Resumo: 	These last decades have been characterized by a great development of fishing techniques, contributing to the overexploitation of numerous marine fish stocks. In order to limit this collapse and to restore impacted communities, the implementation of management measures was necessary. Marine Protected Areas (MPAs), initially developed to protect remarkable habitats and associated biodiversity, are more and more used as a tool for spatial management of fishing activities, by adult export and/or larvae migrations from protected zones to surrounding fisheries.  The aim of this PhD was to use indicators and predictive models for evaluating the impact of the Bonifacio Strait Natural Reserve (Corsica) implementation on fish communities and the benefits of such management measures for the local artisanal fishery. Artisanal fishery catch data from south Corsica has permitted to highlight the indirect impact of recreational fishing on exploited fish communities structure and biomass. Although a decrease in fishing effort may contribute to increasing catches per unit effort (CPUE), the analysis using response groups helped us to reveal a distinct increase in the artisanal fishery catches for target species of spearfishing. We then developed a model and tested management scenarios for maintaining the spiny lobster resource, in decline in the reserve, into a sustainable exploitation way. Our results show that even if the BSNR legislation represents a benefit for many species, it is not sufficient to allow for the recovery of the red spiny lobster. Indicators issued from the ISIS-Fish model showed that higher restrictions on this resource access are necessary. After comparing various management measures, it appeared that the best compromise should be to authorize lobster nets use only during the summer season (July and August), for limiting the collapse of the population while offering a long term benefit for fishers, in the objective of sustainable fisheries.
