The feed revolution continues

Norway’s Prime Minister Erna Solberg recently referred to salmon as “Norway’s IKEA”, because people buy and eat Norwegian salmon all over the world. In the same way as IKEA needs materials to build furniture, salmon need a feed on which they can grow. The feeds that are currently in use consist principally of raw materials from plants. A revolution in feed has been under way for the past 15 years. And it’s far from over.

Genomics to combat shrimp disease

Shrimp aquaculture is carried out in large parts of Asia and Latin America. White spot syndrome is one of the most serious diseases of farmed shrimp, and there is currently no effective way of combating this disease. Scientists have recently discovered markers for genes that determine how well black tiger shrimp resist the disease. They are now planning to look for the genes in the white shrimp.

Algae may replace fish oil in salmon feed

Fish oil is an ideal source of omega-3 in salmon feed, but the capacity to produce farmed salmon using fish oil as the main source of omega-3 in feed is limited, if the farmed salmon itself is to remain a rich source of omega-3. This means that the salmon feed industry needs access to large volumes of new ingredients that contain omega-3. Experiments at Nofima have shown that a type of algae known as “heterotrophic algae” can fully replace fish oil in feed used for small salmon.
