The purpose of this study was to determine the presence of parasite fauna, prevalence, mean intensity, as well as, seasonal dynamic of parasite species in bighead carp (Hypophthalmichthys nobilis Richardson, 1845) from one of the largest cyprinid aquaculture facilities in Macedonia. A total of 53 specimens of bighead carp from one of the most significant and larger cyprinid aquaculture facilities in Macedonia were subjected on parasitological investigation, by seasons. Monogenea Dactylogyrus aristichthys (Long & Yu, 1958) was found on gills in bighead carp, in spring and autumn. Parasite identification was performed morphologically, based on the character of significant organs, using referent keys for determination. In total, the prevalence with Dactylogyrus aristichthys in bighead carp was 18.87%, while the mean intensity 70.00. Our findings of Dactylogyrus aristichthys in bighead carp are first recorded in Macedonia. At the same time, bighead carp represent a new host for Dactylogyrus aristichthys in Macedonian waters.
