This study was conducted to determine the effect of salinity which can produce the most fecundity and number of giant shrimp larvae ( Macrobrachium rosenbergii de Man). The experiment was designed using 24 units of randomized block design (RBD) using 20-30 g (B 1 ) and 40-50 g (B 2 ) heavy parent shrimp, with differences in salinity 0 pro-mile ( 0 / 00 ), 3 pro-mile ( 0 / 00 ), 5 pro-mile ( 0 / 00 ), and 7 pro-mile ( 0 / 00 ) which were repeated 3 times. The results showed that differences in salinity of the parent weight group (20-30 g and 40-50 g) had a very significant effect on fecundity and the number of larvae produced. The highest fecundity and production of shrimp larvae were obtained at salinity 5 Promil ( 0 / 00 ) in the parent weight group 40-50 g.
