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.

拟议研究摘要（最多 500 字）：扇贝部门是英国价值最高的商业渔业之一，支持高产捕捞部门和加工业务。尽管具有经济相关性，英国扇贝渔业缺乏健全的管理制度来规范捕捞量和上岸量并尽量减少对目标和非目标物种的影响。如果缺乏适当的渔业管理措施来促进经济和捕捞效率，渔业就会成为一场资本过剩的疯狂鱼类竞赛。英国退出欧盟是优先考虑和重组未来渔业管理的机会。该项目将评估英国扇贝渔业不同收获策略和管理措施的环境、经济和社会后果。第一章旨在开发英国扇贝评估区的王扇贝（Pecten maximus）种群动态模型。第二章将结合案头研究和渔民调查，确定渔民空间行为的驱动因素（社会、环境和经济）以及他们对扇贝种群管理措施的偏好。第三章和第四章将对扇贝疏浚船队的一系列管理方案进行生物经济评估和环境后果。博士将利用多种不同的数据集和资源，包括（但不限于）英国扇贝种群评估数据、捕捞努力量和上岸量数据集、经济船队数据来了解固定和可变成本、IPCC 的温室气体清单数据库来计算温室气​​体排放，以及底栖沉积栖息地地图。通过该博士学位获得的知识将有助于为未来的渔业管理决策提供信息，以改善扇贝种群的管理，同时还考虑到英国水域商业捕捞船队的不同管理措施的环境和经济影响。
