New staff at Aquafeed It’s a pleasure for me to welcome three new staff members to International Aquafeed magazine this month. All are joining our editorial team here in While it is never easy to have staff leave, we have taken the opportunity to boost our team by two additional staff. I will introduce them below and encourage you to connect with them to help us - and them - report on the important aspects of the aquafeed and fish farming sectors which we cover in our monthly magazine.
Novel ingredients in the production of shrimp diets, from a joint collaboration between Poet Nexpro, Praire AquaTech and our editor Professor Simon Davies leads the way (see page 18) followed by a feature on how organic acids and essential oils can help reduce the reliance on antibiotic use (see page 24). This has been prepared for us by Professor David Huyben of the University of Guelph in Ontario, Canada. Red yeast for rainbow trout, which highlights the best dosage to give, has been submitted by Dr Carlos Horacio Luna-Flores of the Queensland University of Technology in Australia and makes some interesting observations that will add to our sum knowledge of red yeast in aqua diets generally (see page 28). We return to more about the shrimp industry (on page 32) when we look at the changing supply of feed ingredients for this aquatic species along with some interesting figures on how global production regions are developing. Tech Update is always an interesting section of the magazine to keep a close watch on wth imany of these developments helping to enhance conditions that allow farmers to get the best return from their high-quality and expensive feedstuffs.
We report on underwater robots, a project looking into the clarity of sea water and the use of artificial intelligence and its likely impact on the way we will go about our business in aquaculture in future. We have our Technology Showcase towards the back of the magazine and follow that with a final feature on our supporting species in salmon farming - the Lumpfish (see page 48). Don’t overlook the Events Section and The Market Place which both provide connections to companies that are worth following. As we will be at the Victam-VIV co-hosted event in Bangkok from September 7-9, 2022 (at the Impact Expo Centre, Bangkok) we have invited Dr Loc Tran as our interviewee on page 64. Dr Loc Tran will be speaking as a keynote presenter alongside Professor Davies in the one-day Aquatic Asia 2022 Conference, which takes place on September 6, 2022 a day before the start of Victam-VIV event in the Amber Room at Impact from 09:00. See you there!
What is particularly advantageous about employing younger graduates is that they have been fully immersed in computer and digital technology, have excellent writing abilities and enquiring minds. While aquaculture and aquatic feeds in particular are specialist areas of employment, a journalist team such as ours is what connects specialists and technical developments in our industry to those who need to know and understand what is happening. Our team is led by Professor Simon Davies and Erik Hampel. Our editorial team – and that includes three long-standing editorial team members as well - is fit for purpose and is here to drive forward our magazine content which is in its 32nd year. In fact, we have just produced our 2023 Media File that is now available via our download link - https://aqfeed. info/e/1529.Finally,Iwould like to draw your attention to the QR code below.

There’s not only exciting news reports in this edition of International Aquafeed magazine - namely, the historic development of aquaculture in the Oman and the awarding of ISO45001 to Biomar, plus a report from the Dublin Innovation Studio, etc - but a range of features that will be of interest to all our readers.
We found very solid evidence that up to 30 percent inclusion of this product was feasible and with benefits to the ultra-structural morphological integrity of the intestinal absorptive surface.
The scientific based meeting will encompass several local speakers and our combined theme will be the circular bioeconomy and how we can address this important issue in relation to aquafeeds. This will be relevant for both shrimp and fish nutrition and their health status. My topic examines the potential value of advanced high protein distiller’s dried grains & solubles HP-DDGS for fish with an example of previous research work involving tilapia and with my Kurdish colleagues.
However, there is now a rapidly expanding biofuel industry that is pertaining to the green agenda to produce ethanol from sustainable and renewable sources. These are all based on the fermentation of grain notably corn in the USA and wheat in Europe and other parts of the world.

Turning to other matters, it is no good having great feed formulations and commercial diets for fish if we do not have a sufficient stock of juveniles to on grow. It is imperative for a sustainable and viable aquaculture industry to be able to produce fry regularly from brood stock fish.

We are at a time when major late summer and autumn conferences are back on the agenda. On that note, I am very pleased to be going to Bangkok again next month (first week in September) where I am helping to organise and attend Aquatic Asia and presenting a short address in person. This is an interesting meeting and also trade show highlighting much of the animal feed industry and also health related products.
We have discussed here many times the benefits and attributes of different classes of functional ingredients as either major components of feed or usually as supplements and feed additives. These have included various probiotics and prebiotics as well as an array of bioactive phytobiotics derived naturally from plant sources.
Professor Simon Davies Nutrition Editor, International Aquafeed - International Aquafeed
I am often impressed by the quality of the literature and the display stands with plenty of information and technical pamphlets to gather. It is a different world and scale compared to many European venues and I am sure there will be plenty of innovations and examples of enterprise and ingenuity to hand.
Fortunately, this was all correct in our online version for July so I will direct your attention to this electronic format for a total article experience via this link: https://aqfeed.info/e/1513
In our current issue you will find timely work on the use of
NexPro™ in diets for shrimp from research presented by myself and colleagues from POET Nutrition Group in Sioux Falls, USA. NexPro™ is a distiller’s advanced high protein DDG derived product with proven capacity to provide digestible protein and energy to trout, salmon, and shrimp as we have reported in International Aquafeed previously.Ihopeto report to you in our October edition the news of the venue and trade show in Bangkok, Thailand, and recent developments in the aquafeed and fish/shrimp health sector for Asia and beyond.
Please enjoy our autumn edition and keep your news and article contributions flowing.
Of course, DDGS is a by-product of distillation such as in the manufacture of whisky and beer.
Again, I am working on another snakehead species in Thailand with my colleague Dr Noratat Prachom. The aim of this was to evaluate cricket meal as a source of protein using bioconversion of organic waste streams to produce this excellent protein product. Our results showed clearly great potential for this other type of insect meal in fish feed formulations for carnivorous tropical fish culture.Inthis issue we have much more news items and technical reports, articles, and features. One notable thing is that our magazine is very complex in its monthly output. Sometimes, we like many others in the media have our technical slip-ups.
Recently, I co-authored a review paper on the use of herbs in aquaculture with my Iranian colleague Dr Sayed Hoseinifar. Asia will be very much in my mind due to the large number of participating companies and especially China that produce so many products (many herbals based) with claims to provide improved digestion, yield active enzyme sources, immunostimulant properties, offer gut integrity support and microbial (gut microbiota) balancing agents etc.
In the last month, July 2022 edition, we reported on how silicic acid can modulate specific and important genes for L. Vanammei production. The printed magazine regrettably failed to include tables and legends in the production phase. These things can happen but do so very rarely, so please do accept our apologies
I have been recently working with colleagues in Lahore, Pakistan where I co-supervise Sadia Nazir for her PhD on the production of snakehead fish with my esteemed friend Dr Noor Khan. Using artificial hormonal injection, I am pleased to announce that we have successfully spawned these fish, and this will allow hopefully an opportunity to expand snakehead production in Pakistan. It is a lucrative industry as it is a very valuable and tasty fish fetching high local prices. Our paper was accepted and is now online in the Journal of the World Aquaculture Society (JWAS).
At the recent Seafood Expo Global conference in Barcelona, FAO Aquaculture specialist Christine Rolin called for increased innovation in the seaweed industry. She reminded the audience that production is huge – about 30 million tonnes globally – but that almost all (97%) is done in Asia. Western countries have not paid much attention to the seaweed sector.
There are several good reasons to promote the exploitation of seaweed. It is a low-cost production that requires very little input. It has low environmental impact and it is at a low trophic level and produces several benefits to its surrounding ecosystem. Today’s products based on seaweed as a raw material are several, but could there be more? Could we be able to use seaweed on a grand scale in the production of fish and crustaceans? Of course, we can also eat seaweed products, but we are really more interested in the animal protein that we can grow in aquaculture.
Both of these events have resulted in very serious challenges to the world economy. We now experience exploding energy costs, accelerating inflation, and major disruptions in trade patterns and supply chains. So far, most of us have focused on the negative aspects of this development. We complain about higher costs of everything, and about the deterioration of international cooperation. The world has taken a few steps back and is opting for confrontation rather than cooperation. But at such times, I ask myself: what good can come out of this development? We have to take a positive attitude and look for the opportunities rather than the challenges. In the field of fish farming, we have for a long time been working on the development of alternative feeds, or rather alternative raw materials for fish feed. The producers have moved away from the initial dependence on fish meal and fish oil. Vegetable sources have come into focus and are being used to a greater and greater extent. But the time has now come to look at even more alternative sources of raw materials. For there is no doubt that the world will need to achieve growth in fish farming. In the wake of the Ukraine war, it has become evident that the whole world is extremely vulnerable to changes that can rapidly lead to a global food crisis. Cost is a central consideration when looking at new raw material sources. Over the past six months or so, fishmeal prices have skyrocketed. And soymeal prices have risen even more. These price increases naturally have to be passed on down the line and will eventually reach the consumer. In addition, the cost of transportation has risen, too. So, it is now desirable to avoid transporting goods and materials over long distances. How can we reduce the impact of rising prices?
As usual, we must turn to research and will rely on a massively increased effort to find new solutions through research. And the time for stepping up research is now. Or rather, it was yesterday. We need to allocate loads of money to undertake more research in all fields. Much of this research will not lead to anything in terms of results, but it will still be needed. What I propose is rather a ‘shotgun approach.’ We need to pursue all possible and impossible ideas. I know it will be costly. But can we afford not to pay that price?
A call for increased innovation
At least the majority of people are, in spite of the growing interest in vegetarian and vegan food. We need innovation in this field. And we need it now. So, the time to initiate new research that can lead to innovation is now!

We are living in pretty turbulent times. Two major events have changed the world dramatically over the past couple of years. First, we got the Covid-19 pandemic (which is by no means over quite yet), and then Russia invaded Ukraine.
Many have pointed out that seaweed represents a grossly underutilised resource. It is strange indeed that we have not paid more attention to seaweed as a possible source of raw material on a grand scale.
I am no scientist, but it appears to me that we need to study the properties of seaweeds, all kinds of aquatic plants in fact, to see if we can find some solutions.

Red yeast for rainbow trout: Which dosage gives the best results?
Andfjord Salmon, Skretting and Zooca have signed an agreement to facilitate the provision of a specifically designed salmon feed for Andfjord Salmon as well as a long-term cooperation to increase incorporating zooplankton Calanus finmarchius in salmon feed. Calanus Plus, by Andfjord Salmon, marks the first salmon feed that uses the zooplankton Calanus finmarchius as a raw material ingredient. It also contains algae oil as an alternative to fish oil.
“Calanus finmarchius is nature’s own ‘starter’ feed. It is a natural prey that is biologically adapted to provide optimal nutrition for fish. Adding Zooca Hydrolysate will be very useful to stimulate the fish’s appetite in the transition to seawater,” explains Mads Martinsen, Director of Product Development and Sustainability at Skretting. Andfjord will be the first salmon farmer in the world to use a commercially developed feed with Calanus. Earlier in February, Andfjord entered into a feed supply agreement withTheSkretting.agreement has overseen the development of a feed tailored to the company’s flow-through technology which ensures optimal water quality, fish welfare and growth conditions.
The zooplankton is one of the most abundant animal species on the planet with a reproduction of 300 million tonnes. It is Norway’s largest harvestable and renewable marine resource. Current rates show that Zooca only harvests 0.0005 percent of total volume per annum.
Martin Rasmussen, CEO of Andfjord Salmon who was involved in releasing the first smolt, refers to “ambition” with mention of the feed. “Our ambition is to develop the world’s most fish friendly and sustainable aquaculture facility of its kind. Having our own specially designed feed, with unique ingredients from a local supplier, is another important building block towards realising this ambition.”
“The fish has settled quickly and has already demonstrated a healthy appetite, which continues to improve daily. Fish mortality rate is extremely low, so it has been a promising start,” Mr Rasmussen adds.
Zooca is responsible for supplying the Zooca Hydrolysate to Skretting, which processes Calanus finmarchius at its facility at Sortland, nearby to Andfjord’s site at Kvalnes. The company has, for the last 20 years, researched and developed technology that can sustainably harvest and process the zooplankton.
“By sustainably harnessing high-performing, high-quality nutrients from Calanus finmarchicus, there is a large potential to improve long-term human health and ensure superior animal nutrition around the globe.
“We are delighted to secure this commercial breakthrough within salmon feed together with Andfjord Salmon and Skretting,” says Hogne Abrahamsen, International Account Director at Zooca.
“We look forward to using Calanus Plus by Andfjord Salmon at our Kvalnes site and to the long-term cooperation with Skretting and Zooca,” concludes Martin Rasmussen.
Andfjord recently released the first smolt into its site at Kvalnes at the end of June this year, reporting that smolt had adapted quickly and biological conditions were as expected. The site utilises flow through technology which enables the producer to simulate wild salmon’s natural habitat in a land-based facility.

This month on IAF TV Look out for this development for the North African market from September 2022: Nabil Hamid, the chairman of Grand Fish Feed in Egypt, exhibited his company's range of feed products during the delayed Aquaculture Africa event AFRAQ 2021 in Alexandria, Egypt (at the end of March 2022). Speaking to Roger Gilbert, the publisher of International Aquafeed magazine about the success of his company within the aquaculture sector both in Egypt and across the North African region. He spoke about the development of a new production facility that will come online in September 2022. Watch more videos at: www.aquafeed.co.uk/videos aqfeed.info/e/1528 Scan to watch the video for FREE - International Aquafeed
Over the past 25 years he has worked in various academic, institutional, and industrial roles across Australasia, the Middle East and Europe. McKuin, BL, et al. 2022. Comparative life cycle assessment of heterotrophic microalgae Schizochytrium and fish oil in sustainable aquaculture feeds. Elem Sci Anth, 10: 1. DOI: https://doi.org/10.1525/elementa.2021.00098
So, clearly this would suggest that head-to-head fish oil is a more sustainable product when considered objectively. Maybe that’s the critical take-home message here?
In addition to this, the authors compared the production of Schizochytrium in two geographic regions (Brazil and the USA) and as either two different products, one as a dried whole-cell product and the other as an extracted oil. Even different oil extraction methods were considered. Most likely this was done to reflect the main commercial production of such products in the global marketplace. And importantly, the allocation elements were done on an economic basis making the work directly relevant to the accepted norms for the feed sector as based on the product environmental footprint categorization riles (PEFCR) from the European Union. Overall, I thought it was an excellent and comprehensive piece of work.
One of the qualms we often see around fish oils is their perceived lack of sustainability, with many of the alternative products being touted as being more ‘sustainable.’ So, I was intrigued recently to read a new paper by McKuin et al (2022) who reported a comparative lifecycle assessment (LCA) approach for a suite of different microalgal (Schizochytrium) products against each other and against fish oil.
The great thing about using such an LCA approach to assessing the sustainability of an ingredient, from my perspective at least, is that it provides a clear point of objectivity about the process. So, there is less rhetoric, and more clarity in the claims being made about what one means when we use words like sustainable.
Measuring the ‘footprint’ of oils
What is also worth noting at this point that a simple review of global warming potential (GWP; a.k.a. carbon footprint) data from the Global Feed Lifecycle Assessment Institute (GFLI) database, shows that fish oil in its own right can have quite a variable carbon footprint with more than a 100 percent difference between the highest and lowest estimates, but that the carbon footprint of canola oil is about three times greater still than that of the average fish oil value (Figure 1).
So, if canola oil is being added and respectively diminishes the absolute carbon-footprint of Schizochytrium oil, then the footprint of the product neat must clearly be something considerably larger. Despite this complication of the canola oil dilution, the authors still clearly mentioned that fish oil had “significantly lower impacts across environmental indicators.”
The study alsoidentified that one of the biggest drivers of the ‘carbon footprint’ for these Schizochytrium oils, was the need for input of sugar (sucrose) as a carbon source for driving the production of these heterotrophic organisms.
Or even as a simple mass-basis for each product, so any formulator can readily see the overall contributions based on how the different products might be applied to a feed formulation.

Brett Glencross
But what struck me as odd was that the authors presented the comparative data against fish oil based on the Schizochytrium oils being diluted with canola (rapeseed) oil. It was indicated that this was done to provide a DHA (22:6n-3) parity basis across products, though perhaps more relevant would have been to provide that parity on a total long-chain omega-3, basis as that is the basis by which such oils are traded.
Dr Brett Glencross is the Technical Director of IFFO - The Marine Ingredients Organisation.
The study by McKuin et al (2022) proved to be a useful examination of the various inputs and processes from ‘cradle to factory-gate’ of producing different Schizochytrium products and their impacts on the various LCA parameters.
“The arrival of Norcod is extremely important for Nesna and as mayor I am delighted it has been given the go-ahead to begin cod farming in our community,” adds Hanne Davidsen, the mayor of Nesna municipality.
Listed Norwegian cod-farming venture has been granted permission to establish a new production location in the Norwegian municipality of Nesna, with a total maximum allowed biomass (MAB) of 3600 metric tonnes.
“Our ambition is to contribute not only to the industrial base of the coastal municipalities in which we are active, but also to support employment opportunities and ensure sustainable operations with minimal impact to the environment,” he adds.
The new site will be equipped with state-of-theart aquaculture technology and is planned to go into production in the first half of 2023. “Setting up a new location is always an exciting process especially given our motivation to provide a healthy source of protein to an eager market. We have a highly skilled production team with many years of combined experience so I anticipate this will be a smooth and efficient process,” continues Mr Riber.Good community relations are also integral to Norcod's strong commitment to responsible farming of premium product.
“We have been very well received by Nesna municipality, which we highly appreciate, and we look forward to continuing our excellent cooperation. We consider the site at Labukta to be perfectly suited for cod farming with good water depth, water temperature and current conditions. I am confident our fish will thrive here,' says Christian Riber, Norcod CEO.

“We wish them the best of luck and trust that we will continue to work together successfully in future.”
Including Labukta, Norcod now has a total of five codfarming sites along the Norwegian coast encompassing 19 licences with MAB of 13,920 metric tonnes in total. The company recently finalised its first full production cycle and is set to begin harvesting its second cycle in the third quarter of this year. It is also in the process of putting its third cycle of cod into the sea phase this summer.
Fostering aquaculture discipline
During a panel discussion with Teresa Morrissey, Irish Farmers Association (IFA) Aquaculture, Carsten Krome, Founder & Partner, Hatch, Martin Dempsey, Founder and CEO, Sealac Ltd and Richard Donnelly, Shellfish and Salmon Manager, BIM, Richard Donnelly drew parallels with the IFSC's ability to spur investment and innovation following its established three decades earlier.
“It is just 35 years since the IFSC was established. It is remarkable to consider how its establishment was truly visionary at the time, and how many other sectors followed in its path. The aquatech sector in Ireland has the potential to achieve this same effect.”
Aquamontrix, a continuous real-time sensor technology to monitor nitrate and nitrite levels in sea water.
The event, now in its fifth year, is the culmination of a month-long Innovation Studio where ten business start-ups from different disciplines took part in an intensive programme to help fast-track their business ideas for commercial viability in the Irish and global aquaculture industry.
Wayne Murphy, Co-founder and Managing Partner at Hatch, refers to the risk-taking intrinsic to entrepreneurship and central to the continued innovation and growth within aquatech in Ireland and globally. He also references the initial approach Hatch made some five years earlier with BIM and how the State seafood development agency had been supportive from the outset.

Giving the opening address at the event, BIM CEO Jim O'Toole spoke about food security and the long-term strategy to develop and foster local aquaculture talent. This involves attracting other crucial disciplines like engineering, analytics and finance to help them develop Irish aquaculture businesses with a global reach.
“Investing in aquatech is specifically targeted in the Government's Food Vision 2030 strategy and is something BIM is intent on delivering. Our ambition is to position Ireland as a global centre for aquaculture innovation and to support companies to grow and develop in this sector in collaboration with other agencies.”
The global aquaculture industry is the fastest growing food sector today. Its value exceeds EUR€280 billion. The Irish aquaculture industry is currently valued at EUR€175 million with primary production (fin-fish and shellfish farming) at its core.
To date 46 start-ups have participated from BIM's Innovation Studio, supported by the European Maritime, Fisheries and Aquaculture Fund and run in partnership with global aquaculture accelerator Hatch. The initiative has seen more than EUR€13 million (EUR€1 ~ US$1.01) invested and 130+ new jobs generated in aquatech in Ireland.LeeHunter, a young Donegal oyster farmer was among the start-ups taking part in this year's programme. His business, The Oyster Pitch, uses sound technology to monitor oyster welfare and to reduce mortality.

An eight-week growth trial was conducted to evaluate the use of corn fermented protein, NexPro, in combination with soy fermented protein, ME-PRO, on the performance of juvenile Pacific Whiteleg shrimp, Litopenaeus vannamei. The experimental design used two inclusions (9 and 18%) to replace conventional marine and land animal protein (LAP) ingredients.
Though not statistically significant, this study indicated that test ingredients numerically improved shrimp growth performance at higher inclusions (18%) in the diet.
Novel ingredients in Litopenaeus vannamei diets
A basal diet (33% crude protein, 8% lipid) consisting primarily of animal proteins (fish, poultry, and squid meals), soybean meal (SBM), and wheat flour was used as a control. The test diets were produced by replacing appropriate amounts of animal protein and SBM with NexPro at 9% and 18% inclusions.
Processed Animal Proteins (PAPs) or Land Animal Proteins (LAP) is also viable but not always feasible in some regions of the world due to cost and quality issues. There is now a strategic effort to evaluate novel ingredients for species of fish and shrimp in accordance with meeting the ‘protein and energy’ gap in aquafeed formulations. Further issues have centred on the escalating price of conventional raw materials particularly grains such as corn and wheat resulting in the fluctuation of the commodities and futures markets.Dueto the recent price rises of the fossil fuel (oil, gas, and coal) market we are observing a rapid growth in the biofuels sector and a need to exploit the resulting by-products generated. This is now being achieved by enhancing their nutritional value and especially
Introduction Shrimp is a major sector of the aquaculture industry and very lucrative in the global market. The shrimp industry was valued at US$39.24 billion in 2019 which is expected to attain US$54.6 billion by 2027, with a CAGR of 9.2 percent from 2022 to 2027 (Mordor Intelligence Report (2022).
Three diets were randomly assigned to six replicate groups of 40 shrimp stocked in 0.15m3 culture tanks. The eight-week trial revealed that the growth performances of the two test diets were not significantly different from the control diet containing higher amounts of marine and land animal proteins.
An assessment of the performance of POET NexPro and ME-PRO® in practical diets for Pacific Whiteleg shrimp by Professor Simon J Davies FRSB, Editor, International Aquafeed, UK; Derek Balk, Melissa Jolly-Breithaupt, PhD and Kevin Herrick, PhD, POET Bioproducts; Brandon White and Luke Fredrickson, Prairie AquaTech, USA Left - Figure 1: Test diets produced using single screw extruder (1.8mm sinking pellet) Right - Figure 2: Feeds after soaking in water for 20 minutes. - International Aquafeed
In accordance with efficient production, it is imperative to drive towards increasing sustainability and this includes emphasis on feed sourcing and meeting targets to reduce further traditional raw material dependency especially primary marine ingredients and soybean that is the subject of much concern due to finite availability and environmental implications. In this context, Kok et al 2020 examined the fish in to fish out ratio for different species including shrimp. Malcorps et al (2019) highlighted in their work the sustainability dilemma of dependency on soybean in diets for shrimp at the expense of fishmeal and other ingredients.
Dry distillers’ grains plus sollubles (DDGS) cost provides formulators the ability to lower their dependence on marine or LAP ingredients, which will lower feed costs without sacrificing performance. The use of ethanol production coproducts can help produce diets for aquaculture that are less expensive. Finding complementary ingredient combinations will allow formulators the ability to supplement or replace marine and LAP sources. Fish meal typically has a protein content between 65-70%, which makes its replacement with lower protein ingredients difficult. This initial trial served as a foundation for evaluating the combination of NexPro with ME-PRO at two inclusion levels at the expense of fishmeal, soybean, and poultry by-product meal. The 52% protein concentration of NexPro, combined with 70% protein ME-PRO provides a competitive blend that is comparable to fish meal on a per-unit protein basis. Previous work reported by Davies et al. (2021) on L. vannamei focused on NexPro, testing incremental inclusion levels with excellent performance. It was found that NexPro could be included without compromise on growth and feed efficiency performance up to 1820% and significantly reduce soybean and fishmeal components of the diet. Investigations by Guo et al, (2019) and Novriadi et al. (2021) further validated the use of NexPro in diets for L. vannamei showing excellent results. The purpose of this new study was to report the growth performance of shrimp fed a value-added experimental ingredient, NexPro, in combination with ME-PRO as their respective nutritional profiles are complimentary and deemed ideal for use in feed formulations of several species of fish and shrimp.

The diets were then bagged and stored at room temperature until use. Each diet was assigned a code and feeding occurred on a blind basis. The feeds were further analysed for their physical characteristics.Eachfeedwas placed into water for 20-minute periods before removal (Figure 2). The nutrient leaching and pellet stability
All diets were formulated using a commercial feed formulation software. All feeds were manufactured using identical commercial extrusion methods at Prairie AquaTech (Brookings, SD). Dry ingredients were ground using a Fitzpatrick Comminutor (Elmhurst, IL) equipped with a 0.65mm screen prior to blending. Complete ingredient mixes were then transferred to a ribbon mixer (Patterson Equipment, Toronto, ON) and blended for five minutes. The homogenous feedstuff was then extruded using an ExtruTech E325 single-screw extruder (Sabetha, KS) equipped with a 1.5mm drilled die plate that produced 1.8mm diameter sinking pellets (Figure 1). Extruded pellets were dried with a conveyor oven drier (Colorado Mill Equipment, Canon City, CO), screen sifted with a Rotex screener (Rotex Inc, Cincinnati, OH) and then lipid coated using a Phlauer vacuum coater (A&J Mixing, Oakville, Ontario).
for monogastric animals including fish and shrimp. Distiller’s grains are a nutrient-rich co-product of the bioethanol process. NexPro® is a next-generation protein ingredient derived from the dry-mill bioethanol production process. As a 50 percent protein product, NexPro protein ingredient is a suitable choice for aquatic animal feeds. ME-PRO, produced using a unique fermentation process to reduce potential anti-nutritional factors and enhance digestibility, is a new alternative protein obtained from high-quality soybeans (Bae et al, 2020).
Calculations for relative growth (RG) and specific growth rate (SGR) were determined using the initial and final average weight per shrimp. Individual tank feed containers were weighed to determine feed conversion ratios (FCR).
On day 0 of the trial, forty shrimp were stocked into each tank of the recirculating system. Initial tank biomass (Day 0) for the 18 tanks averaged 37.84 ± 3.66 grams per tank (0.25 ± 0.02kg m-3).Shrimp were fed to satiation three times per day for eight weeks. Satiation was determined when a small amount of feed remained in each tank. Tank biomass and average weight per shrimp were determined by group weighing the forty shrimp together.
Upon completion of the eight-week feeding trial, shrimp were counted, and group weighed together to determine tank biomass and average weight per shrimp. These measurements were used to calculate weight gain, specific growth rate and survival.
Water quality was stable and within the desirable range for L. vannamei shrimp (Table 3). Water parameters did not significantly fluctuate during the trial nor did they significantly

The recirculating aquaculture system (RAS) that was utilised for this trial consisted of eighteen, 40 gallon tanks. Each treatment was randomly assigned to six replicate tanks. The RAS was equipped with mechanical and biological filtration, UV sterilisers, pure oxygen injection, and a heat pump. The saltwater temperature was maintained at 31°C, and all water parameters (Table 3) were maintained at optimum levels for culture. Dissolved oxygen, water temperature, pH, and salinity were measured daily using a YSI Proplus multiparameter instrument (YSI, Ohio). Total ammonia nitrogen, nitrite, and nitrate were measured weekly using Hach TNTplus reagents and a DR3900 Spectrophotometer (Loveland, CO). Saltwater was prepared using marine salt (Crystal Sea, USA). The salinity for the duration of the eight-week trial was maintained at 20.16 ± 0.77 ppt.
Diets were formulated to be isonitrogenous (33% crude protein) and isolipidic (8% crude fat). The control diet included standard levels of menhaden fishmeal (6%), squid meal (3%) and poultry meal (4%). Test diet composition of the primary protein ingredients is listed below in table 2.

for each diet was very similar. Based on these results, we are confident that nutrient leaching did not influence the performance of the Chemicalfeeds.composition (proximate analysis) of feeds was analysed using third party laboratories (Midwest Laboratories, Omaha, NE). Proximate composition of samples was determined following the Association of Official Analytical Chemists (AOAC 2005). The as fed proximate composition of test diets is presented in Table 1.
Post larvae shrimp were obtained in October of 2021, from American Mariculture (Florida). Prior to the start of the trial, shrimp were all fed the same holding diet until they reached an average size of approximately one gram.
Statistical analysis
Water quality parameters (temperature, DO, pH, nitrite, and alkalinity) and growth rates of shrimp were analysed by one-way analysis of variance (ANOVA), using SAS Program Version 9.4 (SAS Institute, USA) followed by pairwise comparisons by Tukey’s test for significance.

The 18% inclusion of NexPro showed numerically higher growth rates and lower FCR when compared to the 9% inclusion diet. The diets prepared for this experiment were determined to be well accepted by the shrimp with almost no uneaten feed remaining in the tanks 30 min to 1 hour post-feeding. The survival percentage of each tank at the end of the feeding trial was normal and feed treatments did not influence survival (TableBased4).on SGR and FCR, NexPro showed a positive trend in terms of increasing inclusion levels (Figures 4 and 5). Overall, shrimp fed the diet containing 18% NexPro displayed the best growth performance among experimental diets producing the highest average weight (Figure 3) and biomass density of shrimp at the end of the trial (Figure 4).
Other plant-based ingredients such as soybean meal have variable levels of ANFs that can actively interfere in digestion and nutrient assimilation. Developing ingredient combinations that work well together to produce a highly palatable and digestible pellet will encourage formulators to incorporate other ingredients as their staple proteins.
Discussion To date, the aquafeed industry employs a wide range of ingredients to varying degree for shrimp diets and specific ingredients dominate such as fishmeal and soybean meal. This investigation addresses a growing opportunity to incorporate advances in DDG technology to provide a novel and sustainable ingredient source high in protein and energy. The use of value-added DDGS as a feed ingredient will act as an effective alternative ingredient to soybean and also offset the use of animal proteins. The experimental ingredients used in this study have higher protein and lower fiber levels compared to conventional DDGS and are also void of major anti-nutritional factors (ANF’s).
Work by Goda et al. (2020) provides evidence that supplementing an exogenous enzyme like phytase can improve phosphorous digestibility and availability in diets containing high protein distillers dried grain fed to European sea bass, Dicentrarchus labrax. Similar studies should be extended to shrimp to explore enhanced nutrient utilization and efficiency of corn fermented protein.
More research is needed to fully understand the optimal inclusions and combinations of NexPro and ME-PRO in a range of diets suitable for shrimp. This would provide more detailed knowledge of digestibility and comprehensive evaluation of the health status of the gut and hepatopancreas tissues.
It has been suggested that the yeast fraction in such ingredients may confer functionality properties such an immune stimulation as well as potential prebiotic and probiotic attributes. It will also be important to conduct palatability trials and taste evaluation studies to determine consumer acceptance of shrimp raised on higher levels of DDGs. Such work will allow more refinement and extend our knowledge base to provide a safe and high efficacy product to meet the requirements of the shrimp feed sector. Linear leastcost formulation approaches may be used to explore cost-benefit analyses of novel ingredient combinations in diets fed to shrimp in various production phases and culture conditions.

How ingredients interact with each other in a feed formulation is critical to nutrition research and feed development for any species in aquaculture production systems. In evaluating ingredients for use in shrimp feeds, there are several important aspects (e.g., growth, digestibility, palatability) that must be understood to enable their use as an ingredient in feed formulations.
Though not significant, results indicate that increasing inclusions of NexPro provide improved FCR and growth rates in shrimp fed balanced formulations. This study presents similar results compared to those reported by Qiu et al. (2017) also working with Pacific Whiteleg shrimp. However, it is important to note that all test diets performed well in comparison to the control. While the diet containing 18% NexPro showed slightly better FCR than all other diets, this is likely due to an increase in the diet’s digestibility.
Feed conversion ratio (FCR), specific growth rate (SGR), and relative growth (RG) of shrimp at final weigh point in the trial are presented in Table 4. The results obtained showed no significant differences (P>0.05) among shrimp fed the control diet (FCR = 2.04) and others fed diets containing different levels of NexPro.
differ among treatment groups. Data showed that pH in tanks averaged 8.03 and total ammonia nitrogen (TAN) ranged between 0.13 and 0.61 mg/L throughout the experimental period. Both low levels of pH and TAN reflect a low level of the harmful unionised ammonia.
Recommendations
A more synergistic use of ingredient substitutions offers a more complementary blend of essential amino acids (EAAs) reducing individual EAA deficiencies. In the present study, the essential amino acids lysine and methionine were both supplemented at the inclusion levels tested. This study showed that experimental diets with a 50% reduction of LAP (poultry meal) and 61% reduction of marine protein (fish & squid meal) replaced with NexPro in combination with MEPRO can produce similar or slightly improved growth and feed efficiencies compared to the control. Research has been done using enhanced DDGS ingredients as a partial replacement of soybean meal (Rhodes et al, 2015).
Previous research has shown that ME-PRO inclusion up to 70 percent can significantly improve growth, digestibility, and survival of shrimp when decreasing fish meal in diets (White et al, 2020). Supplementing diets with exogenous enzymes may further provide supporting evidence of the performance and feasibility of diets containing next-generation protein ingredients such as NexPro and ME-PRO.

Our recent research on the gut health effects of feeding a mixture of organic acids and essential oils to rainbow trout shows promising results. Feeding a microencapsulated blend of organic acids and essential oils improves gut health and may serve as a part of an effective strategy to reduce antibiotic use in aquaculture.
Organic acids & essential oils (OA+EO) Organic acids are short-chain compounds that are mainly used to alter the pH and preserve grains during storage. Essential oils are a complex mixture of volatile compounds extracted from plant raw materials, including thyme and cloves. Both supplements are increasingly used in livestock feeds to improve gut health and disease resistance, although not much is known on their impacts on fish. Also, the combined use of both organic acids and essential oils (OA+EO) has not been studied and may produce synergistic effects.

The aim of our research, conducted in collaboration with Jefo Nutrition Inc., was to use a combination of traditional and advanced analytical methods to determine if these functional feed additives could improve the gut structure and microbiome of fish. More details on these new methods and our research below.
Restrictions on antibiotic use means the industry needs new mitigation strategies to improve the health and disease resistance of farmed fish.
OA+EO improve gut function
technique was developed in order to protect the blend of OA+EO, as well as release it into the targeted area of the intestine. Increased research into these compounds paired with this microencapsulation technique has allowed further testing in animal feeds, including aquaculture. New tech advances access to the gut microbiome Reduced costs and recent advancements in DNA sequencing technologies has allowed everyday scientists to identify billions of microbes in and around their bodies, as well as in animals. The community of bacteria along the gastro-intestinal tract of animals is referred to as the gut microbiome. The gut microbiome has been recognised as an additional organ in the body due to its ability to ferment fibre into essential fats and vitamins, interactions with our immune system and even connections with the brain and our behaviour.
Previous methods used media that was only able to grow a small number of living bacteria, whereas next-generation sequencing and bioinformatics can amplify and identify billions of bacteria - living or dead. We can now test for both large and small changes in bacterial communities in the gut and downstream effects on the growth and health of individuals, including fish.

OA+EO reduce pathogens in the gut Working with the Animal Health Laboratory at the University of Guelph, my research team found that cultured bacteria levels and diversity of sequenced bacteria did not change, but specific species of bacteria were associated with each diet. Aeromonas hydrophila and Acinetobacter species were found to decrease when fish were fed the OA+EO treatment diet. These bacteria are known pathogens that cause severe mortalities on fish farms. It seems feeding OA+EO could target these species and improve fish health and production. Using OA+EO feed supplements to target pathogens may become essential in the future due to increasing resistance of Aeromonas and Acinetobacter pathogens to antibiotics and their restricted use in aquaculture operations.

Professor John Lumsden and Dr Phuc Pham from University of Guelph performed inflammation scoring and morphometrics on the proximal and distal intestine. They found that no inflammation was present and villi length (wall of small intestine) was increased in fish fed the OA+EO treatment diet, compared to the control diet. Extended villi length and the absence of inflammation in the intestine suggest improved gut health and may lead to improved oxidative capacity and gut function.
An effective supplement for pigmentation in aquaculture is astaxanthin (AX), often supplied in the form of industrially synthesised AX. However, due to its health and safety issues, unsustainable and environmentally aggressive production process, the use of this version of AX is under review. The aquaculture industry has access to natural AX in the form of red yeast Phaffia rhodozyma (P. rhodozyma). This yeast is a member of Cryptococcaceae and is not only a great source of natural AX, it also contains an appreciable amount of protein and fat. Earlier research has shown the benefits of P. rhodozyma as a natural colorant has positive effects on antioxidant status and performance in a range of aquaculture species. However, data associated with the optimum red yeast dosage to get the highest results are limited. Different dosages tested
Aiming for maximum fish filet quality starts with a healthy fish diet that contains all the nutrients needed for optimum health andAdditionalgrowth. feed ingredients (feed additives) can be used to further improve their antioxidant status and immunity to help them better cope with pathogen challenges. Certain feed additives are also used for pigmentation, which enhances the characteristic redness and attractiveness of the filet, as well as the quality. What if there is one feed ingredient that can do it all?
Benefits of red yeast
Red yeast for rainbow trout
There is a certain expectation when consumers buy fish. It should be fresh, have a firm structure and an appealing colour.
A new study, performed by an international research team from Iran, Australia and Italy, aimed to evaluate different dosages of P. rhodozyma with an AX level of 1.6mg/g product on growth and nutritional performances, antioxidant activity, chemical composition of flesh fish and pigmentation of filet in rainbow trout weighing 208–212 grams for eight weeks at 11 degrees Celsius.Thered yeast used in the trial comes in powder form, produced by Bioproton Pty Ltd, Australia. The performances were compared with a basal diet and synthetic AX at the recommended dosage. The diets in the trial were as follows:
- Control (basal diet, no AX) - P1 (red yeast at 15.5 gr/kg diet = 24.80 mg AX/kg diet) - P2 (red yeast at 37.3 gr/kg diet = 59.68 mg AX/kg diet) - P3 (red yeast at 47 gr/kg diet = 75.2 mg AX/kg diet) - Synthetic AX (50mg AX/kg diet)
The use of natural astaxanthin as a nutritional supplement has been rapidly growing in aquaculture and is key for pigmentation, growth, immunity and fish filet quality. However, fish producers may face difficulty determining the optimal dose rate. New data from rainbow trout trials provide the answers. by Dr Carlos Horacio Luna-Flores, Advanced Industry Fellow, Queensland University of Technology, Australia
28 | August 2022 - International Aquafeed
Which dosage gives the best results?
Although AX is primarily used for pigmentation, adding red yeast to the fish diet has a range of other performance benefits, as shown in earlier studies. This trial confirms the positive effects on performance parameters when adding AX to rainbow trout diets.
Figure 1 - Specific Growth Rate (%/day) for the different treatments.
Growth performance
An increase in P. rhodozyma concentration in the diet, improved weight gain and specific growth rate alongside. A significant difference was seen among the treatments, but only the P3 diet demonstrated a significantly better growth than the group that received the synthetic AX diet (Figure 1).FCR was reduced by an increase in the level of P.

A strong immune system and high antioxidant status are key for producing healthy and high performing Rainbow trout, which helps prevent illness from pathogens or toxins. Pathogen invasion or other environmental stress factors can lead to oxidative stress within the animal. This type of stress leads to damaged cellular structure and functions, inflammation, decreased performance and compromised fish quality (degradation of fats in the filet for example). The internal antioxidant enzymes (produced in the liver) help the animal to cope with the harmful effects of oxidative stress and are therefore important for overall fish health and quality.
The good thing is that the level of these antioxidant enzymes can be positively modulated through certain feed ingredients. In this trial, an increased activity of the antioxidant enzymes; superoxidase dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), and catalase (CA) was observed in the liver and blood sera of the fish fed P. rhodozyma compared to the basal diet. This led to an overall higher total antioxidant activity in the red yeast groups (Figure 2).
Antioxidant activity
rhodozyma in the diets and the lowest FCR was seen in fish fed 47g/kg diet. No mortality was seen in the experimental diets and the controls, however the basal diet treatment group had one death.
Filet quality and pigmentation
The researchers measured the highest filet protein content in the P3 diet group (Figure 3), but no significant difference was seen in contents of lipid, moisture, ash and pH values either among the
Antioxidant activities in serum and liver samples of trout fed P. rhodozyma were dose dependent and a higher dosage exhibited more antioxidant activity. Higher dosage of the red yeast also revealed a higher protein content in filets than fish fed synthetic AX and the basal diet, while water holding capacity and lipid loss in the filets of fish fed the experimental diets were lower. The best pigmentation color was seen in filets of fish fed higher red yeast concentration. Overall, application of P. rhodozyma at 47 g/kg diet in trout diets provides the best results in terms of performance, antioxidant activities, and filet pigmentation.

treatments or between treatments and basal diet. The water holding capacity and lipid loss in filets of all AX treatments were lower than fish fed basal diet and the lowest water loss was seen in the P3 group. Water and lipid losses should be avoided as much as possible, as this is an important factor, associated with the palatability, quality and acceptability of meat. When looking at pigmentation, the redness value progressive increased when P. rhodozyma concentration was increased. The highest value was seen in the P3 group. This was also seen for the yellowness level. Increasing carotenoid concentrations led to increased redness (a*), yellowness (b*). The P3 groups also showed the lowest percentages of HSI (Hepatosomatic Index) and VSI (Viscerosomatic Index). VSI and HSI indicate the amount of energy reserves stored in the liver and as fat in the viscera. Higher dosages were superior to lower dosages This study showed that P. rhodozyma, supplemented at a 15.5–47 g/kg diet inclusion rate leads to an improvement in trout growth. Higher dosages were superior to lower dosages. Trout fed higher doses of P. rhodozyma also demonstrated better growth than synthetic astaxanthin at 500mg/kg diet.

On a global scale, shrimp production has been climbing steadily since its inception, and in 2022, production is expected to exceed five million metric tonnes.
This year aquaculture farmers find themselves enjoying what’s been called a ‘bumper year’ for shrimp production. Demand is up, supply is growing, and profitability is being fueled. It’s a promising future for farmed shrimp, but with this promise comes a growing number of challenges to meet.
Shrimp farming developed in the 1970s in response to the depleted supply of wild shrimp and to meet the demand for this appetising seafood variety. Five decades have come and gone, and the demand for farmed shrimp has only grown, making it one of the most consumed seafoods in the world.Today, more than half of all shrimp is produced in Asia, while around 30 percent is produced in the Americas. Asia remains in the lead, but the Americas are catching up quickly and home to the most rapidly growing shrimp production markets in the world.
ingredients
Supplying
Farmers must be prepared to tackle everything from disease resistance in increasingly dense pond environments to securing a dietary feed that’s both sustainable and able to stimulate a healthy and growing population of shrimp. Today the ingredients in the dietary feed often face scrutiny in terms of both carbon footprint as well as their effect on shrimp performance. Farmers must ensure that their shrimp ingest the most efficient ingredients. This means they need ingredients that possess important nutrients that stimulate growth and lead to bigger, healthier crops, and are sustainably sourced and produced.
A bumper year for shrimp farmers
Feeding
sustainable
To support shrimp farmers in finding the most effective ingredients for dietary feed, researchers at Labomar, the Marine Sciences Institute in NE Brazil, set up a scientific study to better understand the digestibility of shrimp feed ingredients derived from aquatic sources as compared to plant and animal sources. The scientists’ intention was to discover which ingredient had the greatest digestibility of protein and essential amino acids in the right feed to ensure growth the global shrimp industry Ragnhild Dragøy, VP Product and Sustainability, Aker BioMarine,

Our head office and production site is located in Diepholz, Lower Saxony - in the immediate vicinity of the largest poultry production and processing facilities in Germany.
The various ingredients tested as part of the experiment included soy protein concentrate, poultry byproduct meal and several aquatic ingredients, including salmon byproduct meal and krill meal. Krill meal is sustainably sourced from Antarctic waters.“What this study revealed is that the aquatic proteins lead to the highest digestibility for shrimp, edging out the plant and terrestrial animal byproducts in their effectiveness as feed ingredients,” says Dr Alberto JP Nunes from Instituto de Ciências do Mar (Labomar), Brazil.
Testing dietary feed ingredients
Pacific whiteleg shrimp. This study is important as it has shown that protein and amino acid digestibility of raw materials have a greater importance than their crude values and should be carefully considered during ingredient selection and feed formulation.
The shrimp that consumed krill meal in their diet also had the best reported growth performance with highest weekly growth rate and the lowest feed conversion ratio.
Balancing effectiveness with sustainability
For aquaculture producers, finding a balance between ingredient effectiveness and sustainability is essential. With demand continuing its upward trend, farmers will be under pressure to produce bigger crops with large and healthy shrimp, all while meeting new and more comprehensive environmental targets.
Dietary feed ingredients will come under increased scrutiny in this context, which means that every ingredient must make a difference, but with very little carbon footprint.
At Aker BioMarine, sustainability is at the core of our business, so by including krill in aqua feed composition, the environmental impact of fish and shrimp can be reduced. This is important, as the composition of aquaculture feed is the single most important input contributing to the carbon footprint of aquaculture products.

The development and deployment of compact ROVs (remotely operated underwater vehicles) in recent years have immensely helped professionals overcome technical challenges and human risks involved with underwater operational work and deep-sea inspections, especially in the world of aquaculture.
Technology & innovation
How AI is helping fish farmers to redefine aquaculture operations by Qysea Technology, China
QYSEA’s newly developed AI Platform includes a range of adaptive position and vision locking systems for its entire line of FIFISH ROVs. Among these dynamic features, the Vision Lock system allows operators to visually secure onto selected targets across any underwater environment with ease and precision. The user needs to simply touch, swipe or pinch-zoom towards the area of interest on their device screen and the ROV then intuitively adjusts its position, locking the target at the screen center. From mort identification and retrieval to evaluating damages of fish farming nets and infrastructures, activating the AI Vision Lock unleashes a range of smart capabilities that ensure selected subjects are at the center of focus, alongside improving operating efficiency and resistance against currents for the user. Once locked onto the selected target and if the posture of the ROV -such as its pitch, direction, and rolls- is changed by currents, the FIFISH can intuitively re-adjust its position towards the original point of focus.
The key technology behind QYSEA's AI platform is the Dead Reckoning Inertial Navigation System (DR-INS). FIFISH ROVs utilise their built-in accelerometer and gyroscope to measure the acceleration and angular velocity of objects, as well as their computing systems to actively estimate and calculate the position, attitude, and velocity of objects in motion which results in a stabilised and smooth real-time target locking.
QYSEA addresses and overcomes these challenges by providing aquaculture farms with durable, simple-to-use, and affordable advanced underwater systems for daily fish farm operation and maintenance.
In light of recent breakthroughs and developments, QYSEA Technology and its innovative research and engineering team have launched an AI-based vision platform allowing users of its FIFISH Underwater Robots to achieve precise underwater and active visual locking capabilities.
The technology has been mainly used through aircraft, submarines, missiles, and space shuttles, where its technical threshold can be quite high. As a creative breakthrough within the fish farming and marine industry, the QYSEA R&D team has taken the lead in applying this technology to ROVs for the first time, successfully launching the AI Vision Lock platform following numerous trials and iterations.
Ensuring compliance with hygiene and health standards, maintaining fish farm infrastructure and equipment in proper operational conditions, as well as certifying the integrity of fish farms can come with various critical challenges.

Scientific studies (Sussarellu et al, 2016) found negative impacts on the reproductive function of oysters which ingested microplastic particles of polystyrene. Therefore, identifying the marine regions with a higher risk of marine plastic pollution is key for the offshore aquaculture industry, not only to protect the environment they operate in, but also to protect the quality of their farmed products and economic sustainability of their businesses.
Understanding the connections between marine plastic pollution and offshore aquaculture by Cleo Jongedijk, Research, Imperial College London, UK Marine plastic pollution is a present threat to the marine environment. More and more plastics are found at sea and affecting marine species, and the quantity of plastics entering marine waters is expected to increase even more in the next few years.Consequently, the impacts of the presence of plastics in the marine environment is currently an important field of study to understand not only its impacts on the marine species, but also on the marine-dependent industries, such as aquaculture. With the growing importance of aquaculture farms as a source of marine food, the impacts of plastic on the farmed marine species and of plastic from aquaculture farms on the marine environment, gain relevance too. The largest concentration of marine plastics is found in areas close to the coast. At the same time, the impact of marine plastics is the highest in these coastal waters as well. It is where the highest pressure on clean water is. Many different stakeholders – protected marine life, touristic activities and marine industrial activities including fishing and aquaculture farming – operate all in the same space. More than an aesthetic worry
The Sea Clearly project
For a while, plastic pollution was deemed to be, if anything, an aesthetic worry for coastal tourism and mechanical risk for marine life in the form of entanglement or blocked ingestion.
A potential source of pollution

Pharmaceutical residues and pesticides (Bringer et al., 2021), can be adsorbed by these particles and affect the farmed marine species too.
FISH FARMING TECHNOLOGY 38 | August 2022 - Fish Farming Technology
All of the above studies leave no doubt that for all parties, both the aquaculture industry and marine area regulators, it would be beneficial to have access to a good method of identifying the risk and spread of plastic pollution in the marine environment. This is where we joined in.
In early November 2021, Blue-Cloud announced an Online hackathon challenge which would entail 3 weeks of ideation journey with training sessions to introduce the platform to the participants. We formed our young and international team of marine plastic scientists from Utrecht University (NL), Imperial College London (UK), University of Bern (SUI) and the Florida State University (USA).
As a group we have been studying plastic pollution on a global scale for about a decade, and developed a wide understanding of how the oceans move plastic pollution around, where the sources are and how many factors like wind, currents, waves, but also size and type of plastic and interaction with biomaterials, effect the final fate of plastics, both in the open ocean and on coastlines. We decided to join the Blue-Cloud hackathon as an opportunity to bring our scientific knowledge closer to final users.
The main hackathon event was held from 07-09th February 2022. After three days of intense hacking action, mentor interactions and deliverable submissions, our project Sea Clearly won both the first jury prize of EUR€25,000 (US$25,500) and the Blue-Skies award based on public vote. We are creating a solution that is focused on the needs of Figure 2: Selected potential location for aquaculture farm (cross) with the potential pollution origin calculated from the ocean currents (top panel) and most likely pollution sources originating from the coastline to the farm (bottom panel).
In areas of high aquaculture activity, a large percentage of plastics on adjacent beaches can be traced back to the farms. For example, a study done at a beach on the French-Atlantic coast found that 70 percent of the plastics collected were from nearby oyster farms (Bringer et al, 2021).
An open science platform Blue-Cloud is an open science platform to develop solutions for marine ecosystems combining multiple databases containing about 10 million datasets from leading European marine data infrastructures.

Our hackathon case-study focused on microplastic (0.002 - 5 mm) pollution, however we are currently further developing our model for any inert pollutant data available on the BlueCloud.
An interactive website that displays simulated microplastic pollution trajectories that interact with aquaculture farms in the Mediterranean is live at the moment. This website is a prototype tool under continuous development that provides information on the geographic location of aquaculture farms in the Mediterranean, together with dynamic visualisations of the movement of microplastic pollution affecting these farms. Our prototype tool is available at https://ozavala.coaps.fsu.edu/particleviz/SeaClearly/ and uses the open-source lagrangian visualisation software ParticleViz. To give stakeholders a full opportunity to use all the knowledge that we gain during this process, we are currently working on a more comprehensive scenario tool where already in the early planning phase, locations in the mediterranean can be selected and a pollution risk assessment can be run whether or not there is already aquaculture present.
We implement our solution via forward and backward tracking of virtual particles to and from aquaculture cages, using an open-access particle-tracking framework, OceanParcels (www.oceanparcels. org). We include computer modelled 2D surface flow data to follow particles transported by ocean currents. We release virtual particles from the beaches and rivers, based on latest estimates of Mediterranean plastic concentrations (from Kaandorp et al. 2020, Meijer et al. 2021, Jambeck et al. 2015). We run the simulations for at least one year to account for seasonal effects.When a particle makes contact with an aquaculture cage we will record this as a potential consumption by marine species (or trapping by filter-feeders, like shellfish). We perform an advanced probability analysis to provide the most likely origin of the particles that reach aquaculture farms.

Simulated microplastic pollution
The technology that we accelerated during the hackathon will therefore provide a solution for this challenge by identifying the likelihood of aquaculture farms at specific locations to be contaminated by pollutants released from the Mediterranean coast. We also intend to provide pathways of pollutants or gear particles released from aquaculture farms to track their destination and prevent future contamination into surrounding areas (especially marine protected areas) from cages.
stakeholders who operate in and around aquaculture in coastal areas and are affected by marine plastic pollution. We have co-designed an open science project named Sea Clearly that aims to estimate the origin and destination of inert pollutants that interact with Mediterranean aquaculture cages.
This can be used to explore potential locations for aquaculture farms and provides detailed information about the dual risk of pollution to the aquaculture produce as well as the pollution from the farm to local and regional marine protected areas.

Feed Tables
can consist of more specific chemical compounds in different types of food brands. Some countries may even publish their own manual for specific industries and share it as an official guide.
Feed tables can be useful in setting a model for the amount of feed to be given to various stocks on average, but they do not delve deep enough into the variance of appetite many animals might experience on any given day. They are useful tools for farmers to use in order to ball-park a range of feed to distribute amongst their stock, but most animal farms are not impacted by wasted feed the same way that fish in RAS are.
Experienced aquaculturists can get their data on feed down to a very specific science. The problem with fish is that they are not nearly as predictable as many might think. You can calculate an estimate for how much you believe they will eat depending on several factors, but when you are paying record high prices for feed, estimating incorrectly can come at a high cost.
The other major issue with using feed tables in RAS is the consequence of overfeeding. With most animals, overfeeding is not a huge issue as it can often be used later or replaced with
How artificial intelligence is changing the future of aquaculture as we know it by Caitlyn Parsons, Marketing and Public Relations Associate, ReelData AI, Canada
One of the biggest motivators for moving fish farms to Recirculated Aquaculture Systems (RAS), is the ability to control almost every aspect of the fish’s life. RAS tanks have the ability to optimise production, improve living conditions for the fish, and increase biomass, among others. Even with this level of control, farmers face the continuous challenge of creating the optimal feed conversion ratio. As those in the freshwater aquaculture sector know all too well, feeding fish is a lot more complicated than it looks. The health of the fish is dependent on a healthy tank ecosystem; too much feed and you have problems, too little, and your fish don’t grow. Is your filtration system not working effectively? The left-over feed and faeces destroys the water quality. Finding the right balance is a constant battle with high-stakes when the health of your fish is concerned.Feedtables have long been the traditional practice to tackle these issues. Estimating the appetite of fish based on several factors like weight, age, and food quality is a costly and timeconsuming gamble that often results in inaccurate predictions. This can have high consequences on the overall health and wellbeing of the fish, and in the worst cases, cause fatalities.
Animals have a wide range of needs and this is especially true when considering how fish experience varying levels of stress throughout the course of a cycle. Stress events can inhibit appetites among the fish and stop them receiving the crucial nutrients needed to grow before harvesting.
FISH FARMING TECHNOLOGY
A feed table is information used by farmers and aquaculturists to determine how much food should be given to their stock. This information can change depending on a variety of factors like age, weight, diet, type of food, time of year, etc. Information from feed tables can be passed down through generations and upgraded over the years.

Before 2019, no company was able to do this with a high degree of accuracy, causing miscalculations and human error that put the stock at harm. New technology is needed to help slim the margin of error that challenges many farmers in the land-based aquaculture industry. Many of the more advanced farms have begun to look at innovative solutions for these issues, with many believing that artificial intelligence is the future of aquaculture.
With the current rate of population growth, there is more pressure on the food industry to create sustainably and ethically sourced protein. A new wave of start-ups have begun to look at ways to help support this growing industry.
Several of these companies have begun to make a name for themselves in ocean-based farms, but often this technology is not compatible with RAS. If as much of the future of aquaculture is in land-based facilities as many experts in the field believe, more technology will be required to support this growing sector.
Many companies in the industry have seen the issues that fish farmers face with managing feed and water quality in RAS tanks and have been working to find the right technology to properly count and adjust the feed amount in order to optimise the process.
ReelAppetite was the first product developed by ReelData, a Canadian company from Halifax, Nova Scotia. Since their inception in 2019, they have begun to make a name for themselves in their ability to help RAS farmers streamline their process while helping to ensure the health of their fish. Their products were created to support aquaculture farms, but with one significant difference that separates them from the rest: it’s

fresher feed. In land-based aquaculture, uneaten feed can deteriorate the water quality and cause a buildup of algae and other pollutants in the water. Poor feed quality can also cause harm to the delicate ecosystem of the tank and potentially damage the stock.
Innovative technology is continuously being developed to curtail miscalculculations to feed dispersion, but only one company has been successful so far in creating a completely autonomous device that is able to bypass all requirements of a feeding table and predict a fish’s needs to an incredibly accurate degree. The main difference? It’s all done with artificial intelligence.

ReelData’s AI has been shown to reduce spill by as much as 20 times in trials, whilst increasing growth up to 25 compared to feed table methods. Savings from wasted feed alone has been as much as US$3million per 10,000 MT annual production.
ReelData’s plans to create an all-inclusive A.I. suite will revolutionise the way that the world sees aquaculture. Through the safekeeping of fish in land-based tanks, ReelData’s AI Suite can succeed in aiding farms to produce sustainably sourced protein to help curb the global food shortage while guaranteeing a profit. The land-based aquaculture sector is growing quickly, and with these expected hikes in production, companies will require inventive solutions to help support the industry. To this end, the company’s AI technology has the potential to create tangible change in the way the world views the aquaculture industry, revolutionising the production process and helping produce sustainable and ethically farmed fish across the globe.
It can work in tandem with ReelAppetite or as a stand-alone product that removes the need for time-consuming weigh-ins that can halt production for days. The wonderful thing about ReelBiomass is that it can monitor the size and weight of your fish with high degrees of accuracy over time while removing the need for intrusive weigh-ins. These two products will be married into one platform that uses real-time feeding performance to monitor, evaluate, and predict production growth, unlocking a higher level of certainty within production planning, sales, and procurement.
What’s next?
controlled by AI. In calculating the precise amount of waste that goes unconsumed in each tank, the company’s ReelAppetite software is able to accurately predict what they will need for food. It works with the tank’s feeding technology to adjust the next feeding interval to the fish’s specific needs at that moment, limiting chances of the fish being underfed or overfed and optimising the tank’s water quality.
One of the downsides to RAS is the initial investment required to set up the system, but automating the most expensive area of aquaculture – feed – helps fast-track the return on investment and has the ability to save millions in the long-run.
AI can calculate the proper consistency of feed spill, which helps limit the amount of stress that fish experience in tanks while maximising their growth potential. Appetite is also a leading predictor of stress. Having the opportunity to monitor the stress levels of fish can help limit harmful behaviours that could affect the growth of the fish and lower their biomass.
Faster return on investment
In acknowledging that appetite is not always consistent or predictable, the company has found an innovative solution to an issue that has been stopping many ocean-based farms from leveraging RAS more extensively.
The company has also announced the upcoming release of a new product; ReelBiomass is a biomass distribution calculator that was created specifically for land-based facilities, making its calculations that much more accurate for the growing industry.
ReelData’s ability to create A.I. solutions to enable scalable productions is what has caught the attention of some of the biggest companies in the industry. ReelData today provides solutions to industry leaders such as Atlantic Sapphire, The Kingfish Company, and Salmon Evolution. With their passion for creating innovative tech solutions, the company came up with the AI Suite; a family of products that work in tandem to help automate and scale the production process in land-based facilities. Each product is designed to help with an area of aquaculture that is often the root cause of issues happening within a farm, while removing the margin of error that farms deal with regularly.
One of the biggest issues with land-based aquaculture is underfeeding, with farms underfeeding by as much as 25-50 percent. The high cost of feed together with the fear of damaging water quality causes many farmers to be conservative in their proportions which can cause stress and limit the growth potential of the ReelAppetite’sfish.

OptiTrap by ScaleAQ OptiTrap is a highly optimised dual drain waste collection system that allows for effective and efficient removal of solid waste in a RAS facility (such as uneaten food and faeces). Presenting a solution to the RAS facilities that must ensure good water quality, the system’s centre main drain handles primary water exchange while a smaller, integrated solids drain provides an in-tank solution for fast and efficient waste removal. Over 90 percent of settleable solid waste can be removed from the tank within minutes. RAS tanks can become self-cleaning as the system pulls solids to the middle of the tank where they are automatically removed. Using the OptiTrap system reduces the size and complexity of other waste solids removal technologies including drum-screen filters and bead filters. It can also reduce the size of the biofilter required to control ammonia nitrogen in culture water.

www.xylem.com International Aquafeed - August 2022 | 47
The Modular Rotating Biological Contractor (RBC) is the next natural step forward, from the trickling filter, to be used for both wastewater management and aquaculture. The Modular RBC is segmented into modules around a central shaft, with its filtration medium fixed to the central shaft. The system is then placed just a few inches above production tanks. As it is built in a modular way, the filter can be set up and customised for a number of different sizes. So rather than building a facility around a filtration system, the filtration system can be built around the facility’s needs. RBCs are installed at roughly the same level as the fish tank, so the energy needed to lift the water is reduced. The system is self-cleaning, as the rotation of the medium provides oxygenation, strips CO2 and removes excess bacteria.
Wedeco Duron is an open-channel UV disinfection system which has an integrated, compact, automatic lifting device and energyefficient, high powered Ecoray lamps. The Ecoray 600W lamps reduce required lamp count by more than 50 percent when compared with conventional, low-pressure amalgam UV Usinglamps.theDuron UV system customers can lower capital costs and energy consumption.

Lumpfish welfare Understanding the journey from research to farm
CSAR started the groundwork of producing lumpfish from UK native wild broodstock in 2014. It has been a long journey
Aquaculture case study
Dr Sara Barrento, Science Communication and Stakeholder Engagement Manager, Swansea University, UK
It was with farmers and lumpfish in mind that the Centre for Sustainable Aquatic Research (CSAR) at Swansea University, with the help of salmon aquaculture industry partners, developed the Lumpfish Welfare Watcher - a web-based & desktop application designed to help fish farmers assess and improve the welfare of lumpfish. The Lumpfish Welfare Watcher includes four complementary welfare tools: (1) a diagnostic chart for the rapid visual assessment of lumpfish welfare based on five operational welfare indicators; (2) an online BMI calculator for the detection of underweight fish; (3) a Rapid Welfare Assessment tool to calculate the overall welfare of lumpfish; and (4) an e-training platform to show fish farmers how to manage lumpfish welfare. These tools will help monitor and improve the welfare of lumpfish, reduce stress-related mortalities, and help make the emerging lumpfish farming industry in the UK more sustainable.
But how were these tools developed?
48 | August 2022 - International Aquafeed
CS Over 580 species of aquatic species are farmed globally - most are fish. Lumpfish is a novel marine species to aquaculture and one of the fastest growing farmed fish in Europe. But novel species are challenging - there is little information to guide best practices and as a result, this can impact their welfare. Lumpfish are unique as they are not farmed for human consumption, they provide a service to salmon farmers. Lumpfish are cleaner fish - they clean sealice from salmon.
The second activity invited participants to check pictures of lumpfish and score specific indicators based on the pictures. The indicators included: damage to the: suction disk, caudal fin, dorsal fin and anal fin. The scores 0 to 4, indicated the degree of damage to these fins – higher scores corresponded to greater damage.Finally, the group activity, consisted of a facilitated discussion on three topics: - List the challenges to implementing lumpfish welfare - List the solutions to implement lumpfish welfare - List the opportunities to implement lumpfish welfare Scientific publications These exercises focusing on the lumpfish indicators allowed us to better understand farmers’ needs and polish the final Lumpfish Operational Welfare Score Index (LOWSI), this work was published in Aquaculture, a scientific peer-reviewed journal. The overall outcomes of the workshop were also published in Reviews in Aquaculture. This article offers 16 practical solutions for improving the welfare of lumpfish and illustrates the merits of the Delphi approach for achieving consensus among stakeholders on welfare needs, targeting research where it is most needed, and generating workable solutions.
The first activity was an individual questionnaire where participants had to rate how useful 18 welfare indicators were. Then they had to choose from this same list of welfare indicators which were already being used at the farm level.
of trial and error, with the technical teams developing Standard Operating Procedures and supporting research students funded by the salmon production industry. Research led by Professor Carlos Garcia de Leaniz was essential to better understand lumpfish aquaculture, behaviour and health.
The afternoon workshop included five activities following the Delphi technique that aims to gain reliable expert consensus.
Dr Sara Barrento, Dr Carolina Gutierrez-Rabadan and Professor Carlos Garcia de Leaniz convened the First Symposium on Welfare in Aquaculture in May 2019. The event explored commonalities and differences in the welfare requirements of different farmed species and asked whether some common welfare metrics exist. The morning symposium was followed by a workshop on lumpfish welfare in the afternoon.
Symposium on Welfare in Aquaculture
By 2019, PhD student Carolina Gutierres-Rabadan sponsored by MOWI Scotland, had a long list of welfare indicators for lumpfish. But to implement them and make them practical for farmers to use, she needed to narrow down the number of indicators. So, the CSAR team decided to consult the industry.
The workshop focused on better welfare for better lumpfish and provided the opportunity for participants to: - Identify key limitations and challenges in implementing lumpfish welfare - Explore solutions and new services - Contribute to the publication of a lumpfish welfare code of Overall,practice78 delegates participated in the morning symposium and 53 participants attended the afternoon workshop.
The publication was awarded the Sena De Silva paper honorific title. This title is awarded to high-quality articles that excel in novelty and originality, with real-world applicability, a keen focus on environmental sustainability, and social responsibility.

The winner of the AFTaN 2022 Award is the 'M007 Cooler' by Agentis Innovations of Thailand which is a completely automated moisture control system for coolers.
AFTaN Awards - or the Animal Feed Technology and Nutrition
The judges awarded a 'Distinction Award' to the Famsun company of China, who also focused its entry on energy saving, in developing its 'Dryer Heat Recovery System' which uses the heat from low-moisture air to lower energy usage. It can reduce steam consumption by approximately 15 percent.
The volumes of grease used annually in rolls and the knowledge that the grease used finds its way into pelleted feed shows that this development offers greater sustainably while reducing the risk of feed contamination.
However, the judges could not overlook the significance of the 'Extruder Microfeed System' by Andritz, a system that reduces blockages at the die and can lead to a 30-45 percent increase in production, better energy utilisation coupled with easy installation.
The winning entry focused on the reduction of energy in the pellet drying process. Once again sensors and digitalisation are at the heart of this development which can achieve predetermined moist levels in finish feeds in real time. The system can be retrofitted into almost any vertical cooler and can be integrated into existing SCADA systems.
2022 Industry Events International Aquafeed - August 2022 | 59
Awards to give it its full name - has been introduced for the first time at Victam International 2022. The Award attracted a wide range of applications, many of whom were keen to demonstrate and compare their products and services with others.
The judges also considered products and services suitable for the aquafeed sector as a separate category and made two awards: the winner of the AFTaN Aquaculture Award goes to the SJPS156 Twin-Screw Extruder by Famsun of China. This machine boasts a wealth of technical advances which culminate in a significant decrease in the energy required in its production performance when producing both floating and sinking aquafeeds and/or the option of improving throughput by a further 20 percent.
The international panel of judges also rated as 'Highly Commented' an often overlooked aspect of pellet production with an award for the 'Lube for Life Rolls' by CPM. This company has taken technology from the heavy press industry and applied it to the production of feed pellets resulting in rolls no longer requiring lubrication.

He then went on to graduate from Nong Lam university in Ho Chi Minh, Vietnam, where back in 2006, he earned his undergraduate degree in aquaculture for shrimp farming. In addition to studying in Vietnam, Dr Loc Tran also earned a PhD in shrimp pathology, shrimp disease in Arizona, USA.
Okay so let’s say you have automatic management software. You can incorporate the real science into that kind of software, and we can have less human error. I can tell you that human error costs a LOT of money.
And I can tell you that in the past, when we talk about the shrimp feed, we had to harvest the raw materials and make it into fishmeal. This created a bottleneck because marine harvest is limited. But now we can make 100 percent fishmeal free, fish oil free feed. And the shrimp are still performing well.
As well as being the founder of ShrimpVet, Dr Loc Tran is also one of the key researchers behind the discovery of the causes of Early Mortality Syndrome (EMS) in shrimp.
In fact, we have to use all the resources wiser, that is why we are cutting back the use of fishmeal; because it feeds fish, it’s supposed to be fed for humans. In future, I believe we can have a much smaller carbon footprint for production, less nitrogen release, less pollutants, etc. In doing this, we can create a much more sustainable aquaculture industry to feed the world by 2050.

When he first started his career, he decided to conduct shrimp disease diagnostics, exactly as Dr Donald Lightner had taught him in Arizona. So, he set up a diagnostic laboratory to check for shrimp diseases, using various techniques including challenging the shrimp with different pathogens.
Dr Loc Tran, founder, ShrimpVet, Vietnam
And it was in 2013, just before he graduated from university of Arizona that he formed his own company. His work alongside academia doing research, with some very good mentors like Dr Donald Lightner and Kevin Fitzsimmons set him up nicely.
What new technologies do you see coming in terms of nutrition and growth to the shrimp industry in the coming years, where do you think it’s going to be? I would say that I foresee that in the medium term, in shrimp farming countries the use of technology has been increasing very rapidly, with Vietnam being a good example. I remember when I first returned to Vietnam at that time, the average wage for a farming worker could be US$200 per month. Now the same person doing the same job now gets maybe US$500. Why? Because they have so many more opportunities because the competition for workforce. And especially Vietnam with all the manufacturing industry that still attracts a lot of workers.
It all began for him during the late 80s or early 90s when he decided he needed a way to make a living. At the time he had a love of swimming creatures, which is what he credits as being his main reason for starting him gaining his education in aquaculture.
When he established a hatchery with the intention of improving this practice, he had so many people working in feed additives, genetics and probiotics, who wanted to jump on board to do something for the industry alongside him. This is why his company uses multidisciplinary approaches, which allows ShrimpVet to comprehensively assist producers in the industry to this day.
In your view what major hurdles do you still think Vietnam needs to overcome to improve shrimp production in the country? I would say there are several things that Vietnam needs to do in order to improve, I would say, improve their competitive advantages. One thing for real that I’ve been seeing, is the increased production costs, which one of the major things that is making Vietnam less competitive.
I would say we have been very smart to overcome this bottleneck. But one major concern that I have is about the sustainability of this industry. We should be able to reduce the waste released from the shrimp farming, we also have to use our water source more wisely.
I would say that we will have labour shortage for shrimp farms and also processing plants for sure. So that is why we may need more automation, we may need AI-incorporated management etc. And also, we may need to have more consolidation in terms of science for farming.
The third option is to shorten the supply chain. For example, let’s say a lot of small farmers have to buy feed and other supplies on credit with high prices. So eventually that adds up to their production costs making the shrimp, the production costs become very expensive and they cannot make a profit. Think about this – so if the industry is more consolidated, sizeable farmers can farm in a joint venture company to do the farming. And financially they should be strong enough so they can buy things with cash, they should have some sort of know-how in terms of doing the farm engineering, design, etc. They should have the know-how in order to, to choose better farming technology, business management, sourcing for good materials and so on. Then, if they do everything right, they can get their farm certified. When the farm is certified they will have the negotiation power to talk with the processor so they can sell things fair prices etc, so they will make more profit. I would also say that the problem in Vietnam is that they have so many small farmers, so it’s very much fragmented. Now it’s not easy to incorporate all the good things into all the technology may work if you have a sizeable business, not like a small household. That is also the reason why you see that in countries like Ecuador, the main reason they’ve been doing extremely well is that their companies are more consolidated.
International Aquafeed magazine caught up with Dr Loc Tran recently to ask him his thoughts on the industry’s past, present and future as well as the need to increase sustainability and reduce human error.
When we talk about a sizeable business with multiple plants, we need to incorporate more technology. Let’s get back to 2015 when I first visited Ecuador. At that time the farming was very primitive. The ponds were super big – two to five hectares with manual feeding and no electricity. These days, they now use solar power more frequently, along with automatic feeders with AI incorporated feeding base, allowing many advancements in terms of technology can be incorporated. How you feel about the industry and its ability to feed 9.6 billion people by 2050? Is aquaculture in good enough shape, is it continuing in a good way? I would say that aquaculture can feed the world by 2050 with no problem at all. I would say that all the technology that we develop allows us to have much higher productivity, allowing us to feed people.
These high production cost could be firstly due to diseases, so when you have more diseases that means the success rate is reduced. The second is choosing the right farming models, with the right farming system still being very important.
