A 56-day feeding trial was conducted to evaluate the effects of varying dietary lipid and starch levels on growth performance, biochemical components, and hepatic glycolipid metabolism in hybrid grouper. Nine isonitrogenous diets were formulated to contain three levels of lipid (6%, 10%, or 14%) and starch (14%, 21%, or 28%) using a 3 × 3 factorial design. Juvenile fish (initial body weight: 19.06 ± 0.03 g) were randomly allocated to 27 floating net cages (25 fish per cage, three replicates per
