First Record of Dactylogyrus Vastator (Nybelin 1924) (Monogenea: Dactylogyridae) in Common Carp (Cyprinus Carpio Linnaeus, 1758) from Aquaculture Facilities In Macedonia

The representatives of the class Monogenea are great importance in fish pathology. Dactylogyrus vastator (Nybelin 1924) (Monogenea: Dactylogyridae) is a common pathogenic monogenean parasite carp (Cyprinus carpio Linnaeus, 1758) from freshwater lakes and cyprinid ponds, worldwide. In our study, total 133 specimens cage culture system on Mladost Reservoir (N. Macedonia) were subjected to parasitological investigation, by seasons. Only fresh routine identification, dissection, observation methods. Parasite identification was performed morphologically, based character significant organs, using referent keys for determination. found winter, gills 27 carp, with prevalence 2.818%, mean intensity 6.850. During research, presence an aquaculture facility very high stock density. This species would lead mortality it depends primarily intensity, condition, size, as well water temperature oxygen content. records present study considered first N. Macedonia. regarded new host these Macedonian aquaculture.
