Abstract: The article analyzes the fauna of nematodes of the Uchkizil and South Surkhan reservoirs. The study showed that the detected nematode species belong to 9 orders, 39 families of 61 genera and 115 species. As studies have shown, the registered species of the orders Dorylaimida, Chromadorida and Araeolaimida are the most numerous. The nematodes found were distributed among the five ecological groups, among which the species from the groups of para-isobionts and dysaprobionts were more numerous in terms of species and number of individuals.
