<![CDATA[Baung fish is one of the important food fish in Indonesia. Commercialization and intensive cultivation of this species is still limited, due to its inability to breed naturally in captivity, the provision of seeds for rearing mostly still relies on catches from nature. This research aims to determine the best dose of the ovaprim hormone for the development of reproductive performance of baung fish on the number of eggs from striping baung fish (THS), body weight gain and Somatic Ovi Index (IOS). Using 3 treatments and 3 repetitions, namely P1 ovaprim dose 0.4 ml/kg broodstock, P2 0.8 ml ovaprim dose/kg broodstock and P3 ovaprim dose 0.10 ml/kg broodstock. From the research results, it was found that the highest striping eggs were found in the P3 treatment with a total of 19321.90 eggs. Meanwhile, the lowest egg yield from striping was in treatment P2 with a total of 16,568.29 eggs. The increase in body weight in treatment P3 showed the highest results with an average amount of 21.66 grams, while the lowest test results were in treatment P1 with an average increase in body weight of 12.66 grams. The highest Somatic Ovi Index was P3, namely 7.58% and P1 was 7.11% as the lowest result in the Somatic Ovi Index test. In the P3 parent is a good dose to improve the reproductive performance of baung fish.]]>
