The present study evaluated the effects of dietary fish oil replacement with linseed or sesame on sperm quality and reproductive performance in rainbow trout (Oncorhynchus mykiss) during a 7-month feeding trial. Male (≈ 970 g) broodfish were fed three isonitrogeneous isolipidic formulated diets containing (FO diet), (LO diet) (SO diet). Commercial diet was to another group serve as control (CD). Growth not affected by diet. Slight variations volume, pH density recorded semen produced subjected different treatments (p > 0.05). Similarly, motility kinematic parameters influenced However, osmolality differed groups, from SO LO having comparatively higher values < Fatty acid (FA) profile spermatozoa reflected FA composition. showed evidence de novo biosynthesis eicosapentaenoic acid, docosahexaenoic arachidonic acid.
