The demand for fish oil rich in omega-3 has long been greater than the supply. Sources that can meet the requirement for omega-3 in the diet of farmed fish have until now been scarce. However, new sources of omega-3 are partly on the market and research shows that these are safe to use in farmed salmon feed.

A new doctorate shows it is possible to change the fatty acid composition of farmed salmon through breeding. It can further help to utilise omega-3 in feed more effectively.

Previously, Nofima scientists have reported that salmon skin is strengthened if there is enough omega-3 and zinc in their feed. A new report shows that these nutrients also provide an important interaction in the intestines and likely the gills of salmon.

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.
