Larval fecundity which expresses the number of larvae produced per gram of female, is a variable that directly describes the quantity of larvae produced per unit weight of the broodstock. The objective of this study was to evaluate the number of larvae produced per unit weight of the broodstock (fecundity larvae) at base population (F0) of fast growth and late sexual maturity.

Both of selected broodstock and controlled population were maintained in the spawning pond size of 200 m2. The ratio of male: female was 1: 1.  Commercial feed with a crude protein content of 26% has been used with  the feeding rate as much as 3% of the prawn biomass.  The mean of larvae produced on a selected population was 21.092 larvae and it was significantly different from the controlled population that was 14 972 larvae. Larval fecundity in both populations showed significantly difference at the 95% confidence level. This indicates that the broodstock of selected populations has a good reproductive performance. The broodstock in a selected population showed that the reproductive performance was not impaired, so it can be used to generate  the next generation.
