Effets d’une mesure de gestion sur les résultats économiques des exploitants d’une ressource naturelle. Le cas de la pêcherie de bar commun (Dicentrarchus labrax) en France

The fishery for common sea bass (Dicentrarchus labrax) is the fourth most important French metropolitan fishery in value terms. Given its high market value, sea bass is targeted by a range of métiers, resulting in interactions between a large number of fleets. The annual contributions to catches and landings of each of these fleets are highly variable, as are their level of economic dependence towards the species. Sea bass is also and emblematic species for recreational fishermen. The aim of this thesis is to simulate the response of the French fishing fleets to introduction of alternative management scenarios for the sea bass fishery. Simulation results emphasize the diversity of anticipated impacts of alternative management scenarios from both a short-term and a long-term perspective, and the associated heterogeneity of economic incentives for different fleets to support these management scenarios.
