Sphaeriida of several reservoirs of the Vitebsk region

Assessed the species diversity of the Sphaeriidae family in several reservoirs of the Vitebsk region. In 2023, bivalve mollusks were collected from lakes Sosno, Polonskoye, Bernskoye, and three ponds. The collection was carried out using a bottom scraper to study the benthos. Species were identified in the laboratory of the Palace of Children and Youth using modern identifiers. Species richness was calculated for each reservoir using the Menkhinik method. It was found that Lake Sosno and the pond on Krupskaya Street are home to the maximum number of mollusk species of the studied group.
