Tuna can swim from one side of the ocean to the other? I read the book Giant Bluefin probably 15 years ago. Part of the book was about how the "experts"(government) said there were 2 seperate biomasses and the Atlantic tuna did not cross the ocean, as a way to limit fishing for them. The fisherman said they could and had proof. Funny that Pacific tuna can cross the ocean and come to the US all contaminated. Now the "experts"(government) are using Radiation as a way to scare people into not consuming them. Spin Doctors at work!
