Jatigede Resevoir has 4 122 ha with average of depth is 25.8 m. Its was multipurposed reservoir as hydropower electricity generator, flood control, irrigation and tourism. Social impact like livelyhood change from farmer to the other employment caused landuse change from rice field to reservoir area. Number of household were relocated 6 955 or 71.3% as farmer. One of  livelyhood alternative could be developed as the compensation is fisheries as capture and aquaculture activity. The aim of this study was to determine carrying capacity of aquaculture and capture fisheries with seed stocking. The data was collected on February  to May 2015. Total phosphorus initial was estimated from catchment area loading around the water body. Carrying capacity determination for aquaculture activity was calculated based on total phosphorus balances. The biomass cultured with single net for nile tilapia and common carp were 1668 and 1033 ton year-1, respectively. Number of fish stocking based on total phosphorus loading from aquaculture activity. The selected fish for stocking was milk fish and number of seed for stocking when the aquacultre activity optimally around 39 000 ind year-1.
