Abstract

According to inadequate information about parasitic fauna of Parishan Lake’s fish, six species of fish in Parishan Lake including B. luteus, Barbus grypus , Carassius carassius, Mastacembelus mastacembelus and Cyprinus carpio (Common carp and Mirror carp) were examined for parasitic infestation in faculty of veterinary medicine Islamic Azad university Kazeroon branch. Seven monogenean species or genus including Dactylogyrus extensus, D.anchoratus, D. pavlowsky, D. carassobarbi, D. barboides , Gyrodactylus sp. and Mastacembelus sp. and three protozoan genus including Ichthyophthrius sp., Trichodina sp. and Myxobolus sp. were detected and identified. The results showed that 75.7 % of 74 examined fish were infected however 24.3 % of them had no infection. Highest abundance of infection happened in summer by 88.5 % and the lowest frequency of infection occurred in autumn by 60%. Also the highest rate of infection caused by D. carassobarbi (25 %) and the lowest percentage of it was recorded by D. barboides , D. pavlowsky and D.anchoratus together (1.31 %).One way Anova showed that there was no significant statistics relation between rate of infection and season (P=0.132) and rang of infection between six under study species (P=0.12).
