Marine litter has different impacts on fisheries by damaging gear, reducing catch, and necessitating time to repair or clean nets, making it a significant problem for this industry. This article explores the sources, types, and distribution of marine litter and how production risk and technical efficiency in the trawl fisheries in Vietnam are affected by the presence of litter. The empirical analysis is conducted using data collected from a sample of 208 trawl fishers in Phu Yen, Khanh Hoa, and Ninh Thuan provinces. Our analysis indicates that primary sources of marine litter as reported by fishers are tourism and land-based emissions, with plastic being the dominant type. Litter accounts for 20% of the catch, making it a risk-increasing factor for trawl fisheries and causing technical inefficiency. Our findings emphasize the importance of developing policies for Vietnamese fisheries to jointly address production risks, improve technical efficiency, and decrease marine litter pollution.

海洋垃圾对越南拖网渔业生产风险和技术效率的影响

海洋垃圾通过损坏渔具、减少渔获量以及需要时间修理或清洁渔网等方式对渔业产生不同的影响，使其成为该行业的一个重大问题。本文探讨了海洋垃圾的来源、类型和分布，以及垃圾的存在如何影响越南拖网渔业的生产风险和技术效率。实证分析是使用从富安省、庆和省和宁顺省 208 名拖网渔民的样本中收集的数据进行的。我们的分析表明，渔民报告的海洋垃圾的主要来源是旅游业和陆上排放，塑料是主要类型。垃圾占渔获量的 20%，使其成为拖网渔业的风险增加因素，并导致技术效率低下。
