被遗弃,丢失,或丢弃的渔具(ALDFG)是海洋垃圾的主要来源,具有重大的生态和经济后果。我们记录了频率,类型,尺寸,2009年至2021年,ALDFG的影响从北太平洋中部(CNPO)的夏威夷和巴尔米拉环礁恢复。共收回重达十五公吨的二百五十三宗事件,包括120个漂流鱼聚集装置(dFAD)组件,61个企业集团,更少的不同的网,线条,浮标,和独特的齿轮。夏威夷群岛由企业集团和巴尔米拉环礁由dFAD主导。DFAD与东太平洋热带金枪鱼围网渔业有关。迎风O'ahu每月经历多达7个事件或1800公斤ALDFG。横跨夏威夷,ALDFG在55%的调查日出现,包括100%发生的热点。珊瑚礁的破坏,纠缠的野生动物,报告了导航和拆除成本。数据突出显示了ALDFG的大量存在以及CNPO中的相关影响。
Abandoned, lost, or discarded fishing gear (ALDFG) is a major source of marine debris with significant ecological and economic consequences. We documented the frequency, types, sizes, and impacts of ALDFG recovered from Hawai\'i and Palmyra Atoll in the Central North Pacific Ocean (CNPO) from 2009 to 2021. A total of 253 events weighing 15 metric tons were recovered, including 120 drifting fish aggregating device (dFAD) components, 61 conglomerates, fewer distinct nets, lines, buoys, and unique gear. The Hawaiian Islands were dominated by conglomerates and Palmyra Atoll by dFADs. DFADs were connected to the Eastern Pacific tropical tuna purse seine fishery. Windward O\'ahu experienced up to seven events or 1800 kg of ALDFG per month. Across Hawai\', ALDFG was present on 55 % of survey days, including hotspots with 100 % occurrence. Coral reef damage, entangled wildlife, navigational and removal costs are reported. The data highlight the large magnitude of ALDFG and associated impacts in the CNPO.
