Description :
The Cantabrian Sea ecosystem is described using a mass-balance model of trophic interactions, in order to know the impacts of the different fisheries that operate in this area. Estimation of trophic level of fisheries, transfer efficiency between trophic levels and mixed trophic impact analysis considering the fishery both as an impacting and impacted component are included. Also, we explore the potential relevance of simulating the effect of different fishing regimes on the ecosystem flow structure using Ecosim. Finally, Ecospace was used as an exploratory tool for the analysis of trophic relationships in the space and for the evaluation of the effect of some management options.
