Cargill EWOS Technical day

Day one saw attendees receive a welcome from Aquaculture New Zealand’s Technical Director Colin Johnston. This was followed by a full on day of 20 presentations across two halls, the majority of which divided into the salmon stream and the diversification & resilience stream. The presentations covered a wide ranging scope, with an opening plenary featuring Global Aquaculture Alliance’s President Dr George Chamberlain discussing aquaculture’s number one issue globally – biosecurity, sharing with the audience his experiences internationally with biosecurity. The second plenary speaker was Associate Professor Christopher Burt on strategies to improve employee safety, highlighting the ever present problem across industries that is new employees’ safety and how to address this. Topics were discussed throughout the day by University professors, research institute scientists, and industry representatives, ranging from ocean acidification, the potential of seaweed, right through to antimicrobial coating and surface additive solutions for the processing stage. Attendees I spoke to said they had especially enjoyed a block dedicated to research and development, a topic especially relevant to the relatively young industry of aquaculture where innovation is both commonplace and necessary. David Koedyk of Baldwins Law Limited gave a presentation and answered the audiences in detail on the intricacies of intellectual property law and the processes businesses should aim for. This was followed by presentations on the supply chain, the importance of precompetitive R&D, and a panel discussion. The day was closed with the New Zealand Salmon Farmers Association meeting for members and invited guests.

Garry Seidl, Managing Director, Hexcyl Systems, Australia We produce an extremely robust shellfish basket with a unique and highly efficient design that is ideally suited for use with the adjustable long line oyster farming system. Our latest range of products has been on the market for approximately two years but the first of the baskets has been available on the market since around 2008. At the moment we sell into mainland Australia, France, USA, Canada, Japan, and of course here in New Zealand. The key benefit of these baskets is their longevity and robustness so material selection was a key criteria when we started the project back in about 2005. At the time we identified one of the biggest problems in aquaculture was that a majority of the infrastructure components going into the marine environment were substandard. A unique feature of our 25 litre shellfish baskets is the patented connection system where the suspension system connects to the body of the basket. The unique design of this connection system helps to eliminate unnecessary and destructive wear of critical components. Whenever you put something into a marine environment one of the key failing is wear, because of the constant motion of the environment. This is my second time at this conference, I was here two years ago and so it has been great to come back and re-visit and see where the industry is progressing and as you can see there is some really good technology coming out in sub-tidal shellfish farming for mussels and those same technologies can be adopted for oysters. There is a real cross over for some of the larger fin fish farming operations that are also considering delving into shellfish. So the industry is really bouncing back particularly after the pacific oyster mortality syndrome, it is great to see all of the hard work that has been done over the past years coming to fruition.

The conference

The official conference was officially opened with a mihi whakatau (formal Māori welcome) performed by Archdeacon Harvey Ruru. Most notably in his welcome he acknowledged how the decisions made by attendees throughout the conference is for the future children of New Zealand. The conference day offered over two hours of refreshment breaks sponsored by the Cawthron Institute, New Zealand King Salmon, BNZ, and NMIT. The presentations were generally more conceptually focused rather than technically focused like those the day prior.

Aquaculture New Zealand’s A+ Certification

In recent years Aquaculture New Zealand has developed a sustainable management framework called A+. It is a world class sustainable management framework which enables the New Zealand aquaculture industry to better engage with our communities and continuously improve our environmental practices while strengthening global demand for New Zealand's farmed seafood. In an interview Aquaculture New Zealand’s Environmental Manager, Rebecca Clarkson on A+ she explained, “One of the arms of our organisation’s strategy was environmental sustainability. We started thinking of ways we could assist the industry in demonstrating their sustainability and we decided we could help the industry join a certification program such as GAA (Global Aquaculture Alliance) or ASC (Aquaculture Stewardship Council).” She continued, “What came out of market research and cost-benefit analysis was that with such a range of markets and producers in the New Zealand industry, it didn’t suite for everyone to meet that high

Mike Baker, Co-Director, N-Viro Mooring Systems and Marine Flex Elastic Mooring Systems We are involved in all aspects of underwater anchoring and environmentally friendly mooring. Marine Flex is a rubber cord mooring system which replaces anchor chains that cause a lot of disturbance and liquefaction of the seabed. Ofcourse being a natural rubber product it is environmentally friendly, supported by a screw anchor system which has a small footprint, and can take on very high vertical loads. We developed the screw anchor system nearly 30 years ago and have since done over 20,000 of them in New Zealand and abroad. However Marine Flex is a relatively new development which we have brought into the market place, a lot of companies have shown a huge interest in it, including Aqualine, Norway. It removes anchor chains which are very destructive on the sea floor, the anchor chains are metal products with a high corrosion rate, so the elastic mooring has been very well received by the industry. This is our first time at the Aquaculture New Zealand Conference, we have really enjoyed the feedback we have had today. A lot of the people here are our clients, it has been nice to sit down in a non-working environment and talk about future products. Of course the industry is moving offshore into much more harsh environments, so this type of product is very useful.
