عنوان مقاله [English]
From 2014 in the duration of 24 months ,A total of 172 specimens of 29 fish species of saltwater ornamental fish ones offered for sale in shops in Tehran province which showed symptoms of illness were caught from aquarium and transferred alive to the laboratory. After biometry (total length measurement ) biopsy and wet spread from the skin and the gills of the fish were supplied and examined under photomicroscope (Olympus ch20 bimf200) in the lab. Among the caught species 76.7 % had parasites infection in their skin and gills and 23.3 % were free of such as infection and of the infected fish ,the outer layer of the skin showed the most infection by 97.7 %. Ciliated protozoan parasite (Cryptocaryon irritans) most infection and respectively monogene (Benedinia sp) and flagellate protozoan parasite (Amyloodinium ocellatum) and Turbellarian Sp worms with and ciliated protozoan Parasite (Urinema marinum) and crustacea parasite (Ergasilus sp) and Ciliated protozoan parasite (Euplotes sp) and Ciliated protozoan parasite (Brooklynella sp) and monogene (Dactylogyrus sp) parasite and Ciliated protozoan parasite (Trichodina sp) showed the least infection. This is the first report of saltwater fish parasites mentioned in Iran. The aim of this study is to know external parasites in some saltwater ornamental fish in Tehran Province.
