Marine debris, particularly plastic and abandoned, lost and discarded fishing gear, is ubiquitous in marine environments. This study provides the first quantitative and qualitative assessment of benthic debris using seafloor video collected from a drop camera system in the Bay of Fundy, Eastern Canada. An estimated 137 debris items km of seafloor were counted, comprising of plastic (51%), fishing gear (including plastic categories; 28%) and other (cable, metal, tires; 21%). Debris was widespread, but mainly located nearshore (within 9 km) and on the periphery of areas with high fishing intensity. This baseline benthic marine debris characterization and estimate of abundance provides valuable information for government (municipal, provincial and federal) and for other stakeholders to implement management strategies to reduce plastic and other categories of benthic marine pollution at source. Strategies may include limiting plastic use and reducing illegal dumping through improved education among fishers.
海洋垃圾,尤其是塑料和废弃、丢失和丢弃的渔具,在海洋环境中无处不在。本研究使用在加拿大东部芬迪湾的投放式相机系统收集的海底视频,对海底碎片进行了首次定量和定性评估。估计有 137 公里长的海底有碎片,其中包括塑料(51%)、渔具(包括塑料类别;28%)和其他(电缆、金属、轮胎;21%)。碎片分布广泛,但主要位于近岸(9 公里以内)和渔业强度高的区域周边。这项关于海底海洋碎片特征和丰度的基线研究为政府(市、省和联邦)以及其他利益攸关方提供了有价值的信息,以便实施管理策略,从源头减少塑料和其他类别的海底污染。策略可能包括通过提高渔民的教育水平来限制塑料的使用和减少非法倾倒。
