Documenting the extent of fishery gear interactions is critical to wildlife conservation efforts, especially for reducing entanglements and ingestion. This study summarizes fishery gear interactions involving common bottlenose dolphins (Tursiops truncatus truncatus), Florida manatees (Trichechus manatus latirostris) and sea turtles: loggerhead (Caretta caretta), green turtle (Chelonia mydas), leatherback (Dermochelys coriacea), hawksbill (Eretmochelys imbricata), Kemp's ridley (Lepidochelys kempii), and olive ridley (Lepidochelys olivacea) stranding in Florida waters during 1997-2009. Fishery gear interactions for all species combined were 75.3% hook and line, 18.2% trap pot gear, 4.8% fishing nets, and 1.7% in multiple gears. Total reported fishery gear cases increased over time for dolphins (p<0.05), manatees (p<0.01), loggerheads (p<0.05) and green sea turtles (p<0.05). The proportion of net interaction strandings relative to total strandings for loggerhead sea turtles increased (p<0.05). Additionally, life stage and sex patterns were examined, fishery gear interaction hotspots were identified and generalized linear regression modeling was conducted.
记录渔业渔具相互作用的程度对于野生动物保护工作至关重要，特别是对于减少缠绕和误食情况。本研究总结了涉及普通宽吻海豚（Tursiops truncatus truncatus）、佛罗里达海牛（Trichechus manatus latirostris）和海龟的渔业渔具相互作用情况：1997年至2009年期间在佛罗里达海域搁浅的蠵龟（Caretta caretta）、绿海龟（Chelonia mydas）、棱皮龟（Dermochelys coriacea）、玳瑁（Eretmochelys imbricata）、肯氏龟（Lepidochelys kempii）和丽龟（Lepidochelys olivacea）。所有物种的渔业渔具相互作用中，钩线占75.3%，诱捕笼具占18.2%，渔网占4.8%，多种渔具占1.7%。报告的海豚（p<0.05）、海牛（p<0.01）、蠵龟（p<0.05）和绿海龟（p<0.05）的渔业渔具相关案例总数随时间增加。蠵龟因渔网相互作用而搁浅的比例相对于总搁浅数有所增加（p<0.05）。此外，还研究了生命阶段和性别模式，确定了渔业渔具相互作用热点，并进行了广义线性回归建模。
