In this study the effects of toxic pesticides, Diazinon (60% emulsion) on the some tissues of (Rutilus frisii kutum, Kamensky, 1901) male brood stocks were studied. The test were studied under static water quality conditions at 15 °C ± 2 ºC in winter and spring 2009. The effective physical and chemical parameters of water were pH= 7-8.2, dh= 300 mg/L (caco3), DO= 7 ppm and T= 15 °C±2 ºC. LC50 96h pesticide Diazinon on the first 0.4 mg/L was determined and then fish were exposed by the toxin with 3 concentrations, MAC value, LC1, LC5, and a control with three replicates for 45 days. Pathology results showed toxin diazinon no effect on average weight and fish body length, the average weight of heart and brain but caueses decrease of gonad weigth and gonad index and also, cause complications of atrophy, fibrosis and necrosis in testis , vascular congestion, increased distance between the myocardium and fibrous string in heart and neuronal loss, vascular congestion and edema in the brain of kutum male brood stocks.
