Africa: Coastal rivers of Kenya from the Mwena River to the lower Athi below Lugard's Falls; also near its mouth, including Lake Chem Chem; Lower and middle Tana River, Northern Uaso Nyiro, Juba system and Webi Shebeli; Nguruman; and Ethiopia (Ref. 5166). Probably also in Lake Momello, south of the Kenya-Tanzania border (Ref. 5166, 118638). Three subspecies are recognized: Oreochromis spilurus niger, Oreochromis spilurus percivali and Oreochromis spilurus spilurus.

Ciclo de vida e comportamento de acasalamento
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
Spawns in shallow water with shelving bottom in ponds. Size of first spawning depends on population density (lower at higher densities). Mating pit is the size and shape of a saucer. Eggs probably fertilized before being taken into the mouth by the female, or are fertilized inside the mouth (Ref. 2).
