Abstract Dietary requirements for amino acids and fatty acids have been reported for channel catfish (Ictalurus punctatus), salmonids (Oncorhynchus spp.), common carp (Cyprinus carpio), tilapias (Oreochromis spp.), and eel (Anguilla japonicus). Most of the vitamin and mineral requirements are available for channel catfish and salmonids, and some are available for common carp, tilapia, eel, and other finfish and crustaceans. From this available information, cost-effective feeds can be formulated for the major commercial aquaculture species. Major differences in nutrient requirements between fish and mammals or birds are as follows: fish have a lower digestible energy:protein ratio (8 to 10 kcal of DE/g of CP for fish vs 15 to 20 kcal of DE/g of CP for livestock); fish require n-3 fatty acids and land animals require n-6; fish can absorb minerals from the water, which negates the need for some minerals in the diet; and fish have limited ability to synthesize vitamin C and must depend on a dietary source. Areas for further research include 1) refinement of nutrient requirements of the major culture species considering effects of fish size, temperature, and management; 2) nutrient requirements of crustaceans; 3) effects of nutrition on fish health and product quality; and 4) feeding technology.
