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.
废弃、丢失或丢弃的渔具(ALDFG)是海洋碎片的主要来源,对生态和经济都有重大影响。我们记录了 2009 年至 2021 年从中北太平洋(CNPO)的夏威夷和帕尔米拉环礁回收的 ALDFG 的频率、类型、大小和影响。共回收了 253 次事件,重达 15 公吨,其中包括 120 个漂流鱼集鱼装置(dFAD)部件、61 个聚集体、较少的独特网具、绳索、浮标和独特的渔具。夏威夷群岛以聚集体为主,帕尔米拉环礁以 dFAD 为主。dFAD 与东太平洋热带金枪鱼围网渔业有关。瓦胡岛迎风面每月最多有 7 次或 1800 公斤的 ALDFG。在整个夏威夷,有 55%的调查日都发现了 ALDFG,其中热点地区的发现率达到了 100%。珊瑚礁损坏、野生动物缠绕、航行和清除成本都有报道。这些数据突出了中北太平洋大量的 ALDFG 及其相关影响。
