A bio-economic analysis of experimental selective devices in the Norway lobster (Nephrops norvegicus) fishery in the Bay of Biscay ArchiMer
Raveau, Adriana; Macher, Claire; Mehault, Sonia; Merzereaud, Mathieu; Le Grand, Christelle; Guyader, Olivier; Bertignac, Michel; Fifas, Spyros; Guillen Garcia, Jordi.
Several fleets with various fishing strategies operate as a mixed fishery in the Bay of Biscay. Among the main fleets, bottom trawlers target Norway lobster (Nephrops norvegicus) and, together with gillnetters, they also catch hake (Merluccius merluccius). Trawling leads to average-size catches that are below the minimum landing size (MLS); such catches are discarded since they cannot be sold. These discards result in negative impacts on stock renewal, as most of them do not survive. This also results in an economic loss for both bottom trawlers and gillnetters since these discards represent a future loss of rent. This study, based on the 2009 and 2010 selectivity experiments at sea, assesses the short- and long-term bio-economic impacts of four...

Investigating trade-offs in alternative catch-share systems: an individual-based bio-economic model applied to the Bay of Biscay sole fishery ArchiMer
Bellanger, Manuel; Macher, Claire; Merzereaud, Mathieu; Guyader, Olivier; Le Grand, Christelle.
An individual-based bio-economic model (IAM) is presented and applied to the Bay of Biscay sole fishery to investigate alternative quota management systems from a multi-criteria perspective. For this study, the model integrates several institutional arrangements related to catch share management. The current French co-management system with non-transferability of quota is compared to an alternative ITQ system in a context of transition to maximum sustainable yield (MSY). Trade-offs between ecological and socio-economic impacts are highlighted and the effectiveness of governance scenarios is discussed in regard to the challenge of capacity adjustment. Results emphasize that the introduction of ITQ is expected to reduce by 40% the number of vessels in the...

The role of technical protocols and partnership engagement in developing a decision support framework for fisheries management ArchiMer
Macher, Claire; Bertignac, Michel; Guyader, Olivier; Frangoudes, Katia; Fresard, Marjolaine; Le Grand, Christelle; Merzereaud, Mathieu; Thebaud, Olivier.
In the context of the Common Fisheries Policy Reform, the implementation of multiannual management plans for fisheries and the annual quota negotiations between EU member states has generated a growing demand from stakeholders and managers for integrated advice that goes beyond the usual biological advice. This has led to the emergence of bio-economic tools and methods for the comparison of the biological, economic and social tradeoffs associated with alternative options for fisheries management. A Decision Support Framework (DSF) has been developed in this context, with the objective to tackle technical and methodological challenges to be able to provide bio-economic advices to support decision at national and European level. It is based on a partnership...
