本文提出了一个商业渔业面临外来物种生物入侵的生物经济模型，外来物种是本地物种的空间竞争者。该模型是说明在一个案例研究中常见的扇贝渔业的圣布里厄湾（法国），生物入侵的拖鞋帽贝（Crepidula fornicata），现在解决的控制程序。首先，我们提出的模型，它结合了两个相互竞争的股票的动态。然后，我们使用该模型来分析各种假设下的渔业入侵物种控制的平衡，并评估入侵的社会成本。最后，我们提出了一套动态模拟有关正在进行的计划，强调其启动日期的影响，其整体的经济成果。
This paper presents a bioeconomic model of a commercial fishery facing biological invasion by an alien species acting as a space competitor for the native species. The model is illustrated in a case study of the common scallop fishery of the Bay of St-Brieuc (France), where biological invasion by a slipper-limpet (Crepidula fornicata) is now addressed by a control program. First we present the model, which combines the dynamics of the two competing stocks. We then use the model to analyze the equilibrium of the fishery under various assumptions concerning invasive species control, and to assess the social cost of the invasion. Finally we propose a set of dynamic simulations concerning the ongoing program, emphasizing the influence of its starting date on its overall economic results.
