Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 59 - 63; Afterflossenweichstrahlen: 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).

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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00343 - 0.01757), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.59 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).

Preiskategorie (Ref. 80766): Unknown.
