R.acus parasite was isolated from E. lucius and E. erythrophtalmus infecting the species with a mean intensity of 1.1± 11.15 and 1.8±0.83, a prevalence of 15.4% and 20.2% and a mean abundance of 1.69 and 0.38 respectively. C. carpio and R. rutilus were only infected with C. fimbericeps parasite with a mean intensity of 30.30±46.33 and 5±0, a prevalence of 46.5% and 2.78%, and a mean abundance of 15.48 and 0.14 respectively.
