In this study, a total of 72 Pseudophoxinus antalyae and 58 Cyprinus carpio have been investigated during February through August 2004. In P. antalyae the prevalence and mean intensity level of Dactylogyrus sphyrna was 2.7% and 1.5 +/- 0.5 respectively, D. ergensi was 38.8% and 16.1 +/- 1.09 and Paradiplozoon homoion was 73.6% and 8.15 +/- 0.47. Two monogeneans were found on the gills of C. carpio namely D. extensus at a prevalence of 23.6% and a mean intensity of 13.5 +/- 2.49 and P. homoion with a prevalence of 1.3% and mean intensity of 1.0. In the intestine of C. carpio Caryophllaeus laticeps occurred at a prevalence of 48.2% and mean intensity of 4.03 +/- 0.43. Paradiplozoon homoion was the dominant species in P. antalyae, whilst in C. carpio the dominant species was C. laticeps. This report provides the first record of Dactylogyrus ergensi in Turkey.
