摘要

Abandoned, lost, or otherwise discarded fishing gear (ALDFG) represents a major source of marine plastic pollution, causing significant ecological degradation and socio-economic losses in coastal regions. This study aims to quantify the magnitude of ALDFG, identify its primary causes, and evaluate management opportunities in the coastal waters of Quang Ninh Province, Vietnam. The analysis is based on 500 structured social survey interviews with local fishers, complemented by official government fisheries statistics. Results show that Quang Ninh’s fishing fleet is dominated by small-scale vessels (6–12 m) operating mainly in nearshore waters, with gillnetting and trawling as the most prevalent fishing methods. The estimated ALDFG rates are 9.1% for main/cover nets and 1.8% for rope, with trawling contributing the largest share of discarded nets (23%), while trapping and gillnetting together account for the highest proportion of rope losses (27%). Gear snagging on seabed obstructions was identified as the dominant cause of gear loss (94%), followed by adverse weather conditions (36%) and operational errors (18%). Although 99.6% of fishers reported collecting damaged gear onboard, 93.6% indicated that port infrastructure is inadequate for the proper collection, storage, and recycling of this gear. Fishers expressed strong support for organized gear collection programs, recycling schemes, and financial incentives to reduce ALDFG. The findings underscore the need to integrate ALDFG management into local fisheries governance by enhancing onshore infrastructure, implementing targeted policies, and promoting circular-economy-oriented recycling initiatives. Such measures are essential to mitigate marine plastic pollution and enhance the long-term sustainability of fisheries in Quang Ninh’s coastal waters.
