摘要

Abandoned, Lost, and Discarded Fishing Gear (ALDFG) in the ocean represents a critical environmental concern for scientists, authorities, and fishermen. Vietnam ranks among the top five countries globally for marine waste emissions, with Kien Giang province operating the largest fishing fleet nationally. This study surveyed 500 fishermen in Kien Giang to assess the current situation, perceptions, and challenges regarding ALDFG reduction. The results revealed that the fishermen had, on average, 16 years of fishing experience and a first-grade education level. Trawl nets were the most commonly used gear, followed by gillnets, long nets, and purse seines, with long net users expressing the greatest ALDFG concern. Each vessel carried an average of 221.94 kg of plastic fishing gear, with snagging on seabed obstructions identified as the primary loss cause. Economic losses were fishermen’s predominant ALDFG concern (agreement level 3.95–4.47 on a 5-point scale), peaking at 4.47 among purse seine users. Time-consuming disposal emerged as the most significant negative impact (3.38/5). Gear maintenance was the most frequently employed loss-prevention strategy, while economic motivations primarily drove ALDFG retrieval to shore (58% for selling, 16% for reuse/recycling). Binary logistic regression identified eight significant predictors of collection behavior (Nagelkerke R²=0.319), time consuming for dealing with litter and economic losses as the strongest motivators. The study recommends enhancing fishermen’s awareness through education-appropriate training programs, implementing economic incentive mechanisms (VAT refund schemes, deposit-refund systems, or cash-for-collection programs), improving port collection infrastructure, and establishing multi-stakeholder coordination frameworks. These interventions should address the low education levels characteristic of this fishing community while leveraging economic motivations and safety concerns to enhance ALDFG recovery efforts in Kien Giang’s marine environment.
