Effect of supersaturated dissolved oxygen (DO) on relative mRNA expression levels of genes related to immune and stress tolerance of Litopenaeus vannamei. (a) Immune-related genes and (b) stress tolerance-related gene in hemocytes of L. vannamei after bacterin injection. Each bar represents mean ± standard error calculated from eight individual shrimp. One asterisk (*) indicates a statistically significant difference p < 0.05; Four asterisks (****) indicate a statistically significant difference at p < 0.0001.
