Abstract

The results of long-term observations on changes in the relative body conditions of burbot (Lota lota L.) in the Lower Ob basin during the open channel period (June–September) are analyzed. Statistically significant strong positive dependence of the hepatosomatic index of spawners on the maximum flood level is revealed. An equation predicting the value of the hepatosomatic index of spawners from instrumentally measurable environmental parameters is constructed.
