Globally, aquaculture has been identified as the surest alternative to capture fisheries (fishing from open water bodies) and a potent entry point at increasing fish production, poverty alleviation and job creation. However, the greatest problem facing the development of aquaculture enterprise is inadequate and high cost of fish feed which accounts for more than sixty percent (60%) of the total cost of fish production at farm gate. Hence, adequate and cost-effective input such as affordable quality fish feed must be provided for commercially important tropical fish species like the African catfish and Nile tilapia to increase fish production and profitability in aquaculture enterprise in Africa. Unlike terrestrial animals (poultry and other livestock) feed formulation for aquatic animals is uniquely different and must essentially takes cognizance of the aquatic environment and nutritional requirements of cultured fish species.
