The Marine Park has daily contacts with individual fishermen in 5 ports through patrol at sea, interviews and monitoring on landing, effort, catches. The social acceptance of the Park is an important factor, which has conditioned its success for more than 35 years. Professional fishermen feel integrated in the decision mechanism and the relationship between managers and them is based on trust and mutual exchange.

The protection and surveillance within the 2 no-take reserves is effective and led to a great increase in fish biomass and therefore to a reserve effect clearly observed: in 21 years, the mean weight of a fish increased by a factor of 2.5 and fishing captures have been multiplied by a factor of 5.

Recreational fishing is a fast-growing activity, with high performance technologies, which has never been taken into account in the management of fishery resources despite their catches are equivalent to those of professional fishing. Interactions with recreational fisheries seem to be higher, in the context of a global decline in the resource.

PMCB conducts several programs and monitoring that have became references in scientific litterature, particularly on the "reserve effect". Since its origin, the Park also created awareness and educational programs for scholars, with the implementation of one week training courses on field. More than 27.000 children have been made aware.
