The objective of this study was to determine some of the trace mineral elements in four commercial feeds commonly available in Turkey for marine culture and in fillets of cultured and wild sea bass (Dicentrarchus labrax) and sea bream (Sparus aurata). The feeds and cultured fish were from four different fish farms operating in the same region but with four slightly different feeds. Concentrations of Iron (Fe), Zinc (Zn), Manganese (Mn), Copper (Cu), Lead (Pb), Cobalt (Co), Nickel (Ni), Chromium (Cr), and Cadmium (Cd) were analyzed in the feeds and fillets of cultured as well as wild fish. Significant differences in the mineral concentrations existed within feed groups, cultured fish groups as well as between cultured and wild fish. Fe, Zn, and Mn in the feeds, Fe, Co, and Zn in sea bass and Fe, Zn and Co in sea bream were predominant among the nine analyzed minerals. Fe, Zn, Mn, Cr, and Ni contents in the fillets of wild sea bass were significantly, (P < 0.05) lower than those of the cultured sea bass groups. Co, Cr, Pb, and Ni in the fillets of wild sea bream were also significantly (P < 0.05) lower than those of cultured sea bream groups. These differences in trace elements in the cultured and wild fish were probably related to differences in their dietary mineral concentrations.
