Among them Nha Trang bay had longer history of marine tourism starting with inshore development and expanding to islands in and around the bay. Tourist activities in Cu Lao Cham islands and Ninh Thuan were developed in linkages with MPA development and management. Meanwhile Phu Quoc had become a new destination and drawn huge investments for extensive development of tourism in the islands. Economic value that was brought from use of coral reefs for tourism has increased significantly. For example the payment of entry fee to Cu Lao Cham MPA has quickly increased year by year reaching approximately 700 000 USD in 2018 and that in Ninh Thuan around 50 000 in 2017 and up to 200 000 USD in 2018. Reclamation for infrastructure building on inshore land and islands was considered as a serious impact resulting in loss of terrestrial and underwater habitats . loss of Melaleuca forest in Phu Quoc islands or seagrass beds and coral reefs in Nha Trang bay and i ncreased sediment loading to coral reefs. Overexploitation of living resources for high food and souvenir demands occurred at all areas leading to modification of communities poorness and uncertainty for resource recruitment. Among these .
