Diagnosis: Body fairly deep and compressed, belly with distinct keel of scutes; top of head with numerous fronto-parietal striae; upper jaw with median notch; gillrakers about 100 to 175, those on inner arches distinctly curled; outer row of gill filaments on first arch not more than half length of gillrakers; a series of small triangular scales above axil of pectoral fin; hind part of body scales perforated (Ref. 188).

頭頂有很多的額頂骨陷紋; 上頜有中央的凹槽。 鰓耙大約 100 到 175, 在內弓上的那些明顯地捲曲; 在第一鰓弓上的鰓絲的外部列不超過鰓耙的一半長度。 在胸鰭的葉腋上面的一系列的小三角形的鱗片; 身體鱗片的後部部份穿孔的。 在鰓裂後面的一個黑色的斑點; 通常 10 沿著側面。
Found in coastal waters (Ref. 3107, 30573); marine, pelagic, but entering estuaries and able to tolerate quite low salinities (7 ppt) (Ref. 188). Feeds chiefly on phytoplankton, mainly diatoms, also dinoflagellates, but also copepods, molluscan and crustacean larvae, prawns, amphipods and polychaetes (Ref. 188). Spawns, at least in Godavari estuary, around February (Ref. 188). Marketed fresh, dried, dried-salted and boiled. Made into fish balls.
發現於沿岸水域 (參考文獻 30573), 進入河口而且能容忍相當低的鹽度 (7個 ppt) 。 主要捕食浮游植物 (主要地矽藻 , 也吃腰鞭毛蟲) ，也吃橈足類， molluscan 與甲殼類幼生，蝦，片腳類動物與多毛類動物。 產卵 (至少在 Godavari 河口) 二月左右。 (參考文獻 188) 在市場上銷售生鮮地,乾製了, 乾燥鹽醃與煮沸的。 製成了魚丸。 發現於下面湄公河的整個流域主流了。 (參考文獻 36667)
