Culturing fish is a very old practice in Africa, although commercial production of fishes is still developing throughout the continent. Some species and strains of fishes are in particular suitable for commercial production. The Nile Tilapia (Oreochromis niloticus) is one of these very important fishes, introduced from Africa and the Middle East to several countries elsewhere in the world. Now it has become popular in commercial and
subsistence aquaculture ventures. China and other Asian countries are famous for their bulk contribution to global aquaculture production of tilapia and other fishes. The sector incorporates not only rearing fish for harvest, but also hatcheries, feed processing, environmental issues, genetic and species diversity, post-harvest processing, economics, as well as improvements through research and knowledge transfer.
