Better feed, better fish

Scientists at Memorial University, the University of Prince Edward Island and aquaculture firm Cargill Aqua Nutrition are using genomics to help the aquafeed industry develop feeds that improve the health of farmed salmon and protect them against sea lice and pathogenic viruses and bacteria. In the past 20 years, aquaculture production in Canada has more than doubled to close to $3.1 billion in economic activity a year. The industry now employs about 15,000 Canadians and exports 101,000 tonnes of food products. However, the health of farmed salmon in Canada is perpetually threatened by infectious diseases, including those caused by sea lice, pathogenic viruses and bacteria.
