Assessment of fish reproduction in the Kuibyshev reservoir

Employees of the Tatar branch of the Scientific Research Center of the Russian Federation "All-Russian Research Institute of Fisheries and Oceanography" (VNIRO) completed an autumn comprehensive expedition to assess the natural reproduction of commercial fish species in 2026.
 
In the Meshinsky Bay of the Kuibyshev reservoir and in the adjacent water area of the Volga‑A quantitative and qualitative accounting of juvenile fish was carried out using a juvenile travois.
 
During the work, key environmental parameters were recorded daily — temperature and water quality, weather conditions. The water level in the reservoir turned out to be higher than the average annual values and exceeded the indicators of 2025 by 20-25 cm: because of this, numerous shallow waters remained flooded in the fall, which has a beneficial effect on the survival of juveniles.
 
The research covered 17 monitoring stations in a water area of about 94 km2. The catches were dominated by juvenile perch, roach and bleak; for the first time, juveniles of the Czech Republic were found in significant numbers.
 
The results of the autumn survey confirmed the conclusions of the spring‑summer studies: the spawning of commercial fish species in the Kuibyshev reservoir in 2026 was effective.
