Salmon is the farmed animal that utilises feed most effectively. Today, 1.15 kg feed is used to produce 1 kg of salmon. Though the content of marine omega-3 in farmed salmon has decreased due to the increased use of vegetable raw materials in the feed, salmon remains a very good source of these healthy fatty acids.
Traditionally, fish meal and fish oil have been the most important components of the feed, but recent years have seen an increase in the use of vegetable raw materials. About 70% of the ingredients in the feed are now vegetable, while the remainder come from marine raw materials.
Fish meal and fish oil have traditionally been produced from so-called industrial grade fish, i.e. fish that are not normally used for human consumption. Global production of fish meal and fish oil has been more or less constant over the last 40 years. More recently, trimmings and by-products from fisheries have become an important source of materials in feed.
The government sets requirements to ensure that the feed is of high quality, that the fish are not harmed by the feed and that people who eat the fish are not harmed in doing so. These are common requirements throughout the EU/EEA. The Norwegian Food Safety Authority verifies that companies producing fish feed comply with the legislation. In addition, Norway has a national monitoring programme for undesirable substances in fish feed. This has shown that the feed is safe for fish and provides safe and healthy food for the consumer. Both the Food Safety Authority and the Norwegian National Institute of Nutrition and Seafood Research can provide further information.
