Abstract Oryzias woworae , one of the endemic ricefish species from Sulawesi, is threatened with extinction in their habitat. Domestication aquaculture way to preserve conservation these fish. The success factor for cultivation adaptation immature broodstock a controlled environment gonadal maturation. Adaptation performance after closed system transport first study O. at start an adjustment rearing. This aimed examine survival during transportation and post-transportation. has been transported 5 hours. used 2 plastic bags (separated male female) measuring 1 kg density 35 fish/2 L. Fish were adapted aquarium 20 days. result showed that could adapt well being days rearing Survival was 100% females 91.42% males.
