The effect of initial stocking density (8-47 thousand indiv./m3) on larval mass production of kuruma prawn was studied in ten trials. The larvae were reared for 24 days from the nauplius stage to the 15-16th day of the postlarval stage. The survival rates ranged from 0.29 to 0.84, and were above 0.5 in eight trials. The daily declining pattern of survival numbers in these eight trials colud be expressed by a logarithmic linear regression throughout the rearing period, thus the population decreased in a constant proportion. By a negative correlation between initial stocking density and survival rate, 24-day rearing obtains a survival rate of more than 0.5 with an initial stocking density of less than 30 thousand indiv./m3. Relationship between initial stocking density and harvested biomass per initially stocked individual (final individual fresh body weight×survival rate) showed a more significant negative correlation. The maximum yield was estimated as approximately 80g/m3 at an initial stocking density of 30 thousand indiv./m3. The actual value of the largest yield among these trials was 87g/m3 at an initial stocking density of 25 thousand indiv./m3.
