The starry sturgeon (Huso stellatus),[6] also known as the stellate sturgeon or sevruga (Drakul, Persian: اوزون برون, and Turkish: Uzun Burun, lit. 'long nosed'), is a species of sturgeon. It is native to the Black, Azov, Caspian and Aegean sea basins, but it has been extirpated from the last and it is predicted that the remaining natural population will follow soon due to overfishing.[1]
The starry sturgeon is an anadromous species, which migrates up rivers to spawn.[7]
It is considered critically endangered by the IUCN and international trade in this species (including its caviar) is restricted by CITES.[1]
Taxonomy
Prior to 2025, it was placed in the genus Acipenser, but this placement was found to be paraphyletic, and it is more accurately placed in the genus Huso.[6][8]
Description
The starry sturgeon reaches about 220 cm (7.2 ft) in length and weighs up to 80 kg (180 lb).[7] It is a slim-bodied fish easily distinguished from other sturgeons by its long, thin and straight snout. A row of five small barbels lies closer to the mouth than to the tip of the snout. The scales on the lateral line number between thirty and forty and these features distinguish this fish from the Russian sturgeon (H. gueldenstaedtii). Its general colouring is dark greyish-green or brown with a pale underside. The scales on the lateral line are pale.[9] The maximum reported age for this species is 27 years.[7]
Biology
The starry sturgeon is a harmless species that feeds on fish, worms, crustaceans and mollusks.[7] It lies on the bottom during the day and feeds mostly at night. This fish is anadromous and moves upriver into shallow waters to spawn.[9]

Conservation
The species is believed to have undergone a loss of 95 percent of its population in three generations. Illegal fishing is a major threat to the survival of this species.[1]
