Distribución Países | Áreas FAO | Ecosistemas | Ocurrencias, apariciones | Point map | Introducciones | Faunafri

Africa: lower, middle and upper Congo River basin, including Pool Malebo (= Stanley Pool); Ogooué and Nyanga basins in Gabon; Ntem-Campo, Nyong and Lokoundje basins in Cameroon (Ref. 43912). Also in the Mitemboni River (Gabon-Equatorial Guinea border) and lower Nkomi River basin (Gabon)(Ref. 81643). Reports from the Lali River (upper Kouilou basin) in Republic of Congo or from the Chad basin are based on misidentified specimens; presence in the Ruzisi unlikely, based on a single specimen that is probably mislabelled (Ref. 43912).

Short description Morfología | Morfometría

Espinas dorsales (total): 1. Diagnosis: adipose fin present (Ref. 43912, 81643) and fully developed (Ref. 81643). Anterior nostrils closer to each other than the posterior pair; nasal barbel not reaching beyond the posterior border of the eye; inner side of pectoral spine weakly serrated; snout reaching beyond lower jaw; head rounded (Ref. 43912, 81643).

Biología     Glosario (por ej. epibenthic)

Omnivorous or predominantly carnivorous, feeding on fruits, leaves, grains, insect larvae and nymphs, and small fish; very voracious; juveniles found in floodplains during the rainy season, often hidden under floating trunks of trees which seems a favorite place for juvenile Schilbe and numerous other fish larvae; active swimmer, especially during the night, probably resting near the bottom during daytime (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Important species in fishery terms (Ref. 78218). Flesh of this fish very tasty, its price rather elevated (Ref. 43912).
