The separate shrimp-mangrove system at the Tamgiang 3 FFE [forestry-fishery enterprise] has the highest BCR [benefit cost ratio]. However, the five-hectare integrated mangrove-shrimp (FS 5 ha) system at the 184 FFE has the highest net return. The present mangrove management system in the Kienvang FFE seems to be the most sustainable, followed by the Tamgiang 3 FFE and FS 5 ha system of the 184 FFE. Furthermore, the 20 years rotation system with six harvesting series in the best silvicultural system for mangrove forests combined with shrimp farming in the study area. The present mangrove management system in the Mekong Delta appears effective because during the past five years, mangrove destruction has been controlled and several thousand hectares of bare lands have been reforested. The educational attainment of the households in the study area is generally low (5 to 6 years) which may limit their capability in adopting new technologies. Many households are sparsely settled throughout the mangrove areas. As such, they have less access to social services, among others. Farmers and television are the main sources of technical information among the farmers. Majority of the farmers are well informed on the importance of protecting and conserving the mangrove forests. However, they are not well-informed on shrimp culture techniques. The annual gross income of the mangrove forest-fishery farmers ranged from 2.8 to 104.7 million VND (201 to 7,479 USD). This gross income is low compared to other countries. The household income of the farmers appeared insufficient for their production investment and family basic living expenses. There are both advantages and disadvantages of the mangrove management strategies implemented in the four FFEs
