The microalgae we use are from the group diatoms that originate from the Arctic and along the coast of North Norway. The diatoms are rich in omega-3 lipids and protein. They are photosynthesisers and grows fast (40 - 50 mill/L and > 100% increase/Day). Until few years ago fish/salmon feed contained large amounts of marine biomass, mainly fish oil/meall and grinded small fishes. The source was fishes from South America and e.g. some herring and capelin. These sources has diminished since fish is also attractive human food. Some overfishing has also occurred. As a replacement the feed producers has added large amounts of terrestrial crop biomass, e.g. soy and rape. This is not sustainable, the use of terrestrial biomass has also caused some health problems in addition to that the content of the healthy omega-3 fatty acids in salmon has decreased substantially. The aquaculture industry therefore is in need of more marine biomass/feed. Also, if aquaculture shall expand in the future new sources for marine biomass are sought for. Marine microalgae are therefore here ideal candidates, not only because they are rich in lipids, but also since the production is sustainable and sequesters CO2 from factory fumes. Another problem that hampers aquaculture is salmon lice. Today in Norway >6 billion NOK/Year is used to fight lice. The methods are mechanical or chemical, and sometimes harms the fish. Tests that we have performed has shown that inclusion of microalgae (diatoms) in the feed can reduce lice infestation rate statistically significant. The present project therefore will produce algae biomass and test salmon growth, health and lice infestation in large scale fish pens, i.e. at realistic industrial conditions.
