This study was conducted to determine the correlation between fecundity with length and weight of Macrobrachium rosenbergii at Balai Ringin and Maludam from August 2013 to January 2014. Prawns were collected using three layer gill net and a traditional method called ‘Selambau’ after an overnight of net deployment. A total of 34 berried female samples collected. The fecundity of 27 samples and fertility of 7 samples has been estimated through gravimetric and volumetric approach respectively. With the fecundity and fertility estimated, the relationships with the female body size have been expressed in a linear regression with positive correlations. The number of eggs produced from females of Macrobrachium rosenbergii in Maludam river is much higher of about 48% for weight dependent and 3% higher for length dependent than Batang Kerang floodpplain’s females. Meanwhile, the number of hatched larvae produced for Batang Kerang floodplain’s females is much lower than the number of eggs produced of the same area, of 32% lower for weight dependent and 37% lower for length dependent.
