Lampreys (Petromyzontiformes) are an ancient group of fishes with complex life histories. We created a life cycle model that includes an R Shiny interactive web application interface to simulate abundance by life stage. This will allow scientists and managers to connect available demographic information in a framework that can be applied to questions regarding lamprey biology and conservation. We used Pacific lamprey (Entosphenus tridentatus) as a case study to highlight the utility of this model. We applied a global sensitivity analysis to explore the importance of individual life stage parameters to overall population size, and to better understand the implications of existing gaps in knowledge. We also provided example analyses of selected management scenarios (dam passage, fish translocations, and hatchery additions) influencing Pacific lamprey in fresh water. These applications illustrate how the model can be applied to inform conservation efforts. This tool will provide new capabilities for users to explore their own questions about lamprey biology and conservation. Simulations can hone hypotheses and predictions, which can then be empirically tested in the real world.
七鳃鳗（圆口纲）是一类具有复杂生活史的古老鱼类。我们创建了一个生命周期模型，该模型包含一个R Shiny交互式网络应用程序界面，用于按生活阶段模拟数量。这将使科学家和管理人员能够在一个可应用于七鳃鳗生物学和保护相关问题的框架内，连接可用的种群统计学信息。我们以太平洋七鳃鳗（Entosphenus tridentatus）为例，突出该模型的实用性。我们进行了全局敏感性分析，以探究各个生活阶段参数对总体种群规模的重要性，并更好地理解现有知识空白的影响。我们还提供了选定管理情景（大坝洄游、鱼类转移和孵化场增加）对淡水太平洋七鳃鳗影响的示例分析。这些应用说明了该模型如何用于为保护工作提供信息。这个工具将为用户提供新的能力，以探索他们自己关于七鳃鳗生物学和保护的问题。模拟可以完善假设和预测，然后在现实世界中进行实证检验。
