Abstract
The results of studies of macrozoobenthos and pleustonic aquatic invertebrates complexes of the Viliya River have been considered in the article. 92 species and forms related to 3 types of aquatic animals which are Mollusca – 15 species and forms; Annelida – 2 and Arthropoda –75 have been detected. The analysis of the species composition has shown in all studied sites that the species richness was within the range of 29–30 species. At the place of wastewater discharge from the town of Vileika, a species richness decrease and the number of Diptera and Oligochaeta increase has been observed. The relatively high number of species with rheophilic and oxyphilic properties such as representatives of the Plecoptera, Ephemeroptera, and Trichoptera orders groups indicates a fairly high water quality in the investigated sites of the Viliya River. Rare and protected for Belarus and Europe.species have been found.
