The participatory maritime surveillance system of the PNBA is the result of a tripartite partnership, which integrates the resident Imraguen population, alongside the park managers and the coast guards (GCM). This system aims to control the entry of boats from outside the PNBA, particularly for motorized pirogues, which have been prohibited within the park since its creation in 1976.The respect of the fishing seasons calendar is today considered a successful model in the West African sub-region. The experience of the PNBA has benefited the Regional Network of Marine Protected Areas in West Africa (RAMPAO), notably through technical support missions and exchange visits. The functioning of the PNBA's participatory surveillance mechanism has as a central feature the representativeness of three entities on board each surveillance vessel: a PNBA agent, a GCM agent, and a representative of the Imraguen population. It has so far contributed to the reduction of illegal exploitation of resources, through the application of management rules agreed upon jointly with the resident population
All sectors are represented at committee meetings: fishermen, fish merchants, women processors, and boat carpenters. In addition, on board the surveillance boats patrolling the waters of the park, a representative of each of the three parties of the in the maritime surveillance is present: a PNBA officer, a coast guard officer, and a representative of the local population (designated by the population itself).
The presence of these three representatives on board each surveillance vessel has proven to be facilitating interventions, reducing the potential risks of corruption by fishermen who are boarded in the event of an infraction.
