Macrozoobenthos of Lake Saikul as an indicator of freshwater ecosystem stability

The article presents the results of a study of macrozoobenthos of Lake Saykul as an indicator of freshwater ecosystem stability. Macrozoobenthos is considered as a key bioindicator reflecting water quality and the degree of anthropogenic impact. During the research, a seasonal analysis of the species composition, abundance and biomass of benthic invertebrates was carried out. The presence of 41 species belonging to various taxonomic groups was established, among which mollusks and chironomid larvae play a significant role.
