Pelagic species which lives in schools near the surface of the water (Ref. 35381). Found over soft muddy bottoms. Has no teeth in its jaws but possesses many long gill rakers that are used as a sieve for feeding on planktonic crustaceans like cladocerans, copepods and ostracods (Ref. 35381, 6868). Also feeds on debris, other plankton (Ref. 35381). Appears to follow the plankton's vertical movements during the day. Ovaries start to develop I November when the water level rises. Fractional spawning occurs between February and April. The female lays down 50,000 to 100,000 eggs according to its weight. Juveniles inhabit the lower part of streams in estuaries, adult are found more upstream (Ref. 35381). Marketed fresh and salted.
接近水表面生活在魚群中的大洋性魚種.(參考文獻 35381) 發現在軟泥底部上了。 沒有在它的顎中的齒但是持有因為吃浮游性像水蚤，橈腳類的動物與介形蟲的甲殼動物，許多長的鰓耙那是用作一個篩子.(參考文獻 35381,6868) 也吃殘礫，其他的浮游生物。 (參考文獻 35381) 似乎跟隨浮游生物的垂直運動在白天期間。 卵巢開始發育 I 水位上升的十一月。 少量產卵在二月與四月之間出現。 母魚產下 50,000 到 100,000個卵根據它的重量。 在河口稚魚棲息於溪流的下面部份, 成魚被發現更上游。 (參考文獻 35381) 在市場上銷售生鮮地了與鹽醃的。
