Comments: Introduced to Lake Victoria to feed on abundant but unexploited small size haplochromines, to convert them into larger table fish (Ref. 7270). Introduction to Lake Victoria virtually eliminated numerous unique cichlids in the area and has been the subject of many debates (Ref. 1739).Used to be present also in satellite lakes Bisina (stocked in the early 1970s) and Nawampasa (following extensive flooding), but surveys in 2009 and 2010 did not uncover any specimens (Ref. 125996).

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.

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 7 - 8; Rückenflossenweichstrahlen (insgesamt) : 8 - 14; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 7 - 9. Diagnosis: mouth large and protrusible (Ref. 28714, 81285, 81652), 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). 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). 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     Fachlexikon (Englisch) (z.B. 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).
