The health beneficiary very long chain omega-3 fatty acids EPA and DHA are only found in marine ingredients, while the shorter chain alfa-linolenic acid (ALA) are found in several plant oils. There is a global lack of marine oils for use in fish diets due to an increased demand from the aquaculture industry and human consumption sectors. The overall aim of OMEGA3GENOMICS is to increase the genetic capacity of Atlantic salmon to synthesize, utilize and deposit omega-3 fatty acids while maintaining good health. We have in earlier projects shown a significant genetic variation in the capacity of Atlantic salmon to synthesize the omega-3 fatty acids EPA and DHA from ALA, and that this variation impacts the capacity of the fish to cope with different diets, lipid storage, survival and inflammatory status. The EPA and DHA contents in the muscle does not only depend on the capacity to synthesize EPA and DHA in the liver, but the omega-3 fatty acid bioconversion also includes uptake, transport, deposition, mobilization, oxidation in other tissues and organs including muscle. In OMEGA3GENOMICS, this complex genetic basis of this trait will be approached by a combination of genome-wide association, transcriptomics, epigenetics and genomic prediction studies. Results aim to be directly relevant for the aquaculture selective breeding, feeding and production industries in their work to reduce the dependence on marine oils.
