Alternative feed raw materials

The nutritional requirements of fish change according to species, in addition to growth and developmental stage.  

Maintaining good fish health depends on the identification of nutritional requirements during different phases of their life span.  As the nutritional content of vegetable products differs from that of marine organisms, the composition of nutrients is also different.  Much of the research carried out under the Aquaculture Nutrition Research Programme relates to the nutritional needs of fish and how the composition of proteins and fatty acids in different feeds and feed raw materials affects the energy and nutrient metabolism of the fish and its development.  

Fish metabolize the nutrients they absorb from the feed in different ways, depending on which feed ingredients have been used, and the balance between different nutrients.  Fish fillet composition can also be altered by feed composition.  Several of the nutrients stored in fish fillet have a positive effect on our health.  Some of the programme’s research effort is therefore focused on finding ways of enriching the nutrients in the fish muscle.  The aim is to produce a healthy farmed fish, especially rich in health promoting nutrients.
