ASSESSMENT OF HYDROBIOLOGICAL PRODUCTIVITY OF SMALL RESERVOIRS UNDER THE INFLUENCE OF ECOLOGICAL AND CLIMATIC STRESS FACTORS IN SOUTHERN UKRAINE
Abstract
The research focuses on the main aspects of assessing the hydrobiological and ecological state of small reservoirs in the context of current climate change and its impact on food resources. In the context of anthropogenic load, the impact of military actions on the ecosystems of southern Ukraine, the topic is highly relevant and timely. Given the complex impact of these processes on the food resources of aquatic ecosystems, fish productivity and hydroecological state, the topic also has increased practical significance. This study presents the results of a comprehensive scientific and practical study of the main ecological and economic characteristics of small reservoirs. Hydrobiological and hydrochemical methods were used, a calculated assessment of the natural fish productivity of artificial reservoirs in southern Ukraine was carried out. It is demonstrated that the biomass of phytoplankton, zooplankton, zoobenthos, and macrophytes in the complex determine the natural potential of fish productivity of small reservoirs. The potential of small reservoirs for post-conflict restoration was assessed. It was established that food resources, ecological state and fishery use are a comprehensive basis for the sustainable functioning of small reservoirs. In addition the results of the study are important for developing measures to optimize their ecological and fisheries use.
