This study was carried out in order to determine seasonally some heavy concentrations in pike perch (Stizostedion lucioperca) that is fished in Lake Beysehir, which is the third biggest lake of Turkey, consumed and exported. For this purpose, pikeperch seasonally obtained from fishermen in the region in 2011-2012. Heavy metal analyzes of pikeperch were carried out by using inductively coupled plasma optical emission spectrometry (ICP-OES). At the end of the study, minimum and maximum heavy metal concentrations in muscle of pike perch were detected as 0.008-0.047 mg kg(-1) for Cd, 0.033-0.226 mg kg(-1) for Co, 0.024-0.368 mg kg(-1) for Pb, 0.14-0.222 mg kg(-1) for Ni, 0.14-0.301 mg kg(-1) for Cr, 0.326-0.552 mg kg(-1) for Cu, 2.784-4.72 mg kg(-1) for Fe, 5.449-8.859 mg kg(-1) for Al, 15.85-26.497 mg kg(-1) for Zn, 0.215-0.311 mg kg(-1) for Mn. The obtained results were compared in terms of national limit values and international consumed and standart values.
