An important step in solving the problem of the quality of fresh water is the assessment of the ecological status of watercourses. Currently, the ecological status of watercourses in the Russian state monitoring system is assessed by a complex of complex indicators, mainly based on traditionally used chemical microbiological methods. The system of biological monitoring in Russia is poorly developed, and the use of aquatic invertebrates is limited to only two GOST indicators, whereas in world practice biological monitoring systems are developing at an accelerated rate. Expanding the methods of biological monitoring and the introduction of modern biomass technologies into the practice of the Russian state monitoring would make it possible to enrich the system with new methods and approaches and evaluate the state of watercourses according to a larger number of criteria. This article presents the use of freshwater insects to assess the quality of freshwaters, the main methods for assessing the state of freshwater bodies using invertebrates, and also discusses new indices based on the fractional presence of netting caddis bugs.
