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.

It is important to minimise the risk of disease in cod aquaculture. Scientist Rama Bangera of Nofima has studied the effect that the cod’s genes have on its resistance to three fatal diseases, and found that the resistance of farmed cod can be increased by selective breeding.

A collaborative project between Norway and India has discovered markers for genes that control resistance against the bacterial disease Aeromoniasis in rohu carp. Aeromoniasis is a devastating disease that affects aquaculture of this and many other carp species throughout the world.

Farmed salmon is rich in fat, but fillets of farmed salmon contain less marine omega-3 than previously, because a large fraction of the fish oil in the feed has been replaced by plant oil. Scientists have discovered a way of stimulating farmed salmon to convert plant oil in the feed to marine omega-3.

Phosphorus is a vital mineral that must be added to salmon feed to ensure that the fish grow normally and develop a healthy skeleton. Global reserves of phosphorus, however, are limited, and industries that depend on this mineral must increase their use of current sources. An unexploited gold mine of phosphorus for the aquaculture industry is available in filleting waste.

Through the EU-project AQUAEXCEL, European researchers can apply for conducting research experiments at several aquaculture research facilities in Europe. In Norway, Nofima has two research facilities that are very modern and highly equipped, with plenty of opportunities.
