Study on Parasites of fishes in Sooleghan lagoon, Chaharmahal & Bakhtyari Province

Sixty-six fish specimens in different species including Cyprinus carpio، Carassius auratus gibelio and Capoeta aculeata from Cyprinidae family were studied for parasiticinfestation in spring and summer 2008. After fishes were identified to species level according to freshwater fish identification keys، biometric operations were examinedfor parasitic infestation. Parasite species found in examined fishes were: Dactylogyrus extensus، D. anchoratus، Gyrodactylus sp، Ichthyophthirius multifiliis and Diplostomum spathaceum in C. carpio and C. auratus fish، D. lenkorani in C. aculeata species andLernea cyprinacea in three species. 68. 1 percent of examined fishes were infected to parasites and 39. 1 percent didn''t have any parasitic infestation. Among parasitesabove Lernea cyprinacea could infect considerable number of fishes as the infestation rate in common carp and Capoeta were 41. 5 and 88. 8 percent respectively.
