Abstract A total of 958 specimens of farmed common carp Cyprinus carpio from eight of the most significant and largest cyprinid aquaculture facilities in Macedonia (pond and cage culture systems) were examined for parasitological investigation for three years. The following parasite species of the genus Dactylogyrus were identified: Dactylogyrus extensus, Dactylogyrus minutus and Dactylogyrus anchoratus. The highest prevalence was determined for D. extensus (38.8%), followed by D. minutus (7.9%) and D. anchoratus (2.8%). The highest mean intensity was determined for D. extensus (6.2), followed by D. minutus (4.7) and D. anchoratus (3.8). By seasons, the highest prevalence (16.5%) was recorded for D. extensus in winter, while the lowest (0.6%) for D. minutus in autumn. The highest mean intensity (8.0) was also determined for D. extensus in winter, and the lowest (1.9) for D. minutus in spring.

The aim of this study was to determine the distribution of parasites of the class Cestoda in farmed common carp from the cyprinid aquaculture facilities in Macedonia. The representatives of the class Cestoda occur most often during the winter (in 3.47% of examined fish), followed by spring (1.80%) and autumn (1.73%). They haven`t been identified during the summer. 20 fish out of 958 totally examined were infected with cestodes, with a mean intensity of 6.40, and a prevalence of 1.76%. In this study, the following parasite species were established: Caryophyllaeus fimbriceps, Bothriocephalus opsariichthydis and Ligula intestinalis (plerocercoid). Based on the total number of fish examined from cyprinid aquaculture facilities in Macedonia, the highest prevalence from the class Cestoda is determined by Bothriocephalus opsariichthydis (1.04%), followed by Caryophyllaeus fimbriceps and Ligula intestinalis with 0.55% each. The highest mean intensity with parasites of the class Cestoda is determined by Caryophyllaeus fimbriceps (9.40), followed by Bothriocephalus opsariichthydis (6.30) and Ligula intestinalis (3.60). The records of Caryophyllaeus fimbriceps in farmed common carp in the present study are considered as the first records for Macedonian aquaculture.

Eudiplozoon Nipponicum

A total of 958 specimens of common carp from the most significant and larger cyprinid aquaculture facilities in Macedonia, including fish farms and reservoirs, were examined for parasitological investigations. Eudiplozoon nipponicum was found on gills in 121 specimens of common carp in spring, summer and autumn, with a prevalence of 10.67 %, and a mean intensity of 2.55. Our findings of E. nipponicum in common carp from aquaculture are first recorded in Macedonia.

The aim of this study was to determine the protozoan parasites in common carp (Cyprinus carpio, L. 1758) from the largest cyprinid aquaculture facility in Macedonia, located in Pelagonia region (Bitola). This study was carried out by seasons, in a period of three years. A total of 212 specimens of common carp were examined and 134 fish (63.20%) were infected with protozoan parasites. Representatives of Protozoa were most commonly occurred during the spring (in 58.27 % of the fish examined), than in winter (55.21 %), summer (39.07 %) and the lowest in autumn (35.64 %).In common carp from this cyprinid fish farm the presence of 4 protozoa species was established: Myxobolus müelleri, Myxobolus encephalicus, Thelohanellus nikolskii and Trichodina sp. The mean intensity with protozoan parasites in common carp was 3.60, while the prevalence 10.20 %.
