Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 22.0, range 18 - ? cm
Max length : 40.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 3722); common length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 3722); 最大体重: 1.0 kg (Ref. 4699)
Inhabits shallow coastal waters and common in brackish waters (Ref. 36880), mostly over mud bottoms in mangrove-lined creeks and lagoons (Ref. 3722); often entering a considerable distance into freshwaters (Ref. 36880). Feeds on aquatic insects, crustaceans, micro-bivalves and detritus (Ref. 36880). Marketed fresh; processed into fishmeal (Ref. 3722).
栖息于沿岸浅水区与常见于半咸淡水域 (参考文献 36880), 大部份在泥底之上在红树林林列的小溪与泻湖中;(参考文献 3722) 时常进入相当多的距离进入淡水。 (参考文献 36880) 吃水生昆虫,甲壳动物,微-二枚贝的与碎屑。 (参考文献 36880) 在市场上销售生鲜地了; 加工成鱼粉了。 (参考文献 3722)
