Actinopterygii (ray-finned fishes) > Siluriformes (Catfish) > 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: Boulenger.

Africa: Sanaga and Kribi in Cameroon, Ntem in Cameroon and Gabon, Woleu in Gabon, and Ogowe in Gabon (Ref. 81644) and Cameroon (Ref. 51193). Widespread in the lower and middle Congo River basin (Ref. 78218). Also reported from the Wagenia Falls and Lualaba/upper Congo (Ref. 106245). Also in the Chiloango drainage (Ref. 78218), but latter unconfirmed in Ref. 81644.

Short description Morphology | Morphometrics

Dorsal soft rays (total): 72-83; Anal soft rays: 56 - 65; Vertebrae: 59 - 63. Diagnosis: head length 24.5-28.4% SL (Ref. 101841). Head broad, long and flattened; rectangularly outlined in dorsal view (Ref. 248). Interorbital distance 42.6-51.8% HL (Ref. 101841). Tooth plates extremely large (Ref. 248), width of premaxillary tooth plate 32.4-40.0% HL, and of vomerine tooth plate 26.4-36.2% HL (Ref. 101841). Frontal fontanelle somewhat intermediate between `sole-shaped' and `knife-shaped'; occipital fontanelle oval-shaped; pectoral spine straight (Ref. 248). 14 or fewer gill rakers (Ref. 101841), which are short and widely separated (Ref. 248). Supra-branchial organ consists of well-developed arborescent structures but not completely filling the cavity (Ref. 248). Dorsal fin length 60.4-65.6% SL; distance from dorsal to caudal fin 1.6-3.7% SL (Ref. 101841). Colouration: both in life and in preservation colouration is marbled: large irregular black blotches on a pale brown base are present on the back, flanks, dorsal and anal fins, and on upper side of the paired fins; ventrum and lower parts of paired fins are beige, as are the distal parts of unpaired fins; caudal fin bears a series of pale and dark bands (Ref. 248, 101841). Never an irregular pattern of small white spots on body (Ref. 101841).

Biology     Glossary (e.g. epibenthic)

Restricted to equatorial forest and galley forest rivers (Ref. 248). Inhabits smaller rivers, ditches and inundation zones (Ref. 78218). Feeds on fish (Ref. 248, 78218).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00336 - 0.01560), b=2.99 (2.82 - 3.16), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.73 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100) .
Price category (Ref. 80766):   Unknown.
