n October of this year, as part of the implementation of the applied topic "Complex ichthyological and hydrobiological studies of the main freshwater ecosystems of the Volga-Caspian basin in order to assess their receiving capacity" on the reservoirs of the Volga-Don shipping canal (Karpovskoye, Bereslavskoye and Varvarovskoye reservoirs), employees of the Volgograd branch of the State Research Center of the Russian Federation "All-Russian Research Institute of Fisheries and Oceanography" (VNIRO) conducted planned autumn hydrobiological studies to collect material from the main groups of hydrobionts that form the food base of fish (phytoplankton, zooplankton and zoobenthos). The material was collected along an established grid of stations, which included 27 sampling points. During the work, the branch's specialists collected 81 hydrobiological samples. At the same time, measurements of some hydrochemical and hydrological characteristics of water bodies (depth, temperature and transparency of water, oxygen content, electrical conductivity, etc.) were carried out in order to assess anthropogenic factors affecting the functioning of the reservoirs of the Volga-Don Shipping Canal.
The collected material was transferred to the branch for further processing and analysis of the state of the habitat of the local ichthyofauna in the autumn period.
