REDUCING BYCATCH OF THREATENED MEGAFAUNA IN THE EAST CENTRAL ATLANTIC

减少将统一利益攸关方的努力，利用跨学科科学方法减少海洋大型动物的兼捕，并为中东部大西洋的可持续渔业管理提供信息。对该区域所有欧洲工业船队的兼捕数据进行诊断和整合，并将其与捕捞努力和物种的时空分布联系起来，将为共同评估和应对政策挑战提供一种系统的办法。观察员方案的扩大和改进以及电子监测和自动机器学习系统的进步将使海洋大型动物副渔获物的特定物种和高分辨率数据成为可能。结合AIS渔业数据，对选定物种进行精细的GPS跟踪，将有助于了解相互作用的关键驱动因素，并推断政治责任。对该区域精心挑选的物种的新的精细跟踪数据将使人们能够更好地了解它们的丰度和分布以及释放后的死亡率。将结合目击、渔业渔获量和海洋大型动物跟踪数据，逐步改变预测栖息地测绘方法，以了解从地方到盆地的重叠和兼捕风险。将目击事件、渔业渔获量、全球定位系统和全球定位系统跟踪以及捕获-标记-重新捕获研究的时间序列结合在一起，将对大型动物热点和兼捕的风险和影响提供前所未有的看法，从而促进海洋空间规划或中上层水域。对缓解措施的评估和测试将确定显著减少该区域副渔获量的关键方法。创新和高效的数据处理、共享和发布将为兼捕数据社区建立一种综合办法。联合多学科讲习班、科学培训和监测活动将促进与大西洋中东部接壤的科学、渔业和政策制定者之间的能力和合作。

REDUCE will unify stakeholder efforts and utilize an interdisciplinary scientific approach to reduce bycatch of marine megafauna and inform sustainable fishery management in the Eastern Central Atlantic Ocean. The diagnosis and integration of bycatch data across all industrial European fleets in the region, linked with fishing effort and the spatiotemporal distribution of the species, will provide a systematic approach to jointly assess and tackle policy challenges. The expansion and improvement of the observer programmes and the advances in electronic monitoring and automated machine learning systems will enable species-specific and high-resolution data of marine megafauna bycatch. Fine-scale GPS tracking of selected species combined with AIS fishery data in concurrent time will allow understanding key drivers of interactions and infer political responsibilities. New fine-scale tracking data of carefully selected species in the region will allow for a better understanding of their abundance and distribution and post-release mortality. Sightings, fishery catches and tracking data on marine megafauna will be combined to provide a step-changes in predictive habitat mapping approaches to understand overlap and bycatch risk from local to basin-scales. The combination of timeseries of sightings, fishery catches, GPS and GLS tracking and capture-mark-recapture studies, will provide an unprecedented view on megafauna hotspots and the risks and impacts of bycatch, boosting marine spatial planning or pelagic waters. Assessment and testing of mitigation measures will identify key approaches to significantly reduce bycatch in the region. Innovative and efficient data handling, sharing and publishing will establish an integrated approach to the bycatch data community. Capacity and cooperation between science, fishery industry and policymakers bordering Eastern Central Atlantic Ocean will be boosted by joint multi-disciplinary workshops, scientific training and monitoring events.
