POPULATION INDICATORS OF GIRDOBIONTS. (MIRZACHUL AREA)

Environmental studies of populations of hydrobionts such as Unionidae, Corbiculidae, Beelgrandiellidae, Lymnaeidae, Physidae, Planorbidae, Astacidae, and Haemopidae are mentioned. These organisms play an important role in the processes of self-purification and water quality management of water bodies, helping to ensure the stability of the aquatic ecosystem. The study of their diversity and distribution is directly related to the current state of the environment, especially in the context of climate change and anthropogenic impact. Research is carried out in the Mirzachul area, specifically in the Sirdarya and Sangzor river systems and in the Southern Mirzachul and Dustlik canals. The results show a correlation between water resource status and hydrobiont populations. This is decisive for the management of Water Resources and the conservation of biodiversity.
