欧洲联盟海洋战略框架指令（MSFD）包括受捕鱼活动影响的良好环境状况（GES）的四个描述符。这些描述符是：生物多样性、鱼类资源、食物网和海底完整性。本文展示了这些描述符如何与生态模型中的变量相关联，以及生态模型如何用于分析根据生物经济标准估计的捕捞压力是否在一般可持续限度内。本文提出了一个使用两种模型对东波罗的海鳕鱼渔业进行这种分析的例子：生物经济模型和生态模型。这些模型是根据历史数据校准的。MSFD指定的描述符与模型中可用于分析的变量之间的映射是不完整的，例如遗传和空间结构不包括在模型中。这些模型可以战略性地使用，提供对预期的相对变化的定性理解。
The European Union Marine Strategy Framework Directive (MSFD) includes four descriptors of Good Environmental Status (GES) which are affected by fishing activity. These descriptors are: biodiversity, fish stocks, foodweb, and seabed integrity. This paper shows how these descriptors can be related to variables within an ecological model and how an ecological model can be used to analyse whether the fishing pressure that is estimated based on bioeconomic criteria is within general sustainable limits. The paper presents an example of such an analysis of the Eastern Baltic cod fishery using two models: a bioeconomic model and an ecological model. The models are calibrated based on historic data. The mapping between the descriptors specified by MSFD and variables available for analysis in the models is incomplete, e.g. genetics and spatial structures are not included in the models. The models can be used strategically, providing a qualitative understanding of the anticipated relative changes.
