Abstract Management Strategy Evaluation (MSE) is an effective tool to gauge the relative performance of fishery management options. For the most part, MSEs have been applied to single-species management procedures. However, to be more inclusive of all the biological and technical interactions occurring within a system, ecosystem-based strategies are emerging. In order to test the feasibility of these strategies, a full ecosystem model should be used as an operating model. Mass balance food web models include many features that managers are interested in and therefore can be useful as an operating model. Until recently, full feedback interactions between a management strategy and a mass balance operating model were impractical. However, with the development of Rpath, users now have the ability to fully customize their mass balance models. We developed new functionality for the Rpath modelling framework that allows it to be used as a flexible operating model. Using an example Georges Bank model, we demonstrate how Rpath can now pause the simulation, evaluate an external model, and use the results to modify the parameters of the operating model. This new flexibility will allow users to test a variety of management strategies or couple to other models making Rpath a valuable tool for conducting MSEs.

使用生态系统模型作为运营模型评估渔业管理战略

摘要 管理战略评估 (MSE) 是衡量渔业管理方案相对绩效的有效工具。在大多数情况下，MSE 已应用于单一物种管理程序。然而，为了更加包容系统内发生的所有生物和技术相互作用，基于生态系统的战略正在出现。为了测试这些策略的可行性，应该使用完整的生态系统模型作为运营模型。质量平衡食物网模型包括许多管理者感兴趣的功能，因此可用作运营模型。直到最近，管理策略和物料平衡操作模型之间的全面反馈交互还是不切实际的。然而，随着 Rpath 的发展，用户现在可以完全定制他们的质量平衡模型。我们为 Rpath 建模框架开发了新功能，使其可以用作灵活的操作模型。我们使用 Georges Bank 模型示例，演示了 Rpath 现在如何暂停模拟、评估外部模型并使用结果修改操作模型的参数。这种新的灵活性将允许用户测试各种管理策略或与其他模型耦合，使 Rpath 成为进行 MSE 的宝贵工具。
