In West Africa natural distribution covers the basins of the Senegal, Gambia, Volta, Niger, Benue and Chad, with introduced specimens reported from various coastal basins (Ref. 53405). Widely introduced for aquaculture, with many existing strains. Several countries report adverse ecological impact after introduction. The following subspecies were previously recognized: Oreochromis niloticus baringoensis, Oreochromis niloticus cancellatus, Oreochromis niloticus eduardianus, Oreochromis niloticus filoa, Oreochromis niloticus niloticus, Oreochromis niloticus sugutae, Oreohromis niloticus tana and Oreohromis niloticus vulcani.

Diagnosis: jaws of mature male not greatly enlarged (length of lower jaw 29-37 % of head length); genital papilla of breeding male not tassellated (Ref. 2). Most distinguishing characteristic is the presence of regular vertical stripes throughout depth of caudal fin (Ref. 4967, 53405).

Occur in a wide variety of freshwater habitats like rivers, lakes, sewage canals and irrigation channels (Ref. 28714). Mainly diurnal. Feed mainly on phytoplankton or benthic algae. Oviparous (Ref. 205). Mouthbrooding by females (Ref. 2). Extended temperature range 8-42 °C, natural temperature range 13.5 - 33 °C (Ref. 3). Maximum depth from Ref. 34290. Marketed fresh and frozen (Ref. 9987).
