The commercial aquaculture of seurukan fish (Osteochilus jeruk) is common in Indonesia; however, seed availability from the wild is limited. Therefore, induced breeding technology in seurukan fish using synthetic reproductive hormones is crucial. This study evaluated the efficacy of five different types of synthetic reproductive hormones and their corresponding doses on the reproductive performance of seurukan fish in captivity. The methodology consisted of two experiments; first, four types of synthetic reproductive hormones were tested: ovaprim, ovaspec, human chorionic gonadotropin (HCG), and ovalumon. Second, several doses of ovaprim hormone were tested with doses of 0.25, 0.50, 0.75, and 1.0 ml kg-1 body weight. The results showed that ovaprim, ovaspec, and HCG successfully induced ovulation and spawning in seurukan fish. The hormones significantly affected the latency period, number of eggs released, fertilization, and survival rates (P<0.05), but did not significantly affect the hatching rate and survival of larvae (P>0.05). Ovaprim produced better egg quality compared to ovaspec and HCG. In the second experiment, the results showed a significant difference in the latency period and egg size (P<0.05) of fish treated with varying doses of ovaprim hormone. The hormone doses did not significantly affect the number of eggs, hatching rate, fertilization rate, survival rate, or larval survival (P > 0.05). The dose of 0.5 ml kg-1 BW of ovaprim produced the best results. Therefore, a dose of 0.5 ml kg-1 BW was recommended as an effective dose for induced spawning and seed production of seurukan fish.
