Highighted items on the list are where Clarias batrachus may be found.
Remarks Inhabits swamps, ponds, ditches, rice paddies, and pools left in low spots after rivers have been in flood (Ref. 2854). Usually confined to stagnant, muddy water (Ref. 1479). Found in medium to large-sized rivers, flooded fields and stagnant water bodies including sluggish flowing canals (Ref. 12975). Undertakes lateral migrations from the Mekong mainstream, or other permanent water bodies, to flooded areas during the flood season and returns to the permanent water bodies at the onset of the dry season (Ref. 37770). Can live out of water for quite sometime and move short distances over land (Ref. 4833). Can walk and leave the water to migrate to other water bodies using its auxiliary breathing organs. The Lao use this fish as lap pa or ponne pa. Feeds on insect larvae, earthworms, shells, shrimps, small fish, aquatic plants and debris (Ref. 6459). Feeds mainly on insects (Ref. 13497).
