Growth performances, survival rate, and biochemical parameters of Nile tilapia ( Oreochromis niloticus ) reared in water treated with probiotic

AbstractThe growth performances, survival rate, and biochemical parameters of Nile tilapia (Oreochromis niloticus) reared in water treated with probiotic were investigated. Samples of 225 Nile tilapia (5.8  ± 0.10 g) were reared for 90 days in three different treatments with three replications as the control group (no probiotic), and two test groups with probiotics consisting of yeast (Saccharomyces cerevisiae) (5.6  × 108 cfu g−1) andBacillus spp. (B. subtilis,B. megaterium, andB. licheniformis) (1  × 106 cfu g−1) added in water. Fish reared in water treated with probioticBacillus spp. and yeast (S. cerevisiae) showed a synergistic effect which significantly improved (p <  0.05) growth performances as final body weight (FBW), weight gain (WG), and average daily growth gain (ADG) compared to the control group with decreased aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels. There were no significant differences in malondialdehyde (MDA) level s in all treatments. Results showed that water treated withS. cerevisiae orBacillus spp. as a probiotic enhanced the growth performances of Nile tilapia and this method can be applied to increase tilapia production in the Thai aquaculture industry.
