生态学
; 淡水; 半咸淡水 大洋性; 非产卵性溯降河的 (Ref. 51243). 亞熱帶的; 30°N - 6°N, 84°E - 100°E
Asia: Indian fresh and brackish waters (Ganges system, from Diamond Harbor on the Hooghly to as far up as Allahabad on the Ganges, perhaps further; also rivers and estuaries of Orissa). Reported from Bangladesh and Myanmar (Ref. 45255).
亞洲: 印度的淡水與半鹹淡的水域 (恆河流域, 從 Hooghly 之上的鑽石港灣在恒河上向上遠達 Allahabad, 也許更進一步; 也奧里薩的河與河口). 記錄來自孟加拉與緬甸了。 (參考文獻 45255)
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 14.5 range ? - ? cm
Max length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 189)
背棘 (总数) : 0; 臀棘: 0; 臀鳍软条: 66 - 78. Belly with 21 or 22 keeled scutes from isthmus to anus. Lower gill rakers with the serrae even or becoming clumped in some specimens. Pectoral filament long, reaching to base of 15th to 39th anal fin ray. Anal fin with upper caudal lobe truncated, shorter than lower. Pectoral fins hyaline, but dark in fishes over 13.6 cm SL.
腹面有 21 或 22个从峡部到肛门的有龙骨的鳞甲。 甚至下鳃耙有锯齿，否则变成在一些标本中形成一丛。 胸的丝状突起长的, 延伸到第 15 到第 39个臀鳍鳍条的基底。 臀鳍有上尾部的叶截形的, 短于低的。 胸鳍透明的, 但是黑的在超过 13.6 公分 SL 的鱼中。
A riverine species, but also found in estuaries and presumably tolerating some salinity. Adults feed mainly on mysids and small prawns (reduced feeding during breeding), juveniles mainly on copepods. Possibly breeds throughout the year, with peaks in October and November (Hooghly at Barrackpore) or March-May (Ganges at Allahabad). Its large size makes it an attractive foodfish.
一个河栖性鱼种, 也发现于河口与可能容忍一些盐度。 成鱼主要捕食糠虾与小的虾 (在繁殖的时候缩小的进食) ，稚鱼主要捕食桡足类。 可能地繁殖全年度, 颠峰期在十月与十一月 (Hooghly 在 Barrackpore) 或三月-五月.(恒河在 Allahabad) 它的巨大的体型使它成为一个吸引人的食用鱼。
