Marine debris is an international environmental issue, and the growing amount of abandoned, lost, or otherwise discarded fishing gear (ALDFG) is a particular concern. Despite Taiwan's substantial fishing industry, there is a lack of comprehensive understanding of fishing gear. This work conducted a static material flow analysis to estimate the flows and the stocks of fishing gear in Taiwan in 2020, based on government statistics and interviews with fishing gears producing companies, fishermen, and recycling companies. Our findings reveal that the inflow, outflow, and stock of the fishing gears are 8,846 t/a, 4,271 t/a, and 4,575 t/a, respectively. Only 36 % of end-of-life fishing gear is recycled, while the rest is incinerated or landfilled. Additionally, the stock comprises 27 % in use, 23 % in ports, and 50 % entering the ocean. These results underscore the need to increase recycling capacity, prevent loss in oceans, and promote repairs to extend the lifespan of fishing gear.
海洋垃圾是一个国际环境问题，而废弃、丢失或其他丢弃的渔具（ALDFG）数量的不断增加尤其令人关注。尽管台湾拥有庞大的渔业，但对渔具的了解还不够全面。本研究基于政府统计数据和对渔具生产企业、渔民和回收公司的访谈，进行了静态物质流分析，以估算 2020 年台湾渔具的流动和存量。我们的研究结果表明，渔具的流入量、流出量和存量分别为 8846 吨/年、4271 吨/年和 4575 吨/年。只有 36%的报废渔具被回收，其余的则被焚烧或填埋。此外，存量中 27%在使用中，23%在港口，50%进入海洋。这些结果强调需要增加回收能力，防止渔具在海洋中丢失，并促进维修以延长渔具的使用寿命。
