Abandoned, lost, or otherwise discarded fishing gear is one of the most harmful types of marine litter globally, causing irreversible damage to ocean life and ecosystems. Therefore, global and regional policies are currently being designed and implemented to limit the influx of fishing gear into the marine environment, emphasizing the importance of circular end-of-life management of fishing gear. This study compares the end-of-life circularity potential of the six most used commercial fishing gears in Norway to identify how the heterogeneity of gears impacts their management alternatives. The main findings of the multi-criteria decision analysis (MCDA) applied in this study are that considering the economic and environmental sustainability, as well as technological feasibility of the gears' end-of-life management, purse seines have the most significant circularity potential, followed by trawls and Danish seines, while gillnets, longlines, and traps and pots are most challenging to manage according to circularity principles. Finally, some policy implications of these findings are discussed, considering especially the role of the Extended Producer Responsibility policy in the accommodation for fishing gears' circularity.
废弃、丢失或其他丢弃的渔具是全球最具危害性的海洋垃圾类型之一，对海洋生物和生态系统造成不可逆转的破坏。因此，目前正在制定和实施全球和区域政策，以限制渔具流入海洋环境，强调渔具生命周期结束时的循环管理的重要性。本研究比较了挪威六种最常用商业渔具的生命周期结束时的循环潜力，以确定渔具的异质性如何影响其管理替代品。本研究应用多准则决策分析（MCDA）的主要发现是，考虑到渔具生命周期结束时管理的经济和环境可持续性以及技术可行性，金枪鱼围网具有最大的循环潜力，其次是拖网和丹麦围网，而刺网、延绳钓和陷阱和罐具则根据循环原则最难管理。最后，讨论了这些发现的一些政策影响，特别是考虑到扩展生产者责任政策在适应渔具循环方面的作用。
