ABSTRACT
Based on the conducted studies, 35 species of helminths from 32 genera, 22 families, 13 orders, 4 classes and 3 phyla were identified in predatory fish from bodies of water in the middle course of the Syrdarya River. By their life cycle, 24 of the species recorded in predatory fish are biohelminths and 11 geohelminths. The helminths were recorded in predatory fish in the following proportions: Trematoda – 31.4%, Cestoda – 28.5%, Acanthocephala – 8.5% and Nematoda – 31.4%. The level of infection with helminths in predatory fish varies across bodies of water: middle course of the Syrdarya River – prevalence 0.7-30.0%, intensity of infection 1-72 individuals; Aidar Arnasay lake system – prevalence 0.9-27.8%, intensity of infection 1-46 individuals; Tuyabuguz reservoir – prevalence 2.1-26.6%, intensity of infection 1-38 individuals; fishing farms – prevalence 0.3-29.6%, intensity of infection 1-67 individuals; canals – prevalence 3.1-20.3%, intensity of infection 1-42 individuals.
