Data are provided as mean ± SD (n = 9 fish per treatment). There is a statistically significant difference (P < 0.05), between the means of identical rows denoted by distinct letters. Means in rows with identical lettering do not substantially vary (P > 0.05). Significantly different (P < 0.05) are the main effects of time on the means of rows with different capital letters. SOD, superoxide dismutase; POD, peroxidase; CAT, catalase.
