Аннотация: Abstract—Cyanobacteria blooms occurred in the pond in early August; Microcystis aeruginosa was constantlypresent in the plankton. Its biomass reached its peak of 24.1–28.6 mg/L in mid-August. The proportion of individualcells (4 µm in size) and colonies up to 50 µm in size in the M. aeruginosa biomass increased to 68–85%. In lateAugust, the proportion of 50–100-µm fraction did not exceed 5–7%. The proportion of a larger fraction >100 µmdecreased from 24 to 8%. Rotifers, represented by 14 taxonomic units recorded in the plankton, dominated in thewater body. The abundance of Rotifers reached 51–96% of that of zooplankton. Dominating in abundance wasKeratella cochlearis cochlearis. It accounted for 44 to 86% of rotifer population, and its abundance varied from500 to 2000 ind./L. The rotifer abundance during the M. Aeruginosa bloom period reached its highest of 4.5 thous.ind./L and at the end of this period decreased to 580 ind./L. In the high-trophicity pond, rotifers play the leadingrole in the water body trophodynamics.Keywords: highly trophic pond, zooplankton, planktivorous fish, rotifers, cyanobacteria, inorganic phosphorus,chlorophyll-aDOI: 10.1134/S1070363224130073
