Scientists from the Azov-Black Sea branch of VNIRO conduct research on reservoirs of complex purpose in Stavropol Krai

Water bodies of complex purpose (reservoirs) are created by man to solve many problems related to the use of water resources. They are used to generate electricity, irrigate agricultural land, provide sanitary releases, provide drinking and industrial water supply, combat floods, etc. They are also of great importance for fisheries. The organization and management of fisheries on reservoirs plays a major role in providing the population with fresh fish.
 
Water bodies of complex purpose are the most important part of the water fund of the Stavropol Territory. They contribute to the economic and social development of the region due to their multi-purpose use.
 
Last year, specialists from the Krasnodar Department of the Azov-Black Sea branch of the State Research Center of the Russian Federation "All-Russian Research Institute of Fisheries and Oceanography" (VNIRO) conducted monitoring observations on the reservoirs of the region (Krasnoye, Volchye Vorota, Otkaznenskoye, Chograyskoye).
 
The Azov-Black Sea branch of VNIRO constantly conducts comprehensive studies of water bodies, including an assessment of the ecological state of water bodies, determination of commercial stocks of aquatic bioresources, ensures the organization of cage and pond fish farming, and develops business plans taking into account the potential of various types of activities.
 
In 2024, monitoring work was carried out by branch specialists not only on multi-purpose water bodies, but also on the rivers of the Stavropol Territory. The selected water samples were examined to identify various environmental indicators, such as acidity (pH), temperature, oxygen content, salinity, transparency, mineralization and chemical composition. An assessment of the biomass of food organisms in water bodies was also carried out, which is important for understanding the ecosystem of the reservoir. Ichthyological studies were carried out using net fishing and drag nets. The catches were determined by: species and size-mass composition, sex, species ratio in percent. Ichthyological samples were collected for a full biological analysis and age structure.
 
The materials obtained during the expedition work will serve as a basis for developing effective measures aimed at increasing fish productivity and protecting the ecosystem of water bodies, as well as developing fisheries.
 
The Stavropol Territory has all the opportunities to increase the catch of aquatic biological resources in reservoirs of complex purpose. This is facilitated by favorable natural and climatic conditions, a significant fund of freshwater reservoirs, which exceeds 50 thousand hectares.
 
The fishery potential of reservoirs is primarily determined by its natural fish productivity, which primarily depends on the development of the food supply, as well as on the conditions for fish growth.
