Parasites, causing little apparent damage in feral fish populations, may become causative agents of diseases of great importance in farmed fish, leading to pathological changes, decrease of fitness or reduction of the market value of fish. Despite considerable progress in fish parasitology in the last decades, major gaps still exist in the knowledge of taxonomy, biology, epizootiology and contr...
Trophont stages of the c~l ia te fish parasite Ichthyophtl~jrius n~ult i f i l i is were Incubated alive in vitro in serum from immune carp Cyprinus carpi0 and subsequently examined immunoh~stoloyically for bound ant~body. Parasites became immobilized in immune serum and were enveloped by gelatinous mucus-llke material. Carp antibody could not be detected bound to cilia membranes (the major sur...
آلودگی انگلی دو گونه از ماهیان بومی روخانه بهشتآباد در فصل بهار 1393 مورد بررسی قرار گرفت. در این مطالعه تعداد 52 عدد ماهی، (26 عدد نازک chondrostoma regium و 26 عدد آفانیوس aphanius vladykovi) پس از صید، در آزمایشگاه مورد بررسی قرار گرفتند. پس از انجام زیستسنجی، بررسیهای انگلشناسی با استفاده میکروسکوپ و استرئومیکروسکوپ انجام گرفت. براساس نتایج بدست آمده انگل philometra sp در محوطه شکمی ماه...
Control of the skin parasitic ciliate Ichthyophthirius multifiliis is currently based on laborious chemical and mechanical approaches, thus advocating for alternative control measures. Here, we show that early development trophonts (feeding stage residing in epidermis) Rainbow Trout Oncorhynchus mykiss epidermis was inhibited at 5 d postinfection after administration feed additives, including g...
During a parasitological investigation on the fresh water fishes of North West of Iran (West Azerbaijan Province), 266 specimens of 11 fishes were examined. Fishes were collected from seven stations from Aras, Zangbar and Sarysou Rivers between summer 2001 to summer 2002. Nine protozoan species were detected; eight Cilliophora and one Rhizopoda. Cilliophora are: Chilodonella sp < em>., Apiosoma...
