Abstract:
Fishing for bluefin tuna, which can weigh up to 1,000 pounds and measure ten feet in length, is growing in popularity. Strong annual runs of bluefin make it a popular sport in the winter months off Morehead City and Cape Hatteras. The bluefin is also the subject of one of the largest research projects ever conducted on a single species of fish, the Tag-A-Giant program. The tuna is caught, tagged with an archival tag, and released. The tag transmits data to a satellite about movement, diving activity, depth, light, and external temperatures.
