The present study was designed to obtain performance data (growth, survival and yield) for white shrimp (Litopenaeus vannamei) intensively cultured in the indoor recirculating system. Intensive cultivation of white shrimp were conducted into two 20- tons tanks with an average weight of 0.39 g and density of 1,288 ind./m2. The growth rate, mean weight, harvest biomass, and survival rate were 0.63 g/week, 4.81 g, 2.96 kg/m2 and 47.7 %, respectively, as the pond shrimp harvested after 47 days. The water quality parameters, such as water temperature, salinity, pH value, and dissolved oxygen level, were maintained at 25.7 to 29.5°C, 23.1 to 30.5 ppt, 6.27-8.29, and 6.50-8.90 mg/l, respectively, during the experiment. The three kinds of nitrogen wastes, i.e., un-ionized ammonia-nitrogen (NH3-N), nitrite-nitrogen (NO2-N), and nitrate-nitrogen (NO3-N) were determined. Their ranges were from 0.00-0.03 mg/l, 0.06-7.24 mg/l, and 2.02-58.00 mg/l, respectively. The total viable counts and Vibrio viable counts of pound water had a level of 7.35 ×102 to 2.13 ×106 CFU/ml and 3.00 × 101 to 7.50 × 102 CFU/ml, and 1.13 ×105 to 1.10 × 106 CFU/ml and 1.48 × 103 to 3.38 × 105 CFU/g revealed in hepatopancreas, respectively.
