Proximate and Elemental Composition of Chamelea gallina from the Southern Coast of the Marmara Sea (Turkey)


The venerid clam Chamelea gallina is a popular and economic foodstuff around the Mediterranean countries especially in Italy, Spain, and France. The aim of this study is to evaluate the nutritional quality of striped venus of Southern Marmara. Samples were harvested seasonally at five stations and analyzed to determine meat yield, proximate, and elemental composition. According to the results, meat yield ranged from 20.24% to 29.94%. Means of water, protein, lipid, and ash content were 67%, 10.12%, 2.57%, and 1.66%, respectively. The mean concentrations (mg/kg wet weight) of elements in tissues are as follows: B: 2.37–4.24; Cr: 0–0.76; Co: 0–0.43; Cu: 0.71–5.30; Mn: 0.30–5.94; Zn: 13.08–77.76; Ni: 0–1.22; Fe: 2.46–114.22; Al: 1.23–75.49; Pb: 0.18–3.24; Ba: 0.66–15.97; Cd: 0.04–0.69. Among the reported metal levels, only Pb and Zn in two stations exceeded the maximum critical concentrations enforced by Turkish legislation and European Commission. Therefore, we report that striped venus from Southern Marmara Sea, in general, are safe for human consumption; nonetheless, Pb and Zn levels should be closely monitored in the future.
