EVALUATION OF METAL ACCUMULATION, OXIDATIVE STRESS, BIOCHEMICAL AND HEMATOLOGICAL PARAMETERS IN SANDER LUCIOPERCA L., 1758 FROM BAFRA (SAMSUN) FISH LAKES

Abstract

Fish, generally accumulate contaminants from aquatic ecosystems, have been largely used in environmental researches. In this study, heavy metal levels (Cd, Co, Ni, Cu, Fe, Se, Zn, Cr, Mn and As) were determined with ICP-OES in some tissues (muscle, liver, gill, gonad and kidney) of Sander lucioperca L., 1758 living in Bafra Fish Lakes. In addition, antioxidant enzyme activities (CAT, GSH-Px and SOD), MDA levels, blood biochemical and hematological parameters were studied. Generally heavy metal levels in tissues were lower than the limits prescribed in European Communities, the Turkish Food Codex (TFC) and the literature. But, we have found high levels of As, Cd and Zn in some tissues (muscle, gill, kidney and gonad). The changes in the other parameters of our study were also discussed in terms of heavy metal levels. In conclusion, it is possible that heavy metals levels may increase in fishes living in Bafra Fish Lakes in the future via anthropogenic sources. Therefore, we suggest that heavy metal levels should be monitored regularly.
