Abstract
The article thoroughly investigates the current state and ichthyofauna of Ponds No. 1 and No. 2 on the Cerkovka River, located in the Gubokovsk District of East Kazakhstan. The study examines the ecological state of water bodies, pollution of water resources, changes in the hydrological regime, as well as the impact of anthropogenic factors. Data on the biological indicators of fish populations in the ponds, including length, weight, and age structure, are presented, and differences and changes between regions are identified. Additionally, the study analyzes the ecological situation, investigating the impact of hydroelectric stations, pollution of water bodies, changes in the oxygen content in the water, and temperature, as well as their effects on fish life. These factors significantly influence the growth, reproduction processes, and population dynamics of the fish. The article also presents recommendations and measures for effective management of fisheries in the ponds. The ichthyofauna of Ponds No. 1 and No. 2 on the Cerkovka River is home to various fish species, including sturgeon, pike, perch, and carp. The analysis of biological indicators allows forecasting population changes and developing measures for their restoration. Additionally, considering ecological changes and anthropogenic impacts, special measures are proposed for the conservation of the natural habitat of fish.
