For a great number of important cultured fishes, reliable estimates of nutrient requirements have been established. It is noteworthy that comparable estimates are found between species with similar feeding habits and that inhabit the same ecosystem.

Researchers are constantly generating information regarding the nutritional value and suitability of common and also for novel ingredients used in aquafeeds. Continually applying this knowledge to the formulation of diets and feed management practices will result in improved production of healthy animals that is both more efficient and more cost-effective.
