BACKGROUND AND OBJECTIVES: As an urban coastal, Jakarta Bay faces significant pressure from human activities. Such pressure may result in the degradation of fish resources. The study objectives were to analyze the sustainability of small-scale fisheries in supporting the provisioning ecosystem services for coastal communities around Jakarta Bay.METHODS: The study site was the Jakarta Bay area. Data were collected from informants' assessments of the relevance of using coastal and marine areas to ecological integrity and provisioning ecosystem services. Fisheries data were collected through a combination of field observations, direct measurements, and surveys. The data collected included the species of fish caught, fish biomass, and the length and weight of each fish. Primary data collection was conducted through six sampling sessions over three months. Length and weight measurements were taken during these sessions focusing on five main fish species: Planiliza subviridis, Osteomugil speigleri, Arius maculatus, Gerres filamentosus, and Scatophagus argus. Data analysis for mapping and assessing provisioning ecosystem services was conducted by assigning relevance scores to the capabilities of ecosystems. Fish data analysis included growth parameters, mortality and exploitation rates, and the spawning potential ratio.FINDINGS: The assessment of provisioning ecosystem services in Jakarta Bay indicates that the balance between supply and demand for ecosystem services is favorable, with supply exceeding demand, particularly in mangroves area, water bodies, and marine resources. A total of 63 fish species were recorded at two fish landing sites. The population of Planiliza subviridis indicated that it is overfished, with exploitation rate value of 0.57. The spawning potential ratio of 0.15. The fishing mortality and natural mortality ratio values are 1.33 (length-converted catch curve) and 1.21 (Length-based potential ratio model), both exceeding the threshold of 1.0.CONCLUSION: Jakarta Bay provides ecosystem services to surrounding communities, particularly those in coastal areas. The fishery stock status of Planiliza subviridis indicates overexploitation. Therefore, effective fisheries management strategies are required to ensure sustainability and the optimal provision of ecosystem services in Jakarta Bay.
