  • Bluefin tuna are large, fast swimming fish that sushi-lovers prize. In the north Atlantic, the species' numbers have decreased dramatically. The spawning population is believed to be 21 to 29 percent of what it was in 1970. Fishing of bluefin tuna is now strictly regulated in the United States.

    1. Why do tuna fishers want to obey fishing regulations?

      Tuna fishers want to maintain the bluefin populations, so that they may maintain their profession.

    2. What happens if tuna fishers catch a fish that is less than the minimum of 185 centimeters (73 inches) long?

      The fish is released back into the ocean.

    3. In the United States, how do fishers catch bluefin tuna?

      Fishers catch bluefin tuna with a rod and reel or hand-thrown harpoon.

    4. Why is longline fishing less sustainable than rod and reel fishing?

      Longline fishing catches lots of fish of different species, including some that are not large enough to be caught. Rod and reel fishing catches one fish at a time, which is quickly brought to the boat and measured to be sure it meets minimum size requirements.
