This study was carried out to detect concentrations of heavy metals (Cd, Pb, Cu, Zn, Fe) in the muscle and liver of female and male specimens of commercially important giant red shrimp (Aristaeomorpha foliacea) obtained from the Mediterranean Sea. Samples of species were collected in summer and winter. The results show that the concentrations of heavy metals in liver for male and female shrimps were higher than those in muscle. Also, the average Cd, Pb, Cu, Zn, and Fe concentrations in both liver and muscle for male shrimp were slightly higher than the average levels of female shrimp. Significant differences were observed only for Cu in liver and for Fe in muscle (p<0.05). The comparison of our results with the International Standards showed that the concentrations of Cd, Pb, Cu, Zn, and Fe in the muscle tissue is less than the authorized range of WHO and FDA standards.

A single adult specimen of spotbase burrfish, Cyclichthys spilostylus (Leis et Randall, 1982), was recorded for the first time on 26 December 2011 from the Mersin Bay, north-eastern Mediterranean, Turkey. This is the first record of the spotbase burrfish C. spilostylus from the marine waters of Turkey and third record on the continental shelf in the Mediterranean basin. This is the 61th record of an Indo-Pacific alien fish species present along the marine waters of Turkey.
