In fish grouper escpecially humpback grouper culture, seed and broodstock quality and availability determine the production success. Main supply of wild broodstock still dominates grouper hatchery activities, therefore, the exploitation of the wild broodstock is very high. Efforts to use the supply of cultured broodstock through selection and breeding processes will greatly determine their culture success. The purpose of this experiment was to get seeds from the cross breeding between F-2 and F-0. The research used two (2) concrete tanks with volume of 75 m3 each. Each tank was filled with 20 fishes consisting of 10 fishes of F-2 and 10 fishes of F-0. The experiment was conducted the Institute of Mariculture Research and Development, Gondol, Bali. The result showed a good gonadal development and natural spawning of cross breeding between F-2 and F-0. Total number of eggs (1.320.000) was found the highest in May in tank A, while the highest fertilized eggs of 385.000 were found in June. The SSCP analyses showed no difference in genetic characters of broodstock from cross-breeding between the female parent F-2 and F-0 male parent. Keywords: Humpback Grouper, gonad, spawned, cross breeding, larvae

Research on Coral trout breeding has been started since 2002 at the Institute of Mariculture Research and Development and currently some hatcheries are being developed around the institute using natural broodstock. To promote the success on this breeding program, it is necessary to study the reproduction development of domesticated coral trout. The fishes were reared in floating net cage. Observation were conducted on 163 fishes in June 2013 with body weight range from 710 -2020 g (average of 1.393 g) and total length with range of 34-49.5 cm. Fishes were dissected and taken out their gonad for histology preparedness. Histology analyses found that there were 156 female, 2 hermaprodite, 2 male, and 3 unidentified fishes. All female fishes were on early gonadal development (stage I and II with gonadal maturation index of observed coral trout ranged from 0.1 to 1.83). Further analyses showed that several different stages of gonad were found in the same gonad and concluded that coral trout was multiple spawnning order (asynchrounous). Based on the data above, it was concluded that gonad maturation of Coral trout is able to develop in domestication system in floating net cage. Keywords: Gonad, Coral trout (Plectropomus leopardus), hystology, floating net cage
