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.
More on author: Pellegrin.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 72 - 89; Anal spines: 0; Anal soft rays: 55 - 71; Vertebrae: 59 - 64. Diagnosis: head oval-shaped in dorsal outline; snout slightly rounded; eyes dorsally located (Ref. 248). Frontal fontanella short and wide/squat (Ref. 248, 57129). Occipital fontanelle rather long and oval-shaped; "dermosphenotic" and supraorbital bones joined; tooth plates small; suprabranchial organ not well developed (Ref. 248). Distance between occipital process and dorsal-fin base short (4.9-9.3% of standard length); pectoral spine serrated on both sides (Ref. 57129). Coloration: live fish as well as preserved specimens very light-coloured: back and sides yellowish brown, belly lighter; some specimens show submarginal blackish marks on vertical fins (Ref. 57129).

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); Occurs in lagoons and coastal rivers (Ref. 248). Feeds on insects, mollusks and crustaceans (Ref. 41457).

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 (0.00416 - 0.01447), b=2.95 (2.79 - 3.11), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.47 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 (22 of 100).
