Abstract
Compared to the data collected in 2016, pronounced changes in the malacofauna inhabiting the Shershnevskoye Reservoir (city of Chelyabinsk) were discovered in August 2022 at inshore sampling stations near the dam. Mollusks of the family Sphaeriidae have disappeared from the community of bivalves. The species Dreissena polymorpha (Pallas, 1771) of the family Dreissenidae predominated the malacofauna in 2022. Analysis of the size and age structure of the D. polymorpha population showed that the maximum age of mollusks was 5 years. The collected data indicate that D. polymorpha has successfully invaded the Shershnevskoye Reservoir in the period since 2016 and naturalized there.
