As a result of the study of 10 specimens Perca fluviatilis Linnaeus, 1758 and 10 specimens Vimba melanops (Heckel, 1837) from the Maritsa River, Aegean water basin, Bulgaria, infection with 5 helminth species are presented (Allocreadium isoporum (Loos, 1894); Proteocephalus percae (Müller, 1780); Caryophyllaeus laticeps (Pallas, 1781); Contracaecum sp., larvae and Acanthocephalus lucii (Müller, 1776)). All identified parasite species are autogenous to the parasite communities of the perch and Macedonian vimba, except Contracaecum sp., which is an allogeneic species. Infection indices are discussed and pathways of helminth flux circulation are traced. The dominant structure of the helminth communities was analyzed. New data on the helminths and their communities in the two species of freshwater fish, as well as on the ecological status of the studied biotopes of the freshwater ecosystem are presented.
