Derelict fishing gear (DFG) is a highly persistent form of marine pollution known to cause environmental and economic damage. At-sea detection of DFG would support pelagic removal of this gear to prevent and minimize impacts on marine environments and species. In 2008, experts in marine debris, oceanography, remote sensing, and marine policy outlined a strategy to develop the capability to detect and ultimately remove DFG from the open ocean. The strategy includes three interrelated components: understanding the characteristics of the targeted DFG, indirectly detecting DFG by modeling likely locations, and directly detecting pelagic DFG using remote sensing. Together, these components aim to refine the search area, increase the likelihood of detection, and decrease mitigation response time, thereby providing guidance for removal operations. Here, we present this at-sea detection strategy, relate it to relevant extant research and technology, and identify gaps that currently prevent successful at-sea detection and removal of DFG.
废弃渔具（DFG）是一种高度持久的海洋污染形式，已知会对环境和经济造成损害。在海上对 DFG 的检测将支持对该渔具进行中上层清除，以防止和最大限度减少对海洋环境和物种的影响。2008 年，海洋废弃物、海洋学、遥感和海洋政策方面的专家制定了一项战略，旨在开发从公海检测和最终清除 DFG 的能力。该战略包括三个相互关联的组成部分：了解目标 DFG 的特征，通过模拟可能的位置间接检测 DFG，以及使用遥感直接检测中上层 DFG。这些组成部分共同旨在缩小搜索区域，提高检测的可能性，并减少缓解响应时间，从而为清除作业提供指导。在这里，我们提出了这种海上检测策略，将其与相关的现有研究和技术联系起来，并确定了当前阻止成功的海上 DFG 检测和清除的差距。
