An analysis of the performance of circle hooks in comparison to J-style and tuna hooks on the hooking rates of target and non-target species, specifically sea turtles, in the artisanal surface longline fisheries of Ecuador, Panama, and Costa Rica was performed. The target fisheries were mahi-mahi and a combination of tunas, billfishes, and sharks (TBS). In the TBS fishery, tuna hooks were compared to 16/0 circle hooks from Ecuador and Panama and 18/0 circle hooks from Costa Rica. For the mahi-mahi fishery, 14/0 and 15/0 circle hooks in Ecuador and 16/0 circle hooks in Costa Rica were compared to traditional J-style hooks. Circle hooks reduced sea turtle hooking rates in most of the comparisons. Hooking rates for target and non-target species were not consistent.
