Description synthétique Clés d'identification | Morphologie | Morphométrie

Distinguished from Silurus glanis by the following unique characters: one pair of mental barbels; and anal fin with 66-75½ rays (Ref. 59043).

Inhabits lowland rivers and nutrient-rich lakes. Feeds at night mainly on fish. Also preys on crustaceans, gastropods, insects, amphibians and aquatic snakes. Spawns in pairs. Attains first sexual maturity at 2-3 years of age (Ref. 59043).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

Males defend small territories at the spawning sites and construct nests made of plant materials. They dig shallow depressions or clean spawnng substrate, at 2-3 m depth. They guard nests until larvae emerge. Spawns in pairs. Eggs hatch in 5 days (Ref. 59043).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00278 - 0.01137), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (tmax=10; K=0.099-0.100;).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).
