Adults occur mainly over shallow muddy bottoms in coastal waters. Also enter rivers (Ref. 3479, 6390, 11230). Juveniles found in estuaries. During winter, adults ascend the rivers. They usually form loose schools, although larger fish are more often observed in pairs or singly (Ref. 6390). Feed on prawns and fish (largely members of Mugilidae, Engraulidae, and Sciaenidae) with occasional polychaetes. Frequency of crustaceans to fish in the diet varies seasonally. Larvae (7-30 mm TL) feed mainly on copepods and mysids but also take shrimps and prawn larvae (Ref. 57343). Juveniles (31-60 TL) feed on prawns shrimps and mysids (Ref. 57343). Protandrous hermaphrodites. Marketed fresh, frozen, and dried or salted.

在沿岸水域中主要地遍及泥泞的浅水底部出现。也进入河。 (参考文献 3479,11230) 稚鱼发现于河口了。在冬天期间，成鱼上溯到河。他们通常形成松散的鱼群, 虽然较大的鱼更时常被成对或各别地观察。 (参考文献 6390) 捕食虾，而且鱼 (主要地鲻科鱼类，鳀科与石首鱼科的成员) 偶而有多毛类动物。对在食性中的鱼甲壳动物的频率季节性地改变。仔鱼 (7-30 mm TL) 主要捕食桡脚类的动物，而且糠虾但也吃虾与虾类幼生。 (参考文献 57343) 稚鱼 (31-60 TL) 吃虾蝦與糠蝦。 (參考文獻 57343) 雄性先熟的雌雄同體。在市場上銷售生鮮地了, 冷凍, 與乾燥或鹽醃。

In Australia, fish are males at 24-47 cm FL, hermaphrodites at 25-46 cm FL and females at 28-72 cm FL. On the northeast Queensland coast, most blue threadfin are females by 45-50 cm FL. Hermaphroditic blue threadfin develop fom 1-2-year-old fish, and females first appear as 2-3-year-old individuals (Ref. 28736). Male fish probably commence sex reversal immediately after spawning (ie about April-May) and this condition may persist until after the next spawning period (Ref. 28736). The progression from hermaphrodites to females is complete by the following season. There is little information on the larvae, although nursery areas are known to be lower estuaries, tidal swamps and lagoons, and shallows along the foreshores (Williams 1997).印度-西太平洋: 波斯湾到巴布亚新几内亚与澳洲北部。在亚洲东部 (日本，中国 , 越南) 被 Eleutheronema tetradactylum 取代了。
