; 新鮮な水; 汽水性の 底生の漂泳性; pH range: 6.0 - 7.5; dH range: ? - 25; potamodromous (Ref. 51243); 深さの範囲 50 - ? m (Ref. 4833). Tropical; 23°C - 28°C (Ref. 2059); 35°N - 8°N
Asia: large rivers of Indian subcontinent and Myanmar (Ganges, Krishna?, Godavari, Irrawaddy). Widely introduced in its geographical range for aquaculture. Reports from Thailand, Malaysia and Indonesia are based on misidentifications.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ?, range 63 - ? cm
Max length : 300 cm SL オス/雌雄の選別がない; (Ref. 2686)
背面の脊椎 (合計) : 2; 背鰭 (合計) : 7; 肛門の骨: 0; 臀鰭: 29 - 32. Eye small, its diameter more than 7 times in head length (in 18 cm long specimens); bright yellow caudal fin in adults; maxillary barbel extends to gill aperture; 23-28 gill rakers on first arch (Ref. 12693).
Facultative air-breathing (Ref. 126274); Found in large rivers and estuaries (Ref. 4833). Occurs in high estuary (freshwater tidal zone) as juveniles, moving to brackish water as sub-adults, and finally as adults to river mouths and inshore areas (Ref. 12693). Longevity given as 10 years (Ref. 2686) but appears too low. Feeds on snails, other mollusks (Ref. 1479) and plants (Ref. 4833). Reared for consumption in Thailand, Cambodia and Vietnam; excellent food fish with very white fine grained sweet flesh (Ref 2686). Marketed fresh (Ref. 12693).
