; 淡水 居于水底的; 河川洄游 (Ref. 51243); 深度上下限 10 - 60 m (Ref. 34290). 熱帶; 27°N - 7°S
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。

Numerous villiform teeth present in jaws, on palate (Ref. 81285, 81652) and vomer (Ref. 81652). Preorbital/lachrymal (Ref. 4967, 81652) and preopercle (Ref. 4967, 81285, 81652) denticulate. Strong, prominent opercular spine present (Ref. 4967, 81285, 81652) on free edge of opercle, and a smaller one dorsal to it (Ref. 81652). Dorsal fin divided by a deep notch into anterior spiny and posterior soft-rayed sections; anal fin with 3 spines; pelvics with a spine and situated close to the pectorals (Ref. 28714).

Coloration: body uniformly silvery (Ref. 81285) or dark greyish-blue dorsally, greyish-silver on flank and ventrally (Ref. 34290, 81652). Fins greyish; interior of eye conspicuously yellowish (Ref. 81285). Juveniles brownish with lighter marbling (Ref. 81285) on head and flanks (Ref. 81652).
尾鳍圆的。 (参考文献 4967) 前眼窝而前鳃盖硬骨被覆了棘; 在鳃盖的分离边缘上的一根大的棘。 黑的略灰色的-蓝色背面, 略灰色的-银色的在侧面上与腹地.(参考文献 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).
栖息于峡道，湖与灌溉管。 成鱼栖息于深水域, 而稚鱼被发现于浅水区。 吃鱼尤其鲱鱼与 Alestes;(参考文献 13851) 较小的鱼也吃较大的甲壳动物与昆虫。 稚鱼是食浮游生物的。 (参考文献 28714)
