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.
