Etymology: Ompok: It is a bad reproduction of a Malayam fish name as limpok/ompok (Ref. 45335).
Eponymy: Dr Achille Joseph Urbain (1884–1957) was a French biologist, microbiologist and immunologist. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 4; Anal spines: 0; Anal soft rays: 65 - 71; Vertebrae: 47 - 52. Head width 11.7-13.6% SL; caudal peduncle depth 5.2-5.9% SL; anal fin rays 65-71; and vertebrae 47-52 (Ref. 52514).

Occurs most frequently in large slow-flowing rivers and lakes. Migrates into inundated forest during periods of high water, where it can be found around submerged woody vegetation. Feeds on fishes and crustaceans (Ref. 52514).

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=0.00562 (0.00279 - 0.01132), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
