The species composition of macroinvertebrates and water quality assessment using the macrozoobenthos organisms of the Izhevsk reservoir

[摘要] The species composition of macroinvertebrates of the Izhevsk Reservoir was specified. Changes in the taxonomic structure of macroinvertebrates on different biotopes were shown. A significant simplification of the bottom-dwelling communities' structures of the rivers Izh and Pazelinka in the deep-water part and increase in species richness at the mouth area, overgrown with macrophytes, was identified. A total of 414 species and taxons of higher macrozoobenthos rank were identified. According to the results of bioindication the upstream and middle part of the Izh reservoir can be classified as a β-mezosaprobic area.
