Highighted items on the list are where Clarias macrocephalus may be found.
Remarks Occurs in shallow, open water and is capable of lying buried in mud for lengthy period if ponds and lakes evaporate during dry seasons (Ref. 9987). Can move out of the water using its extended fins (Ref. 9987). Found in medium to large-sized rivers, stagnant water bodies including sluggish flowing canals and flooded fields of the Mekong (Ref. 12975). Spawns in small streams (Ref. 9987). Feeds on aquatic insects, young shrimps and small fishes (Ref. 6459). In Thailand and Laos, this fish is considered to be better and more nourishing than Clarias batrachus; uncommon in Laos but common in Thailand; thought wrongly as female of Clarias batrachus in Thailand (Ref 2686).
