Biology

Occurs mainly in quiet waters, lakes and pools but may also occur in fast flowing rivers and in rapids (Ref. 248). Widely tolerant of extreme environmental conditions. The presence of an accessory breathing organ enables this species to breath air when very active or under very dry conditions. Remains in the muddy substrates of ponds and occasionally gulp air through the mouth (Ref. 6465). Can leave the water at night using its strong pectoral fins and spines in search of land-based food or can move into the breeding areas through very shallow pathways (Ref. 6868). A bottom feeder which occasionally feeds at the surface (Ref. 248). Forages at night on a wide variety of prey (Ref. 6868). Feeds on insects, plankton, invertebrates and fish but also takes young birds, rotting flesh and plants (Ref. 6465). Migrates to rivers and temporary streams to spawn (Ref. 34291). Also caught with dragnets. During intra-specific aggressive interactions, this species was noted to generate electric organ discharges that were monophasic, head-positive and lasting from 5-260 ms (Ref. 10479). Known as sharptooth catfish in aquaculture, a highly recommended food fish in Africa (Ref. 52863). Marketed fresh and frozen; eaten broiled, fried and baked (Ref. 9987).
