FAUNA AND ECOLOGY OF HYDROBIOTICS SINANODONTA ORBICULARIS, SINANODANTA RUERORUM AND, COLLETOPTERUM PONDEROSUM VOLGENSE DISTRIBUTED IN AQUATIC ECOSYSTEMS OF URBANIZED AREAS
The main objective of the study was to conduct a comparative analysis of the annual changes in the distribution density of
Sinanodonta orbicularis, Sinanodonta ruerorum and Colletopterum ponderosum volgense in aquatic ecosystems of urbanized
areas. Studies conducted in urbanized areas show that the Darghom Canal's water intake from the Zarafshan River led to the spread
of Sinanodonta orbicularis, Sinanodonta ruerorum and Colletopterum ponderosum volgense distributed in the Zarafshan River,
along with water and fish, to the biotopes of the Darghom Canal located in the urbanized area. The water environment factors,
including water temperature, clarity, flow velocity, and water mineralization, were analyzed to have the greatest impact on the
distribution of these species. A comparative analysis of the distribution and density of species in the canal over the years revealed
that the number and density of species in the following years, 2023 and 2024, were higher than in other years.
