Impact of Environmental Pollution on Fish in the Arats Reservoir

The study was conducted on fish. As a result, it was determined that, depending on the time and type of pollution, similar pathologies, including edema, exudates, and hemorrhages, are observed in various fish species. The reaction to toxicant exposure manifests as various anomalies and pathologies (nephrocalcitosis, and structural anomalies in the gills, fins, internal skeleton, and skull). A decrease in the fish population of the Araz reservoir living in zones of strong technogenic impact, a reduction in spawning potential, or even complete displacement from their habitats was observed. For the first time, methods for the rational management of fish resources have been developed for the region's reservoirs. The organization of fish weight monitoring, assessment of the impact of economic activities on aquatic ecosystems, compilation of an ecological forecast, and development opportunities and prospects for fisheries have been identified.
