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.

REDUCE将统一利益攸关方的努力，利用跨学科的科学方法减少海洋巨型动物的副渔获物，并为大西洋中东部的可持续渔业管理提供信息。对该地区所有欧洲工业船队的兼捕数据进行诊断和整合，并与捕捞努力量和物种的时空分布联系起来，将提供一种系统的方法来联合评估和应对政策挑战。观察员方案的扩大和改进以及电子监测和自动化机器学习系统的进步，将有助于获得海洋巨型动物兼捕物的具体物种和高分辨率数据。对选定物种的精细尺度GPS跟踪与AIS渔业数据相结合，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进行新的精细跟踪数据将有助于更好地了解其丰度和分布以及释放后的死亡率。有关海洋巨型动物的观测、渔获和跟踪数据将结合起来，提供预测性生境制图方法的逐步变化，以了解从地方到流域规模的重叠和兼捕风险。将观测、渔获、全球定位系统和全球定位系统跟踪以及捕获-标记-再捕获研究的时间序列结合起来，将提供关于巨型动物热点以及兼捕的风险和影响的前所未有的视角，促进海洋空间规划或中上层沃茨。对缓解措施的评估和测试将确定大幅度减少该区域副渔获物的主要方法。创新和有效的数据处理、分享和公布将为混获数据界确立一个综合办法。将通过联合多学科讲习班、科学培训和监测活动，加强科学、渔业和大西洋中东部沿岸政策制定者之间的能力和合作。
