Abstract: In this research, domestication of Celebes rainbow fish (Marosatherina ladigesi) was started from the broodstock rearing, spawning and larval rearing. The purpose of this study was to determine the survival rate, fecundity rate, and gonad maturity levels of the broodstock that was fed live feed; Daphnia sp. , Chironomus sp. , and Culex sp. , whereas during the spawning period, the total number of eggs; the number of eggs hatching; egg incubation time; the number of unhatched eggs; and hatching rate were evaluated. The aim of study in the larval rearing is to determine the survival rate of the larva. Broodstocks of M. ladigesi were collected from Bantimurung river and Patunung Asue River of Maros regency; Jennae River and Gowalorong River of Pangkajenne Kepulauan regency; Asanae River of Bone regency. The result of research demonstrated that survival rates of broodstocks fed Dapnia sp. , Chironomus sp. , and Culex sp. were 91%, 86%, 81%, respectively. Broodstocks of M. ladigesi that were fed Daphnia sp. produced the highest number of eggs (849) , with the hatching rate of 70.77%, whereas the broodstocks that were fed Chironomus sp. produced 595 eggs, with the hatching rate of 67.11%, and the broodstocks that were fed larvae of Culex sp. obtained 565 eggs with the hatching rate of 65.14%. The incubation period was 8-9 days. The larvae were given nauplius of Daphnia sp. can achieve the survival rate of larvae was 38.31-39.02% until age 5 days, 62.44-71.67% at 10 days, 20-30 days after hatching, the survival rates ranged from 73.06-99.84%.
