摘要： Six isonitrongenous and isolipidic diets were formulated to feed 360 fish (mean initial body weight: 6.06 & PLUSMN;0.02 g) with graded levels of sodium acetate (SA1 (0), SA2 (250 mg/kg), SA3 (500 mg/kg), SA4 (1000 mg/kg), SA5 (2000 mg/kg), and SA6 (4000 mg/kg)) for 8 weeks. The results revealed that weight gain rate, specific growth rate, and feed intake of golden pompano were significantly increased in SA3 and SA4 treatments (p < 0.05). Dietary SA level significantly improved lipid contents and gumminess of muscle (p < 0.05). Supplement levels of dietary SA significantly influenced plasma biochemical parameters containing triglyceride, glucose, high-density lipoprotein cholesterol, complements, and immunoglobulin M (p < 0.05). Appropriate supplement levels of dietary SA significantly increased enzyme activities of hepatic superoxide dismutase and total antioxidant capacity and decreased malondialdehyde contents (p < 0.05). Furthermore, appropriate SA levels downregulated the expression levels of Keap1, IL-8, TNF-alpha, and NF-kappa B genes and upregulated the expression levels of Nrf2 and TGF-beta genes of the spleen (p < 0.05). Excess SA caused negative effects for Trachinotus ovatus. The optimum supplement level of SA for juvenile golden pompano was evaluated to be 1423.67 mg/kg based on WGR.
