Figure 3.

Liver antioxidant indices of channel catfish (Ictalurus punctatus) subject to different treatment. (A) Malondialdehyde, MDA; (B) Superoxide dismutase, SOD; (C) Glutathione peroxidase, GPx; (D) Glutathione reductase, GR; (E) Glutathione, GSH; (F) Total antioxidant capacity, T-AOC. Data indicate the mean values of three replicate cages per treatment (three fish per replicate breeding barrel). Significance was evaluated by one-way ANOVA (p < 0.05) followed by Duncan’s multiple range tests. Values marked with different letters are significantly different between the treatment groups.
