In this article, the species composition, density and physicochemical properties of zooplankton organisms for different types of water bodies of the Dengizkul water basin were studied. During the study, water samples were taken from 3 contours of the Dengizkul water basin, a cirrhotic channel, and collectors. Zooplankton were identified microscopically and separated into species using spectrometers. The systematic description of zooplankton species, the relative differences in the zooplankton of the water body due to the fact that samples were collected at different times and from different water depth layers, were studied in cross-sectional areas. A number of factors such as water temperature, pH level, oxygen content and degree of mineralization were identified as the main factors affecting the composition and density of zooplankton. The results obtained are of important scientific and practical importance in assessing and improving the ecological status of Lake Dengizkul.
