A diet that includes fish with a high long chain (LC) ω-3 fatty acids (FAs) content, more specifically ecosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are known to have numerous health benefits for consumers. What are the different natural sources/product (what are the better ones / is the best one?) that contains ω-3 FAs and can effectively be used with feed to enrich farmed fishes, particularly tilapia?
