Schools in the open sea, not approaching shores. Occurs mainly in the south in winter, migrating to the middle parts of the sea in spring and returning south in November-December. Found in upper layers in March-April, but descends to 16 to 32 m in summer and autumn. Feeds mainly on copepods, also pelagic mysids and small fishes. Breeds in January-September intermittently in the open sea. Stocks said to be depleted in southern part of Caspian Sea.
在开放海域内形成鱼群, 不接近海岸。 主要生活在那南方在被在春天洄游至海洋的中央部份和在十一月到十二月回到南方的冬天。 发现于在三月到四月的上层了, 但是在夏天与秋天对 16 到 32 公尺下降。 主要吃桡脚类的动物, 也大洋性的糠虾与小鱼。 在开放海域中间歇地繁殖于一月到九月。 分枝在里海的南部中据说被耗尽了。
