Note: Values are means ± standard error for ten replicates. Significant differences for means within experimental groups are indicated with different lowercase letter superscripts (p < 0.05, n = 10); Significant differences for means between head skin and caudal peduncle skin groups are indicated with different capital letter superscripts (p < 0.05, n = 10).
