Intensive aquaculture supply the ever growing population with highlynutritious protein, but also comes with problems which include more frequent outbreaks of parasitic diseases infish farms and transmission of diseases between different farms or countries.Cyprinid fish farms usually have an area of 10-100 ha, with water depth of 1-2 m. The optimal watertemperature is 25°C, the amount of dissolved oxygen is 7-9 mg/l and the pH range from 7 - 8. The mostcommon fish that are grown here are those from the family Cyprinidae, such as common carp, grass carp,bighead carp and silver carp.Cyprinid fish farm Bukri is located in the southeastern part of Pelagonia (Bitola, Macedonia). It was built in1960/61, with the enclosure of part of the Crna River old bed with two embankments and occupies an area of 55ha.The aim of this study was to determine the parasite fauna in common carp (Cyprinus carpio, L. 1758) fromcyprinid fish farm located in Pelagonia region (Bitola, Macedonia) by seasons, as well as, percent of infestationwith parasites. Fish were caught by net and fish species were determined according key of Kottelat & Freyhof(2007). Fish samples were examined by standard parasitological methods. Fish gills, fins, body cavity, intestineand eyes were studied. Collected, cleaned parasites were separated and put in certain fixatives, prepared withdetermined techniques of staining and clearing (Vasiljkov 1983, Gussev 1983). The remaining parasites werefixed with 19:1 glacial acetic acid-formalin. Keys of Bauer (1985, 1987) were used for parasite determination.During the investigations, stereomicroscopes „Zeiss”- Stemi DV4 and „MBS 10”, as well as light microscope„Reichart” with magnifications of 40 - 100 X were used.Total, 157 specimens of common carp (Cyprinus carpio, L. 1758) from cyprinid fish farm Bukri located inPelagonia region (Bitola, Macedonia) were examined and 112 fishes (71.34%) were infected with parasites. Incommon carp from this cyprinid fish farm the presence of 5 parasite species was established: Trichodina sp.,Dactylogyrus extensus, Dactylogyrus minutus, Eudoplozoon nipponicum and Raphidascaris acus.Read More
