In this study, in order to use prebiotics as one of the best solutions to maintain the health of farmed aquatic animals and increase their resistance against pathogenic instead of antibiotics, the effects of different levels of galatooligosaccharide (GOS) prebiotics on growth performance, biochemical body composition, and some blood serum indices were investigated. Therefore, two hundred and forty fish were randomly divided into 12 tanks with capacity of 100 L in four treatments with three replicates. Experimental treatments contained control, without GOS, first treatment: 1 % dietary GOS, second treatment: 2 % dietary GOS, and third treatment: 4% dietary GOS. Therefore, the fish were fed ad libitum two times per day for 8 weeks. The result showed that GOS improved growth and nutritional performance, body biochemical composition, and some blood serum indices in common carp. The treatment containing 2% GOS had the best performance in terms of final weight (32.58±1.08 g), food conversion ratio (1.57±0.09), protein content of body (14.78±3.77 %), serum total protein (4.66±0.18 g/dl), globulin (3.34±0.15 g/dl), and some other biochemical parameters of blood. Therefore, 2% dietary GOS had beneficial effects on performance of juveniles common carp fish.
