The paper deals with the analysis of bioindicator opportunities of hydrobionts of various systematic categories that helps to assess and forecast anthropogenic pollution of the Belaya River (the top and average currents) during environmental monitoring of natural waters of the Republic of Bashkortostan. Hydrobionts were collected and the occurrence analysis (in unit shares) of 30 species of invertebrate animals from groups Pyramidelloida, Littorinimorpha, Pulmonata, Plecoptera, Ephemeroptera, Trichoptera and 12 species of the highest water vegetation was carried out from 2005 to 2017 in regions of 10 state water posts on the Belaya River. The data from annual State reports on the average annual content of compounds of manganese, nickel and iron, oil products, phenols, nitrogen ammoniyny, copper and zincum were used as hydrochemical parameters during the research. The reliable correlation between some water organisms with chemicals and their connections was defined in the water of the Belaya River. The author also constructs for the first time an indicator range of hydrobionts on decrease extent in their response to the chemicals content in the studied water. Similar approach can be used for recommendations development about the use of biological analyses while identifying the chemicals influencing water fauna and flora.
