Abstract The effects of dietary glutathione on growth performance, skin antioxidant capacity, and immune responses and of juvenile taimen (Hucho taimen) were investigated. The experimental fish had a mean initial weight of 5.36 ± 0.13 g and were fed for eight weeks on diets containing graduated amounts of glutathione (0, 100, 200, 400, and 800 mg kg−1). After the 7 d lipopolysaccharide challenge, the immune parameters of the skin mucus, and antioxidant ability were determined. The treatment groups (400 – 800 mg kg−1) showed a higher survival rate and weight gain rate (P < 0.05). There were higher levels of skin mucus protein, lysozyme activity, and alkaline phosphate activity associated with dietary glutathione supplementation (P < 0.05). Dietary glutathione supplementation improved the minimal inhibitory concentration and antimicrobial activity of the skin mucus (P < 0.05). Fish in the treatment groups showed higher superoxide dismutase, glutathione peroxidase, and catalase activity (P < 0.05), whereas the malondialdehyde content was lower (P < 0.05) than those in the control group. Supplementary glutathione decreased the expression levels of TNF-α, IL1β, IL6, IL8 in the skin and ensured the relatively high expression levels of IκBα after lipopolysaccharide challenge. In conclusion, dietary glutathione (400 – 800 mg kg−1) improved the growth performance, decreased lipopolysaccharide-induced skin inflammatory response, indicating that glutathione has the potential anti-inflammatory effects for preventing inflammation diseases in juvenile taimen.
