The fish species included Esox lucius, Cyprinus carpio, Blicca bjoerkna, Tinca tinca, Carassius auratus, Rutilus frisii kutum, Rutilus rutilus and Scardinius erythrophtalmus.

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. The parasite A. tincae was observed only in T. tinca infesting the.....
