Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

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.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 65 - 79; Anal soft rays: 57 - 64; Vertebrae: 52 - 55. Pectoral fin spine serrated on both inner and outer sides (Ref. 34290). Head oval-shaped in dorsal outline; snout short and slightly rounded; eyes more dorsally located. Frontal fontanelle long and narrow (`knife-shaped'); occipital fontanelle long and oval-shaped. Supraorbital and `dermospenoticum' joined. Tooth plates relatively small. gill rakers long, slender and distantly set. Suprabranchial organ well developed. Openings of the secondary sensory canals regularly arranged on flanks.

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); Occurs in rivers, streams, swamps and lakes. Occurs along muddy shores and in papyrus swamps in Lake Victoria; also in ponds of rice schemes (Ref. 36900), side-arms of larger waters (Ref. 78218) and in mountainous streams (Ref. 27292). Mainly insectivorous (Ref. 248), a wide variety of insect larvae and crustaceans (Ref. 78218). Also small fish are taken (Ref. 27292). Might undertake mass migrations up rivers and streams, maybe to spawn (Ref. 27292).

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):  3.2   ±0.40 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
