Twenty different parasite species, comprising one Myxosporea, three Cestoda, four Digenea, seven Nematoda, three Acanthocephala and two Crustacea were found. The parasite component communities comprised 1446 individuals (17 species, six higher taxa) from the Bear Island and 6588 individuals (nine species, three higher taxa) from Pomeranian Bay. The observed parasite host specificity was low, and the intensity in a single fish ranged from one to 279 specimens. The eudominant parasite species were Echinorhynchus gadi , Hemiurus levinseni and Contracaecum osculatum . The dominant parasite communities from the Bear Is − land were nematodes, but acanthocephalans dominated in cod from the Baltic Sea. It appears that one group of parasites, better adapted for the specific conditions of the macrohabitat, has replaced another. The most prevalent parasites were E. gadi , Anisakis simplex , C. osculatum and Hysterothylacium aduncum , and the mean values of crowding were the highest for E. gadi and Pomphorhynchus laevis . The nematode Camallanus lacustris was noted in this host species for the first time. Only six species of parasites were common to cod from both fishing grounds}, type={Artykuły / Articles}, title={Parasite community structure of cod from Bear Island (Barents Sea) and Pomeranian Bay (Baltic Sea)}, URL={http://journals.pan.pl/Content/99500/PDF/10183_Volume32_Issue3_03_article.pdf}, doi={10.2478/v10183−011−0016−6}, keywords={Arctic, Bear Island, Baltic Sea, Gadus morhua, parasite diversity}, }
