被遗弃,丢失,和废弃的渔具(ALDFG),对海洋环境产生负面影响。由于在损失率方面的知识差距,在加拿大大西洋管理ALDFG具有挑战性,地点,数据可用性/准确性,影响,以及检索的监管障碍。这项研究与当地渔民合作(具有当地知识和实际的ALDFG清除专业知识),清除了新斯科舍省西南部的ALDFG。政府,非营利组织,和学术界。共回收了29,298公斤ALDFG,包括24,630公斤,使用拖曳式抓斗,覆盖约3986公里的海底,距离海岸线4668公斤(包括,68%的龙虾陷阱和12%的牵引电缆重量)。陷阱范围从<1岁到37岁(中位数,10年)。陷阱继续捕获目标和非目标物种,释放了25种,包括652只龙虾(82%为市场大小)和57条鱼(42种处于危险中)。根据估计的2%的陷阱损失,ALDFG在34号龙虾渔区的年度商业损失为155,836加元。
Abandoned, lost, and discarded fishing gear (ALDFG), negatively impacts marine environments. Managing ALDFG in Atlantic Canada is challenging due to knowledge gaps on loss rates, locations, data availability/accuracy, impacts, and regulatory barriers for retrieval. This study removed ALDFG in Southwest Nova Scotia in collaboration with local fishers (with local knowledge and practical ALDFG removal expertise), government, non-profit organizations, and academia. A total of 29,298 kg of ALDFG was retrieved, including 24,630 kg using towed grapples covering ~3986 km of seafloor and 4668 kg from shorelines (comprising, 68 % lobster traps and 12 % dragger cable by weight). Traps ranged from <1 to 37 years old (median, 10 years). Traps continued to catch target and non-target species with 25 species released, including 652 individual lobsters (82 % were market-sized) and 57 fish (42 were species-at-risk). Based on estimated 2 % trap losses, annual commercial losses from ALDFG were $155,836 CAD in Lobster Fishing Area 34.
