Feeds chiefly on small fishes, less frequently on insect larvae and crustaceans (the latter though being the main food for A. kessleri volgensis). Migrates northward in spring (March or April, but sometimes as early as February or even January), apparently mainly along the western shore. Mass migration of large individuals into the Volga starts when the water temperature is about 9° C, reaching a peak at temperatures of 12°-15° C, and ceases at about 22° C (Ref. 10432). Spawning occurs from mid-May to August in rivers, some in the lower reaches or even delta, others as far as 500 km upstream. The young descends in late summer and autumn. Two subspecies known. The flesh of A. k. kessleri is said to be the tastiest of all Caspian clupeids owing to its high fat content, averaging 18.9% by weight before the spawning period, diminishing to about 1.5% after spawning (Ref. 10432).
