Fascinating video. I hate the part where they shoot the shark but if you can get over that there is someting to this footage. No by catch, no taking the entire school like a seiner, no killing of juveniles if you want too - maybe this is the way forward. The price would be higher for tuna caught like this, certianly the meat would be in better condition, but this may be the answer. And of course the narrator is worth the price of the 10 minutes to watch the video.
