Strategies to balance enhanced fish consumption with sustainable fish production

鱼和贝类是我们饮食中重要和健康的组成部分，但饮食建议是否有助于促进消费，以及建议是否可以基于可持续供应来证明是合理的，仍存在争议。该项目旨在利用研究能力与国家数据库和阿伯丁大学之间的天然协同作用，以更好地了解我们如何简化战略，以提高人类对鱼类和贝类的消费，以实现英国现在和未来可持续生产水产养殖和野生捕捞鱼类的国际建议。该项目将从调查英国潜在的水产养殖承载能力(鱼类和贝类)以及以最大可持续产量捕捞种群时可获得的野生捕捞鱼类的数量开始。这将建立在牵头监督员开展的工作的基础上，根据鱼类生物学知识、捕捞模式和鱼类种群的可变性来模拟种群，将其管理与潜在产量联系起来。在这方面，它超越了对鱼类上岸现状的研究，提供了英国主要鱼类种群在从过度捕捞状态持续复苏后的潜在产量数据。数据将与当前消费者购买量(应用Kantar Worldpanel数据库)和消费模式(应用国家饮食和营养调查(NDNS)数据库)进行比较，以确定在遵守饮食建议时满足需求所需的额外水产品数量。在第二阶段，气候的替代情景和伴随的鱼类种群分布的变化将使我们能够预测引入新的鱼类品种，这些新品种可能在生产和消费方面取代其他品种。对于这两个目标，我们的目标是评估现有的鱼类是否会提供所需的蛋白质、n-3脂肪酸和微量营养素，以实现预期的社会健康改善。一项以消费者为中心的研究将调查新物种在英国是否有潜在的消费市场，以及在多大程度上有潜在的消费市场。关键研究问题：如果英国每个人每周都吃国家推荐的两份鱼，主要是中上层鱼类，会有足够的鱼供人食用吗？考虑到我们是全球市场的一部分？-考虑到目前气候变化的趋势，未来还有哪些鱼类可能更适合水产养殖，以及预计哪些野生鱼类将栖息在我们的水域？-替代鱼类/贝类物种可能的营养成分是什么，这些物种与现有物种相比对人口健康的潜在影响如何？-消费者会不会从英国水域购买和食用任何新的鱼类和贝类物种？如果可以实现适当的进口来源，他们现在会吃这些物种吗？这种由自然资源创造的创新和跨学科的方法社会经济科学家将为改变英国饮食的愿景提供必要的科学基础，以纳入更多以海洋为基础的产品，这将在公共健康方面产生明显的社会影响。在水产养殖和渔业以及英国食品业创收方面的经济影响。

Fish and shellfish are an important and healthy component of our diet, but it is debated whether dietary recommendations help to enhance consumption, and whether recommendations can be justified based on a sustainable supply1. This project aims to exploit the natural synergy between research capabilities and national databases and the University of Aberdeen to better understand how we can streamline strategies to enhance human fish and shellfish consumption towards international recommendations with sustainable production of aquaculture and wild caught fish in the UK, now and in the future.The project would start with an investigation into the potential aquaculture carrying capacity of the UK (both fish and shellfish) and the volume of wild caught fish available when stocks are fished at Maximum Sustainable Yield. This will build on work undertaken by the lead supervisor to simulate populations based on knowledge of fish biology, fishing patterns and variability in fish populations, linking their management to potential yield. In this respect it goes beyond studies of the status quo fish landings to provide data of the potential yield of key UK fish stocks after the ongoing recovery from an overfished state. Data would be compared with current consumer purchasing (applying the Kantar Worldpanel database) and consumption patterns (applying the National Diet and Nutrition Survey (NDNS) database), to establish the additional amount of fish required to meet demand when adhering to dietary recommendations. In the second phase, alternative scenarios of climate and concomitant changes in fish stock distributions will enable us to predict the introduction of new fish species that may replace others in terms of production and consumption. For both objectives, we aim to assess if available fish would provide the required protein, n-3 fatty acids and micronutrients to deliver expected societal health improvements. An overarching consumer-based study will investigate whether and to what extent new species have a potential consumer market in the UK. Key Research Questions: - If everyone in the UK would eat the national recommended two portions of, primarily pelagic, fish a week, would there be enough fish to go around, considering we are part of a global market?- What other fish may be more viable for aquaculture in the future given the current trends in climate change and what wild fish might be anticipated as becoming resident in our waters?- What would be the likely nutritional composition of alternative fish/shellfish species and how would these compare with current species in terms of their potential to impact on the health of the population?- Will consumers buy and eat any new species of fish and shellfish from UK waters or not and would they eat such species now if an appropriate import stream could be realised?This innovative and interdisciplinary approach by natural and socio-economic scientists will provide the required scientific basis for a vision to alter the UK diet to incorporate more marine-based products which will result in clear societal impact in terms of public health, and economic impact in terms of income generation for aquaculture and fisheries, as well as the UK Food Industry.
