Today, an increasing proportion of fish oil in feed is being replaced by vegetable oils, which leads to a reduced content of the omega-3 fatty acids EPA and DHA in salmon fillets. It is important to understand the mechanisms behind and the extent of the natural ability of salmon to convert 18: 3n-3 to EPA and DHA, so that one can utilize this knowledge to optimize the use of fish oil and increase the deposition of EPA and DHA in fish muscle. .
Nofima has a project through the Research Council of Norway (207621 / E40), (“Towards a sustainable salmonid aquaculture - Salmon as a net producer of n-3 fatty acids” 2011–2013), where the goal is to show that one can improve the retention of long omega-3 fatty acids by combining genetic selection and the right feed. In this project, several family groups have been produced where parent fish are selected from families with high or low expression of delta-6 desaturase, an enzyme that is necessary for the fish to be able to convert the short omega-3 fatty acid 18: 3n-3 to them. long omega-3 fatty acids EPA and DHA. In order to make better use of the unique fish material that has been produced, a research project is planned with 4 different work packages that will provide supplementary knowledge:
WP1) “Nutritional programming of salmon fry”
WP2) “Comparison between freshwater and seawater in the period up to 400-gram size”
WP3) “Effect of genetic background on deposition of EPA and DHA in fillets up to slaughter size”
WP4) “Interaction effects between genetics and omega-3 level in feed on health and quality in fish for slaughter ”.
Increased knowledge to solve the challenges with limited access to marine omega-3 fatty acids is central to the objectives for both FHF and Nofima.
Goal: to improve the utilization of omega-3 fatty acids in salmon farming.
