Comparison of parasite fauna and fish condition between native and non-native population of round goby (Neogobius melanostomus) in the Danube River

Popis výsledku v původním jazyce

Research was carried out in native area of goby distribution (Danube in Bulgaria) and areas of its introduction (Danube in Slovakia and Austria). In 393 specimens of round goby collected at all Danube localities, a total of 31 species of metazoan parasites were found. Presence of 12 parasite species was recorded in the native area of goby distribution as well as in the areas of introduction. Nevertheless, introduction of parasite species non-native for the Slovak and Austrian sections of the Danube River together with round goby was not observed. Instead, introduced round goby has been infected with 9 new parasite species that are not known in its native population. Parasite species diversity was higher in introduced goby populations compared to nativepopulations. Parasite abundance did not significantly differ between native and introduced populations. Better condition was found in the introduced fish. However, no relationship between condition index values and parasite abundance was
