Indonesian freshwaters are rich in fish biodiversity, one of them is javaen barb. In terms of domestication, it is important to ensure the fish breeding and larval rearing in ex-situ environment. Therefore, studies on artificial spawning are needed to strengthen the information about reproduction of javaen barb in ex-situ environment for domestication and aquaculture purposes. This study aimed to evaluate the reproductive and larval performance in artificially spawned javaen barb within two populations. Broodfish were obtained from West Java (Tasikmalaya and Cianjur population), kept on the fish nets (2×2×1 m) inside the large ponds for two months of adaptation. Broodfish were attached by RFID chips and periodically observed their size and gonad maturity level. Ripen broodfish were artificially spawned. Several reproductive parameters were observed during the experiment, such as egg diameter, fecundity, fertilization rate (FR), hatching rate (HR), and hatching time. Moreover, larval performance was also observed. The results showed that javaen barb successfully spawned with 11 hours of latentcy period. Javaen barb from Tasikmalaya population had a significantly higher fecundity than that of the Cianjur population. Meanwhile, other parameters observed in relation with reproductive and larval performance were not significantly different.
