| Description | Specimens of N. kessleri were collected from six localities in the Slovakian part of Danube River (former and current main channel), from two adjacent backwaters, and from lower Hron and Váh Rivers during 2002 to 2004. All fish were parasitized. Thirty three species of metazoan parasites were recovered from bighead goby, when most of the parasites were common species in the central Danube River region. In the native area of bighead goby distribution, lower Danube River, 23 parasite species have been reported. Seven widely distributed parasite species (B. polymorphus, D. spathaceum, T. clavata, P. laevis, C. lacustris, E. sieboldi and glochidia of Unionidae) have occurred in both native and non-native area. In total, 88 % of all parasites found composed by glochidia of Unionidae and acanthocephalan. Glochidia of A. anatina and P. laevis were the dominant parasite species. Larval and immature parasites dominated in all fish examined, where bighead goby served as the intermediate or paratenic host. |
