Abstract

Grass carp (Ctenopharyngodon idella Valenciennes, 1844) is one of the most important fish species from family Cyprinidae in the cyprinid aquaculture facilities in N. Macedonia. The aim of this study was to determine the presence of parasite fauna, prevalence, mean intensity, as well as, seasonal dynamic of parasite species in grass carp. A total of 76 fish specimens of grass carp were examined for parasitological investigation from the most significant and larger cyprinid aquaculture facilities in N. Macedonia. Parasite identification was performed morphologically, based on the character of significant organs, using referent keys for determination. In this study, the following parasite species were established: Dactylogyrus lamellatus, Tylodelphis clavata (larvae) and Sinergasilus major. The
highest prevalence (35.52 %) and mean intensity (167.15) was determined with Sinergasilus major in autumn. The records of Dactylogyrus lamellatus, Tylodelphis clavata and Sinergasilus major in grass carp in the present study are considered as the first records for Macedonian aquaculture. The grass carp is regarded as a new host for these parasite species in Macedonian aquaculture. The aquaculture grass
carp can potentially be considered as new host/reservoir for these parasite species in Macedonian waters. The introduction of exotic pathogens by fish imports into the
country should be strictly controlled and evaluated from the outset, in order to protect not only autochthonous fish species but also the aquatic ecosystem itself.
