Researchers have evaluated how climate change could affect Norwegian salmon farming over the next 50 years.

Norwegian salmon producers are among the most efficient in the world. But although production costs in Norway are increasing to a lesser extent than in recent years, it is becoming increasingly expensive to farm salmon.

Nofima has a world-leading interdisciplinary research environment for the delicacy that will spearhead Norwegian seafood exports: Crab.

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.

Anna Sonesson is the new Research Director for the Breeding and Genetics Division at Nofima.

In a comment published in the journal Nature Sustainability, international scientists urge world leaders to initiate measures ensuring equitable sharing of marine resource benefits and minimizing burdens.

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.

Scientists at Nofima have now found that a mixture of a Norwegian plant oil and fish oil from the North-Atlantic can stimulate animals and humans to form healthy omega-3 fats themselves.

Last week, researchers and industries from all over the world met for a symposium to dive into research on fish skin, gut and gill tissues in aquaculture. The idea was to direct more attention to preventive fish health.

“Municipal coastal planners are being subjected to a lot of criticism for failing to take everyone’s interests into account, although they do an important and good job,” says senior researcher Ingrid Kvalvik at Nofima. Researchers are now going to investigate how coastal managers can do an even better job.
