Caspian sturgeons historically spawned in the Volga, Ural, Kura, Terek and Sulak Rivers, but dams have been constructed except along the lower and middle Ural and limit migration and dispersal. It is found primarily in the Caspian and Black Sea basins, and formerly in the Adriatic Sea.

Beluga caviar has long been scarce and expensive and its endangered status has made its caviar even more expensive throughout the world. 6472). huso dauricus. Ultrasonography showed that the masses had different patterns. [18], In brackish environments of the Ponto-Caspian basin, the genera Alosa, Aspius and Engraulis are the preferred prey. Pirogovskii, M.I., L.I. En Bester er en kunstigt avlet hybrid mellem en belugastør og en sterlet (Huso huso x Acipenser ruthenus). [6], Like most sturgeons, the beluga is anadromous, migrating upstream in rivers to spawn on clean, hard substrate, which offers both support and cover to their sticky/adhesive eggs. The largest accepted record is of a female taken in 1827 in the Volga estuary at 1,571 kg (3,463 lb) and 7.2 m (23 ft 7 in). Feasibility of collagens obtained from bester sturgeon Huso huso × Acipenser ruthenus for industrial use. [5] Heavily fished for the female's valuable roe, known as beluga caviar, wild populations have been greatly reduced by overfishing and poaching. [9] Among sturgeons, only the closely related Kaluga (Huso dauricus) can attain similar size, with a maximum weight of 1,000 kg (2,200 lb). The female lays her eggs on gravel from 4 to 40 m (13 to 131 ft) underwater. Undertakes upriver migration to spawn. and other sturgeons for the biggest.

The barbels are laterally compressed with foliate appendages, arranged in two pairs, originating midway or closer to the mouth than the tip of the snout.[6]. Approximately 5300 hybrid sturgeons with an average body weight of 600– 800 g were mixed farmed in 3 round tankers measuring 3 m in [19] In both sexes, they will go to spawn every 4 to 7 years. [20] The flesh of the beluga, though, is not particularly renowned but is a hearty white meat similar to that of swordfish.

The beluga sturgeon, Huso huso, is endemic to the Ponto-Caspian Sea region that includes the Caspian Sea (the largest inland body of water in the world) as well as the Sea of Azov and the Black Sea (Bemis & Kynard 1997, Berg 1948).
