Quarantine was placed on the site on November 27, 2012 and remains in place to control movements of people, vessels, equipment and ���sh onto or off the site. WHAT IS INFECTIOUS SALMON ANEMIA? Infectious salmon anemia or anaemia, is a viral disease of Atlantic salmon that affects ���sh farms in Canada, Norway, Scotland and Chile. According to provincial government information there is no risk to humans associated with ISA, and the ���sh are safe for human consumption. The virus would have to be present in the environment, or introduced, for ���sh to contract the disease. According to provincial government information the source of the pathogen in the CoB is most likely to be naturally occurring. $21M OF NEW FUNDING TO BENEFIT RESEARCH PARTNERSHIPS The Government will invest $16 million over seven years in the Pastoral Greenhouse Gas Research Consortium and $5 million over a maximum of seven years in Seafood Innovations Limited, Science and Innovation, Minister Steven Joyce announced on February 4, 2013. The Pastoral Greenhouse Gas Research Consortium; a partnership between AgResearch, DairyNZ, Beef+Lamb NZ, Fonterra, Landcorp Ltd and DeerResearch, will develop new technologies that farmers can use to reduce greenhouse gas emissions without loss of productivity. Seafood Innovations Limited, a partnership between Seafood New Zealand, Plant and Food Research, NIWA, and Cawthron Institute, will develop new products, processes and services in the seafood value chain to improve New Zealand���s competitive advantage and to grow premium value seafood exports for the New Zealand seafood industry. Joyce says, ���The Government is committed to getting better value from science ���ndings by our businesses, industries, and other end-users, to ensure that the purpose-driven research we invest in, bene���ts New Zealand.��� US AQUACULTURE 2013 US Aquaculture 2013, the Triennial meeting of the Fish Culture Section, American Fisheries Society, World Aquaculture Society and National Shell���sheries Association was held on February 21-25, 2013 in Nashville, Tennessee. US Aquaculture 2013 had 15 concurrent sessions over four days covering all aspects of aquaculture, with many workshops and meetings, and one of the largest aquaculture tradeshows in the world. Combined with social functions and entertainment there were many opportunities to network with others from around America. Associations holding their Annual Meetings at Aquaculture 2013 were: the National Aquaculture Association, US Aquaculture Society, the Aquaculture Suppliers Association, the American Tilapia Association, the Striped Bass Growers Association, the US Trout Farmers Association, the Zebra���sh Husbandry Association, the Aquacultural Engineering Society, and the International Association of Aquaculture Economics and Management. BALLAN WRASSE COMBATING SEA LICE The Research Council of Norway says that sea lice parasites in Norway have become resistant to chemical treatment methods in���icting estimated losses to Norway���s aquaculture industry around NOK 500 million to 2 billion yearly. Until recently sea lice research has been focused on vaccines and other pharmaceutical measures. But now, a cleaner ���sh called the Ballan wrasse is being enlisted to eat mass quantities of sea lice directly off infected salmon. Ballan wrasse alone will not be able to defeat the parasite, but Per Gunnar Kvenseth of Villa Organic, a seafood producer on Norway���s west coast, believes that this ���sh species could be a key weapon in the arsenal for ���ghting sea lice, ���As juveniles they can be placed in the cage together with salmon juveniles, and the two species will grow up alongside each other. The fact that Ballan wrasse are so hardy, and that they maintain such a high activity level throughout the winter, makes them better suited to the task than any other type of cleaner ���sh we have experimented with.��� Up to 300 sea lice have been found in the stomach of a single Ballan wrasse grazing among farmed salmon. The main obstacle to using Ballan wrasse within the aquaculture industry is that Ballan wrasse of the size needed are in short supply in the wild and will require hatcheries and feeding tanks on land. There are also challenges relating to light conditions and other aspects of Ballan wrasse production. They estimate that 15 million Ballan wrasse will be required. Workers must ensure that the Ballan wrasse do not simply feast on molluscs and algal growth instead of feeding on the salmon parasites and growth must be removed from the nets, which has the added bene���t of improving seawater exchange within the net, yielding higher-quality salmon. GEODUCKS A HUGE SUCCESS AT CAWTHRON OPEN DAY! Cawthron���s third annual open day was an eye-opener for a crowd of more than 300 enthusiastic visitors in February. The days have proved so popular with people wanting to learn more about aquaculture that the institute requires advance bookings. ���Otherwise we get inundated on the day, which is fantastic,��� said Jo Thompson, the institute���s community educator. This year tour groups were limited to 12 at a time to make sure that everyone got a good view. It was the third annual open day at the centre and visitors who took the hour-long tours were able to see the institute���s research into selective breeding of paci���c oysters, greenshell mussels and scallops, and its groundbreaking cryo-preservation work, the freezing of shell���sh sperm, eggs and larvae in liquid nitrogen. Geoducks were the biggest hit at the Glenhaven Aquaculture Centre. Visitors were given the opportunity to see the curious clams up close and to even handle them. Thompson, said visitors were excited to see and hear about a species they were not familiar with, that had ���huge potential��� for export. ���There���s a massive market in Asia, and we���re in the research stage to see how we can grow it commercially.��� AFL INVEST IN NEW ZEALAND OYSTER INDUSTRY Cawthron Institute and Aotearoa Fisheries Limited have signed an agreement that will see AFL take over and expand Cawthron���s commercial oyster nursery and spat growing operation at their Aquaculture Park at Glenduan, north of Nelson. Cawthron Institute will continue to produce and supply oyster larvae to industry. Cawthron Institute Chairman Ian Kearney says, ���Cawthron Institute has developed a scienti���c selective breeding programme for oysters over the last ten years.Three years ago we established the outdoor nursery to grow and supply increased volumes of selectively bred spat to the industry.��� AFL will now take over the expanding spat production supplying Paci���c oyster larvae to the industry from March, 2013. SPATnz will continue to produce Greenshell mussel. DEVELOPING AQUACULTURE IN THE BAY OF BISCAY The AZTI-Tecnalia technological centre is undertaking a number of scienti���c analyses on the technical and socioeconomic viability and markets, to evaluate the possibility of diversi���cation of ���shing activities in the Bay of Biscay. The study identi���ed marine zones off the Basque coast with conditions that guarantee the correct locating of longline systems in the open sea. AZTI-Tecnalia also did a pilot trial for the production of bivalve molluscs in the open sea in 2011 and 2012 although the results of this study are not available.The results have shown opportunities for longline systems in the open sea off the coast of Basque Country in the Bay of Biscay. The project is being undertaken for the New (2009-2013) Strategic Plan for Fisheries and Aquaculture of the Basque Government. MARCH/APRIL 2013 ��� NZ AQUACULTURE ��� 5
