  4. 4. O ver the last three years Hvalpsund has been involved in developing a revolutionary new stock protection system for Huon Aquaculture in Tasmania,Australia. Huon is a vertically integrated company, farming, processing and selling premium quality Atlantic salmon and rainbow trout products to domestic and international markets. As the only 100 percent Australian-owned salmon farming business in Australia, Huon employs over 480 staff and will produce around 15,000T of salmon and trout this year Huon owners, Peter and Frances Bender approached the Danish net manufacturer at Aquanor back in 2011, as they wanted to find partners to develop a new system to keep out seals and birds. Seals, in particular, prove a real headache in Tasmania, costing the company in the region of Aus$12-18 million per year. These costs come from direct losses caused by seals getting into the pen and killing the fish, as well as the impact of stress induced in the salmon by the seal attacks. Moreover, the risk of attacks means that the company needs to have dedicated teams of staff patrolling the marine farm leases day and night in an attempt to keep seals away from the pens and off the collars, as well as employing extra personnel to release any seals that get into the pens. Not only is killing seals strictly forbidden in Australia, but any death of a seal would also be very negatively perceived by the public. As a result, the company recognised that huge savings could be achieved by develop- ing a better way to fence off the seals from attacking fish and to improve safety for per- sonnel working on the farms. They had tried various net materials in the past, but with poor effect and now they wanted to go into a completely new direction that would improve safety for both fish and personnel. Hvalpsund suggested a trial using the ultra- strong and light Dyneema® fibre for the nets – a material they have plenty of experience of working with. Some of the early tests showed that it was not enough just to spec up the twine size, however – finding the right combination of twine size and strength and combining both knotted and raschel knotless materials eventu- ally proved to be the key. As no other salmon farm in the world had ever required nets with such high strength, the project was truly revolutionary. By trialing different kinds of nets and pens Hvalpsund worked with Huon to determine the best system to keep seals and birds away from the fish and feed. Key to the design The key to the design is the use of an extra-wide, triple-collar stanchion that has specialised outer sockets to accommodate a seal fence post and bird net pole. The seal fence post allows an outer seal fence net surrounding the entire pen to rise 2.8 metres above the surface of the water. The idea of the extra wide pen is to main- tain a good degree of separation between the outer seal fence and the inner containment net. The outer seal fence net is made using 125mm black knotted Dyneema® with a breaking strength of over 1200kg. It is also fitted with strong Dyneema® vertical ropes from which the sinker ring is suspended – by hanging the heavy sinker rings directly from the seal net it is kept as tight as possible all the time, which makes it more difficult for the seals to push the net or bite it. The inner containment net is made with light yet strong Dyneema® which ensures good water flow through the pen and reduces fouling. As the outer seal net is permanently in place, the pen is kept as a safe work environ- ment where daily operations or net changes can be done without the risk of seals attacking stock or personnel. The wide clearance between the outer seal net and inner containment net means that the nets can be cleaned using in situ net wash- ers. The system also includes an ultra-light bird net that is suspended high above the surface by light, flexible poles. The specially-designed, injection-moulded HDPE stanchions can be fitted with walkway plates either between the inner collars or both collars. This design provides a safe work- ing space for doing daily operations on the pens, even in bad weather. The advantage of using a pen made with only HDPE is that it requires far less maintenance than pens with steel components. Huon is also now investi- gating the potential for the pen stanchions to be constructed with injection-moulded nylon which, if successful, will make the stanchion even stronger. The original trial has proved to be so suc- cessful that Huon has now decided to replace all their existing pens with the new system. However, the real benefit will not come into play until all the pens at the site are replaced – as long as some of the pens with the old design are still in use the seals will target these. Hvalpsund Net is a family-owned and -run company based in Denmark with 20 employees in the headquarter, warehouse in Hvalpusnd. The company has its own pro- duction in Poland with 80 workers – mainly assembling aquaculture nets. Main export areas are Faroe Islands, Iceland, Scotland, Spain, Malta, Malaysia and Tasmania. The focus at Hvalpsund Net is to make cages, nets and mooring system for offshore aquaculture sites.

  6. 6. “IT GOES WITHOUT SAYING THAT YOUR BUSINESS STANDS WITH THE RIGHT INFORMATION BUT CAN FALL BADLY WITH INACCURATE WEIGHTS AND FISH NUMBERS.” T hat’s a quotation by Steve Bracken of Marine Harvest Scotland which Hermann Kristjansson, CEO and co- founder of Vaki Aquaculture Systems Ltd, began his talk at Aquaculture UK 2014 recently in Aviemore, Scotland. Mr Kristjansson presented his experience and views on Biomass Control, which has been listed as one of the challenges in Scottish salmon farming and in salmon farming in general. Started Vaki when he graduated from the University of Iceland in 1986. Since then he has concentrated on developing fish counters and size estimators for fish farming. Three years ago, Marine Harvest, Salmar and Leroy formed a pro- ject with SINTEF in Norway, the largest independent research institute in Scandinavia, to improve the Biomass Control in salmon farming. The total budget of the project, called EXACTUS, was UK£3 mil- lion, which confirms the importance of Biomass Control as seen by these three companies. A recent study conducted by PHD student Arnfinn Aunsmo from Aas University in Norway shows that the error in number of fish and average weight harvested from individual cages is high. The error reported on average weights is more that +/- five percent in 30 percent of the cases. There is evidence that show similar figures in Scotland even though aggregate results often show that people are harvesting approximately what they expect from a complete site. Serious problem Biomass Control is considered a serious problem/challenge in fish farming. Now, why is it a challenge? Everybody can agree that poor bio- mass control can lead to unnecessary negative environmental impact. But what Mr Kristjansson addressed is the challenge of getting the most out of production: How to achieve maximum yield with minimum cost. Very few people are concerned with the profitability of salmon farming today given the current price of salmon. But over the past 28 years that Mr Kristjansson has been in the industry, prices have not been very stable and he thinks it would be considered irresponsible not to prepare for some price fluctuation in the near to medium future. In order to achieve maximum yield at minimum cost, higher indus- trialisation of the farming process is required. “Tight monitoring and control of factors, that can be controlled, is needed. We need to collect as much data as possible and go into as much detail as possible monitoring exact weights and numbers all the way from hatching to harvest,” he explained. Mr Kristjansson’s experience is that numbers in freshwater are quite reliable in Scotland. All freshwater producers are using Vaki’s Micro and Macro Fish Counters successfully. Vaki would like to conduct regular training to make sure there are no surprises and everybody is up-to- date in the use of the equipment. Smolt delivery One of the most critical points in production from a Biomass Control perspective is the smolt delivery. The number and weight of smolts introduced into each cage is absolutely critical because it represents the starting point in an ongoing production. Things could also be improved here with regular training and regular validation of counts from the wellboats. “As many of you know, our counters record the counting process so counting can be validated afterwards and in fact, if the customer doesn’t want to do it himself, they need only to forward a recording file from the counter to Vaki. “Currently, we are developing an online database which will receive and store these recording files automatically from customers for later reference or validation.” Accuracy needed The ongoing part of the production is the most challenging for biomass control. Taking a manual sample of 100 fish from a cage is both physically challenging for the fish and the fish farmer and it is just not accurate nor reliable enough, referring again to Arnfin Aunsmo in Norway and to statistical theory. “There is a case study from EWOS Innovation in Norway that shows this clearly,” he says. “When the information about the Biomass in individual cages is not available or inaccurate, growth cannot be monitored and feeding not controlled in an effort to obtain the lowest feed conversion rate possible.” Low FCR is of course one of the most important indicators of low production cost as you know, he adds. “Therefore, monitoring the FCR based on real growth is essential if one wants to control the feeding. Monitoring the periodic FCR based on real growth is also essential if you want to analyse high FCR periods and takes some actions or implement improvements before the next production period.” He says a company might want to reduce its FCR from 1.4 down to 1.2. How can they do that without knowing the real growth over short periods? he asks. Biomass Control helps industralise salmon farming further 04 | INTERNATIONAL AQUAFEED | Fish farming Technology FISH FARMING TECHNOLOGY
  7. 7. “Monthly hand sampling of 100 fish does not provide enough accuracy to build results on.” Vaki have been working with its customers to identify and focus on periods of high FCR in order to identify the reasons behind this and improve the situation. The only way to monitor and improve FCR is to measure real growth continuously and accurately. He quoted another example, saying a customer in Canada, who monitored the growth with Biomass Daily, confirmed a very high FCR for two months. When analysing the period the customer found out that due to very high currents, some of the feed drifted through the cage before the fish could eat it. “The customer is going to try to avoid this next production cycle by moving the feed input towards the current and perhaps try to feed the fish when there are low tidal currents.” Future developments The Biomass Daily system has been developed for some years now and Vaki will continue to develop it to provide even more valuable information to the customer. Vaki will do this by comparing cages in the same site with cages in another site, benchmarking with anonymous cages in the area and comparing with the last production cycle. Vaki have developed a sonar specifically to find at which depth most of the fish are in the cage, to put the frame there in order to measure most fish and a winch system to move the frame between depths. Biomass Daily can be used to monitor the biomass from hatching to harvest. Vaki have developed a morts counter with LiftUP from Norway. The morts counter will automatically send data to the Biomass Daily system to make sure that the number of fish in the cage is maintained accurately. According to major sources, Biomass Control is one of the biggest challenges in salmon farming. Biomass Control is also one of the big- gest opportunities in salmon farming as a part of increased “industriali- sation” of the fish farming process which needs to take place in order to meet future challenges.

Of course we at IAF were keen to learn the facts and Mal Scott, general manager for Mohn Aqua UK, based in Forres, Scotland, was more than happy to talk us through the product. The Airmar DB11 used to be imported and sold here in the UK by Mohn Aqua. The DB11 was for a long time, “the best Seal Deterrent on the mar- ket” but now, with Airmar’s blessing Mohn Aqua have taken the DB11 and redesigned it for the better, creating what is now known as the MAG Seal Deterrent. It is made fully in the UK and has been built in consultation with, approved and tested by Airmar. Sturdy foundations Its foundations are sturdy, using much of the technology that the DB11 originally incorporated. Just like the DB11 the MAG Seal Deterrent sends out an omnidirectional pulse that hurts seals ear drums, yet with the MAG deterrent, “The pulse on each projec- tor can be set to go off at different intervals and for varied lengths of time, making the sequence appear random.” In the past, some seals had learned to predict a pattern. The MAG Seal Deterrent is 50 percent more effective than the DB11 and so it further helps prevent losses. Its only been on the market for a few months. A company reported UK£91,000 loss then got a new MAG Seal Deterrent box fitted and didn’t lose a single fish. Companies have to keep good records of seal attacks and seal deterrents. Mal explained all supermarkets audit the fish farms where they source their fish, using standard industry auditors in the UK like the RSPCA and Freedom Food Alliance. “None of the old systems would tell you if the system was faulty, the only way of knowing was to lose fish to seals and with the MAG Seal Deterrent its easy to find out.” explained Mal. Fault detection can be done daily with the MAG Seal Deterrent. A main problem that used to go undetected quite often was a damaged projector cable. But when you go through the test sequence each day - these things are easy to identify. The product works by firing a pulse that can cause pain to a seal’s eardrums within 60 metres of a fish farm. Seals can get used to noise but not pain; yet it won’t deafen seals as alternates through many frequencies. MAG was conscientious when it came to cetaceans (whales, porpoises and other mammals) and is confident that the MAG Seal Deterrent causes little acoustic interfer- ence to them. Aquatic China 2014 21-22 SEPTEMBER 2014 Kuntai Hotel Beijing, China part of: Beijing www.aquafeed.co.uk/aquaticchina Throughout the world consumers’ behaviour and attitude towards food has been changing and, as a result, the industries supplying food need to focus on the exchange of information in order to meet these new demands. The emphasis of the Aquatic China 2014 two-day conference is creating an opportunity pathway for those in China’s aquaculture industry to connect with some of the world’s experts on aquaculture research, science, nutrition, feed formulation, economic production, food safety, quality assurance and certification.

  9. 9. Fish farming Technology | INTERNATIONAL AQUAFEED | 07 FEATURE Feed barge innovations for the Faroe Islands JT Electric and Sandgrevstur joined forces to create innovative feed barge solutions for Bakkafrost, the leading producer of top quality salmon in the Faroe Islands. Oddvald Olsen, Bakkafrost’s farming manager has been work- ing in the sea-farming industry for nearly 30 years. During that time he has been following the development of feed barges. In his opinion, “traditional feed barges are not suitable for the farming environment in the Faroes.” Mr Olsen had been contemplating the idea of creating a suitable solution for many years. Now, JT Electric’s Olavur Thomsen and Sandgrevstur’s Gordon Martin Midjord have made that idea a reality. “Some were of the opinion, of course that we went back in time by rebuilding out-of-date cargo vessels into feed barges,” explained Olsen. “But as these vessels are built for sailing the open seas and the hold is quite suitable for silos, I was convinced they were right for the project.” The capacity to carry Sandgrevstur largely sell and transport raw material for con- crete and asphalt production. They are always on the look out for ships that have the capacity to carry a large amount of cargo and they always know which ships are on the market. This combined with JT Electrics knowledge of feeding systems makes for a winning union. Back in August 2013 Skavahamer - the first of the custom- made feed barges was delivered to a Bakkafrost fish farm. Skaverhamer was a succeeded by a second vessel Svarthamar, which was delivered to another Bakkafrost feeding site in April this year. Each fish farmer was involved with the process of designing the barge to meet the requirements of the site. The feed barges are unique and built according to customer demands yet they share defining characteristics. Each barge is extremely stable and suited for exposed sea. They are high capac- ity and can carry 600 tonnes of feed or more. Each feed barge has a very long berth side enabling feed and work-boats to safely lie alongside and both have a high life expec- tancy due to the thickness of the steel from which it is made and each vessel has large fuel and water carriage capacity. The up-cycling aspect of these feed barges is appealing and is economically rewarding. JT Electric explained it is not always about using the most expensive materials, it is more about using the materials that are right for the job. And in this case they hit the nail on the head. “The barges work just as well as I had imagined’ explained Mr Oddvald who says, “We are quite satisfied with them as they are suited to their position in the open sea, where the waves are high from time-to-time.” Dryden Aqua active filtration media Dryden Aqua’s exhibition stand at Aquaculture UK 14 was laden with little sample sachets of emerald green Active Filter Media (AFM) that people were urged to pick up and pocket. I have pinned the little sachet onto my notice board at work! For me - it serves the purpose of a souvenir and brings back memories of Aviemore and Aquaculture UK; forget stuffing a suitcase full of haggis and bagpipes. Staring at this little sachet of AFM is enough to take me back to the highlands. Obviously, it is so much more than a souvenir and the little sachets also fell into the hands of some of the big names in aquacul- ture; all of whom could be seek- ing innovative filtration solutions within the aqua sector for filtration purposes. AFM is made in the most sophisticated glass plant in Europe from recycled Scottish green glass cullet and bottles. The Dutch olympic team train in AFM- filtered pools and that’s understandable as this report shows AFM is confirmed to be twice as good as the best sand or glass filtration media in cleaning water. Let me just conclude by saying how charismatic and informative Dryden’s representatives were. Analytical chemist Christi Ashley Sing and engineer Mutassim Ghzali were great ambassadors for the product. www.drydenaqua.com Stirling graduate appointed by Meriden Animal Health University of Stirling graduate Kat Konstanti has been appoint to the position of International Technical Support Specialist for Meriden Animal Health. Ms Konstanti’s main focus will be to support the drive and growth of Meriden's products in the aquaculture industry through her technical knowledge and understanding of the market. She recently graduated with a Masters in Sustainable Aquaculture. During her studies at Stirling in Scotland, Ms Konstanti investigated several aspects of aquatic animal culture and gained a solid understanding of the principles that surround the aquaculture industry. With a focus in aquatic animal health control, nutrition, food safety and practical feed production, Kat's studies have set her up well for her career with Meriden. Kat will also be providing addi- tional technical support to the other species areas of the business; however her main focus will be on aqua. "Meriden has gained a solid base in the aquaculture industry since re-formulating its flagship product to create Orego-Stim Aquatract and developing Phyconomix," says Kat speaking of her appointment. "It is my goal to continue the development of these products within the aquaculture industry which is in dire need of effective, natural and sustainable products." Orego-Stim Aquatract has been formulated to reduce mortal- ity, increase harvest weight per area and provide support against stress during vaccination and grading. The product is available in both liquid and powder form. Phyconomix is a ready-to-use range of algae-based products that mirrors optimal larval diets encountered in the wild. Available in powder and liquid form, the nutritionally complete products produce healthier, more resistant post larvae for on-growing.
  10. 10. 08 | INTERNATIONAL AQUAFEED | Fish farming Technology FEATURE Remote interface assists controlling feed and fish in transit Pentair’s new Remote Interface Unit (RIU3) is a modular system that offers a high level of monitoring and control when it comes to feed in transit and in storage. The original RIU was a great achievement in linking the vari- ous stages of fish transportation. However, the new RIU3 which took a year in development and is based on customer inputs, is set to further its capabilities while providing a user experience that is less complicated through more simplified controls of just four buttons. International Aquafeed was interested to learn at Aquaculture UK 2014 about the installation of RIU3 on monitoring multiple trailers carrying live fish simultaneously. This utilises five direct inputs and five relay inputs to monitor the fish accurately and ultimately lead to reduced operating costs. Arvotec, the Finnish company who have previously featured in our magazine, use real-time software from Pentair in their products. Higher waves, stronger currents do not upset Faroe fish farmers Battered by extreme weather and sea conditions in a natural envi- ronment far more hostile than most other places, Faroese fish farms are built to last, using the most robust equipment in the world, according to Vónin Aquaculture. For most fish farmers, a wave height of eight metres is rather unthinkable, not to mention a current strength of 0.8 metres per second. Now go to the Faroe Islands and you will soon see that such conditions are considered nothing out of the ordinary - that is, they are quite common during winter in certain locations, as measured in 100-hour blocks. Extreme conditions by Faroese standards, is quite a different thing. Back in November 2011, Landsverk, the Faroese Public Works Agency, recorded wave heights of up to 19.7m, in fact the highest ever since records began in the late 1960s - possibly the highest on record anywhere, according to the agency. Even on that occasion, Faroese fish farms largely suffered no significant damages, however, one installation had its anchorage compromised and started drifting. “I remember this person was nervous about his fish farm which had shifted position by some 70m in a very short time,” said Signar Poulsen, manager at Vónin Aquaculture. “One of his larger floating frames had snapped and was only being held together by the net cage itself, which fortunately was made of very strong Dyneema netting. “So this was an emergency situation and we had three service teams mobilised to make sure the fish farm remained safe. It turned out to be intact except for the anchors used for keeping it in place and the one floating frame which had been broken in two but was held together by the net cage itself. We had it all repaired and back in place in a matter of hours. “The anchors were of the most robust kind but they had been dragged across the seabed by the force of the sea with the upper parts completely deformed. So the person was very happy to see everything resolved and the installation back in place with no dam- age to the fish farm.” Mr Poulsen added, “But such incidents are extremely rare in the Faroe Islands; I cannot recall any other time that something like this happened.” Three times stronger Out of a total of 36, two fish farming locations in the Faroe Islands regularly have currents of up to 0.8 metres per second while two other have wave heights of up to eight metres. As far as con- cerns equipment, the ability to withstand the elements is a standard requirement. Today, every aquaculture installation in the Faroes uses equip- ment from Vónin Aquaculture, Mr Poulsen says. “Our offerings range from complete solutions to component parts, from net cages, plastic cages, to mooring systems and acces- sories.” Vónin net cages are usually made from nylon, dyneema, polyester or polyethylene. What separates a Vónin net cages from others is the design of the net cage. A Vónin net cage is designed in particular way which enables it to be used at more exposed and shallow sites. Fish farms are essentially underwater installations and according to Vónin, their mooring system outperforms other systems on the mar- ket, much thanks to a unique design that includes a shock absorbing function that enables the installations to remain firmly moored to the seabed while seamlessly withstanding the forces of the sea. “We have 14 departments spread over the whole North Atlantic Ocean, spanning five countries. Canada, Greenland, Norway, Faroe Islands and Denmark,” he says. Vónin net cages and mooring systems undergo rigorous quality tests in order to ensure strength and quality is never compromised. All Vónin products come with certifications. Ropes from Knox Star Netting is a product with a worldwide patent pending for the fibrous polymers used and consists of new ropes from W&J Knox – a company first established in 1778 – and having a range of purposes to meet many challenges in fish farming. The unique properties are hydrophobic qualities and easy clean- ing; no algae or other materials in the water are able to stick to it. The benefits of the technology have been developed with other partners to deliver superior technology with friendly, built-in anti-seal strength ropes for fish farmers. The technology is at a very high level but is not just for aquacul- ture, says the company.
  11. 11. Kaycee’s twin-dose syringe Kaycee is offering a new twin-dose syringe that is the culmination of significant research and development in response to the needs of the aquaculture industry. Samuel and Adam Sesemann told International Aquafeed maga- zine that Kaycee has been building high-quality, hand-held repeater syringes serving the international animal health industry for over 50 years. For use with all oil and water-based vaccines, it is known for reliable dose accuracy while still being easy to maintain with fully replaceable spare parts. With its distinctive blue grip and polished chrome finish it has changed little over the years and due to its truly ergonomic and well-balanced design their syringes are com- fortable to use, allowing long sessions while mini- mising operator-fatigue and ultimately reducing costs. Built with chrome- plated metal to ensure a long life and endure the rigours of outdoor use in the agriculture and aquaculture industries. “As with all our syringes the hand-operated, twin-dose repeater syringe has been designed for use with all oil and water based vac- cine and specifically designed to deliver two vaccines of differing viscosity in the same dose. “It has two adjustable dose ranges of 0.05ml each, 0.1ml each or 0.05ml and 0.1ml. Staying true to the design of our current syringe range it is comfortable to handle, ergonomic in design, allows for long sessions minimising operator fatigue and will ultimately reduce the costs of vaccination,” says the company. Kaycee Veterinary Products Ltd was founded in 1962 and has been owned and run by the Sesemann family since 1976. Based in England, their products are shipped internationally.
