It is native to the waters around Sakhalin Island and the adjacent Russian Far East. Typically growing up to 78 inches in length, this species migrates from the sea to spawn in freshwater rivers, feeding on invertebrates and small fish. It is considered vulnerable due to habitat loss and overfishing.
