With completely randomized design (CRD) with afactor of four treatments and three replications. The treatments were P0 (0.9%sodium chloride injection of a dose of 0.2 ml / kg body weight of the mother), P1(ovaprim Injecting a dose of 0.3 ml / kg body weight of the mother), P2 (ovaprimInjecting a dose 0.5 ml / kg body weight of the mother), P3 (ovaprim Injecting adose of 0.7 ml / kg body weight of the mother).From the results of this study showed best treatment there in treatment P3with ovaprim dose of 0.7 ml / kg body weight, with an average latency time of7.07 hours, the number of eggs striping results as much as 365 grains / gramparent, the rate of conception by 77 , 16%, number of hatching at 77.75% and thenumber of survival by 77.98%. Water quality measurements during the study astemperature 28-300 C, pH 5-6 and 4.5 to 6.0 ppm dissolved oxygen
