Abstract

Lake Ohrid is situated in the Ohrid valley and occupies the farthest southwest part of the Republic of Macedonia. It belongs to the category of oligotrophic lakes.
Lake Ohrid fish fauna is represented by 17 autochthonous species, among which 60% are endemic in terms of species or subspecies. Ten species are commercially important, priority being given to the two endemic and relic trout species - Ohrid trout (Salmo letnica Karaman, 1924) and Belvica (Salmo
ohridanus Steindachner, 1892).
In order to explore the parasite fauna of endemic fishes from Lake Ohrid, sampling of fish material was carried out by seasons in one year.
During that period, 203 specimens of fish were caught, which belong to 2 species: Ohrid Trout - Salmo letnica and Ohrid Belvica - Salmo ohridanus.
Parasitological examinations of the fish from the Macedonian part of Lake Ohrid were made on 78 specimens of Ohrid’s trout (Salmo letnica Karaman, 1924), of which 59 fishes (75.64%) were infected. We determined the presence of 4 parasite species in Ohrid’s trout (Salmo letnica): Eubothrium crassum, Cyathocephalus truncatus, Proteocephalus neglectus and Pomphorhynchus laevis.
Parasitological examinations of the fish from the Macedonian part of Lake Ohrid were made on 125 specimens of the Ohrid’s belvica (Salmo ohridanusSteindachner, 1892), of which 68 fishes (54.40%) were infected. We determined the presence of 7 parasite species in Ohrid’s belvica (Salmo ohridanus): Discocotyle ohridana n.sp., Nicolla testiobliqua, Eubothrium salvelini, Metechinorhynchus truttae, Metechinorhynchus salmonis, Acanthocephalus anguillae and Pomphorhynchus bosniacus.
