Overview

Family : Sturgeons ; Feeds on chironomid larvae, oligochaetes and larvae of caddis flies[1]. Baikal sturgeon largely inhabit the areas of Lake Baikal's major tributaries: the delta zone of the Selenga River , Proval Bay , Chivyrkuy and Barguzin Buys. 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).
