Abstract
Rainbow trout is commercial species that breed all over the world, and Mazandaran Province is one of the important areas of this industry in Iran. The present study was carried out to survey on ectoparasite fauna of cold water fish farms in Mazandaran Province (Iran) during a period of 12 months. For this aim 500 samples were obtained from 50 fish farms and after arriving to laboratory the parasiteexamination started immediately. From the total of 500 specimens, 182 fish (36.4%) were infected with ectoparasites. Through the parasitic examinations five species of parasites were detected, namely: Ichthyophthirius multifillis, Trichodina sp., Chilodonella sp., Gyrodactylus sp. and Dactylogyrus sp. The results showed that, from total percentage (36.4%) of detection, 31.4% of detected parasites were protozoan (16.4% Ichthyophthirius multifillis, 14% Trichodina sp., and 1% Chilodonella sp.) and 5% weremonogenean trematodes (3% Dactylogyrus sp. and 2% Gyrodactylus sp.). The highest prevalence of parasites in our study belonged to the Ichthyophthirius multifiliis causative agent of White Spot Disease.
