Actinopterygii (ray-finned fishes) > Siluriformes
(Catfish) > Clariidae
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.
Environment / Climate / Range
Freshwater; demersal. Tropical, preferred ?
Africa: Luapula-Moero system (upper Congo River basin), upper Kasai drainage (middle Congo River basin), Kafue River, upper Zambezi system, Cunene River and Okavango (Ref. 248).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 41.0 cm SL male/unsexed; (Ref. 7248)
soft rays: 56 - 63;
Vertebrae: 58 - 61. Characterized by its lateral line which appears as a thick white band; barbels extremely short. Head long, broad and flattened. Frontal fontanelle long and extremely narrow. Occipital fontanelle rather small. The `dermosphenotic' and supraorbital bones are separated. Tooth plate extremely broad. Pectoral spine straight and robust. Suprabranchial organ well developed but not completely filling the chamber.
Occurs in well-vegetated sluggish river channels and floodplain lagoons. Breeds during the summer rainy season (Ref. 7248). Eats invertebrates and, when older, other fishes (Ref. 7248, 78218).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00431 - 0.01274), b=3.00 (2.85 - 3.15), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.5 ±0.6 se; Based on diet studies.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (41 of 100) .
