Abstract: AbstractAdequate dietary supply of eicosapentaenoic acid (20:5n‐3) and docosahexaenoic acid (22:6n‐3) is required to maintain health and growth of Atlantic salmon (Salmo salar). However, salmon can also convert α‐linolenic acid (18:3n‐3) into eicosapentaenoic acid (20:5n‐3) and docosahexaenoic acid (22:6n‐3) by sequential desaturation and elongation reactions, which can be modified by 20:5n‐3 and 22:6n‐3 intake. In mammals, dietary 20:5n‐3 + 22:6n‐3 intake can modify Fads2 expression (Δ6 desaturase) via altered DNA methyla...
