This study focused on the physiological change of the shrimp, Litopenaeus vannamei postlarvae 15 stages, under different acclimation methods up to the endpoint of 4 practical salinity unit (psu). Besides using sea water as the control, two acclimation methods, fast acclimation (50% salinity reduction every 8 hours) and slow acclimation (50% salinity reduction every day), were adapted. Results show that the survival rate, glucose and blood uric nitrogen of each group were not significantly different. However, the ion profile differed according to the acclimation methods. Magnesium and sodium of shrimps acclimated to low salinity in both the methods, showed lower concentration than shrimps at 32 psu sea water. Especially, Na+ concentration, which directly influences the osmolality of shrimp, decreased sharply in the fast acclimated group during the first eight hours (from 32 psu to 16 psu). To reduce acclimation stress, it is recommended to take more than eight hours during the first step for reducing the salinity.
