Identification	The 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. O. siluroides is often incorrectly identified as the Indian species, O. bimaculatus. O. siluroides is a Southeast Asian species which has a rounder head and a mottled brown colouration, while O. bimaculatus is silvery and has a sharper head.
Sexing	Males are more slender and have strong serrations on the posterior edge of the pectoral spine (females lack these serrations).
