Abstract

The representatives of the class Monogenea are ectoparasites with a direct life cycle and most of them live mainly on the gills or the surface of freshwater or marine fish. Monogenea parasites in aquatic ecosystems are present in large numbers and manifest a clear specificity to their host - fish. They can cause enormous damage not only to the host but also to the aquatic environment. They are also considered to be a sensitive indicator of the health status of an ecosystem.
This study aimed to determine the distribution of parasites of the class Monogenea in cyprinid fish from the Macedonian aquaculture.
656 fish out of 1134 examined were infected with monogenean parasites, with a mean intensity of 6.84, and a prevalence of 57.85%. In this study, the following monogenean parasite species in cyprinid fish were established: Dactylogyrus extensus, Dactylogyrus minutus, Dactylogyrus vastator, Dactylogyrus anchoratus, Dactylogyrus lamellatus, Dactylogyrus aristichthys and Eudiplozoon nipponicum.
Representatives of class Monogenea are commonly occurring during the winter (in 88.89 % of examined fish), followed in spring (56.47%), autumn (45.67%), and less in summer (39.78%). Based on the total number of fish examined from cyprinid aquaculture facilities in Macedonia, the highest prevalence (16.58 %) is determined with Dactylogyrus extensus in winter while the lowest (0.44 %) with Dactylogyrus aristichthys in spring and autumn. The highest mean intensity (90.40) is determined with Dactylogyrus aristichthys in autumn, while the lowest (1.89) with Dactylogyrus minutus and Eudiplozoon nipponicum in spring.
