抽象的。——研究评估循环的性能和同类规模“J”钩子在大西洋和太平洋旗鱼bob娱官网入口Istiophorus platypterus在较小程度上,在太平洋蓝枪鱼bob娱官网入口Makaira nigricans。终端设备性能评估的钓鱼成功,钩位置和出血与物理钩损和创伤。评估的恶意破坏死诱饵发生了Iztapa(危地马拉,在1999年的春天和夏天,评估和活诱饵漂流/风筝钓鱼发生南佛罗里达在1999年的夏天。

三百六十年太平洋旗鱼陷入Iztapa(危地马拉、bob娱官网入口终端设备性能评估;235旗鱼圈钩,和125年“J”挂钩。圈钩用于旗鱼连接百分比(即。,fish hooked/fish bite) that were 1.83 times higher compared with “J” hooks. Once the fish were hooked, no difference in catch percentage (i.e., fish caught/fish hooked) between hook types was detected. Significantly more sailfish were hooked in the corner of the mouth using circle hooks (85%), as compared with “J” hooks (27%). In contrast, significantly more sailfish were deep hooked in the throat and stomach with “J” hooks (46%), as compared with circle hooks (2%). Only one sailfish (1%) was foul hooked using circle hooks, while 11 (9%) sailfish caught on “J” hooks were foul hooked. Sailfish caught on “J” hooks are 21 times more likely to suffer hook-related bleeding than those caught on circle hooks.
