Biology
A fluvial fish which inhabits rivers and their tributaries. Chiefly potamodromous. Like other sturgeons, it aggregates in bottom holes in winter and exhibits little activity. In spring, when ice breaks, it rises from the bottom holes and moves upstream for spawning. For spawning, the fish choose the main channel of the river, where the current is fast and the bottom is covered with gravel.
