Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1. Diagnosis: adipose fin always absent; head rounded; lower jaw shorter than upper jaw; nasal barbel at least reaching to anterior border of opercle; inner side of pectoral spine feebly serrated; particular coloration characterized by irregularly marbled pattern; caudal and anal fin almost continuous (Ref. 43912).

Confined to lakes and rivers of moderate size; forest species which is often found in small forest waters; mainly carnivorous (Ref. 43912). Oviparous, eggs are unguarded (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 (0.00430 - 0.01402), b=3.05 (2.88 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Assuming fec > 10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).
