<![CDATA[Jatigede Reservoir is one of the multi-functional reservoirs located in Sumedang Regency, West Java, Indonesia. The utilization of Jatigede Reservoir by the community caused ecological pressures that have resulted in a decrease in water quality and fisheries sustainability. The purpose of this study was to evaluate water quality parameters in Jatigede Reservoir to support a sustainable fisheries ecosystem. Sampling was done using purposive sampling and analysis using comparative descriptive. The results showed that the water temperature ranged from 26-29oC, pH 7.9-8.4, and dissolved oxygen 4-5.3 mg/L which still supports fisheries activities. The parameters of light transparency ranged from 0.19-1.1 m, total phosphorus 0.047 - 0.161, and chlorophyll-a 11 - 116 mg/m3 which exceeded the established quality standards. So it is necessary to manage and control pollution in Jatigede Reservoir to improve water quality and support the sustainability of the fisheries ecosystem.
