Özet: The present study investigated metal accumulation in tissues of Capoeta bergamae and its relation to individual mean (multi-metal) bioaccumulation index (IMBI). Metals in fish were analyzed by ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectrometry). Metal accumulation of C. bergamae was investigated three seasons on 2011. The average maximum concentrations of Cd (0.592±0.32), Co (0.786±0.53), Cu (71.682±66.01) and Fe (159.569±102.48) were determined high in liver on spring, while Zn (86.875±93.76) and Se (2.297±2.00) concentration was found high in liver on winter. On the other hand, Mn (16.354±8.87), Cr (5.789±8.36) and Al (91.796±47.46) concentrations were found highly in muscle on winter. Generally, higher concentrations of the measured metals were found in the spring compared with those during autumn and winter. IMBI values varied from 0.07 to 0.41, 0.03 to 0.31 and 0.04 to 0.34 in liver, muscle and gill respectively. Generally, mean IMBI values calculated in liver (0.18±0.09) were higher than other tissues (0.14±0.08 for muscle and 0.16±0.09 for gill). Average Cd and Pb concentrations in the fish muscle were higher the maximum allowed concentrations for human consumption.
