Research Abstract

We analyzed the stable isotope ratios ofδ^<15> N andδ^<13> C, mercury(Hg) and organohalogen compounds in the red meat(muscle) of the wild bluefin tuna caught at different area of Japan and the bluefin tuna farmed at different areas of Japan. We also analyzed those in yellowfine and albacore tuna caught at different area of Pacific Ocean, and investigated the spatial differences inδ^<15> N andδ^<13> C, Hg and organohalogen compounds. Furthermore, we analyzedδ^<15> N andδ^<13> C and Hg in male and female of spiny dogfish and star-spotted dogfish, and investigated the effects of growth rate and aging on the Hg accumulation and distribution.
