Summary
The use of circle hooks (16/0) instead of J hooks (size 2) on pelagic longline gear, reduced the incidental capture of immature loggerhead sea turtles (Caretta caretta) and did not affect the catch rates or fish size of the target species (primarily swordfish (Xiphias gladius) and tuna (Thunnus spp.)). There was also a significant difference in hook location between the two hooks, with more J hooks being swallowed.
