Africa: widespread throughout the Nilo-Sudan region of Africa, occurring commonly in all major river basins including Senegal, Niger, Volta, Chad (Ref. 81285, 81652) and Nile (Ref. 3636, 28714, 81652). Found almost everywhere in West Africa, except in Gambia (Ref. 81285). Also present in the Congo basin and lakes Albert, Turkana/Rudolph and Tana (Ref. 3636). Several countries report adverse ecological impact after introduction.

生物学     用語集 (例 epibenthic)

Inhabits channels, lakes and irrigation canals (Ref. 28714, 81652). Adults inhabit deep water, while juveniles are found in shallow water (Ref. 81652). Feeds on fish especially clupeids and Alestes (Ref. 13851). Smaller fish also feed on larger crustaceans and insects; juveniles are planktivorous (Ref. 28714). Threatened due to over harvesting (Ref. 58490). No length type given but assumed to be in TL. Maximum reported size of 180.0 cm corresponding to a weight of 164 kg in Lake Albert (Ref. 81285).
