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.
非洲: 在被在包括尼羅河，查德，塞內加爾，佛塔河與剛果的所有的主要河流域出現通常的非洲的衣索比亞區域各處廣泛分佈。在亞歷山大大帝的附近,在湖 Mariout 的半鹹淡水域中呈現。在艾伯特湖， Rudolph 與 Tana 存在。引入後的一些國家報告不利的生態衝擊。

尾鰭圓的。 (參考文獻 4967) 前眼窩而前鰓蓋硬骨被覆了棘; 在鰓蓋的分離邊緣上的一根大的棘。黑的略灰色的-藍色背面, 略灰色的-銀色的在側面上與腹地.(參考文獻 34290)

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).

棲息於峽道，湖與灌溉管。成魚棲息於深水域, 而稚魚被發現於淺水區。捕食魚類尤其鯡魚與 Alestes;(參考文獻 13851) 較小的魚也吃較大的甲殼動物與昆蟲。稚魚是食浮游生物的。 (參考文獻 28714) 受威脅的捕穫之上由於.(參考文獻 58490) 給的沒有長度類型但是可能是的體全長。
