Movement between different locations might either reduce the potential for individuals to adapt to local conditions or help maintain a population at a given location. This project will develop a set of models to investigate how the interaction between natural selection and movement that vary in both space and time determines the effect of movement on local populations. These models will be based on salmon that receive inputs from aquaculture (fish farming) and hatcheries (supplemental fish raised in captivity), as the many types of such programs provide a data-rich source of information about exchange between populations that experience different (natural and artificial) selection. While factors such as population size, the amount of movement, and variation in selection have been explored separately, how these factors interact to determine the effect of movement on local populations, the central question of this study, remains unknown. In addition to addressing this fundamental scientific question, results of this project will be relevant to pressing questions about the design of hatchery and aquaculture programs. Results will inform the design of hatchery and aquaculture programs that allow for conservation of salmon, an important and threatened natural resource. The project will also provide an educational benefit through graduate student training, which will have a broader societal benefit as federal agencies are struggling to find individuals with postgraduate training in quantitative marine resource management.

不同地点之间的流动可能会降低个人适应当地条件的潜力，或有助于维持某一地点的人口。 该项目将开发一套模型，以研究自然选择和运动之间的相互作用如何在空间和时间上变化，从而确定运动对当地人口的影响。 这些模型将基于从水产养殖（养鱼）和孵化场（人工饲养的补充鱼类）获得输入的鲑鱼，因为许多类型的此类计划提供了有关经历不同（自然和人工）选择的种群之间交换的丰富数据来源。 虽然人口规模，移动量和选择的变化等因素已分别进行了探讨，这些因素如何相互作用，以确定移动对当地人口的影响，本研究的中心问题，仍然是未知的。 除了解决这个基本的科学问题，这个项目的结果将是有关孵化场和水产养殖计划的设计紧迫的问题。 研究结果将为孵化场和水产养殖项目的设计提供信息，从而保护鲑鱼这一重要且受威胁的自然资源。 该项目还将通过研究生培训提供教育效益，这将产生更广泛的社会效益，因为联邦机构正在努力寻找接受过海洋资源定量管理研究生培训的个人。
