Short description

Dorsal spines (total): 0; Anal spines: 0. Body `shad-like', usually rather deep and compressed. Total gill rakers 50 to 180, long and thin, distinctly longer than filaments. Teeth poorly developed in jaws, sometimes barely detectable. A black spot posterior to gill opening and occasionally further black spots on flank in some cases.

Schooling and migratory. Occurs chiefly in brackish water, but enters freshwaters to spawn. Depending on the subspecies, some are semi-anadromous and spawn in fresh or slightly saline waters, mainly in the lower reaches, whereas others are practically marine and spawn in brackish or even fully saline oceanic waters. One of the most warm-loving Alosa of the Caspian. Feeds on plankton. Only A. a. caspia of the Caspian Sea is of commercial importance. 10 subspecies known.
