Abstract: The purpose of this study was to analyze the survival and specific growth of milkfish after being given various prebiotics from the types of beans in the feed. Spread with a density of 15 birds/aquarium with a size of 50 x 45 x 45 cm filled with water with 15-20ppt salinity. Fish are kept for 60 days and fed 5% body weight/day. The study was designed in a completely randomized design with 5 prebiotic treatments from legumes, soybeans, peanuts, green beans, kidney beans, and controls. The results showed that various prebiotics in a feed from legumes was significantly (p <0.05) on survival and specific growth (% / day).
