Nile tilapia (Oreochromis niloticus) is one of the aquaculture commodities in Indonesia. One of the challenge of fish production is the high cost of the feed. Thus, the efficiency of fish feed should be improved by adding supplementation that could promotes fish growth and health. This study aimed to to investigate the effects of eco-enzyme supplementation into commercial feed on growth, feed utilization and survival rate in O. niloticus. The fish juvenile which used in this research was 4.95±0.95 g which obtained from the local fisheries in Yogyakarta. The research done using completely randomized design (CRD), four treatments, and three replications. The treatments were different eco-enzyme supplementation in commercial fish feeds: A: control/commercial feed, B: commercial feed supplemented with 20mL eco-enzyme, C: commercial feed supplemented with 40mL eco-enzyme, and D: commercial feed supplemented with 60mL eco-enzyme. Relative growth rate, food conversion ratio, feed efficiency, protein efficiency ration, and survival rate were used as parameters tested. The results showed that feed supplemented with 40ml eco-enzyme gave best effect of relative growth rate (RGR), feed conversion ratio (FCR), feed efficiency (FE), and protein efficiency rate (PER) of fingerlings tilapia fish. While highest survival rate (SR) were obtained by the addition of 60 ml of eco-enzyme.
