ABSTRACT

The current state of size and weight parameters and age structure of silver bream in the upper part of the Volga stretch of the Kuibyshev water reservoir show persistence of a negative trend at the beginning of the current century: a decrease in the size and weight parameters of the silver bream and an increase in the number of younger fish. The current situation can be considered as an indicator of the general negative state of fish resources in the study area.
