Abstract
This study was conducted to investigate the effects of puerarin on growth, digestive enzymes, antioxidant capacity, immunity and liver health of Acanthopagrus latus. Four diets were formulated: a control diet (C) and C supplemented with 200, 400, and 600 mg/kg puerarin (CP2, CP4, and CP6, respectively) and a eight-week feeding trial was conducted of fish. The results showed that the addition of 400 mg/kg puerarin significantly increased weight gain (WG), specific growth rate (SGR), and decreased the feed conversion ratio (FCR) compared to C group. Dietary supplementation with 600 mg/kg puerarin significantly increased lipase (LPS) activity compared to the C group. The addition of 200 mg/kg puerarin significantly reduced low-density lipoprotein cholesterol (LDL-C) and 400 mg/kg puerarin significantly reduced total cholesterol (T-CHO), triglycerides (TG) and HDL-C compared to the C group. Dietary supplementation with 400 mg/kg puerarin significantly increased serum and liver glutathione (GSH) activity and decreased malondialdehyde (MDA) content compared to the C group. Addition of 400 mg/kg puerarin significantly increased liver catalase (CAT) activity compared to the C group. Supplementation of 600 mg/kg and 400 mg/kg of puerarin significantly increased serum alkaline phosphatase (AKP) and lysozyme (LZM) activities, respectively. Compared to the C group, the addition of 200 mg/kg of puerarin significantly increased the activities of acid phosphatase (ACP) and alkaline phosphatase (AKP) in the liver. CP4-feeding significantly upregulated the expression of nrf2, ho-1, and gclc while downregulating the expression of keap1 compared to the C group. The addition of puerarin significantly reduced the expression of tnf-α and il-6 compared to the C group. Supplementation of 200 mg/kg puerarin significantly reduced the expression of bax compared to the C group. In conclusion, dietary supplementation with puerarin had positive effects on the growth, digestive enzymes, antioxidant capacity, immunity, and liver health of fish, particularly at 503.5 mg/kg.

期刊介绍:
Aquaculture Reports will publish original research papers and reviews documenting outstanding science with a regional context and focus, answering the need for high quality information on novel species, systems and regions in emerging areas of aquaculture research and development, such as integrated multi-trophic aquaculture, urban aquaculture, ornamental, unfed aquaculture, offshore aquaculture and others. Papers having industry research as priority and encompassing product development research or current industry practice are encouraged.
