Ompok

Ompok is a genus of fishes in the family Siluridae found in lakes and large rivers throughout South and Southeast Asia.

==Taxonomy== The genus is recognized to be paraphyletic. The species of Ompok have been grouped into species groups, such as the Ompok bimaculatus group (i.e. O. bimaculatus, O. malabaricus and O. miostoma), the O. eugeneiatus group (i.e. O. eugeneiatus and O. pinnatus), the O. hypophthalmus group (i.e. O. hypophthalmus, O. rhabdinurus and O. urbaini) and the O. leiacanthus group (O. fumidus, O. jaynei and O. leiacanthus). On the other hand, the monophyly of these species groups is not strong enough to reassign species to other genera.
