The concentrations of heavy metals were measured by atomic absorption Perkin Elmer 4100. Data analysis was performed with the software SPSS18 and to ANOVA one way. Concentration of Fe, Cu and Co in fish egg of Oncorhynchus mykiss were 0.523±0.061, 0.733±0.152 and 0.23±0.05 mg/Kg (P<0.05). The highest and lowest of accumulation of Fe obtained in liver of female breeding stock (7.35±0.75 mg/kg) and muscle of fingerling (0.39±0.015 mg/Kg). The highest and lowest of accumulation of Cu was in liver of female breeding stock (4.33±0.83 mg/kg) and muscle of fish market (0.53±0.15 mg/Kg). The highest and lowest of accumulation of Co was in gill of female breeding stock (4.26±0.8355 mg/kg) and fish egg (0.23±0.05 mg/Kg).
