Stenodus Leucichthys


a fish of the salmon family. The body length is up to 120 cm and the weight to 14 kg. Females reach sexual maturity in the sixth or seventh year of life; males, in the fifth or sixth year. The fish live in the Caspian Sea and enter into the Volga, Kama, and occasionally Ural rivers to spawn. They are a valuable commercial fish. The number of fish has decreased sharply as a result of the construction of a number of hydroelectric projects that create barriers to the entry of the fish into the river to propagate. The subspecies Stenodus leucicthys nelma is found in the basin of the Arctic Ocean.
