Ecology Summary - Oreochromis macrochir

语言:

主要参考文献	Trewavas, E., 1983
附注	Found in quiet waters along river margins and backwaters, in floodplain habitats and impoundments; juveniles live close inshore in shallow water (Ref. 7248, 52193). Inhabits the high plateau of the savanna, south of the rain forest; remains an inland species with no spread into coastal ecosystems; very low salinity tolerance (Ref. 2). Survives in ponds and dams (Ref. 4967). Frequency of occurence in Caprivi: frequently in sandy streams, abundant in standing deep water, common in shallow swamps, and occasionally in shallow flood plains (Ref. 37065).
