Actinopteri (ray-finned fishes) > Siluriformes
(Catfish) > Clariidae
Etymology: Clariallabes: Latin, clarias, -a, -um = shining + Greek, allabes, -etos = a fish of the Nile, a kind of lamprey (Ref. 45335). More on author: Pellegrin.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
Africa: endemic to the Ogooué River (Gabon) (Ref. 3820, 81644). Reports from the middle Congo River basin (Ref. 41580, 78218) need confirmation.

Maturity: Lm ?  range ? - ? cm
Max length : 29.0 cm TL male/unsexed; (Ref. 3820)
Morphology | Morphometrics
soft rays: 91. Diagnosis: eyes without free orbital margin; dorsal and anal fins partially fused to caudal fin; dorsal and anal fins about 82% and
67% SL, respectively; skull width about 64% of length; external mandibular barbel half of skull length (Ref. 81644).
In no way predatory, but consumes any material available, including detritus. Decayed plant remains, remains of terrestrial insects, insect larvae and other small invertebrates have been found in the stomach (Ref. 41580, 78218). Found among dead leaves in the forest streams of the inundation zones (Ref. 78218).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±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.).
Vulnerability (Ref. 59153
): Low vulnerability (25 of 100) .
