feed for fish and fish as food
Aquaculture nutrition
Fish farming is on the rise, and forecasts show that in 2030 the global production of seafood from aquaculture will be equal to that from the fisheries. Feed for aquaculture has traditionally consisted of fish meal and fish oil. However, limited access to feed raw materials from the fisheries, combined with a growing need for fish feed, has prompted the exploration of using alternative feed raw materials to fish meal and fish oil. Vegetable oils, vegetable meal and krill meal are examples of possible alternatives.
A balanced nutritional composition of feed is vital for both normal development of farmed fish, ensuring good fish health and generating a healthy product for consumers to eat. The Aquaculture Nutrition Research Programme studies the nutritional requirements of farmed fish and the effect of nutrients and other substances in the feed on the health, wellbeing and development of the fish. In particular, it is important to establish how different nutrients in feed affect each other, and what consequences this has for the health of the fish.

A prerequisite for changing the composition of fish feed,
e.g. by including a large proportion of vegetable components, is an
understanding of how to balance the nutrients in the new feed in
order to ensure good health, wellbeing and development of the fish.
Today, commercial fish feed may contain up to 50% vegetable oils
and 50% vegetable proteins as replacements for marine raw
materials. Understanding the consequences of changing the
composition of fish feed is necessary when authorities draw up and
develop regulations governing the use of feed and feed raw
materials for fish.
