Parasitofauna of the Ohrid belvica (Acantholingua ohridana Hadzisce, 1961)from Lake Ohrid (Macedonia)

Parasitological examination showed that out of 316 specimens of the Ohrid b elvica (Acantholingua ohridana Hadzisce, 1961; former term Salmothymus ohri danus Steindachner, 1892) from the Macedonian part of lake Ohrid 172 fishes (54.43%) were infected. In our case study the presence of 13 parasite species was established: Dipl ozoon sp., Nicolla testiobliquum, Eubothrium crassum, Eubothrium salvelini, Cythocephalus truncatus, Proteoceephalus neglectus, Proteocephalus torulos us, Raphidascaris acus, Cystidicoloides tenuissima, Metechinorhynchus trutt ae, Metechinorhynchus salmonis, Acanthocephalus anguillae and Pomphorhynchu s bosniacus. Individually, the highest prevalence was found for Cythocephal us truncatus (17.72%). The greatest number of parasite specimens was eviden t in the cases of infection with Cyathocephalus truncatus (32). With the exception of Cyathocephalus truncatus, the other 12 parasite speci es in our study are recorded for the first time in the ichthyoparasitofauna of lake Ohrid and Macedonia.
