The purpose of this experiment was to know the influence of lowering salinity to growth, survival rate and performance zoea-megalopa of blue swimming crab. The experiment was done in concrete tank of 3,000 liters water provided with aeration system and initial zoea-1 density of 75 ind/l. Different lowering salinity for larva rearing were A: salinity for zoea-1 to megalopa stages of 32-34 ppt; B: salinity for zoea-1 to zoea-3 stage of 32-34 ppt and zoea-4 to megalopa stage of 28-30 ppt; and C: salinity zoea-1 to zoea-3 stage of 28-30 ppt and zoea-4 to megalopa of 24-26 ppt. The treatment A resulted highest survival rates, and growth rate of megalopa. The survival rate of treatmet A, B, and C were 23.08±4.01%; 17.23±3.41% and 11.54±1.41%, respectively
