Spawning of pedih fish (Tor douronensis) is seasonal that occur twice a year. This causes limitation of mature broodstock. Therefore, the study was done to examine the effect of PMSG + antidopamin hormone in accelerating gonadal maturity female broodstock of pedih fish (Tor douronensis) at different concentration. This research used Completely Randomized Design (CRD) method, using 12 test fish with 4 treatments, namely treatment A (0 mL/kg fish), B (0.5 mL/kg fish), C (1 mL/kg fish), D (1.5 mL/kg fish). The ANOVA test results showed that induction of gonadal maturation in pedih fish (Tor douronensis ) using different concentration of PMSG + AD had a significant effect on broodstock weight gain (W), egg diameter (mm) and relative egg diameter (%/day) (P <0.05). The study indicated that the treatment C (1 mL/kg of fish) produced the highest value on the broodstock weight gain (0.17 kg), egg diameter (1.68 mm), relative egg diameter (8,03%/day).
