Abstract. The purpose of our research work in this article is a systematic study of the species composition of helminths in some fish of the reservoirs of the Ferghana Valley and the study of the process of extensive and intensive damage to fish. During the research conducted in 2018-2019, black carp (Schizothorax intermedius) 42 specimens, silver carp (Carassius auratusgibelio) - 47 specimens, carp (Cyprinus carpio) - 68 specimens, grass carp (Ctenopharyngodon idella) - 39 specimens, the number of fish was studied by cutting. 9 species of helminths belonging to 2 species, 3 classes, 6 families, 9 families and 9 genera have been registered in the reservoirs of the Fergana Valley in fish. Of these, 3 belong to the class of cestodes (Cestoda), 2 - to trematodes (Trematoda) and 5 - to nematodes (Nematoda).
