Distribution and remarks: native to areas of northern, western and eastern Africa. This includes the coastal rivers of Israel and the Nile basin from the Albert Nile (including lakes Albert and Edward) to the delta, including the Blue Nile with Lake Tana. This species also occurs in Jebel Marra in Sudan, the lakes and rivers of the Ethiopian Rift valley (including the Awash River), in the endorheic lakes Turkana and Baringo and associated rivers, and also in lakes Kivu and Tanganyika including the Rusizi and lower Malagarasi systems ( Trewavas, 1983). In West Africa, the natural distribution area covers the basins of the Senegal, Gambia, Volta, Niger, Benue and Chad. It has been introduced in many fish culture stations, from where it has regularly escaped. Therefore, it has often been reported from several coastal West African basins. Several records for Gabon: widely found in lower Ogowe and in lower Nyanga (Fermon, pers. obs.). Recently caught in the Komo basin (Fermon, pers. obs.).
