bacteria. However, the excessive use of antibiotics in aquaculture has led to the development of antibiotic-resistant bacteria, which can pose a risk to human health. In addition, antibiotics can persist in the environment and contaminate water sources, leading to the accumulation of residues in fish and shellfish. This can then lead to serious Anti-Microbial Resistance (AMR).

Another type of chemotherapeutic that can be administered through the diet of farmed fish and shrimp species is medicines such as antiparasitic agents and anti-inflammatory drugs. These agents can be added to fish feed or water to treat parasitic infections or reduce inflammation in fish. However, the use of medicines in aquaculture can also have negative impacts on the environment and human health. For example, some medicines may be toxic to non-target organisms or persist in the environment for long periods, leading to the accumulation of residues in fish and shellfish. Hence it is vital to test fish and shellfish tissues in validated laboratories prior to consumption.

To reduce the negative impacts of chemotherapeutics in

aquaculture, there is a growing interest in developing alternative approaches such as vaccines. Vaccines are a preventative measure that can reduce the need for antibiotics and medicines in aquaculture. Vaccine technologies for fish are diverse, and they can be delivered through various routes, including injection, immersion, and oral delivery.

Oral vaccines have gained attention in recent years as they are easy to administer and can be incorporated into fish feed. The use of oral vaccines in aquaculture can reduce handling stress and minimize the risk of infection during vaccination. Various studies have demonstrated the effectiveness of oral vaccines in fish species such as salmon, tilapia, and carp. For example, a study by Kumar et al. (2018) developed chitosan nanoparticles loaded with a DNA vaccine against Aeromonas hydrophila, which were incorporated into fish feed and fed to Indian major carp. The study showed that the oral vaccine was able to induce a significant immune response and protect the fish against the bacterial infection.

Despite the advantages of oral vaccines, there are several challenges involved in their development and use in aquaculture. One challenge is ensuring the stability and efficacy of the vaccine in the harsh environment of the fish gut. The vaccine must also be able to stimulate a systemic immune response and provide protection against the target pathogen. In addition, the cost of developing and producing oral vaccines can be high, which may limit their availability and adoption in some regions.

humidity, and light.

2. Dosage: The dosage of the active ingredients in the feed must be sufficient to achieve the desired therapeutic effect. It is important to determine the optimal dosage for each active ingredient and ensure that it is consistent in each batch of feed.

3. Coating: One way to protect the active ingredients from degradation is to coat them with a protective layer. This can help to maintain their stability and efficacy in the feed.

4. Processing: The active ingredients should be added during the feed manufacturing process to ensure that they are evenly distributed throughout the feed. This can be achieved through methods such as spraying, mixing, or pelleting.

5. Storage: The feed should be stored in a cool, dry place to prevent degradation of the active ingredients. It is important to monitor the shelf life of the feed and discard any expired or degraded product.

Overall, it is essential to work closely with a qualified veterinarian or fish health professional to ensure that the active ingredients are appropriate for the target fish species and that the feed formulation and manufacturing process are optimized for maximum stability and efficacy.

Adding oral vaccines and drugs to compound fish feed requires careful consideration of the stability and efficacy of the active ingredients. Here are some general guidelines to consider:

1. Stability: The active ingredients must remain stable in the

In conclusion, the use of chemotherapeutics such as antibiotics and medicines in aquaculture has raised concerns regarding their potential impact on human health and the environment. Alternative approaches such as vaccines, particularly oral vaccines, are being developed to reduce the reliance on chemotherapeutics in aquaculture. While oral vaccines have shown promise in preventing and controlling diseases in farmed fish and shrimp species, there are still several challenges that WWW.AQUARIUSLAWYERS.COM.AU

AquaSafe Integrating sustainability and fish health

by Antonio García, Nutrition, Health and Animal Welfare Service Manager, Dibaq Aquaculture, Spain

As a result of innovation and continuous improvement, Dibaq announces a new product lineDibaq AquaSafe ®, in which we have been actively working in recent months. It is an internal quality seal to differentiate our high-value products.

The seal of Dibaq Aquaculture has always been of a valuable company, specialised in the manufacture of special and differentiated products, using high quality raw materials, micronutrients and functional components. However, as a result of the innovation and needs of our global market, we have managed to go further and improve the quality of our nutrients, additives and formulas in our products with this new seal that aims to provide value and differentiation to our clients and achieve them the maximum performance in their production.

This concept includes the sustainability and safety of water and Planet Earth, as well as the health and safety of fish fed with our products, stimulating the immune system, protecting them against internal and external parasites and improving productive

and presence of internal intestinal and external branchial pathogens and parasites.

Sustainability: focuses on compensating for the needs of the present without compromising the ability of future generations to meet their own needs. It is made up of three pillars: economic, environmental and social. At Dibaq Aquaculture we have adopted an environmentally responsible policy by including fishmeal and fish oil from sustainable fisheries along with the inclusion of alternative protein sources. In this way, we help our clients in their goal of being potential and sustainable protein producers for world production. Last but not least, our manufacturing method is environmentally friendly by minimizing and reusing waste and using 100 percent recyclable bags.

Technology; Improvement and expansion of micro-pellets in hatchery products: the size of the individual particles of a granule and, therefore, the degree of grinding of a food have an important effect on the digestibility of the raw materials of the feed, increasing it and, consequently, improving the productive results. Obtaining our new line of Microbaq AquaSafe segmented and adapted for different species is especially beneficial for carnivorous fish, having a short digestive tract, and for larvae and fry.

Digestive and Functional Activity: It is summarised in an improvement in the nutritional quality of the feed through proteases, nucleotids, short chain fatty acids, organic minerals and natural additives that optimize its use in the digestive tract. In addition, it allows a correct intestinal health in high diets of vegetable flours, using less fish meal and lowering costs to the client and improving the performance and the immune status of the fish, besides improving sustainability.

Among the examples of nutraceutical and antiparasitic activity we have the following AquaSafe products.

AquaSafe 4Tress

In addition to stimulating immunity, due to it favours the intestinal health of fish, which leads to a better nutrient absorption surface, and an increase in growth, as well as better microbiota and cellular immunity, the products that contains this natural additive are effective against internal parasites, such as myxosporidia in the intestine (E. leei) (image 1).

In comparative trials with different batches of sea bream fed with control feed or DIBAQ AquaSafe® 4Tress, it was observed that at the end of the trial, some of the animals in the group fed with control feed showed what it is called "knife syndrome" or extreme thinness, caused by the intestinal Myxozoo called Enteromyxum leei.

In image 1, in sea breams of the control feed, the villi appeared very thickened and even fused as a consequence of the inflammatory process caused by the parasite. It is observed in the final control image that the intestinal mucosa does not occupy more than half of the intestinal lumen.

In contrast, sea breams fed with DIBAQ AquaSafe®4Tress showed an increase in the mucosal surface that covers practically the entire intestinal lumen. This is due to the increase in the length of the villi and the depth of the crypt, as shown in the photos. The inflammatory process and the parasite load are reduced.

Compared with the appearance of the intestinal mucosa at the beginning of the experience, the DIBAQ AquaSafe® 4Tress food have a beneficial effect on the intestinal surface, which favours a greater capacity for nutrients absorption, and with it an improvement in growth. The increase in cell turnover, improves the elimination of intracellular parasites such as protozoa (E. leei), reducing the parasite load and secondarily the inflammatory

reaction, avoiding symptoms such as weight loss and mortality. It is concluded as a tool for the control of this parasite.

Regarding its internal antiparasitic function, it is recommended at times of rise in temperatures in summer, since in the transmission of E. leei, the temperature of the water plays an important role, verifying an evident relationship between temperature and prevalence. Low temperatures have an inhibitory effect on the development of enteromyxosis, but the infection usually reappears when the temperature rises again in spring. For this reason it is a good option if the fish stocked from April-May are given AquaSafe 4Tress from the beginning and for several months. Afterwards, we can rest for several weeks and use it again until the temperatures are low again.

In image 2, in a test using sea bream and sea bass, it was found that mortality was lower in fish that had been fed with Dibaq AquaSafe 4Tress, due to its immunostimulating effect.

During the same test, the SGR (specific growth rate) was measured. Image 3 shows a higher final weight gain in seabreams and seabass fed with DIBAQ AquaSafe® 4Tress. This additive shortens the production cycle, as the fish reach their selling size sooner.

AquaSafe Br

This product, made up of several specific natural additives for gill parasites (monogeneous), is recommended to be used in the time of greatest prevalence, that is, with increases in temperature from spring, being especially recommended during the summer months.

In image 4, in the results of a test carried out with two control feeds and AquaSafe Br in sea bream, we see how the prevalence of gill parasite infection, that is, the number of infected fish, is lower in fish fed with the products with Dibaq AquaSafe Br.

AquaSafe S

Another one between our nutraceutical and health products, among the recommendations to give this product to the fish, are at times when you want to boost growth, prepare them for stress situations (prior to biometrics, manipulations, storms) and reduce intestinal and general inflammation of the organism that usually causes a form of intensive production as occurs in aquaculture.

Between the AquaSafe concepts, we give priority to animal welfare and the prevention of parasitic, bacterial and virological diseases, through the best possible diet. For best results, the use of our products and natural additives with immunostimulating, antiparasitic, antistressing, anti-inflammatory and growthpromoting functions should be based on the way of production, epidemiological history, handling and characteristics of each farm.

A hitchhiker’s guide to floating marine debris

by DEFRA (Department for Environmental Food & Rural Affairs), UK

The threat to UK waters could be reduced as pioneering research led by the Centre for Environment, Fisheries and Aquaculture Science (Cefas) and funded by Defra sheds new light on invasive species 'hitchhiking' across the sea on floating marine debris, such as plastics. In some cases, certain species are thought to have travelled from as far as the east coast of America, thousands of miles away.

By adapting a computer model originally designed to predict the distribution of oil following an oil spill, Cefas scientists were able to uncover the origin of floating marine debris and track how invasive species enter UK waters.

There are 39 recorded marine non-native species, including the Slipper Limpet and Signal Crayfish, considered as harmful to UK native marine biodiversity. It is hoped this advanced modelling technique will enable the UK and countries worldwide to track the movements of debris and pave the way for an early warning system to prevent and respond to emerging threats from nonnative species more accurately.

Plastic; the main Villain

With 80 percent of marine debris made up of marine plastics, and over 800 million tonnes of plastic ending up in our oceans each year, this research reiterates the importance of tackling global plastic pollution, supporting calls from Environment

Secretary Thérèse Coffey at the UN Conference of Biological Diversity (CBD) COP15 last year for greater ambition and support to protect 30 percent of the world's ocean by 2030.

International Marine Minister Lord Benyon says, “This research sheds light on a lesser-known consequence of plastics and litter entering our ocean, with floating debris threatening valuable marine biodiversity by transporting invasive, non-native species into the UK.

“It underlines the importance of global action that impacts our marine life and the UK is at the forefront of these efforts, mostly recently in championing calls to end plastic pollution by 2040.”

In this first of a series of leading research papers, Cefas scientists used a large piece of marine debris collected off the southwest coast of the UK to identify animals, including goose barnacles, hitchhiking their way into UK waters from sub-tropical and tropical waters generally below 40 degrees latitude.

Using the date, the piece of debris was found, and growth rates of the animals attached to the debris, scientists were able to calculate the time the debris had travelled through the ocean and 'back-track' its journey and likely origin. This has enabled the identification of 'hot spot zones' along the southwest coast (where many of these species from the tropics make first landfall) containing a high concentration of marine debris that can pose a greater risk of transportation of invasive, non-native species.

Dr Peter Barry, Marine Ecology Scientist at Cefas and lead author of the report says, “While this type of hitchhiking movement has been identified among various species and

Invasive species are recognised as one of the greatest threats to marine biodiversity worldwide, second only to habitat loss, and cost the UK economy GB£120 million a year.

regions before, there is still a lot we don't know about how invasive species enter our waters. A real challenge for scientists has been to identify where the hitchhikers have come from. This model allows us to retrace their journey to understand where and how an invasion pathway is operating.”

“Although not all non-native species entering the UK will become established, those that do can be incredibly harmful for the environment. With the increase in marine litter in our seas, it's important for us to understand how these species are being transported, and to identify areas most at risk to help prevent their spread.”

More research to tackle the issue

Cefas will now research how invasive species can be transported on other marine debris such as seafloor litter, complementing work taking place internationally to better understand the sources of marine debris and how these enable invasive species to spread.

The UK continues to be a leading voice in tackling marine plastic pollution, co-sponsoring the proposal to prepare a new international, legally binding plastics treaty and is a founding member of the High Ambition Coalition to End Plastic Pollution, a group of 50 countries calling for a target under the treaty to stop plastic from flowing into our lands and ocean by 2040.

The UK took an ambitious stance at the Intergovernmental

Negotiating Committee (INC1) in November last year, pushing for a treaty that will restrain the production and consumption of plastic to sustainable levels, address plastic design, and encourage more recycling and re-use of plastic.

In December last year, the Environment Secretary Thérèse Coffey attended the UN Conference of Biological Diversity (CBD) COP15 in Montreal where she called for greater ambition and urged more countries to join the more than 120 nations who already support the pledge to protect 30 percent of the world's ocean by 2030.

REDEFINE PRECISION

IN AUTOMATIC DOSING

An analysis on THE latest marine ingredient market trends

Ataste of the many statistics and analyses that can be found in the market intelligence reports that IFFO dedicates to its members. They include an analysis of both the supply and demand sides of the market, with research focusing also on the global trends of animal farming and fish catches, agricommodities, commodities’ prices and general macro-economic conditions. A specific and additional focus is made on China given that China is by far the main market for marine ingredients. For the regions for which IFFO regularly tracks production of marine ingredients, roughly worth 50 percent of the global output, we found that total cumulative output of fish oil in the first 11 months of 2022 was up with respect to the cumulative production reported through November 2021. The European countries, India, the USA as well as South Africa, Ivory Coast and Mauritius were the regions that reported a year-over-year increase. Cumulative total fishmeal production for the first 11 months of 2022, was down compared to November 2021. This is mainly due to a late start of the 2022 second fishing season in Peru. The USA, India, the Iceland/North Atlantic area and the African countries were the regions considered that have increased their cumulative production with respect to the same period in 2021.

In December 2022, Peruvian catches were in line with those reported in December 2021. This means that the deficit of around 1.15 million metric tonnes of raw material reported until November 2022 vs January-November 2021 has not been reduced in Peru, negatively affecting the overall performance for the year 2022.

China’s marine ingredients production remains subdued

Domestic production of marine ingredients was adjusted downwards throughout the year 2022: production ended up being smaller than in 2021. 2023 has so far shown the same conditions. Total offtakes of imported fishmeal from ports’ warehouses in 2022 were estimated higher than during the same period in 2021.

Aquafeed production in 2022 was reported over 23 million metric tonnes, a slight increase year on year. January and February are traditionally off-season for the aquaculture, as temperatures are too low and national holidays kick in. Therefore, fishmeal demand from the aquafeed sector remains limited. The beginning of the year is usually the time when aquafeed producers stock feed ingredients in view of the new aquafarming season starting in March-April.

Both the pig and pork prices declined in 2022 because of oversupply and weakened demand. 2023 has not been different so far as the massive Covid contagion has greatly affected foodservices, the main consumer of pork products. Sow stock remains high, potentially giving birth to a bigger number of piglets. This would play in favour of pigfeed demand and in turn of fishmeal consumption.

China is the largest aquaculture producer in the world, with the production accounting for about 60 percent of the global aquaculture production. The rapid development of aquaculture has also brought many ecological impacts. For example, the input of a large number of marine fishery resources in aquaculture has become a research highlight in recent years. By field research and literature analysis, the status and trend of using marine fishery resources in aquaculture and the input quantity of marine fishery resources in aquaculture in China are researched. This research reveals that 35 percent of total catch and half of the trawler catch

in China are low value "feed fish". These feed fish are mainly used for direct feeding or producing as fishmeal material in aquaculture. The efficiency of utilizing marine fishery resources in aquaculture is relatively high in China. FIFO (Fish In: Fish Out) is only 0.25, slightly lower than the average 0.27 (Naylor et al 2021) in the world. Therefore, it is still one trend to reduce the input of marine fishery resources in aquaculture in China.

China’s fishmeal production has increased, and environmental and quality measures are now being put in place. Tailored regulations have been developed with the industry, including testing and monitoring of compliance. Fan gave an overview of

the new fishmeal standard in China, looking at quality and safety indicators. Enhancement of the new standards in the industry, along with further strengthening of supervision, will improve the fishmeal production environment and rational addition of fungicides/bacteriostatic agents. Fan noted that fishmeal is a very globally diverse product and therefore more diverse standards may be needed in the future. Further strengthening safety access and risk analysis of fishmeal, will promote the healthy development of feed production, animal husbandry and aquaculture in China.

Fishmeal production over the last few years has been around 600,000 metric tons, with production being stable over the last 7 years and a good part of production coming from salmon trimmings.

contributed to the production of 7kg of fish per capita, and 30 to 40 million tonnes of additional feed ingredients are estimated to be needed in aqua feed globally by 2030. According to the latest research and analysis methods, marine ingredients clearly hold comparative advantages in terms of sustainability and environmental impacts, which makes it an important player of all responsibly sourced feed ingredients, to collectively support the aquaculture sector, whose growth is seen as a key to the Blue Transformation which is FAO is calling for. fishmeal supply and demand in Europe, including the production of fish meal in Europe and raw material expectation for 2022 and 2023.

Fishmeal production over the last few years has been around 600,000 metric tons, with production being stable over the last 7 years and a good part of production coming from salmon trimmings. Blue whiting is a key raw material and due to lack of political agreement is now under a Fishery Improvement Project (FIP), but the quota has now been increased by 81 percent this year showing a healthy stock. For capelin, catches around Iceland suddenly increased in the last year but quotas are reduced again for 2023. Lastly, by-products from trimmings (herring, white fish and farmed salmon) are contributing 30 to 40 percent of sustainable raw material for Europe.

Integrating business with science and civil society

The 14th edition of the Monaco Blue Initiative (MBI) kicked off ‘Monaco Ocean Week’ in Monaco on March 20, 2023

This year’s MBI brought together nearly 180 ocean stakeholders to address, in both concrete and operational terms, the current and future global challenges of ocean management and conservation.

As reported in Prince Albert II of Monaco Foundation's March 2023 e-Newsletter, this year’s event was held in a spirit of celebration following recent international progress and, in particular, the announcement of the newly agreed United Nations’ treaty on the high seas.

The 14th MBI also addressed possible solutions for ocean conservation and a sustainable way forward for the 'blue economy.' Sustainable fisheries, highly protected marine areas, restoration of marine ecosystems and solutions for a protected Mediterranean were at the heart of the discussions at this year's meeting.

In his opening speech, HSH the Sovereign Prince, Prince Albert II, stated that "Significant progress has been made over the last few

months. I am of course referring to the adoption of the High Seas Treaty by the United Nations on 4th March.

“Thanks to this agreement, we will at last have the legal tools available that will help us protect international waters more efficiently, by being able to establish marine protected areas in the high seas, which I have long been calling for, whilst at the same time allowing for the equal sharing of benefits from marine genetic resources.

“In the wake of what we have already accomplished on an ad hoc basis, for example in the Ross Sea in Antarctica, this is an important perspective for the most endangered ecosystems, for all the seas of the world, and for the entire natural balance of the Planet.”

Those present

Several high-level personalities were among the speakers including: Rodrigo Chaves Robles, President of Costa Rica; Huang Runqiu, Chinese Minister of Ecology and Environment; Jean-François Ferrari, Designated Minister for Fisheries and Blue Economy, Seychelles; Teresa Ribera Rodriguez, Third Vice-President of the Government of Spain and Minister for Ecological Transition and

The meeting was divided into four sessions on the following topics:

• Sustainable fisheries and reconciling conservation and exploitation in the next decade and beyond;

• Highly protected marine protected areas (MPAs) - what is at stake and the vision for 2030;

• The role of marine ecosystem restoration in achieving the UN's Sustainable Development Goals;

• Raising ambition and scaling solutions for a protected, resilient and sustainable Mediterranean Sea.

The 14th edition of the Monaco Blue Initiative was closed by its co-organisers.

Robert Calcano, CEO of the Oceanographic Institute told delegates,

"Working with scientists and civil society remains crucial, but we need to integrate businesses, which are major, indispensable players for the preservation of the Ocean.

“The need for cooperation with private players has been apparent throughout our exchanges on topics from sustainable fishing to the restoration of marine ecosystems.

“In each of these cases, the private sector draws a dynamic link between various interested parties."

Olivier Wenden, Vice-President and CEO of the Prince Albert II of Monaco Foundation also added, "There is a momentum to urgently level up action and funding, mainstreaming biodiversity conservation, to meet the goals of the Global Biodiversity Framework and protect 30 percent of land and seas by 2030.

“Our exchanges in this respect were rich and perfectly echoing the priorities of the Foundation – which I am certain we all share: scaling up and accelerating existing solutions. But also better regulated and better shared scientific data.

“How? Through innovation and through a transversal and holistic approach," he concluded in the report published in the e-Newsletter.

Mrs Genevieve Pons, the director of the Brussels Office for Notre EuropeJacques Delors Institute told delegates attending the MBI held on March 24-25, 2019 of the benefits from large-scale Marine Protected Areas (MPAs)

At the previous MBI, held on March 24-25, 2019, the UN Secretary General Ban Ki-moon was quoted from a statement made in 2015 on his belief that the high seas should be best protected by nations “… acting in the global interest.”

FISH FARMING TECHNOLOGY Tech update

FaunaGuard

Aquaculture technology specialists, Ace Aquatec, have partnered with marine ecosystem restoration specialists Ocean Health to further develop FaunaGuard, which uses academically validated sound patterns with award-winning transducer technology to create temporary exclusion zones around project sites. This ethical acoustic system is an important tool for safeguarding oceanic wildlife from the risks associated with offshore construction works. The two organisations now join efforts to make FaunaGuard globally available as the goto mitigation solution for the offshore renewables sector. FaunaGuard has been developed over a decade and has been deployed in many pioneering offshore construction campaigns, in order to protect marine life from serious physiological harm. FaunaGuard devices are typically deployed from a vessel to ensure animals are kept at a safe distance during other marine activities, such as pile driving, safe detonation of unexploded subsea ordnance, spawning protection, and removing oil spillages. Experts hail FaunaGuard technology as playing a vital part in protecting marine life offshore.

Shellfish

An overview of selective breeding

by Jyothsna Nelloolichalil, International Aquafeed, UK

About 100 years ago, agricultural scientists in the US discovered the advantages of inbreeding naturally outcrossing (windpollinated) crops, such as maize or corn, and then crossing the inbred lines to produce vigorous, high-yielding, uniform hybrid plants. Crossbreeding of corn in the US resulted in a 7-fold increase in yield for the maize industry and is the basis for most crop and even some livestock (poultry and swine) improvement. High-yielding hybrids cannot be achieved by simply selecting higher-yielding parents, because hybrid vigor depends not on the general effects of the parents’ genes, but instead on the specific combination of parental genomes in their offspring.

Having demonstrated that shellfish show hybrid vigor as many plants do, researchers tried crossbreeding to increase harvest yields and improve resilience to changing ocean temperature and chemistry. Hybrid shellfish will positively impact the success and security of shellfish farmers in the Pacific Northwest and around the world.

Why and how?

One of the foundations on which agricultural production is based on is genetic improvements and animal breeders have been performing selective breeding since centuries through the selection of individuals demonstrating unique or high quality

traits as parents for the next generations. Eastern oysters have been subjected to genetic breeding since a long time as they are high fecund and their population generally harbours substantial genetic variation for commercially important traits. The main goals of breeding programmes for fish and shellfish are to increase the profitability and sustainability of aquaculture. These have historically been effectively carried out using pedigree data by choosing parents based on breeding values expected for characteristics assessed on applicants using an "animal model."

According to this approach, traits can be accounted for by a large number of genes with modest impacts and a wide range of environmental variations. Information on specific genes with moderate or significant impacts, however, cannot be used in this way. Molecular markers have been used mainly for parentage assignment in selective breeding schemes using pedigree information when tagging individual fish is challenging and to prevent common environmental impacts from raising families in separate containers. The application of these methods in such traditional breeding schemes is thoroughly explored.

Different experimental designs may use chromosomal manipulations or large family sizes to increase the likelihood of finding the loci affecting quantitative traits, the so-called QTL, by screening the segregation of molecular markers. These

strategies take advantage of the great biological diversity of many fish and shellfish species. When compared to conventional breeding techniques, using information on identified loci in aquaculture breeding systems is only anticipated to be more cost-effective when the precision of forecasting breeding values is relatively low, such as for characteristics with low heritability like disease resilience. One issue with aquaculture is that some of the tools needed to precisely identify QTL, like dense linkage maps, are still not accessible for all of the species. However, recently, data from EST libraries has been utilised to create molecular identifiers like microsatellites and single nucleotide polymorphisms. (SNPs). Genome-wide marker-assisted selection (G-MAS) or marker-assisted selection (MAS)

It is difficult for plant breeders to determine an optimal breeding strategy given that the problem involves many factors, such as target trait genetic architecture and breeding resource availability. There are many possible breeding schemes for each breeding program.

FAO estimates that there are around 200 species in aquaculture. However, only a few species have ongoing selective breeding programmes. Marker-assisted selection (MAS) is not used in any aquaculture breeding scheme today. Genetic marker maps have been published for some species in culture. The marker density of these maps is, in general, rather low and the maps are composed of many amplified fragment length polymorphism (AFLP) markers anchored to few microsatellites. Some quantitative trait loci (QTL) have been identified for economically important traits, but they are not yet mapped at a high density. Computer simulations of within-family MAS schemes show a very high increase in genetic gain compared with conventional familybased breeding schemes, mainly due to the large family sizes that

are typical for aquaculture breeding schemes.

Revolutionising breeding with DNA insights

Recently a Roslin institute developed extensive generic resources that details the DNA of oysters which can be used in addressing the challenges oysters face. The research identified two areas of oyster genome that is significantly more associated with growth increase. The incorporation of genomic information into breeding schemes could be a cost-effective way of enhancing growth traits such as weight and shell size in oysters.

The researchers decoded the DNA code of European flat oysters to identify the high-quality reference genomes and analysed the genome to assess whether it is linked to improving growth traits in oysters. The team explored areas of the oyster genome previously linked to resilience to the parasite and identified an area that was strongly associated with resilience to the parasite. Although long in decline, oysters were once an abundant food supply and a staple of the Scottish people. The study at the Roslin Institute used genomics and genetic techniques to help guide breeding plans of the native European flat oyster in cooperation with UK and European scholars, business, environmental organizations, and government scientists.

Conclusion

Like all of aquaculture, the shellfish industry needs to grow into a successful farming endeavour that uses domesticated and enhanced stocks that cannot interbreed with natural stocks. In order to achieve this, the industry will need to be restructured, commercial breeding projects and firms will need to be established, and new marketplaces for improved seed will need to be developed.

Agreement on ten-year plan for sustainable growth of mangrove oyster production in The Gambia

Better oyster production and responsible resource management are vital for sustainable growth of The Gambia’s mangrove oyster sector, according to an upgrading strategy endorsed by key stakeholders. The agreement marks the start of FISH4ACP’s activities in support of female oyster producers, while aiming to turn the tide on declining oyster stocks.

by Aquaculture Stewardship

“This agreement bolsters our support to Gambia’s oyster sector,” says Fanta Bojang Samateh, Deputy Permanent Secretary of the Ministry of Fisheries, Water Resources and National Assembly Matters, opening a meeting where a 10-year strategy to upgrade the oyster value chain of the West-African nation was endorsed. He adds, “It is of great importance for the women who dominate

this sector, allowing them to feed their families and improve their livelihoods.”

The agreement is the fruit of joint efforts of public and private sector representatives of the Gambian oyster value chain and FISH4ACP, a global fish value chain development initiative of the Organisation of African, Caribbean and Pacific States (OACPS) implemented by FAO with funding from the European Union (EU) and the German Federal Ministry for Economic Cooperation and Development (BMZ).

“The European Union is delighted to be part of this endeavour, aiming to improve the lives of female oyster producers and contribute to restoring natural resources in such precious habitats as the mangroves,” says Evangelina Blanco González, Programme Manager at the EU Delegation to the Gambia. She adds, “FISH4ACP’s holistic approach to value chain development is a great example of the sustainable development that the European Union supports.”

The upgrading strategy lays down an ambitious roadmap for the sustainable development of oyster production in The Gambia

Council, UK

over the next ten years, extending well beyond the duration of FISH4ACP, which is set to close by end in 2025.

The strategy contends that growth is possible because of increasing demand on the local market, but stresses that improved and participative resources management is essential to make the exploitation of wild oysters more sustainable and to address decreasing oyster stocks.

At the same time, The Gambia’s emerging oyster aquaculture sector will be supported with financially viable new production methods, an increase in the number of oyster farms, as well as an update of the framework regulation oyster farming.

Pilot schemes to trial the sale of new oyster products, such as fresh oysters or oyster shells for poultry feed or jewellery

products, as well as the exploration of new marketing channels will feed into a market strategy for the oyster, which will be based on robust product hygiene standards for consumer safety.

Market development will go hand in hand with improvements in equipment and infrastructure. These will be partly financed by value chain actors themselves, who will be supported to get better access to financial resources.

“The agreement reached today underpins our resolve to transform the oyster sector into a sustainable venture,” says Moshibudi Rampedi, FAO Representative in The Gambia. She adds, “FISH4ACP shows how we can make the oyster value chain resilient and meet a growing demand for nutritious, safe and affordable food, while maintaining sustainable ecosystems and leaving no one behind.”

VIV Asia 2023 30th Anniversary

VIV Asia 2023 was an incredible success with an amazing number of attendees and exhibitors. Held in Bangkok, Thailand at the IMPACT Challenger, the B2B event spanned over three days from March 8-10, with an additional day for a few conferences on March 7.

The complete feed to food global trade show saw a staggering number of attendees with a registered 47,527 visitors from 112 countries and 1,186 exhibitors from 57 countries. The exhibition was split into sections, ranging from animal health, farm production, aquaculture, machinery and more in a space of 31,544sqm across three Challenger halls. Many of the exhibitors had a range of products on display, such as machinery and feed, and some even gave free samples to their products to the visitors.

Plus, with VIV Asia offering over 120 conferences and sessions, there were a range of topics for everyone to have at least one event that would interest the. Each conference covered the latest information and insights into the newest insights, innovations, and technologies. Some of the conferences that were held were ‘How to Build your Sustainable Dairy Farm’ by Global Dairy Farmers, ‘Trends, Challenges and Opportunities of Alternative Proteins in Asia’ and many more, along with some created by our own company.

“VIV Asia is the first VIV show in 2023 and it represents – and rightfully so – our goal to connect the markets, and enhance industry trade both locally and globally,” stated Birgit Horn, Managing Director of VIV Worldwide, during the event.

Our Conferences

Perendale Publishers, parent company to Milling and Grain magazine, organised three separate conferences: Aquatic, 7th Annual Aquafeed Extrusion (7AQE), and Build My Feed Mill. All three conferences were an incredible successful, with two of them being a full house and the third being half full at minimum.

Aquatic and 7AQE were both held on the same day, March 7, and lasted the whole day. VIV and Progressus worked together with Perendale to organise Aquatic while Dr Mian Riaz of Texas A&M University worked with us on 7AQE. Both conferences were a great starter to VIV Asia which began the day after on March 8.

Build My Feed Mill was a two-hour conference held on the morning of March 10 that was solely organised by Perendale. This was an amazing conference with full attendance and a fantastic way to end the exhibition.

Full reports on the three conferences will appear in the next edition of Milling and Grain so make sure you read the next edition to find out more.

30th Anniversary

VIV Asia 2023 celebrated the 30th anniversary of VIV in the Challenger 3, VIV Square on the second day of the event, March 9. The celebration began with a spectacular dance performance, followed by a warm welcome to all attendees with free food, drinks and gifts upon entry into the VIV Square.

Managing Director of VIV Worldwide, VNU Europe, Mrs Birgit Horn, then introduced the small event and presented Mr Chris Jackson, Export Manager for UKTAG, the UK’s Technology for Agriculture and Genetics organisation, an award. For Chris’ ‘outstanding contribution to VIV and the foodto-feed industry’ along with being the UK’s representation for guidance and commitment to VIV since its inception in 1993 in Japan, he was awarded with a trophy and travel-sized suitcase as a sign of appreciation from VNU.

Following this, it was announced by Mr Igor Palka, Managing Director of VNU Asia Pacific and Mr Jose Gerardo Feliciano, Vice President of United Broiler Association, that ILDEX Philippines and the Philippine Poultry Show will be combining into one event- Philippine Poultry Show & ILDEX Philippines 2023.

Triumphant Time

This year, VIV Asia was held in a new location and despite this, the animal protein sector responded to this change incredibly with attendance from both exhibitors and attendees not being affected negatively and remaining high. The show also offered free transportation to and from the event with the use of a shuttle bus to the sky train stations located throughout Bangkok to assist anyone who struggled to find transport as the area had lots of traffic.

“It’s always pleasing when a new trade fair is warmly received, and this was certainly the case with this first edition of Meat Pro Asia,” adds Mr Richard Li, Executive Director, Messe Frankfurt (HK) Ltd.

The halls were packed every single day with attendees and exhibitors, with many companies to visit and conferences to attend. We managed to meet a lot of these companies, such as Ottevanger, Dr Eckel, PLP Liquid Systems and so many more. We reinforced our relationships with our Global friends and created new ones too.

We also conducted multiple interviews with various companies, ADM’s Vice President of Feed Additives- BK Chew and Famsun’s Director- Liu Guandao along with audible interviews with ADM’s technical sales managers- Gunduz Ilsever and Luiz Souza. You will be able to see these interviews soon on our websites, future editions of Milling and Grain and our socials.

Next Time

The next VIV Asia will be held in 2025 on March 12 – 14, however the next VIV event will be VIV Nanjing 2023 on 6 -8 September in Nanjing, China. VIV is run by the amazing organisers VNU Worldwide who organise multiple events per year, all of which being successful. VNU will be hosting another event sooner than VIV Nanjing though called Philippine Poultry Show & ILDEX Philippines 2023 on June 7 – 9 in Manila, Philippines.

Aquaculture America

WAS held another successful Aquaculture America this February 23 to 26, in New Orleans, Louisiana, USA at the New Orleans Marriott. The conference and exposition is the largest trade show for aquaculturalists in the western hemisphere, with nearly 200 booths attending. It provided a great opportunity for attendees to catch up on the latest products and services in the industry, as well as meeting suppliers and familiar or new faces.

The event also provided an extensive technical program, including sessions, papers, and workshops on aquacultural issues. Topics ranged from Biotechnology/biogenetics, conservation, management, stock enhancement, food safety, health and disease, economics, marketing, engineering, nutrition, water quality, and species-specific information.

The Conference was also the site for meetings organised by the Aquacultural Engineering Society, Aquatic Drug Approval Coalition, US Trout Farmers Association, Zebrafish Husbandry Association and many more.

There were ample networking opportunities throughout. Experts were offered the chance to present their papers, in either poster presentations or oral presentations. The attendees ranged from Students and professionals to experts in the field. A draw was held, and saw 5 lucky winners, giving a fun incentive for those taking part.

International Aquafeed magazine managed to meet a number of innovative companies and individuals, who we will be sure to follow up and include exciting new editorial articles from in the following editions.

Among the many companies we met with include: AeroTube, Agranco, Aquatec Centre, AST, Deepchill, Flocell, Green Plains. Hayward, HiBlow, Innovasea, Sterner Pumps, The Andersons, Zooca, and BioFishency.

The event sponsored by National Aquaculture Association, U.S. Aquaculture Society, and Aquaculture Suppliers Association.

Overall, the event was an overwhelming success, and helped elevate trade in the industry through networking and educational opportunities.

North Atlantic Seafood Forum

At the 2023 North Atlantic Seafood Forum held in Bergen from 7 to 9 March, feed was not a blind spot, quite the contrary. The Norwegian environmental foundation, Bellona, made it clear: based on the fact that “our food system accounts for 1/3 of the climate footprint, 70 percent of fresh water use and 80 percent of deforestation, we have to ask ourselves what salmon should eat”.

Environmental impacts assessment

Never was the link between feed and food systems so evident: Biomar’s “better feed, better food” presentation highlighted the central role that feed plays in the company’s efforts to support food production while reducing carbon emissions. “It all starts with the feed” said Carlos Díaz, “97 percent of our emissions are in scope 3. The efforts we did in the past to reduce our reliance on fishmeal and fish oil have increased our feed’s carbon footprint”. The future looks to more byproducts (circular feed), single cell protein (restorative feed), low trophic species.

Sustainability is much more than carbon footprint. “We need to address ingredients with a more holistic angle. Greenhouse gases calculation is an area where we can measure across all ingredients. Cargill aims at having aquaculture farmers achieve a 30 percent reduction of their seafood carbon footprint. It’s a collaborative performance. There are only 6 crop cycles now to 2030.” Cargill‘s Dave Robb insisted.

With 94 percent of Skretting’s emissions coming from feed, supplier engagement and more primary data are instrumental: 249 suppliers make up 80 percent of our scope 3, Jorge Díaz Salinas explained.

LCA is the most accepted method to assess the range of environmental effects assignable to products and services. “LCA data will increasingly be part of formulation constraints” stated IFFO’s Brett Glencross. Therefore, IFFO has initiated a data in project based on primary data collection together with the Global Lifecycle Assessment Institute.

Based on current data available, all ingredients have sustainability tradeoffs. Across the feed sector, including all feed ingredients, there is an urgent need for standardised assessments according to the EU’s agreed PEFCR rules and for reporting the independently representative data.

Shrimp and salmon are the trade leaders in seafood according to Rabobank, with Ecuador having become the champion of shrimp exports. China’s leading seafood supplier is Ecuador followed by Russia and Vietnam. As of 2022 China has become a new net importer and Norway the first net seafood exporter, Ecuador ranking second.

Marine omega3 PUFA are core to the reputation of salmon. While it is well established that fish oil is the main source for these, supply of EPA and DHA, the essential fatty acids, has been a major concern recently, as highlighted by Nofima: “essential fatty acids in salmon diets have been diluted by vegetable oils (rapeseed mainly). New research has suggested higher requirement levels for normal physiology welfare and quality of salmon. Further dilution is not an option”.

The omega3 gap

“We are facing an omega3 crunch” said Cargill.

Fishmeal and fish oil remain key ingredients for fish nutrition, with up to one third of fish oil consisting of EPA and DHA. Fish oil supply being limited to 1.2 million mt a year, the omega3 gap needs to be closed using additional ingredients.

While Veramaris and Corbion both presented algal oil’s properties based on essential fatty acids, Nofima discussed high omega3 canola oil: a genetically modified oil that mainly contains DHA.

Market trends

IFFO presented the 2022 market trends: almost 90 percent of the total fishmeal consumed worldwide in 2021 was used by the aquaculture sector. Pet food is the fastest growing sector among the consumers of marine ingredients (i.e., around 190,000 Mt of fishmeal and 70,000 Mt of fish oil per year), although only premium dry pet food is using them.

70 percent of fish oil is used by the aquaculture sector. With an estimated annual consumption of 175,000 Mt, direct human consumption through omega-3 supplements and EPA-DHA based medicines is a growing market, up by 5 percent between 2021 and 2022.

Circularity is not new in the marine ingredients industry but is gaining momentum: 34 percent of the raw material used for reduction came from by-products in 2021.

Fishmeal 2022 production was lower compared with previous years: it ended up short of 4.8 M mt due to reduced landings in Peru. Fish oil supply on the contrary remains stable at around 1.1-1.2 million Mt.

Steady production is expected in 2023 with a rebound expected in fishmeal production.

FEED PROCESSING market outlook in Latin America and beyond

Feed milling is the process of grinding and processing feed ingredients into a form that is suitable for animal consumption. Milling is therefore a critical step in the production of animal feed, as it creates a uniform mixture that is easy for animals to digest. Various materials are milled, fed and weighed, and mixed together including additives to obtain the end product. The feed milling process can be divided into five main stages: raw material handling, grinding, mixing, cooling and pelleting.

Pellets held the biggest market share, according to a survey by Verified Market Research. The pellets market size was estimated at US$8.23 billion in 2021 and is expected to expand at a compound annual growth rate (CAGR) of 5.5 percent from 2022 to 2030.

Pellet feed is more popular than other types of feed because it is high in protein, easy to digest, and degrades the higher protein in smaller amounts. Pellet is further subdivided into crumbles, flour, mills, and others. The advantages of pelleted feed, such as improved feed consumption and increased animal weight gain, are what essentially drive the need for feed pelletising. Pellet production is increasing significantly as a result of the expanding demand for nutrient-dense feed, which also encourages company investment in the animal feed pellet processing sector. Additionally, providing mixed nutrients in every pellet, enhancing storage capacity, lowering transportation costs, and improving feed handling are some of the advantages that have encouraged the popularity of animal pellets.

There is a growing focus on the nutritional value of the food animals consume. Also, there is a growing demand for feed mills due to the following reasons: farmers stepping back, the total animal population and the increasing need for high-quality feed. Operations of the global feed processing market has been segmented into manual, semi-automatic, and automatic where technology has become a significant trend. Higher processing

capacity, more efficient processing of more products per hour, and a higher consistency of quality is strived for.

On October 3 – 5, 2023, Victam is hosting the first Victam LatAm event in São Paulo, Brazil! This event for all segments of the animal feed production is co-located with two dedicated events for flour processing and handling events, GRAPAS and GEAPS. Conferences, seminars and round table sessions are organised together with key partners (such as RTRS and Perendale among others) including topics such as feed mills maximised and sustainable production. Victam LatAm event forms a complete and unique marketplace and will fill the gap in the Latin American market.

According to the Latin America Animal Feed Market Outlook 2027 research report, Latin America is the fastest enlarging market for animal feed processing. It is estimated to grow with a compound annual growth rate (CAGR) of 3.21percent for the forecasted period. Currently, Brazil is the leader of Latin American market holding more than 40 percent in the animal feed (processing) market.

Since September, when the event was launched together with our Founding companies Andritz, CPM, Famsun, Wenger and Zheng Chang, almost 100 companies already confirmed their participation. CPM Europe is one of the world’s leading suppliers of technologies, solutions, services and industrial equipment for the animal and aqua feed industries. With over 80 years of experience in the feed industry, our extensive expertise allows us to offer specialist solutions for the processing of compound feed. This includes poultry, such as chickens and turkeys, ruminant animals such as cows, goats and sheep, as well as monogastric animals such as horses and pigs. We are pleased to have them join us on our Latin-American journey and to hear more about their feed processing approach.

Interview with CPM

What makes participating to this upcoming event in LatAm different than the other events?

Latin America is increasingly seen, by many, as the main supplier of food to many regions in the world. Latin America is one of the world's largest grain producers, led by Brazil as the world's leading soybean producer. Adding to all this, there is a very structured growth in the Pet Food sector in Latin America, projecting a CAGR of 7.6 percent for Brazil alone. This healthy economic climate is the reason why this region is so interesting to investors and offers a lot of business opportunities.

What are your expectations of Victam LatAm? What outcome do you expect?

We believe this is the right time to find customers and prospects, as well as business partners. CPM is always aiming to build long-term relationships and understand how we can better serve our customers by analysing and understanding their needs and presenting them with solutions. We believe that a good faceto-face discussion is a perfect way to do this. We expect that VICTAM LatAm will open up great business possibilities, by attracting the right audience and providing the tools for exhibitors and visitors to meet each other. In addition, we expect that VICTAM LatAm will enable us to showcase our solutions which are of the highest quality and reliability that the industry can offer.

In what way is Victam contributing to your success?

VICTAM is a well-known global event that enables visitors to discover the latest innovations and technologies and find great business opportunities. We expect VICTAM LatAm will do the same for Latin America and we look forward to meeting visitors from all Latin American countries. VICTAM LatAm visitors looking for the newest solutions in feed plants will certainly find them with CPM.

How do you incentivise sustainability?

We don’t just believe in sustainability; we make it happen. We are committed to making the world a better place for current and future generations. This is why, among other initiatives, we actively promote rework and waste recycling. When it comes to our equipment, we continuously innovate to reduce the energy consumption of our equipment.

What is the biggest challenge within the industry that you are currently facing?

There are two big challenges that the industry is currently facing:

Continuous evolving need for improved sanitary and food grade products

Higher capacity at specific recipes and granulation

What is/are CPM’s most recent milestone(s)and what distinguishes you from others?

We recently acquired Bliss Industries, a majority supplier of grinding equipment for and lead supplier of new petfood facilities in the North American petfood industry.

Some of the things that distinguish us from others are:

The process knowledge that we have accumulated by serving the animal feed and pet food industries for many years.

The focus on customer unique needs and requirements

Automation and controls for complete facility through our Beta Raven brand

Can you tell us a little bit more about your R&D processes?

We would like to invite all readers to join us at our booth so we can talk details because there is a lot to share about this topic. Just a tip of the iceberg, we have various patented technologies for equipment, processes, and parts. Also, we are expanding R&D test centers in multiple company locations around the world.

How are you coping with new trends and technologies?

Through our culture of innovation, we are constantly inventing new ways to meeting customer-specific requirement and needs.

There are a few technologies we can name that we are focussed on:

Sanitary processing, improved cleanability, operator safety, plant safety.

R&D testing for customer-specific formulations.

Using complete facility controls to shift toward automation through our Beta Raven brand

Resulting in improved reliability and operations efficiency. Blending, batching and weighing is a current trend with automation and important due to restricted diets.

How do you think that new innovations and technologies will impact the industry in 5 years?

Because we continuously aim to improve our business, we reinvent ourselves every 4-5 year. The petfood industry has evolved more toward a “human” diet and we will continue to develop healthy eating trends for pets. With the global markets continuing to domesticate animals, the demand for high-quality petfood is growing.

Thomas Kaesar, Chairman of the Board, Kaeser Kompressoren, Germany

Thomas Kaeser, born in 1953, in Coburg, Bavaria, Germany.General qualification for university entrance at Ernestinum Gymnasium in Coburg.

Following an industrial engineering course of studies at the Technical University Karlsruhe in Germany and trainee residencies in France and the US, he joined the parental company in 1979 and became Managing Partner of KAESER KOMPRESSOREN GmbH in Coburg in 1985. Since February 2012, he is the Chairman of the Board of kaeser kompressoren se.

He is also on the Board of the VDMA (Verband Deutscher Maschinen- und Anlagenbau - German Engineering Federation), the advisory board of the exhibitors of the Hanover Fair, the PNEUROP Council and the Association of the German Trade Fair Industry (AUMA). He has been awarded the State Medal for outstanding services to the Bavarian industry (in November 2012).

When you first took over as a managing partner of Kaeser compressors in 1985, what were the hurdles you had to face?

There were no hurdles to face but a lot of challenges: to understand all the demands of different customers, to foster the relationships with our suppliers, to continuously find and develop new markets e.g. aquaculture, to push innovation and new product development, to canalize financial resources efficiently and properly, to develop a worldwide supply chain and to organise efficient and flexible production. To understand all this, to network and to communicate all these departments lead to the result of a successfully growing company.

In recent years what are the most critical technological developments that you have witnessed in the sector?

Of course it is important, necessary and inevitable that all products and services need continuous development for improvement with the main goal of energy efficiency and reliability. But even in those days I have seen the necessity for computer devices inside and outside machines and activity for the digitalisation of machines (digital twins) and processes.

In 2012 you were awarded the State Medal for Outstanding Services to the Bavarian Economy. What contributions have you made to the profession that is most meaningful to you?

For more that 100 years Kaeser Kompressoren has been a continuously positively developing company engaging every year additional competent and motived people who have been offered interesting and challenging tasks and an extremely safe working place. Even in very difficult times like the finance crisis in 2009 and the COVID crisis

in 2022/2021, we did not give notice of any of our staff. Additionally, for nearly 20 years we have a programme to engage more than double as many apprentices as we needed to engage in the beginning, as to give to young people a chance of receiving good education and a precious possibility for a long-term job in the future. Last but not least, the strategy of Kaeser Kompressoren has always been to offer to our customers a solution to save energy and money which is good for the company and good for the environment.

What are Opportunities for solution innovations that support sustainable goals in current manufacturing industry?

Digitalisation is a vital goal and development of Kaeser Kompressoren and all other companies as well to remain competitive and successful and to save as much energy and resources as possible.

Kaeser compressor celebrated 100 years a few years back. How would you describe the companies journey from a small workshop in 1919?

You can imagine that a journey of more than 100 years has many bright and also some dark moments. But the trust and confidence in our own strength and in a possible good future combined with the loyalty and solidarity to and of our employees, customers and suppliers has made it possible to overcome all the difficult challenges which appeared in our history.

Where do you think the industry will be by 2050? Well, I cannot predict what future brings but we will work hard, goal-focused and with the best possible communication to employees and stakeholders. This ensures our success in the future.
