ECOLOGICAL MONITORING OF THE ICHTHYOFAUNA STATE OF THE CHIRKEI RESERVOIR BEFORE THE PLANNED RECONSTRUCTION OF THE CHIRKEI HPP
The article presents the biological characteristic of the fish population structure and assesses the impact of reconstruction of the Chirkei HPP on the aquatic biological resources and their habitat. All available information on the state of the aquatic biological resources in the reservoir of the Chirkei HPP is used, including scientific and technical information and archival data from field researches. The collection of ichthyological materials was carried out using the hanging net, ichthyoplankton cone net and the fry travois, according to generally accepted ichthyological methods and determinants. It is shown that, in terms of abundance and biomass, the near-dam zone of the Chirkei reservoir is characterized by the predominance of the river perch, bleak, and, to a lesser extent, silver carp, rudd, and Caucasian chub. In general, the reservoir is populated by unproductive fish species, and food supply poorly develops here. It has been established that the comprehensive reconstruction of the Chirkei HPP will not violate the established hydrological and hydrochemical regime and will not damage the aquatic biological resources of the Chirkei reservoir.
