At sea requirements—bigeye, albacore, yellowfin, and skipjack

Minimum size requirements for tuna require fishermen to measure in a line tracing the contour of the body from the upper jaw to the fork of the tail. Illustration by Diane Peebles.Management and monitoring measures for Atlantic bluefin tuna go a step further than with the other tuna species we manage. Fresh bluefin is highly prized in global sushi and sashimi markets.

Since it was implemented, the program has reduced the average annual bluefin bycatch by 65 percent compared to the three years before. That’s about 330,000 pounds—or around four fully loaded semitrucks—less bycatch each year.Reporting requirements that track bluefin to market Fishermen using longline gear must use the same vessel monitoring system that tracks where and when they fish to report the number of bluefin retained, discarded dead, or released alive within 12 hours of pulling in their gear.Selected fishermen must complete a logbook report within 48 hours of their fishing activities. These reports include information on which dealer their fish were transferred to, when they were transferred, and the weight of each at the time of transfer.
