Sevruga is a type of sturgeon known for its high-quality caviar. It is primarily found in the Caspian Sea, Black Sea, and Azov Sea. Sevruga sturgeons are smaller than other sturgeon species, typically reaching lengths of about 3 to 4 feet. Their caviar is prized for its small, dark eggs and rich flavor. This fish is an important species in the caviar industry, but it faces threats from overfishing and habitat loss. As a result, Sevruga is listed as endangered in many regions, prompting conservation efforts to protect its populations and habitats.
