In this study, parasite infectious of fishes in Ardabil Neor Lake was investigated. Accordingly, 128 specimen of Prussian carp Carassius gibelio, the only species captured from the lake during this survey time, from spring until autumn 2016, once a season were sampled. Due to the climate of the region and because of severe cold weather and freezing of the lake, we did not have any specimen in winter. The fish specimens were in the age range of 1-3 years old and 108 samples female and 20 samples from them were male. Average (±SD) weight and length of fish were respectively 91.56±77.71gand 6.54 ± 15 cm. In the survey of parasitology, monogene trematode of Dactylogyrus anchoratus was isolated and identified in the gills of the fish. The prevalence of this parasite in both spring and summer was 5.88% and 6.7% respectively, and its range was 1 in each season.This research was the first report from contamination of Prussian carp to D. anchoratus. Re-examination of the status of lake fish contamination is necessary before any aquaculture activity.
