; 淡水; 半咸淡水 底中水层性; pH range: 6.0 - 7.5; dH range: ? - 25; 河川洄游 (Ref. 51243); 深度上下限 50 - ? m (Ref. 4833). 热带; 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.
亚洲: 印度次大陆与缅甸的大河 (恒河, 克里希纳河?, Godavari, 依洛瓦底江). 对于水产业广泛地在它的地理分布中引入。 来自泰国的报告, 马来西亚与印度尼西亚是以误鉴为依据。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm ?, range 63 - ? cm
Max length : 300 cm SL 雄鱼/尚未辨别雌雄; (Ref. 2686)
背棘 (总数) : 2; 背的软条 (总数) : 7; 臀棘: 0; 臀鳍软条: 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).
眼小的, 它的直径超过 7 倍头长;(18 公分长标本) 当成鱼时的鲜黄色的尾鳍; 上颌骨触须延伸到鳃孔; 在第一鳃弓上的 23-28个鳃耙.(参考文献 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).
发现于大河与河口了。 (参考文献 4833) 稚鱼时出现于高的河口 (淡水潮间带), 亚成鱼时移动到半淡咸水, 与最后当成鱼时到河口与沿海地区区域.(参考文献 12693) 寿命被估为 10 年 (参考文献 2686) 但是显得太低的。 吃蜗牛，其他的软件动物 (参考文献 1479) 与植物。 (参考文献 4833) 在泰国，柬埔寨与越南为消费后面了; 用很白细的有木纹的甜肉 (参考文献 2686) 的优良食用鱼. 在市场上销售生鲜地了。 (参考文献 12693)
