Due to shortage of fish oil, such knowledge is necessary for sustainable growth of the salmon industry while securing fish health. To solve this challenge, a unique project consortium has been assembled, including the three major players within research on lipid nutrition in salmonids in Europe (Nofima, Nifes, University of Stirling), two of the major feed companies (Biomar, Skretting), as well as partners with particular expertise in the areas of immunology, gill infections and neuroendocrine stress response (UiO, NIVA, Uppsala University). In this project, EPA and DHA requirements during long-term growth in sea cages will be fine-tuned in the area between 10-16 g/kg of the diet, where knowledge is currently lacking. The potential impact of lipid level on the requirement will be studied. Shorter term land-based trials will distinguish the health effects of the level of n-6 fatty acids from the n-6/n-3 ratio and the n-3 level, as well as give information about the effects of the different n-3 fatty acids (EPA, DHA and ALA) alone, in combination and in different ratios. Furthermore, the impact of genetic background and life stage of the fish will be studied. All trials will include assessment of the retention and deposition of EPA and DHA in whole fish and different tissues, as well as evaluation of health status and study of lipid metabolism. Additionally, as the dietary fatty acid composition needs to be adequate for fish exposed to the various challenges in commercial aquaculture productions, our land-based trials will include tests of how the fish cope with hypoxia/ chronic and acute stress, a gill infection challenge and vaccination with subsequent evaluation of immune responses.
