I saw a couple of the shows. They never seem to catcha fish. That one guys that switched ships talks to much. I would throw that loud mouth overboard. Micky mouse New Englanders.
There was another show show I saw on Sat that did some serious tun catching. They would catch whole schools and tow them back in nets. Feed them and sell them over in Japan. They had 10 million worth of Tuna. That was quite an operation.
