Marine protected areas (MPAs) have been created to preserve biodiversity and manage human activities. Unfortunately, many of these MPAs have failed to accomplish their goals because fishermen well-being was neglected. Thus, taking in account fishermen perceptions will undoubtedly contribute to MPAs success and durability. In this paper we focused on assessing fishermen perception of the future marine protected area “Jbel Moussa” situated in northern Morocco. Results showed that the majority of fishermen affirm that the set of this MPA will lead to a reduction in catches and to an increase in costs and charges. They affirm that it will have to be managed jointly with locals according to “top-dow bottom up” management approach to make it reach its goals,this will avoid conflicts likely to occur during the application of the regulations specific to the future MPA. In order to work for the success of the future MPA, fishermen must take part in the management process. The authorities have to organize meetings with fishermen to discuss about benefits, mode of governance, zoning, etc… Knowing all these factors, we can move towards better management of resources, finding a balance between preserving the marine ecosystem and the well-being of fishermen.
