项目摘要
Modern fishing nets are made to last. In contrast to other plastic marine pollution, fishing nets are also explicitly designed to entrap marine life. When lost or discarded these durable nylon, polypropylene or polyethylene nets remain intact and afloat for decades. Consequently, they continue to 'ghost fish' valuable fish stocks and damage critical coastal resources like coral reefs essential for sustaining artisanal fisheries and tourism-dependent communities. The now familiar image of lost or discarded fishing nets entangled with decomposing turtles, fish, seabirds and other creatures, attest to the deadly nature of this marine pollution. Less well recognised is the threat these 'ghost nets' pose to the food security and sustainable economic development of developing coastal nations. In 2015 the Global Ghost Gear Initiative (GGGI), a cross-sectorial alliance of stakeholders from the fishing industry, the private sector, NGOs, governments and intergovenmental organisations was launched to drive solutions to the problem of lost and abandoned fishing gear worldwide within the UN Global Partnership on Marine Litter. The GGGI has three strategic approaches; build evidence, define best practices and inform policies, and catalyse mitigation solutions. For the Indian Ocean the major local NGO stakeholder is the Olive Ridley Project (ORP; http://oliveridleyproject.org/), the CEO of which is a previous chair of the GGGI 'Build Evidence' Working Group. Our Innovation Project "Untangling the origin and movement of ghost nets in the Indian Ocean to aid management and mitigation" has been co-developed with both ORP and GGGI.The Maldives are particularly vulnerable to this type of marine debris. Over 700 conglomerates of multiple individual nets and other fishing gear were recovered by Maldivian ORP citizen science volunteers between 2013-2017. These numbers represent only the tip of the iceberg in this vast remote region. Nets are not officially used in Maldivian fisheries, indicating that this local environmental crisis has come from far afield in the Indian Ocean, crossing international borders and turtle migration pathways. Clearly the problem needs addressing at the point of origin, but this is very difficult to pinpoint; the Indian Ocean contains a large number of low-income countries and is an extremely active region for international commercial fishing, as well as illegal and unreported fishing activities. Evidence is required to identify which regional fishing grounds are responsible for the ghost gear. It would also be invaluable for both mitigation and conservation efforts to demonstrate the journey ghost nets take, and areas of accumulation, as they drift across the ocean with the currents. In this project we propose to combine state-of-the-art ocean dispersal modelling and visualisation tools developed at Bristol University using one of the fastest and most advance supercomputing facilities in the UK, with data on recovered ghost nets from citizen science projects run by ORP in Thailand, Pakistan, India, Oman and the Maldives to backtrack their likely source within the Indian Ocean. We will modify our modelling capabilities, originally developed to identify the pathways coral larvae take from one reef to another across thousands of miles, applying this powerful tool to instead simulate the oceanic transport of nets. Visualisation tools developed during a NERC ERIIP funded project to map the probability of jellyfish blooms being transported to coastal power plants will be translated here to communicate the statistical likelihood of ghost gear originating from specific regional-scale fishing grounds stranding in the Maldives and other problem areas. The outcome of our collaboration will be strategic targeting of education and outreach efforts at the responsible sector and region by the ORP based on strong scientific evidence that will also be used by the GGGI to support transboundary decision-making and policy change actions.
现代渔网是为了耐用而制造的。与其他塑料海洋污染相比,渔网也被明确设计为诱捕海洋生物。当丢失或丢弃这些耐用的尼龙,聚丙烯或聚乙烯网保持完整和漂浮数十年。因此,它们继续“幽灵捕鱼”宝贵的鱼类种群,并破坏对维持个体渔业和依赖旅游业的社区至关重要的珊瑚礁等重要沿海资源。现在人们熟悉的画面是,丢失或丢弃的渔网与腐烂的海龟、鱼、海鸟和其他生物纠缠在一起,这证明了这种海洋污染的致命性。人们对这些“鬼网”对发展中沿海国家的粮食安全和可持续经济发展构成的威胁认识不足。2015年,全球幽灵渔具倡议(GGGI)成立,这是一个由渔业、私营部门、非政府组织、政府和政府间组织的利益相关者组成的跨部门联盟,旨在联合国全球海洋垃圾伙伴关系框架内推动解决全球丢失和遗弃渔具问题。GGGI有三种战略方法:建立证据,定义最佳实践和告知政策,并促进缓解解决方案。就印度洋而言,当地非政府组织的主要利益攸关方是Olive Ridley项目(ORP; http://oliveridleyproject.org/),该项目的首席执行官曾担任GGGI“建立证据”工作组的主席。我们的创新项目“解开印度洋鬼网的起源和运动,以帮助管理和缓解”是与ORP和GGGI共同开发的。2013年至2017年期间,马尔代夫ORP公民科学志愿者回收了700多个渔网和其他渔具。这些数字只是这一广大偏远地区的冰山一角。马尔代夫渔业没有正式使用渔网,这表明当地的环境危机来自遥远的印度洋,跨越了国际边界和海龟迁徙路径。显然,这个问题需要从源头上加以解决,但很难确定;印度洋有许多低收入国家,是国际商业捕鱼以及非法和未报告的捕鱼活动极为活跃的区域。需要有证据来确定哪些区域渔场制造了幽灵渔具。这对于减缓和保护努力也是非常宝贵的,因为它们可以展示鬼网随着洋流漂过海洋时的旅程和积累区域。在这个项目中,我们建议结合联合收割机国家的最先进的海洋扩散建模和可视化工具,在布里斯托大学开发的最快和最先进的超级计算设施在英国,与数据恢复鬼网从公民科学项目运行的ORP在泰国,巴基斯坦,印度,阿曼和马尔代夫回溯其可能的来源在印度洋内。我们将修改我们的建模能力,最初是为了识别珊瑚幼虫从一个珊瑚礁到另一个珊瑚礁跨越数千英里的路径而开发的,应用这个强大的工具来模拟渔网的海洋运输。在NERC ERIIP资助的项目期间开发的可视化工具将在这里翻译,以传达来自马尔代夫和其他问题地区特定区域规模渔场搁浅的幽灵渔具的统计可能性。我们合作的成果将是ORP根据强有力的科学证据在负责部门和区域开展教育和外联工作的战略目标,GGGI也将利用这些证据支持跨界决策和政策变革行动。
