Post‐larval Malaysian prawns( Macrobrachium rosenbergii ) were stocked in cylindrical tanks at densities ranging from 33 to 115 prawns/ m 2 (3.0 to 10.7 prawns/ft 2 ). Mean weight and survival measurements were taken at 2‐month intervals for a total grow‐out cycle of 6 months. The results show that populations of postlarvae (mean weight .016 g to .060g) grow to an approximate mean weight of 18 g within the 6‐month cycle. Mortality averaged 0.33%/day for the first 4 months and increased to 0.50%/day during the last 2 months of grow‐out.
