ANALYSIS OF THE IMPACT OF ECOLOGIC FACTORS ON THE FISH FAUNA OF THE RIVER TISZA

The conditions of existence of river organisms and the mapping of their habitats have been studied using the example of the Tisza River in Transcarpathia, which plays a key role in preserving biodiversity and the stability of natural environments. River ecosystems are important components of nature conservation practice, and their study contributes to understanding the impact of natural factors on the biotic component of river systems. The influence of hydrodynamic and hydrochemical indicators on river fauna, as well as the characteristics of fish migration under the influence of temperature changes and floods, have been investigated. The results of the research indicate a great diversity of fish species in the Tisza basin, including those listed in the Red Books. The methodology of the study, based on the analysis of normal living conditions and the use of geoinformation technologies, allows obtaining important data for further improvement of nature conservation measures in the region.
