Heavy metals accumulation assessment was carried out in the livers, gills and muscle tissues of the Sea bass Dicentrarchus labrax (Linnaeus 1758) fish species grown in an experimental fish farm in the Dardanelles. The concentrations of the metals in muscle are (mg kg-1, dry wt) Al 37±28; Cd 0.19±0.22; Cr 3.5±1.7; Cu 3.0±0.5; Fe 41±0.5; Hg 0.027±0.007; Pb 20±15; Zn <0.01 and Al, Cd, Cu, Cr, Hg and Fe were found in the order of liver>gill>muscle while the Pb and Zn levels follows the sequence gill>liver>muscle. These Pb and Cd levels are near the permissible limits for human consumption.
