The productivity and resilience of fisheries are subject to a multitude of dynamic and interrelated influences that arise from complex coupling of fish populations with the natural and human systems of which they are a part. With few exceptions, fisheries currently are managed independently, ignoring important natural and human linkages among them. The biological productivity, sustainability, and consequently human benefits of complex fishery systems may be substantially increased if these linkages are better understood and if this understanding is applied to management. The American lobster (Homarus americanus), Atlantic herring (Clupea harengus) and Northeast multispecies groundfish fisheries in the Gulf of Maine are of major ecological, economic, social, and cultural importance to the New England region. They are subject to an array of natural and human linkages that have not yet been systematically studied. This interdisciplinary research project will examine key natural and human linkages among these fisheries and integrate them into a quantitative framework, using numerical modeling to explore how improved understanding of complexity can improve sustainability and increase the flow of human benefits. An important component of the research is the translation of concepts and results into an educational program that will teach a new generation of students about the human and natural complexity of the Gulf of Maine ecosystem and create a sustained interest in marine science. The research is organized by themes. Theme 1 focuses on management of the coupled fishery system. Numerical models will be used to integrate research undertaken in themes 2,3, and 4 and to explore how information regarding interrelated natural and human processes can be used to improve management of these resources. Theme 2 will use econometric estimation and bioeconomic modeling to investigate the human connections between these fisheries that arise through movement of labor and capital between fisheries, regulatory interventions and markets for inputs and outputs, such as herring used as an input to lobster harvest. Theme 3 will synthesize and analyze existing data to characterize variability in transport and survival of early life stages to identify exogenous processes (especially climate-related processes) that drive variability in recruitment. Theme 4 will combine new field studies with analysis of existing data to examine the impact of natural and human-induced trophic interactions among lobster, herring, and groundfish on the population dynamics of these species. Theme 5 will focus on translating research findings into an interactive marine science education program, based at the Gulf of Maine Research Institute, which serves fifth and sixth graders throughout the state of Maine.The project will make important contributions to science by improving basic understanding of the dynamic interrelationships of physical, ecological, and human-economic processes that determine the productivity and variability of the Gulf of Maine lobster, herring, and groundfish fisheries. It also will help develop concepts, research methodologies, and models relevant to fishery systems around the world. There is general agreement on the need to take an ecosystem approach to managing fisheries, but little concrete progress has been made in doing so. This project will develop concepts and methodologies needed to implement an ecosystem approach to fishery management. The project brings together a team of researchers from a broad range of disciplines and will demonstrate the benefits of an integrated interdisciplinary approach to investigating natural-human systems. The research will develop new understanding and approaches for management of important Northeast U.S. fisheries. The new information and insights will be conveyed to fishery managers through seminars, participation in the management process, and publications. The research will be coordinated with an ongoing, interactive marine education activity. A broader goal of that education program is to increase the number of students pursuing education and informed careers in the sciences by generating interest and excitement about science at a critical age. The project also will provide training for graduate students and undergraduate assistants in quantitative, multidisciplinary approaches to the study and management of coupled natural-human systems. This project is supported by an award resulting from the NSF competition focusing on the Dynamics of Coupled Natural and Human Systems.

渔业的生产力和韧性受到多种动态和相互关联的影响，这是由于鱼类种群与它们所属于的自然和人类系统的复杂耦合所产生的。 除少数例外，目前渔业是独立管理的，无视重要的自然和人类联系。 如果更好地理解这些联系，以及将这种理解应用于管理层，则可以大大提高复杂渔业系统的生物生产力，可持续性以及因此的人为利益。 缅因州湾的美国龙虾（美国龙虾），美国鲱鱼（木丘陵）和东北多种地面鱼类渔业对新英格兰地区具有重要的生态，经济，社会和文化重要性。 它们受到尚未系统地研究的一系列自然和人类联系。 该跨学科研究项目将研究这些渔业之间的关键自然和人类联系，并将它们整合到定量框架中，并使用数值建模来探索对复杂性的改善理解如何改善可持续性并提高人类利益的流动。 该研究的一个重要组成部分是将概念和结果转化为一个教育计划，该计划将向新一代学生讲述缅因州生态系统的人类和自然复杂性，并对海洋科学产生持续的兴趣。 该研究是由主题组织的。 主题1专注于耦合渔业系统的管理。数值模型将用于整合主题2,3和4中的研究，并探讨如何使用有关相互关联的自然和人类过程的信息来改善这些资源的管理。 主题2将使用计量经济学的估计和生物经济模型来研究通过渔业和资本在渔业，监管干预措施和市场之间的运动中出现的这些渔业之间的人类联系，以进行投入和产出，例如鲱鱼用作龙虾收获的投入。 主题3将综合和分析现有数据，以表征早期生命阶段的运输和生存的可变性，以识别驱动招募变异性的外源过程（尤其是与气候相关的过程）。 主题4将将新的现场研究与现有数据的分析相结合，以研究龙虾，鲱鱼和基地鱼之间自然和人类诱导的营养相互作用对这些物种种群动态的影响。 主题5将着重于将研究发现转化为缅因州研究所湾的互动海洋科学教育计划，该计划为缅因州的五年级和六年级学生提供服务。该项目将通过对物理，生态经济和人类经济过程的动态相互关系的基本理解来改善基本相互关联，从而对科学做出重要的贡献，从而确定生产力和渔业的生产力和人类的生产力。 它还将有助于开发与世界各地渔业系统相关的概念，研究方法和模型。 关于需要采用生态系统方法来管理渔业的一般共识，但是这样做几乎没有什么具体的进步。 该项目将开发实施生态系统方法进行渔业管理所需的概念和方法。 该项目汇集了来自广泛学科的研究人员团队，并将展示综合跨学科方法来调查自然人类系统的好处。 这项研究将开发新的理解和方法来管理美国东北渔业。 新信息和见解将通过研讨会，参与管理过程和出版物传达给渔业经理。 这项研究将通过持续的互动海洋教育活动进行协调。 该教育计划的一个更广泛的目标是通过在关键时代引起对科学的兴趣和兴奋来增加从事教育和知情的科学职业的学生。 该项目还将为研究生和本科助理提供培训，以进行定量的多学科方法，以研究和管理耦合的天然人类系统。 NSF竞争的奖励是由NSF竞争的奖励支持，该奖项的重点是耦合的自然和人类系统的动态。
