Short description Claves de identificación | Morfología | Morfometría

Radios blandos dorsales (total) : 59 - 63; Radios blandos anales: 42 - 46. Nude body without scale, sticky. Yellowish brown or dark gray, white and gray stomach. Lateral white dots on the sides (Ref. 40531). Sometimes confused with the channel catfish, but Clarias fuscus can be differentiated by its rounded tail and long dorsal and anal fins (Ref. 44091).

Biología     Glosario (por ej. epibenthic)

Facultative air-breathing (Ref. 126274); Adults occur in streams, ponds, ditches and reservoirs. They prefer deeper pools and tend to hide under thick mats of vegetation; are nocturnal feeders foraging on small fishes, worms, crustaceans and insects (Ref. 44091). Benthic (Ref. 58302). Oviparous (Ref. 205).
