Dorsal fin with 12-14 1/2 branched rays; lower profile of head conspicuously arched; short dorsal fin with anterior branched rays shorter than head; 12-16 predorsal scales ; snout without lateral lobe (Ref. 43281).
背鳍有 12-141/2个分支条; 头部的低轮廓显着弓形; 短背鳍有前面的分支条短于头部; 12-16个前背的鳞片 ; 没有侧叶的吻.(参考文献 43281)
Adults inhabit rivers (Ref. 4832). A diurnal species and usually solitary. They burrow occasionally. Feed on plants. Spawning season generally coincides with the southwest monsoon. Spawning occurs in flooded rivers. Fecundity varies from 226,000 to 2,794,000 depending upon the length and weight of the fish and weight of the ovary. Widely introduced outside its native range for stocking reservoirs and aquaculture. Utilized fresh (Ref. 9987).
栖息于河。 (参考文献 4832) 一个日行性种与通常独居性的。 偶然地掘洞穴。 吃植物。 通常产卵季节与西南季风一致。 在被水淹没的河产卵。 孕卵数从 226,000 改变到 2,794,000 仰赖长度与鱼与卵巢的重量的重量。 广泛地在它的原产地的外边引入育种使用水库与水产业。 生鲜使用.(参考文献 9987)

Spawns in middle reaches of rivers, where flood water spreads in more or less limpid shallows over fertile flats, well above tidal reaches; also in reservoirs and bundh-type tanks. 亞洲: 巴基斯坦，印度，孟加拉，緬甸與尼泊爾。

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00729 - 0.01140), b=3.03 (2.99 - 3.07), in cm total length, based on LWR estimates for this species (Ref.
93245).
营养阶层 (Ref.
69278): 2.2 ±0.12 se; based on food items.
Generation time: 4.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
