The sterlet (Huso ruthenus) is a relatively small species of sturgeon from Eurasia native to large rivers that flow into the Black Sea, Azov Sea, and Caspian Sea, as well as rivers in Siberia as far east as Yenisei. Populations migrating between fresh and salt water (anadromous) have been extirpated. It is also known as the sterlet sturgeon.
The sterlet is a small sturgeon species native to major rivers in Eurasia, including those flowing into the Black Sea, Azov Sea, and Caspian Sea, as well as Siberian rivers. Its populations that migrated between freshwater and ocean environments have disappeared, making it an example of how human activity has altered fish populations in these regions.

The sterlet (Huso ruthenus) is a relatively small species of sturgeon from Eurasia native to large rivers that flow into the Black Sea, Azov Sea, and Caspian Sea, as well as rivers in Siberia as far east as Yenisei. Populations migrating between fresh and salt water (anadromous) have been extirpated. It is also known as the sterlet sturgeon.
Due to overfishing (for its flesh, caviar, and isinglass), pollution, and dams, the sterlet has declined throughout its native range and is considered endangered by the IUCN. Restocking projects are ongoing, and it has been introduced to some regions outside its native range, but the latter have generally not become self-sustaining. Today, the majority of the international trade involves sterlets from aquaculture.
