To evaluate the effects of taurine on the growth performance, hepatic glucolipids metabolism, and hepatic antioxidant capacities of largemouth bass (Micropterus salmoides), with an initial weight of (19.00±0.20) g were reared in cages (120 cm × 80 cm × 150 cm) for 8 weeks. The high starch control group (CON) was set at an 18% tapioca starch level, and 0.05% and 0.10% taurine (T0.05 and T0.1) were added based on this control group. The experiment consisted of three treatments, each with three replicates of 50 fish per replicate. Results indicated that taurine addition to high-starch diets significantly increased weight gain rate (WGR) and specific growth rate (SGR), while significantly decreasing liver crude fat and hepatic glycogen content. Intestinal amylase activity was also significantly elevated. Histological staining with H.E, PAS, and oil red O revealed that hepatocytes in the 0.1% taurine group were structurally intact, with reduced glycogen and fat droplets compared to the CON group. Serum glucose, low-density lipoprotein cholesterol, glutamic oxalacetic transaminase (GOT), and glutamate pyruvic transaminase (GPT) levels were significantly decreased after taurine addition, whereas alkaline phosphatase (ALP) and high-density lipoprotein cholesterol (HDL-C) levels were significantly increased. Hepatic G6Pase activity was significantly decreased in the taurine groups, while GK and PK activities were significantly elevated. The expression of genes related to glycolysis (pfk, gk and glut2) was up-regulated, while the expression of hepatic lipid synthesis-related genes (dgat1, lxr-1, srebp1, acc1α, fasn and gpat4) was down-regulated. In contrast, the expression of lipolysis-related genes (hsl, mgl, pparα, lpl, atgl and acadm) was up-regulated. Compared to the CON group, the expression of antioxidant-related genes (cat, sod, il-10 and tgf-β) was up-regulated in the taurine gropus, while nf-κb and il-8 expression was down-regulated. In summary, adding taurine to high-starch feeds can improve growth, regulate hepatic glucose-lipid metabolism, increase carbohydrate utilization, reduce hepatic glycogen deposition and lipid accumulation, and enhance the antioxidant capacity of M. salmoides. Under the experimental conditions, the recommended taurine addition in M. salmoides feed was 0.10%. This study provides a theoretical basis for taurine's role in regulating glucose and lipid metabolism and offers technical support for improving carbohydrate utilization in aquatic animals.
