Comparison of EPA and DHA utilization in Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) fed two diets with different content of fish oil and rapeseed oil
Atlantic salmon and rainbow trout with initial weights of 460–468 g were fed two diets either high in fish oil (FO) or rapeseed oil (RO) content. The abilities of the fish to metabolize and deposit lipid and n-3 fatty acids were compared. Growth rates, FCR, and fat digestibility were similar in both...
