A
total of 180 fingerlings (9.4 ± 0.3 g) were divided into three groups (G1–G3 of 20 fish per
group) in triplicate. G1 was fed a basal diet with no probiotic as the control group, while G2
and G3 were fed B. amyloliquefaciens spores at concentrations of 1 9 104 and 1 9 106
colony-forming units per gram (CFU/g) of feed, respectively.
