title: [Digenea in Melanitta fusca and M. nigra (Mergini, Anseriformes) from the Baltic Sea].
abstract: Ten individuals of Melanitta fusca and M. nigra (Mergini, Anseriformes) each, wintering at the Polish Baltic coast, were examined for the presence of parasites. M. fusca yielded a total of 197 helminths, including 20 digeneans and 177 nematodes. The M. nigra individuals examined were found to support 923 helminths, including 62 digeneans, 860 nematodes, and a single cestode. M. fusca were hosts to the digeneans: Cryptocotyle concava, Notocotylus attenuatus and Psilostomum brevicolle. Digenea found in M. nigra represented: C. concava and Paramonostomum alveatum. The prevalence of P. brevicolle infection (60%) was higher than that of other digeneans; the maximum infection intensity was 40 C. concava individuals in a single M. nigra.
