Eurasia: Caspian, Black, Azov and Aegean Seas, ascending rivers to spawn. Occurrence in Albania needs confirmation. Introduced in Aral Sea. Artificially propagated (Ref. 6866). Probably extirpated from Aegean Sea and related river basins (Ref. 113969). Appendix III of the Bern Convention (protected fauna).

生物学特性     字汇 (例如 epibenthic)

At the sea, it occurs in coastal and estuarine zones and forages on the bottom mostly on clayey sand and intensively in the middle and upper water layers (Ref. 59043). Found mainly near shore over sand and mud, stays at the bottom during the day and rises to the surface to feed at night. Feeds mainly on fish, also mollusks, crustaceans and worms (Ref. 3193). Spawns in strong-current habitats in main course of large and deep rivers, on stone or gravel bottom. Spawning also takes place on flooded river banks and if gravel bottom is not available, on sand or sandy clay. Juveniles stay in shallow riverine habitats during first summer (Ref. 59043). One of the three most important species for caviar; also utilized fresh and frozen; eaten pan-fried, broiled and baked (Ref. 9988). Overfishing at the sea for meat and caviar will soon cause extinction of the natural populations and their survival can only depend on stocking (Ref. 59043).

主要地发现在沙子与泥上的近岸, 在白天期间停留在底部而且在晚上上升到水表觅食。 主要吃鱼,也捕食软件动物,甲壳动物与蠕虫。 (参考文献 3193) 为鱼子酱的这三个之一最重要的种; 也生鲜利用与冷冻; 吃油锅炸的, 火烤的与烧烤。 (参考文献 9988)
