Teleostei (teleosts) > Siluriformes (Catfishes) > Clariidae (Airbreathing catfishes)
Etymology: Clarias: Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water; pseudoleiacanthus: Named in reference to its similar external morphology with C. leiacanthus ('pseudo' (= false); 'leios' (smooth); acanthos (spine) (Ref. 49847). Not in Eschmeyer (Ref. 46206).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 66; Anal spines: 0; Anal soft rays: 55 - 57. Short distance between the occipital process and the base of the first dorsal fin ray (4.5-5.6% SL), a very short occipital process length (5.7-8.0% HL), the anterior edge of the pectoral spine smooth and without serrae, and a relatively short anal fin compared to C. nieuhofii with 55-57 rays (Ref. 49847).

Facultative air-breathing (Ref. 126274); Inhabits peat swamps in coastal forest areas (Ref. 49847).

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): 3.4 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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