Summary of Proposed Research (MAX 500 words):The scallop sector is one of the highest value commercial fisheries in the UK and supports a productive catch sector and processor businesses. Despite their economic relevance, the UK scallop fisheries lack robust management regimes to regulate effort and landings and minimize impacts on target and non-target species. In the absence of appropriate fisheries management measures that promote economic and harvesting efficiency, fishing becomes a frantic overcapitalized race for fish. The UK's withdrawal from the EU represents an opportunity to prioritise and re-structure future fisheries management. This project will assess the environmental, economic and social consequences of different harvest strategies and management measures for the UK scallop fishery. Chapter 1 will aim to develop a population dynamic model for king scallop (Pecten maximus) in UK scallop assessment areas. Chapter 2 will determine the drivers (social, environmental and economic) of fishers' spatial behaviour and their preference for management measures of scallop stocks using a combination of desk-based research and surveys with fishers. Chapters 3 and 4 will carry out bioeconomic evaluations and environmental consequences of a range of management scenarios for the scallop dredging fleet. The PhD will utilise several different datasets and resources including (but not limited to), UK scallop stock assessment data, fishing effort and landings datasets, and economics fleet data to understand fixed and variable costs, GHG inventory databases from the IPCC to calculate GHG emissions, and benthic sedimentary habitat maps. The knowledge gained through this PhD will help inform future fisheries management decisions to improve the management of scallop stocks, whilst also taking into consideration the environmental and economic implications of different management measures for the commercial fishing fleets in UK waters.

拟议研究的摘要（最多500个单词）：扇贝行业是英国价值最高的商业渔业之一，并支持富有生产力的捕捞型领域和处理器业务。尽管具有经济相关性，但英国扇贝渔业缺乏强大的管理制度来规范努力和着陆并最大程度地减少对目标和非目标物种的影响。在没有适当的渔业管理措施的情况下，促进经济和收获效率的措施，捕鱼成为一场疯狂的鱼类过度资本化竞赛。英国退出欧盟是一个优先和重建未来渔业管理的机会。该项目将评估英国扇贝渔业的不同收获策略和管理措施的环境，经济和社会后果。第1章旨在为英国扇贝评估领域的国王扇贝（Pecten Maximus）开发人口动态模型。第2章将通过基于桌子的研究和与渔民进行调查的结合来确定渔民空间行为的驱动因素（社会，环境和经济）及其对扇贝股票的管理措施的偏爱。第3和第4章将对扇贝挖泥机队进行一系列管理方案的生物经济评估和环境后果。该博士将利用几种不同的数据集和资源，包括（但不限于），英国扇贝股票评估数据，捕鱼工作和着陆数据集以及经济学车队数据来了解固定成本和可变成本，IPCC的GHG库存数据库以计算GHG排放量以及甲属沉积栖息地图。通过该博士学位获得的知识将有助于告知未来的渔业管理决策，以改善扇贝股票的管理，同时还考虑到英国水域对商业捕鱼机队的不同管理措施的环境和经济影响。
