Short description Morphology | Morphometrics

Dorsal soft rays (total): 59-63; Anal soft rays: 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).

Biology     Glossary (e.g. epibenthic)

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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00336 - 0.01560), b=2.99 (2.82 - 3.16), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.59 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100) .
Price category (Ref. 80766):   Unknown.
