[Long-term changes in the parasite fauna of the bream Abramis brama L. in eutrophicated lake].
Data on the dynamics of parasite fauna if the bream Abramis brama for 50-year period are presented. The relation between trophic status of the reservoir, preferred type of the bream feeding, and the abundance of its parasites is shown. It was established, that the number of parasites developing in plankton organisms increases during the period of intensive eutrophication. Recent data on the parasite fauna of bream indicate preferred feeding of the host on benthic invertebrates, that is favourable to its growth. Permanent tendency to the increase of the bream invasion by the Diplostomum metacercaria could be a reliable parasitological indicator of the water body eutrophication.
