The structure of chironomids\u2019 communities depends on the physical and chemical characteristics of biotopes, as well as water salinity, and is determined by the trophic indicators of the rivers (Zinchenko, Shitikov\u00a0et al., 2014). The quantitative development and biodiversity of chironomids\u2019 larvae significantly correlate with environmental conditions and physicochemical characteristics of\u00a0bottom substrates and water masses.<\/p>\n<p style=\"text-align: justify;\">We determined certain environmental factors, such as total salinity, ionic composition, pH, oxygen concentration, temperature and biotope diversity, that can cause changes in chironomids\u2019 cenosis. Additionally, we provide values of abundance and biomass, and\u00a0frequencies of species occurrence in rivers of different salinity under the influence of abiotic factors. We also present ecological and faunistic characteristics of chironomids as part of bottom communities of highly mineralized rivers of the Lake Elton region.<\/p>\n<p style=\"text-align: justify;\"><em>Keywords<\/em>: highly mineralized rivers, chironomids, taxonomic composition, ecological features, mineralization, abiotic factors, tributaries of the Lake Elton.<\/p>\n<p style=\"text-align: justify;\"><em>Acknowledgements. <\/em>The authors would like to thank Dr. Makarchenko E.V., Dr. Zorina O.V.
