Épines dorsales (Total): 7 - 8; Rayons mous dorsaux (Total): 8-14; Épines anales 3; Rayons mous anaux: 7 - 9. Diagnosis: mouth large and protrusible, lower jaw (slightly) prominent (Ref. 81285, 81652). 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). Caudal fin rounded (Ref. 4967, 81285, 81652). Scales ctenoid, 54-74 along lateral line, followed by 6-8 pored scales on caudal-fin base; ceratobranchial (lower limb) of first gill arch with 12-14 gill rakers (Ref. 81285). 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).

Biologie     Glossaire (ex. epibenthic)

Inhabits channels, lakes and irrigation canals; 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).
