This research was carried out on 24 August until November 27, 2017 at the Balai Benih Ikan Pantai (BBIP) Biak Numfor Regency of Papua. The main objective of this research is to know the effect of the grant of salmon Gonadotropin-Releasing Hormone (GnRH s) against reproductive performance Humpback Grouper (Cromileptes altivelis). This research analyzed using descriptive method, which is the method used for outlining the figures obtained from the results of research. Research results are obtained in the form of reproductive performance of parent fish which include reproductive behaviour, maturity of sperm, as well as the maturity of the parent fish egg test. Research done by injecting salmon Gonadotropin Releasing-Hormone (GnRH s) contained in the parent fish to ovaprim test. Done with 2 and 3 repeated. First treatment using ovaprim with a doses of 0.6 ml/kg body weight of the fish and the second treatment using ovaprim with a dose of 0.9 ml/kg body weight of the fish. The reproductive behavior before spawning of parent fish that has been injected was observed. Then, do the calculation of the volume of sperm and fecundity. From this study, the results were there is the form of occurrence of reproductive behaviour on the parent fish that has been injected twice in a span of 2 months. However, such behaviour is not followed with the maturity of the gonads form sperm, whereas the derived presence of maturity on the parent fish egg.
