The Siberian sturgeon (Acipenser baerii) is a freshwater fish of the family Acipenseridae that grows up to 200 cm.
Description
The Siberian sturgeon is a large freshwater sturgeon of the family Acipenseridae reaching about 2 metres. It has a pointed snout with smooth barbels beneath it to probe the bottom, and like all sturgeons bears five lengthwise rows of bony plates instead of ordinary scales. Unlike many relatives it is a pure freshwater fish: it lives in the great Siberian rivers Ob, Yenisei and Lena and in Lake Baikal, and migrates upstream within fresh water to spawn. On the bottom it eats insect larvae, worms, molluscs and small fish. It grows slowly and matures late. For its flesh and caviar it is widely farmed, but wild populations are Endangered (EN) through overfishing and dams.
