1Asterisks indicate statistically significant differences between uninfected and CEV-infected fish within the strain/group (*p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001). Different lowercase letters (e.g., a vs. b) indicate statistically significant differences at p ≤ 0.05 between the groups of uninfected fish. Different capital letters (e.g., A vs, B) indicate statistically significant differences at p ≤ 0.05 between the groups of CEV-infected fish. Statistically significant results are indicated in bold. Statistical analysis was performed using two-way ANOVA, with subsequent pairwise multiple comparisons using the Holm–Sidak test. The data are the means of n = 8 fish.
