SOME ASPECTS OF STUDYING THE ECOLOGICAL CHARACTERISTICS OF PARASITE FAUNA IN YOUNG RUTILUSARALENSIS UNDER CONDITIONS OF THE AMU DARYA DELTA

Currently, the resolution of problems related to hydrochemical changes in aquatic ecosystems has led to an increase in chemical toxicity in fish, an increase in the prevalence of parasitic infestations, a decrease in the biological productivity of water bodies, and a decline in the ecological purity and sanitary condition of water bodies. Therefore, the main ways to solve the problem of restoring the health of the region's aquatic ecosystems are to monitor the ecological purity and safety of water bodies [3].
