Food security, environmental concerns and the work on fish health and welfare have high priority in the management of Norwegian aquaculture. A sustainable aquaculture industry is one which is operated in an environmentally sound manner and adapted in accordance with concerns for the marine environment and biodiversity.
Seafood and health
Fish and other seafood contain high levels of many nutrients, and are good sources of proteins, fats (especially the long polyunsaturated marine n-3-fatty acids), vitamin D, vitamin B12, selenium and iodine.
Foreign substances and the use of medicines
State monitoring programmes document that it is safe to eat farmed salmon. The National Institute for Nutrition and Seafood Research (NIFES) analyses several thousand samples from farmed salmon every year. The 2012 results, based on samples from about 11,600 fish, show that the content of foreign substances is at the same level as those found in mackerel and herring.
Fish health/salmon lice
All salmon farmed in the sea are vaccinated against a number of diseases, primarily bacterial diseases. Consequently, the use of antibiotics in Norwegian aquaculture industry is extremely low.
