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.

Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 14 - 17; Rayons mous dorsaux (Total): 10-13; Épines anales 3; Rayons mous anaux: 9 - 10; Vertèbres: 28 - 30. Scales on cheek in 2 or 3 series. Genital papilla of male conical or club-shaped, with a sub-terminal pore. Females and immature males have a yellow-buff background color with a series of mid-lateral blotches and a more dorsal parallel series. Mature males golden-yellow; conspicuous bright blue areas on dorsal, anal and pelvic fins; orange or red dorsal lappets.

Biologie     Glossaire (ex. epibenthic)

Feeds on insects, plants and diatoms (Ref. 2).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

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).
