Short description

Usually bluish olive, gray or black on the upper part of the body, becoming white below; dark spots usually scattered along the sides; older males dark in color, the head looking very wide when seen from the top; long barbels surrounding the mouth and the tail deeply forked (Ref. 44091).

Adults inhabit rivers and streams and prefer clean, well oxygenated water (Ref. 9988), but also in ponds and reservoirs (Ref. 10294, 44091). They feed primarily on small fish, crustaceans (e.g. crayfish), clams and snails; also feed on aquatic insects and small mammals (Ref. 9669, 10294, 44091). Marketed fresh, smoked and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Albino form common in the aquarium trade (Ref. 13371).

IUCN Red List Status (Ref. 115185)

Least Concern (LC)

Threat to humans

Potential pest (Ref. 13371)
