Abstract
This research was aimed to determine the effect of nitrifying bacteria to improve the water quality in Penaeus monodon culture. The study consisted of two major step, application of nitrifying bacteria and measurement of biological and physicochemical conditions. Water quality parameters in all treatments with nitrifying bacteria addition remained within the tolerance range for tiger shrimp culture (concentration of nitrate, nitrite, ammonium, DO, and pH). The addition of nitrifying bacteria one week before culture was able to control water pathogenicity V. parahaemolyticus
