Comparison of alpha diversity indices of the bacterial communities at different sites. (A) Comparison of the Sobs index of the bacterial communities at different sites, (B) comparison of the Shannon index of the bacterial communities at different sites, (C) comparison of the Chao index of the bacterial communities at different sites, and (D) comparison of the Simpson index of the bacterial communities at different sites. Higher Sobs and Chao values indicate a higher richness; higher Shannon and lower Simpson values indicate a higher diversity. Statistical significances between two sites were considered at * p < 0.05, ** p < 0.01, and *** p < 0.001 by Welch t-test. G: gill mucosae (G1–G4); C: intestinal contents (C1–C4); M: intestinal mucosae (M1–M4); S: stomach contents (S1–S4); W: stomach mucosae (W1–W4).
