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.

Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
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。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 2.6 ±0.35 se; based on food items.
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (tm<=1: multiple spawning per year).
Fishing Vulnerability (Ref.
59153): Low vulnerability (18 of 100).
Nutrients (Ref.
124155): Calcium = 32.9 [12.2, 191.3] mg/100g; Iron = 1.36 [0.64, 2.82] mg/100g; Protein = 17.4 [15.7, 19.1] %; Omega3 = 0.186 [0.086, 0.409] g/100g; Selenium = 64.5 [27.3, 139.1] μg/100g; VitaminA = 8.03 [1.52, 36.61] μg/100g; Zinc = 2.2 [1.2, 4.8] mg/100g (wet weight); based on
nutrient studies.
