Just like us, the salmon is not dependent on particular food, but on particular nutrients such as amino acids, fats, vitamins and minerals.
In nature the salmon finds the nutrient in the food available in the rivers and the ocean. When producing the feed, we can find the nutrients the salmon need in many sources.
The key part is that the right balance of the right nutrients are there. The salmon diet consists of much protein and fats, and little starch. Salmon does not digests starch very well.
In salmon feed much of the protein wild salmon gets from eating fish is replaced with vegetable proteins from like soy. And much of the fats are replaced by rapeseed oil. By using less marine resources in the feed, the biodiversity footprint of the value chain is reduced.
In the marine environment there is pollution from human activities, as dioxin, PCBs etc. These substances get into the food chain in the sea and are found especially in the marine fats. When replacing marine fats with vegetable fats, we get less such undesired substances into the feed.
Marine Omega-3 acid is very health nutrient for both the salmon and humans. The marine Omega-3 acid comes mainly from fish oil, but much attention is now also on novel sources for marine Omega-3 acid. Replacing fish oil with vegetable oils had reduces the content of Omega-3 acid in the salmon, but the salmon gets what it need and salmon remains a very good source of Omega-3 in our diet.
The feed we use in Cermaq varies according the fish type (Coho, trout, Atlantic salmon), natural conditions (e.g. temperature and light situation), size and age of the fish, and other. Cermaq does not reject the use of genetically modified feed ingredients, but adapt to customers preferences and do not use any gm-ingredients in the feed used in Norway.
Cermaq does not produce feed, but set detailed specifications for the supply from feed producers. We also do tests of the feed.
Our code of conduct for feed suppliers contains requirements to sustainability for all marine and no-marine raw materials and for the social dimension.
In the annual report we report on the composition of and sources of our feed at aggregated level.
