Asia: Mekong, Bangpakong, and Chao Phraya basins.
初回成熟時の長さ / サイズ / 重さ / 年齢
成熟: Lm ?, range 37 - ? cm
Max length : 120 cm SL オス/雌雄の選別がない; (Ref. 30857)
臀鰭: 25 - 30. Dorsum dull grey with pale green iridescence; maxillary band of teeth forms a continuous row with no break in midline (Ref. 12693). Snout protruding with upper jaw tooth bands partly exposed when mouth is closed; large median vomerine tooth plate (Ref. 43281).
Body shape (shape guide): elongated.
Facultative air-breathing (Ref. 126274); Adults occur in large rivers (Ref. 12693) and enters flooded forests (Ref. 9497). They are found in rapids and in deep slow reaches (Ref. 37771). Juveniles feed on prawns and insects; subadults and adults on prawns, insects and particularly mollusks which are more predominant in stomach contents than in any other Pangasius species (Ref. 7432) and on plants (Ref. 9497). They migrate into the middle Mekong along the Thai-Lao border as water levels and turbidity begin to increase. Mature individuals reproduce early in the flood season and juveniles of 6 to 7 cm are taken by late June (Ref. 12693). Marketed fresh (Ref. 12693).
