An interactive model for the European anchovy from the Gulf of Cádiz

Abstract

This communication described a successful example of how models can provide com-prehensive outputs on the consequences of concrete management actions linking sci-entist knowledge with the experience and needs of stakeholders. A co-creation process with stakeholders is presented: Scientist from different fields (mathematics, biology, economy, political science) developed an interactive tool according to stakeholders needs and then they evaluate its performance. By using shiny R package, the interactive tool shows the outputs of a bioeconomicmodel for anchovy population dynamics in the Gulf of Cádiz under different manage-ment strategies defined by the stakeholders. The tool, available online at http://mareframe.mapix.com/gulf-of-cadiz-modelout-put.html, allows users to explore a range of relevant scenarios and how environmental forcing and fishing pressure impact on the resource and those people and societies ex-ploiting it. This in combination with its simplicity and user friendliness result in a tool that can be useful for the implementation of the ecosystem approach in fisheries man-agement.Stakeholders gave a positive feedback about the relevance of the tool as evaluated in a structured manner and state explicitly trade-offs among different management strate-gies; furthermore, they suggested future steps to a process that is expected to lead to a reconsideration of the present management strategy.
