1431 Oreochromis esculentus (Graham, 1928) Cichlidae Cichlids Pseudocrenilabrinae Cichliformes Teleostei Singida tilapia Africa: Lake Victoria, Lake Nabugabo, Lakes Kyoga and Kwania, the Victoria Nile above the Murchison Falls, Malawa River and Lake Gangu (Ref. 5166, 34290) in Tanzania, Uganda and Kenya (Ref. 3); but now extirpated from the main lake body and the only natural remaining populations are those of satellite lakes (Ref. 118638). The species has been introduced into dams of the Lake Victoria catchment, as well as the Pangani catchment, Zigi River, Malagarazi River, Lake Rukwa, Wami River and the central Tanzania lakes surrounding Dodoma and Tabora (Ref. 118630, 118638). Introductions in the Akagera lakes in Rwanda (Ref. 1739, 54979) seem to have been based on erroneous tilapia identifications (Ref. 46152).
