Africa: Lower Zambezi and southwards in the lower parts of the Sabi, Lundi, Pungwe and Buzi Rivers (Ref. 5166); also Ruvuma River on the Tanzanian-Mozambique border; Lake Rutumba, Lupululu system, and the Lupuledi west of Lindi (Ref. 5166). Previously, two subspecies were recognized: Oreochromis placidus placidus and Oreohromis placidus ruvumae.

Short description Morfología | Morfometría

Espinas dorsales (total): 16 - 18; Radios blandos dorsales (total): 10-13; Espinas anales 3-4; Radios blandos anales: 8 - 11; Vértebra: 29 - 31.

Prefers quiet pools with marginal vegetation; it has been reported only from fresh water and low altitudes and latitudes, so that its salinity and temperature tolerances are probably narrower than those of O. mossambicus (Ref. 2).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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).

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).

Price category (Ref. 80766): Unknown.
