Resumo: 	North-East Atlantic fisheries management goes towards a regionalisation, accounting for mixed fisheries technical interaction. Hence, understanding and assessing the spatio-temporal dynamics of exploited species and the fleets exploiting them is needed. This study aims to provide a tool to assess the effects of several management scenarii in the Bay of Biscay. lt fouses on North-east Atlantic northern hake stock (Merluccius merluccius) and the mixed demersal hake - sole (Solea solea) - Norway lobster (Nephrops norvegicus) Bay of Biscay fisheries.A Management Strategy Evaluation (MSE) framework has been developed, pairing a spatial northern hake stock assessment model, and an operating model (lSlS-Fish) simulating the Bay of Biscay mixed demersal fisheries.A Management Strategy Evaluation (MSE) framework has been developed, pairing a spatial northern hake stock assessment model, and an operating model (lSlS-Fish) simulating the Bay of Biscay mixed demersal fisheries.The spatial assessment model estimated northern hake abundance, recruitment and fishing mortality spatio-temporal variations, despite the estimation procedure sensitivity to initial point.The operating model incorporates all the current knowledge on the fisheries. lt has been calibrated following a multi-criteria approach, ensuring the reproduction of hake catch on 2010-2012. The Management Strategy Evaluation framework is not operational, although it highlighted discrepancies between both models dynamics at the fishery scale, and illustrated northern hake management through TACs potential effects on the fishery, in a landing obligation context. These results and improvement axes are discussed.
