    Comparative study on biochemical composition of some edible marine molluscs at Canakkale coasts, Turkey
    (Natl Inst Science Communication-Niscair, 2014) Celik, MeryemYesim; Culha, Saniye Turk; Culha, Mehmet; Yildiz, Harun; Acarli, Sefa; Celik, Ihson; Celik, Painar
    Present study was carried out, at Dardanelles and the Marmara Sea coasts during March 2011 to February 2012. Ostrea edulis, Mytilus gallopro, Ruditapes decussa, Ruditapes pheleppirnarum and Rapona venosa were collected seasonally along with temperature and salinity. Biochemical composition of molluscs (protein, lipid, carbohydrate, moisture and ash) was examined from the samples. Seasonal values of protein, lipid, carbohydrate, ash and moisture were mean 64.71 +/- 1.31%, 1.86 +/- 0.10%, 24.09 +/- 1.33%, 9.35 +/- 0.26% and 67.51 +/- 1.47% in R.venosa; 55.88 +/- 2.04%, 5.60 +/- 0.19%, 23.43 +/- 1.59%, 15.10 +/- 0.67% and 83.28 +/- 0.86% inR. philipinarium; 56.27 +/- 1.98%, 5.82 +/- 0.34%, 23.39 +/- 1.62%, 14.53 +/- 0.66% and 83.58 +/- 0.59% in R. decussatus; 54.03 +/- 2.82%, 10.52 +/- 1.22%, 22.84 +/- 4.33%, 12.61 +/- 2.54% and 82.45 +/- 1.70% in M. galloprovincialis; 48.11 +/- 3.04%, 8.81 +/- 0.65%, 29.16 +/- 4.62%, 13.92 +/- 1.89% and 82.25 +/- 2.66% in O. edulis, respectively. Consequently, the sampled mollusc species has high protein (40.19 - 67.38 %) and low lipid (1.65 - 12.86 %). Overall, R. venosa appears to be best as diet with relatively high protein and low lipid among other examined molluscs.

    Metal concentrations, selenium-mercury balance, and potential health risk assessment for consumer of whiting (Merlangius merlangus euxinus L., 1758) from different regions of the southern Black Sea
    (Springer Heidelberg, 2023) Yildiz, Harun; Bayrakli, Baris; Altuntas, Mutlu; Celik, Ihsan
    The significant increase in the human population and the associated industrial wastes have a widespread impact on coastal areas. It is important to monitor trace elements that affect food safety and pose a potential consumer health threat. All over the Black Sea coast, people enjoy consuming whiting as both meat and roe. In February 2021, whitings were caught by bottom trawling from four different locations on the coasts of Kastamonu, Sinop (Sarikum, Adabasi), and Samsun in the southern Black Sea region. The meat and roe extracts obtained from whiting samples were analyzed through an optical emission spectrophotometer (ICP-MS). Trace element concentrations of whiting meat and roe in this study were Zn > F e > Sr > As > Al > Se > B > Mn > Cu > Hg > Li > Ni > Ba > Pb > Cr > Cd and Zn > Fe > Al > As > Cu > Sr > Mn > Se > B > Ba > Li > Ni > Hg > Cr > Pb > Cd, respectively. These amounts were lower than the acceptable values accepted by the EU Commission. In case of whiting and roe consumption of a maximum of three portions (860.33 g) for Adabasi, six portions for Kastamonu (1432.37 g), three portions for Samsun (828.55 g), and five portions (1253.04 g) for Sarikum per month do not pose a health risk.
