Ecology of Alosa caspia
 
Main Ref. Whitehead, P.J.P., 1985
Remarks Schooling and migratory. Occurs chiefly in brackishwater, 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.
