In the middle of the last century, in order to make rational use of the biological productivity of inland water bodies in the USSR, full-scale ichthyo-production works were carried out. In this regard, a complex reconstruction of the ichthyofauna of the Ile-Badhash basin was carried out. The results of these studies led to a change in the species composition of the hydroparasitosis, the appearance of foci of ichthyozoic invasions and the worsening of the epizootological situation in the basin. Now, out of the functional foci of invasive (parasitic) diseases, only the foci of a clinostomosis are aboriginal. The article presents research materials on the parasitic fauna of the eastern bream (Abramis brama orientalis) introduced into the fishery reservoirs of the IleBalkhash basin, as well as the results of a retrospective analysis with varying anthropogenic load using the author’s own writings and data from other scientists. 16 species of fish parasites belong to 6 were revealed as a result of the investigations
