Found inshore in summer, but at least some moving into deeper water in winter. Adults are found in near surface waters (Ref. 38984), usually in shallow areas overlying continental shelf, in greatest abundance immediately adjacent to major estuaries (Ref. 4639). Juveniles are also generally pelagic, with smallest size groups farthest up river (Ref. 38986). Form large and very compact schools, both of juveniles and adults. Migrate north - south; also in and out of bays and inlets. Feed by filtering phytoplankton (diatoms (Ref. 5951)) and zooplankton (small crustaceans, annelid worms and detritus (Ref. 5951)). High water temperatures apparently limit breeding. Spawn probably all year; nursery areas in estuaries. Larvae are pelagic (Ref. 38985), probably spend about a month in waters over continental shelf (Ref. 38983), entering estuarine waters at about 10 mm and larger (Ref. 844). Marketed fresh, salted, canned or smoked. Mainly used for production of oil, fertilizer and fishmeal (Ref. 188). Parasites found are isopods, copepod, cestodes and trematodes (Ref. 37032).
在夏天发现于岸边了, 但是至少一些迁进较深的水域冬天时。 成鱼在水表面 (参考文献 38984) 的附近被发现于, 通常在过度地大陆架的水浅的区域, 在最大的丰度中紧邻主要的河口.(参考文献 4639) 稚鱼也通常是大洋性, 鱼群最小溯河最远。 (参考文献 38986) 形成大的与非常紧密的鱼群, 稚鱼与成鱼都有。 回游南北; 也在湾内中来回进出。 藉着滤食浮游植物觅食与浮游动物。 高水温显然地限制繁殖。 整年可能产卵; 在河口的繁殖场。 仔鱼是大洋性的 (参考文献 38985), 大约一个月可能在大陆架 (参考文献 38983) 上的水域中度过, 于大约 10 mm 进入河口的水域与比较大的.(参考文献 844) 在市场上销售新鲜的,盐腌的, 将或者装于罐头烟熏了。 主要地用来了油,肥料与鱼粉的生产。 (参考文献 188) 发现的寄生虫是等足目动物,桡脚类的动物,条虫与吸虫。 (参考文献 37032)
