    Biology


    Occurs in large upland rivers. Common in areas with rocky bottoms and irregular depths (Ref. 12693). Apparently does not migrate but reproduces locally and enters the flooded forest during high water in July-October (Ref. 38441). Feeds on insects, prawns, fish (Ref. 33813) and crabs (Ref. 38441). Marketed fresh (Ref. 12693). Maximum weight reported for an individual caught in Mae Klong River, Thailand, reached 86 kg (J-F. Helias, pers.comm., 07/2002; see photo Hewyc_u0.jpg).
