DRU Research Community Development Proposal: Workshop on Climate, Uncertainty, and Multilateral Management of Harvested Highly-Migratory Marine Fish Stocks

20世纪后半叶，全球海鱼产量大幅增加。在许多情况下，高度竞争性渔业的扩张导致目标和非目标鱼类种群的规模和弹性下降。目前的捕捞模式被广泛认为是不可持续的，特别是对于捕捞包括金枪鱼和相关物种在内的有价值的高度迁徙物种的国际渔业而言。在这方面，生物海洋学取得了重大进展，需要了解改进对具有商业价值的鱼种的生产力和空间分布的预测的潜在价值。该项目将促进开展协调一致的国际和跨学科社会科学研究工作，重点是在金枪鱼和其他高度洄游海洋鱼类种群的渔业和渔业管理制度的背景下，更好地了解不确定性的影响和改进信息的价值。具体地说，该提案将举办一次关于高度洄游海洋鱼类种群的气候、不确定性和多边管理的研讨会。分析渔业管理问题的现有零碎和受学科约束的社会科学方法已越来越不足以解决这一问题。全球化、对渔业产品日益增长的需求和技术进步导致海洋渔业性质的迅速变化，需要新的分析工具。该项目将促进新的跨学科理论方法和经验分析的必要发展，鼓励开展以下方面的合作研究工作：1)风险和不确定性在以金枪鱼和比目鱼等高度迁徙的海洋顶级捕食者物种为目标的渔业演变中的作用和意义；2)不确定性在渔业管理中的作用，以及替代体制设计的影响；3)关于气候变异性和捕捞活动对这些种群的生产力和空间分布的影响的改进的科学信息的潜在价值。例如，这项工作将为组织为GLOBEC-CLIOTOP项目的国际科学计划提供关于传播研究结果的选择和方法的投入。该项目的最终目标是促进国际多学科研究人员社区的发展，他们的协作工作将为国际渔业管理工作提供有益的指导。讲习班的成果将以印刷形式和在全球网络上广泛传播给学术和管理受众。该项目的教育方面包括学生参加讲习班和一名博士后参加讲习班组织委员会。

Global harvests of marine fish increased substantially during the latter half of the 20th century. The expansion of highly competitive fisheries has led, in many cases, to declines in the size and resilience of both targeted and non-targeted fish populations. Current fishing patterns have been broadly recognized as being unsustainable, particularly for international fisheries exploiting valuable highly-migratory species including tuna and related species. In this context, significant progress in biological oceanography has created a need to understand the potential value of improved forecasts of the productivity and spatial distribution of commercially valuable fish species. This project would facilitate the development of a coordinated international and interdisciplinary social science research effort focused on improved understanding of the effects of uncertainty and the value of improved information in the context of fisheries and fishery management regimes for tuna and other highly migratory marine fish stocks. Specifically, the proposal will hold a Workshop on Climate, Uncertainty, and Multilateral Management of Harvested Highly-Migratory Marine Fish Stocks.Intellectual Merit: A better understanding of the roles of uncertainty and information in competitive international fisheries and in the development and operation of international fisheries governance institutions is urgently needed in order to avoid unintended harm that could arise from creation and dissemination of improved biological forecasts. Existing piece-meal and discipline-bound social science approaches to the analysis of fishery management problems have become increasingly inadequate to address this issue. Rapid changes in the nature of marine fisheries resulting from globalization, growing demand for fisheries products and technical progress require new analytical tools. This project will contribute to the needed development of new cross-disciplinary theoretical approaches and empirical analyses by encouraging collaborative research efforts focused on: 1) the role and significance of risk and uncertainty in the evolution of fisheries targeting highly migratory oceanic top predator species such as tuna and billfish; 2) the role of uncertainty in fisheries governance, and the effects of alternative institutional designs and 3) the potential value of improved scientific information regarding the effects of climatic variability and harvesting activities on the productivity and spatial distribution of these stocks.Broader Impacts: The work will contribute to broader multidisciplinary efforts to develop the scientific basis for sustainable multilateral management of highly migratory marine species in the context of climate-related uncertainties. For example, this effort will provide input to the international science program organized as the GLOBEC - CLIOTOP project regarding options and methods for communicating findings. The ultimate goal of the project is to promote the development of an international, multi-disciplinary community of researchers whose collaborative work will provide useful guidance to international fishery management efforts. Workshop results will be broadly communicated to both academic and management audiences, in print and on the worldwide web. The educational aspects of the project include participation of students in the workshop and participation of one post-doc on the Workshop Organizing Committee.
