Adults feed on chironomid larvae, oligochaetes and larvae of caddis flies (Ref. 41072). Baikal sturgeon largely inhabit the areas of Lake Baikal's major tributaries: the delta zone of the Selenga River, Proval Bay, Chivyrkuy and Barguzin Bays. The sturgeons migrate widely throughout the whole lake alongside the coastal line, swimming into bays and coves. In former times, the sturgeons caught used to weigh about 125 kg, yet, they grow slowly and mature late. Length above is assumed, needs to be replaced (RF).
