The National Park of Guadeloupe Island (Lesser Antilles) was created in 1989. From June 2009, the park is composed of multipolar cores (21,000 hectares), a partnership zone (90,000 ha) and a sustainable development marine zone (130,000 ha). The National Park has a territory charter defining the objectives for all these areas. Sixteen municipalities have subscribed to this project. The inhabitants of some of these municipalities have denounced the overexploitation and the non-selective methods of capture for Cardisoma guanhumi and Ucides cordatus. They were once consumed mainly during Easter and whit periods. They are currently fished all year round and their populations are threatened. In this context, the National Park proposes a management model to protect these crabs.
