This paper attempts to examine the changes in surface water environment and community based coastal resources management activities in the Tam Giang Lagoon Central Vietnam. The results show that the lagoon s surface water has been polluted. BODs COD and nutrient concentration have increased in the lagoon s surface water environment. It proved that there was a present of organic substances. Due to the globalization of seafood products and changes in lagoon s water quality by aquaculture development the local government has issued many regulations to manage lagoon s resources. Among those policies the establishment of fisheries association and or self-management team is considered as appropriate solution to develop aquaculture and capture aquatic resources in the lagoon. However the benefit and power of the resource users have not been stipulated for both fisheries association and self-management team. Instead of this it is only member s responsibilities and duties in using lagoon s water surface areas. As a result most of resource users in the study area have not participated in these organizations as their members. The resource user must do all activities in relation to aquaculture by themselves without supporting from above organizations.
