Metal accumulations in different tissues of cuttlefish ( Sepia officinalis L., 1758) in the Eastern Mediterranean coasts of Turkey

Abstract

In this study, metal concentration levels (Cd, Co, Cr, Ni, and Pb) were investigated in the gill, hepatopancreas, ovary, testis, and mantle of the male and female cuttlefish Sepia officinalis in various stations (Iskenderun, Antalya, Kas, Gazipasa, and Anamur) in Mediterranean coasts of Turkey. Hepatopancreas tissue was a better indicator in terms of heavy metal concentration compared to the other tissues. In general, Cd, Co, Cr, Ni, and Pb accumulation for the male was found more than that of the female, whereas Cd and Ni accumulation was found higher in the female. There was a relationship among the metals in the form of Co > Pb > Ni > Cd > Cr in the mantle tissue. The Pb concentration over the recommended limits was found in cuttlefish of Anamur, Antalya, and Iskenderun stations.
