The results of the study are: [1] Revitalization of non productive fishponds at Mahakam Delta with silvofishery system was conducted by government and local community, applied Traditional Ditch Fishponds with three types of bakau planting site, i.e.: permanent flooded, periodically flooded and not flooded site. [2] Five major parameters of water quality in the 2 to 8 years ages silvofishery fishponds, (Temperature: 25 to 28 C; Transparency: 40 to 60 cm; pH: 6.7 to 7.36; Salinity: 13 to 20 ppt; Dissolved Oxygen: 3.2 to 5.7 ppm) are relatively stable and meets the quality standard suitability for cultivation of shrimp, milkfish and crabs.
