N2 - During the two year study a total of 230 specimens of gudgeon (Gobio gobio, L.) were investigated for occurrence of monogenean parasites. Fish were examined monthly. 3685 and 2260 specimens of seven species from three genera were found in 2001 and 2002, respectively. The most abundant monogenean species were Dactylogyrus cryptomeres, Gyrodactylus gobiensis and G. gobii in both studied years. Other parasites observed were specialist species for gudgeon G. markakulensis and generalists G. vimbi, G. gasterostei and with the lowest prevalence Paradiplozoon homoion. Average abundance of D. cryptomeres was about 8 specimens per fish in both years. In the case of gyrodactilids the average abundance was 25 and 11 in 2001 and 2002, respectively. The presence of monogeneans is closely connected to water temperature. The peak of gyrodactylids was in both years two months earlier than the peak of dactylogyrids. The difference was the gyrodactylids reached maximum numbers in March in 2001 and May in 2002 following the curve of water temperature. The maximum intensity of infection was 92 specimens of D. cryptomeres (July 2002), 148 of Gyrodactylus sp. (May 2001) and 2 P. homoion (July 2002) on single fish. All the specimens of D. cryptomeres and P. homoion were unreservedly attached on the gills. Almost 90 % of Gyrodactylids were situated on the fins, than body surface and the gills. In spite of the same parasite species in both years were found, in 2001 the highest number of fish was attacked by five, in 2002 by three monogenean species.
