Biology     Glossary (e.g. epibenthic)

Occur in flowing waters of large rivers. Found in the deep-water pools of the Mekong River even during the dry-season (Ref. 43946). Appear to be sedentary with no clear-cut migratory habits (Ref. 43946). Feed on crustaceans and small fishes (Ref. 12693). Loud continuous croaking was observed during the dry season in the deep water areas of the Mekong River which could be linked with spawning behavior (Ref. 43946). Marketed fresh (Ref. 12693). Most desirable and highly priced food fishes in the Mekong region (Ref. 43946). Reaches over a meter in length and at least 18 kg in weight (Ref. 43946).
