Mangrove ecosystems have multiple functions which include economic and environmental functions. A well-proportionated mangrove ecosystem management would benefits optimally. The purpose of this study was to determine the most appropriate scenario for managing mangrove ecosystem side by side with aquaculture through an economic valuation to find out the management value with which the scenario is most beneficial both ecologically and economically. The data were collected through interviews using questionnaires, literature review, and institutional data. The data were processed through an economic valuation of total economic value (TEV) and cost-benefit analysis (CBA). The data were analysed spatially and descriptive-quantitatively. The total economic value of the mangrove ecosystems was USD 6.73 million. The benefit and costs of managing mangrove ecotourism were USD 3,930.74/ha/year and USD 1,701.69/ha/year, respesctively, where as the benefits and costs of managing ponds were USD 150,433.85/ha/year and USD 55,269.46/ha/year, respectively. The prioritized scenario of mangrove ecosystem management was a scenario with an ideal proportion of mangrove and ponds areas, i.e. 50:50 and total ecological and economic benefits for a period of 25 years of USD 19.17 million.
