太平洋鲑鱼的局部灭绝和steelhead O. mykiss，通常是由于水坝和其他河流障碍，是常见的整个美国西部。在鲑鱼种群历史上占据的地区重建鲑鱼种群有很大的潜力，以协助保护工作，但重新引入的最佳做法还没有很好地建立。在本文中，我们提出了一个框架，旨在促进濒危物种法所列的鲑鱼恢复规划重新引入。在实施一项计划之前，管理者应该首先描述提议的重新引入的贝内、风险和限制。我们将贝内定义为实现恢复目标的特定生物改善。风险是放归的潜在负面结果，可能会恶化保护状况，而不是改善它。限制是生物因素，将决定放归是否成功地建立一个自我维持的种群。我们提供了指导，选择一个殖民化战略（自然殖民，移植，或孵化场释放），一个源人口
Local extirpations of Pacific salmon Oncorhynchus spp. and steelhead O. mykiss , often due to dams and other stream barriers, are common throughout the western United States. Reestablishing salmonid populations in areas they historically occupied has substantial potential to assist conservation efforts, but best practices for reintroduction are not well established. In this paper, we present a framework for planning reintroductions designed to promote the recovery of salmonids listed under the Endangered Species Act. Before implementing a plan, managers should first describe the benefits, risks, and constraints of a proposed reintroduction. We define benefits as specific biological improvements towards recovery objectives. Risks are the potential negative outcomes of reintroductions that could worsen conservation status rather than improve it. Constraints are biological factors that will determine whether the reintroduction successfully establishes a self-sustaining population. We provide guidance for selecting a recolonization strategy (natural colonization, transplanting, or hatchery releases), a source population
