The present study was conducted to investigate the effects of gamma irradiation on Ichthyophthirius multifiliis trophonts and to determine the effects of exposure on inactivated parasites in rainbow trout. In the first trial, fish were treated with irradiated Ichthyophthirius multifiliis trophonts for 21 days. Results showed that irradiation at doses of 150 Gy and higher was required to inactivate Ichthyophthirius multifiliis trophonts. The LD50 value obtained was 52.2 Gy. In the second trial, the effects of irradiated Ichthyophthirius multifiliis trophonts on physiological and biochemical components of blood and mucus, as well as skin morphology, were studied for 30 days.
