Modification of membrane fatty acid composition, eicosanoid production, and phospholipase a activity in Atlantic Salmon ( Salmo salar) gill and kidney by dietary lipid
Abstract Atlantic salmon post‐smolts were fed diets containing either fish oils (Fosol, FO and Marinol, MO) rich in long‐chain n‐3 polyunsaturated fatty acids (PUFA), or plant oils rich in 18:2n‐6 (sunflower oil, SO) or 18:3n‐3 (linseed oil, LO) for 12 wk. The major PUFA in individual phospholipids...
