| Ce document présente une des tâches en économie réalisée dans le cadre du projet ANR Comanche (Interactions écosystémiques et impacts anthropiques dans les populations de COquilles Saint-Jacques de la MANCHE). Ce projet d’une durée de trois ans (2011-2013) a vocation à améliorer la connaissance de la coquille St Jacques à l’échelle de l’ensemble de la Manche, à travers une approche écosystémique des pêcheries, en faisant appel à un large éventail de disciplines scientifiques (physique, chimie, génétique, écologie, géostatistique, modélisation, économie….). La tâche en économie de ce projet (tâche 9) vise à étudier les relations entre les systèmes de régulation des deux principaux gisements (baie de St Brieuc et baie de Seine) et les performances... |

| The aim of this article is to explore, through a hedonic approach, the factors that might explain the price variability for the French-managed fishery of scallop at primary fish markets. In addition to factors classically identified in the current literature like intrinsic product characteristics or markets situation, the characteristics of operators are tested. The relationships of loyalty between sellers and buyers, and market assiduity are notably considered. |

| La science économique s’attache à analyser l’allocation des ressources rares à des fins alternatives. Pour qu'elles soient utilisées le plus efficacement possible, l’économie s’est dotée d’outils d’analyse et d’évaluation, qui sont appliqués au domaine de l’environnement et des ressources naturelles ainsi qu’à l’évaluation des politiques publiques. |

| There are two ways of assessing the costs of environmental degradation: as the costs associated with the loss of benefits resulting from the degradation of natural capital, and as the maintenance costs required to compensate for the actual or potential degradation of natural capital. The first of these methods is based on the Total Economic Value (TEV) of benefits forgone because of the depletion of ecosystem services delivered by marine biodiversity. The second method is based on the costs required to maintain a good state of marine biodiversity, one which makes it possible to deliver ecosystem services. This paper gives an illustration of this second approach. It details how these maintenance costs have been calculated in the initial assessment of the... |

| 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... |
