INVESTIGATIONS ON ECTOPARASITIC HELMINTH FAUNA OF SQUALIUS CEPHALUS(L., 1758) LINKED TO ECOLOGIC FACTORS IN SERBAN DAM LAKE, TURKEY

摘要

Squalius cephalus (L.) is a common fish type in the northern hemisphere. In this study, it was aimed to determine ectoparasitic helminth fauna of S. cephalus in Asia Minor situated between Europe and Asia. For this purpose, investigations about ectoparasitic helminth fauna of 114 5. cephalus (L.) caught from Serban Dam Lake (Afyon-karahisar) in inner Asia Minor were done between February 2009 and August 2010. As result of the study, Gyro-dactylus sp. (7.9%, 17.8±16.4) was detected in gills and fins of S. cephalu, whereas Dactylogyrus vistulae (53.5%, 8.5±8.3) was found only in gills. Additionally, prevalence of infestation of these two parasite species, and mean, minimum and maximum infestation intensities were evaluated according to age and sex groups of fish.
