QUEST Fish: biomass estimates in four weight categories for exclusive economic zones

QUEST Fish was led by Dr Manuel Barange (PML) with 18 co-investigators from POL, PML, CEFAS, University of Plymouth, University of Portsmouth, CSIC (Spain), UEA, WorldFish Centre, IPSL, ICES (Denmark), Met Office, IRD (Paris) and University of North Carolina, as part of QUEST (Quantifying and Understanding the Earth System)

This dataset collection contains global fish biomass estimates from the Global Coastal-Ocean Modelling System.

QUEST-Fish has delivered a near-global assessment of consequences of climate change for fisheries, demonstrating excellent and innovative bridging of marine biogeochemistry models and socio-economics. QUEST-Fish specifically focused on the added impacts that climate change is likely to cause on global fish production, and on the subsequent additional risks and vulnerabilities to human societies.

The team have demonstrated the broad capability of an integrated regional coastal/shelf seas model system. The physical-ecological POLCOMS-ERSEM model that underpinned the research was developed for Europe’s regional seas. Its application to 20 Large Marine Ecosystems (coastal bioregions) worldwide, covering two-thirds of the world’s fish catch, has been critically evaluated and found adequate for most regions (the physical and biogeochemical differences of the upwelling region off Peru presents challenges, with the climate impact likely to be over-expressed in the fisheries projection output).

由曼纽埃尔·巴拉恩博士（PML）领衔，该团队包括来自POL、PML、CEFAS、普利茅斯大学、朴茨茅斯大学、西班牙CSIC、UEA、世界鱼类研究中心、IPSL、丹麦ICES、气象办公室、IRD（巴黎）以及北卡罗来纳大学等机构的18位共同研究员，作为QUEST（量化与理解地球系统）项目的一部分，共同开展了QUEST-Fish项目。该数据集收集了全球海洋渔业生物量的估算数据。

QUEST-Fish项目对气候变化对渔业的影响进行了近乎全球性的评估，展示了海洋生物地球化学模型与社会科学之间卓越且创新的桥梁作用。项目特别关注气候变化可能对全球渔业生产造成的额外影响，以及随之而来的对人类社会额外的风险和脆弱性。

团队展示了综合区域海岸/大陆架海域模型系统的广泛能力。支撑该研究的基础是物理-生态学POLCOMS-ERSEM模型，该模型专为欧洲的区域海域开发。将其应用于全球20个大海洋生态系统（海岸生物区域），涵盖了全球三分之二的渔业捕捞量，经过批判性的评估，发现其对大多数区域来说是足够的（秘鲁上升流区域的物理和生物地球化学差异提出了挑战，气候影响在渔业预测输出中可能被过度表达）。
