Abstract
During 2015, 76 specimens of freshwater bream (Abramis brama (Linnaeus, 1758)) were examined by means of standard techniques for parasites. Seven species of parasites (Paradiplozoon homoion (Bychowsky & Nagibina, 1959), Dactylogyrus yinwenyingae (Gusev, 1962), Asymphylodora tincae (Modeer, 1790), Caryophyllaeus fimbriceps (Annenkova-Khlopina, 1919), Acanthocephalus lucii (Miiller, 1776), Acanthocephalus anguillae (Müller, 1780), Contracaecum microcephalum (Stossich, 1890), larvae) were fixed. New parasite and host records were determined. The analysis of the dominant structure of the found parasite taxa were presented to the level of the component communities. All fixed parasite species were component for the parasite communities of examined fish with the exception of A. lucii and A. anguillae. A. lucii is a core parasite species and A. anguillae is an accidental parasite species for the helminth communities of freshwater bream. New data for the lead content in sediments, tissues and organs of bream from the Danube River are presented. From the tissues and organs of the studied fish specimens of A. brama, the lowest concentrations of lead were found in the muscles.
