The data shown are the mean and standard deviation. a–d Means bearing different superscript letters within the same row are significantly different (p < 0.05). MSD = low stocking density, HSD = high stocking density, T3 = triiodothyronine, T4 = thyroxine, MDA = malondialdehyde, SOD = superoxide dismutase, GPx = glutathione peroxidase, CAT= catalase.
