Strategies balance enhanced fish consumption

项目摘要

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.

鱼类和贝类是我们饮食中重要而健康的组成部分，但饮食建议是否有助于增加消费，以及建议是否可以基于可持续供应1而合理，这是有争议的。该项目旨在利用研究能力和国家数据库与阿伯丁大学之间的自然协同作用，以更好地了解我们如何简化战略，以提高人类鱼类和贝类消费量，实现英国水产养殖和野生捕捞鱼类可持续生产的国际建议，该项目将从调查英国潜在的水产养殖承载能力开始，（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获鱼类数量。这将借鉴首席主管根据鱼类生物学知识、捕捞模式和鱼类种群变异性模拟种群的工作，将其管理与潜在产量联系起来。在这方面，它超越了对现状鱼类上岸量的研究，提供了英国主要鱼类种群在从过度捕捞状态持续恢复后的潜在产量数据。数据将与当前消费者购买（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鱼类数量。在第二阶段，对气候和鱼类种群分布的相应变化的各种设想将使我们能够预测在生产和消费方面可能取代其他鱼种的新鱼种的引进。对于这两个目标，我们的目标是评估现有的鱼类是否能提供所需的蛋白质，n-3脂肪酸和微量营养素，以实现预期的社会健康改善。一项以消费者为基础的总体研究将调查新物种在英国是否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，主要是远洋鱼，考虑到我们是全球市场的一部分，会有足够的鱼吗？考虑到目前的气候变化趋势，未来还有哪些鱼类更适合水产养殖，哪些野生鱼类可能会成为我们沃茨的居民？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在对人口健康的潜在影响方面如何比较？消费者是否会购买和食用来自英国沃茨的任何新品种的鱼类和贝类，如果能够实现适当的进口流，他们现在会食用这些品种吗？自然和社会经济科学家的这种创新和跨学科的方法将为改变英国饮食以纳入更多海洋产品的愿景提供所需的科学基础，这将在公共卫生方面产生明显的社会影响，并在水产养殖和渔业创收方面产生经济影响，以及英国食品工业。
