Abstract

Metal levels (Cd, Cr, Cu, Fe, Mn, Pb and Zn) in the gill, digestive gland, arm and mantle of female and male short-finned squid (Illex coindetii) in Iskenderun Bay were investigated. All elements differed in accumulation in tissues and sex significantly (p<0.05). Concentrations of Cd in the tissues of male and female shortfinned squid samples ranged between 0.68-9.51 μg/g. Cu concentrations in all tissues were found and ranged between 5.97 and 324.1 μg/g. Fe concentrations in the mantle of female and male samples were found 9.13 and 9.83 μg/g, respectively. Pb concentrations in the mantles of female and male samples were found between 1.49-2.37 μg/g. The highest Zn concentrations in hepatopancreas of male and female samples were found 85.29 and 66.8 μg/g respectively (P<0.05). In the mantle tissue of I. coindetii, metal levels independent of sex were in the following order: Zn > Cu > Fe > Pb > Mn > Cd > Cr. In accordance with limit values, the present study found out that the mantle tissue of cuttlefish, I. coindetii, was overlimited with Cd and Pb.
