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.

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).非洲: 在 Lugard 的秋天之下的對 Athi 下游的肯亞從 Mwena 河的沿海的河川; 也在它的嘴的附近, 包括湖 Chem Chem; Tana 河下游與中游, 北方 Uaso Nyiro , Juba 系統與 Webi Shebeli; Nguruman。 可能也在湖 Momello 中, 肯亞南方-坦尚尼亞毗鄰。
