Final Project Report submitted to the U.S. National Marine Fisheries Service. Archie Carr Center for Sea Turtle Research, University of Florida, Gainesville Japanese tuna hook 3.6mm S/S caught significantly more loggerhead sea turtles than non-offset 16/0 and 18/0 circle hooks and caught more turtles in the throat than the circle hooks in the Azores longline swordfish and blue shark fishery. Non-offset 18/0 circle hooks caught fewer loggerhead sea turtles than non-offset 16/0 circle hooks in the Azores longline swordfish and blue shark fishery. There was no significant difference in the number of blue sharks caught on non-offset 16/0 and 18/0 circle hooks in the Azores longline swordfish and blue shark fishery.
