ANOSIM and PERMANOVA analysis were based on Bray-Curtis dissimilarity for the comparison of bacterial community composition in the water, biofloc, and gut samples between control and treatment (permutation = 999). Each sample had six replicates (n = 6), except the water samples (n = 4) and biofloc samples (n = 2) in control group. P values adjusted by using the Benjamini–Hochberg algorithm <0.05 indicate significant differences.
