Abstract
The data on catches of sterlet in the Volga River and on seasonal changes in the age of starlet are presented. The relationship of running males and females who commit their spawning migration is described. It is noted that both running and downstream-migrant manufacturers are met in catches during the season of the study. This circumstance is very important in the organization of sterlet manufacturers catching for fishery. Procurement of the sterlet for reproduction should be carried out throughout the whole season (April – October). Females in the Volga River spawn for the first time in 4 years, males – at 3 years.
