Bioaccumulation of Heavy Metals in Fish from
Dobrudja Aquaculture Farm

Abstract:

In this study, the influence of pH, temperature and dissolved oxygen on the heavy metals distribution in fish tissue were studied. The bioaccumulation factors of fish tissues were calculated. The heavy metals bioaccumulation was compared in gills, scales, livers, tissue for all the selected fish species: carp (Cyprinus carpio), silver carp (Hypophthalmichthys moilitrix), bighead carp (Aristichthys nobilis) and grass carp (Ctenopharyngodon idella). The samples were taken during 2008, in April and October from aquaculture farm, Sarinasuf. The samples are: water, fish muscle tissue, scales, gill and liver. From the morpho - anatomical fish parts, the heavy metals (Cd, As, Pb, Zn) concentrations in the wet samples were measured. For the water samples, the pH, temperature, dissolved oxygen and the heavy metals (Cd, As, Pb, Zn) concentrations were measured. The lowest bioaccumulation factor was computed for cadmium and the highest, for zinc. The maximum concentration of heavy metals was found in scales. Key words: heavy metals, bioaccumulation, fish, water
