IdentificationThe catfish genus Ompok La Cepède, 1803, consists of medium-sized silurid fishes found in inland waters throughout South and Southeast Asia. The genus is traditionally diagnosed by the presence of a short dorsal fin with 4 rays, strongly forked caudal fin, subcutaneous eye that is set immediately posterior to the mouth rictus and two patches of palatal teeth (Weber & de Beaufort, 1913). Bornbusch (1995) showed that Ompok, as currently understood, is probably paraphyletic.
