Abstract: The present study was aimed to establish the information on the growth rates of L. vannamei for one crop in ponds with low saline with low stocking, low saline with high stocking and high saline with low stocking, high saline with high stocking densities. The average values of pH, salinity, dissolved oxygen, ammonia and temperature in ponds with low saline and low stocking density were 8.26, 7, 5, 0.4 and 31.1 respectively. Whereas in ponds with low saline and high stocking density were 8.33, 6, 4.5, 0.7 and 31.1. Similarly, the average values of pH, salinity, dissolved oxygen, ammonia and temperature in ponds with high saline and low stocking density were 8.09, 17, 4.9, 0.46 and 31.0 respectively. Whereas in ponds with high saline and high stocking density were 8.3, 18, 4.8, 0.91 and 32.0. It is evident from the present results that, the stocking density has inverse proportion with the growth. Low stocking density favours the production. In contrary high stocking density leads to lower the production rate.
