Resumo: | Six Rajidae stocks (Raja clavata, Raja brachyura, Raja montagui, Raja microocellata, Leucoraja naevus and Raja undulata) are currently exploited in the English Channel and North Sea area (ICES divisions 3a, 4 and 7d) and subject to a TAC regulation. This TAC is set based on monospecific approaches (abundance indices) when mangement is complex based. However, stock status disparities exist between these species. In this context a multispecific MSE (Management Strategy evaluation) framework has been developped based on DLMTool package from R. The main objective was to estimate the complex management impact at the different steps of stocks management (data collect, assessment, management measures implementation). The species species assessement and  management scenario was the best performing one, in term of long term stock biomass as well as yield. However, species specific assessement associated to complex management performances were more contrasted than the performance metrics of a complex assessment and complex management scenario.
