This study was proposed to control algal biomass in order to improve transparency of an artificial pond, using the manipulation of a pond ecosystem. Zooplanktons isolated from natural populations were tested for their algal clearance rate. The size of two ponds were 1,500 and 2,000 m^3, respectively. Average depth of two ponds was shallow around 1 m. Fish were completely excluded from Pond-A instead of introducing zooplanktons, and Pond-B was added fish with the same condition of Pond-A. Turbidity of Pond-A was less than 10 FTU and transparency was about 1 meter depth during the experimental periods(May-Aug., 1995). In contrast, Chl-a and turbidity of Pond-B were 40 FTU and 55㎍·1^-1 and transparency was mostly less than 20 cm during summer season.
