Figure 1.

Alpha diversity indices (Shannon, Simpson, Pielou_e) in shrimp farm samples with different oxygenator conditions. Boxplots depict the medians (central horizontal lines), inter-quartile ranges (boxes), and 95% confidence intervals (whiskers). p-values are based on the Kruskal–Wallis test. Asterisks indicate statistically significant differences between pairs of values (* p < 0.05). (A) Bacterial diversity index in water. (B) Bacterial diversity index in sediment. (C) Diversity index of gut bacteria.
