Specialists carried out control catches, determined the size-age and species composition of the ichthyofauna, and performed a biological analysis. During the expedition, fisheries scientists also collected material for assessing the habitat: samples of zoobenthos, phyto- and zooplankton.
Three species of fish were noted in the ichthyofauna of Lake Shaitanskoye: silver carp, golden carp, and lake minnow. Crucian carp predominate in quantitative terms.
The fish population of Lake Yanychkovo is more diverse and is represented by seven species: silver crucian carp, golden crucian carp, lake minnow, roach, perch, ruff, ide. The dominant species are two species of crucian carp.
Compared to the previous year, a slight increase in the water level is noted, but overall the level remains low relative to high-water periods.
