Policy of Eutrophication Control in Cirata Reservoir, West Java, Indonesia

The aim of this research is to understand the dynamicsof ecosystem quality in Cirata reservoir that is utilizedfor fish net cage aquaculture (FNCA). The nutrientloading due to aquaculture and acceleratedeutrophication was modeled by a system dynamicsapproach. The system dynamics model was divided intoeutrophication and oxygen sub model. Both sub modelsimulations were run for 30 years and showeddecreased oxygen at epilimnion and hypolimnion, meanwhile nutrient, biomass of phytoplankton, and detritus increased. Acceleration policy simulationmean fish farming accelerated showing that oxygen tended to rise and nutrient, biomass of phytoplankton and detritus tended to decline.
