^aThe variability of the fish gut microbial communities across treatment and ontogenetic stages was analyzed by PERMANOVA. The results revealed that the ontogenetic stages significantly influenced the gut microbial community composition for at least one sample (PERMANOVA pseudo-F value = 2.077, R² = 0.059, P < 0.001, number of permutations = 1,000). *, parameter with a significant P value.
