The culture of shrimp received maximum importance due to its unique taste, high nutritive value and persistent demand in world market. In the present study an attempt has been made to culture the giant tiger shrimp, P. monodon . The salinity of the culture pond was ranging between 20-28 ppt and pH was 7.5 to 8.8. Minimum 3.9 ppm dissolved oxygen and maximum 4.2 ppm was recorded during the culture period. The temperature was ranging between 27 to 30°C and the transparency was 35 to 50 cm. The culture was done for 133 days and the average body weight of the harvested animals is 34.1 g. The total production was 1,886 kg and the survival rate was 87%. The FCR was 1.28 and the net profit was calculated as Rs. 3, 69,127. So it is confirmed that 9.8 m is an ideal stocking density for the culture of P. monodon as evidenced from the net profit Rs. 3, 2 69,127. To get this profit, proper water quality management and feed management is essential.
