Popis: This study aimed to investigate the interactive effects of dietary carbohydrate levels and lipid sources on growth performance, tissue fatty acid (FA) profiles and intermediary metabolism of Megalobrama amblycephala . Fish (average weight: 37.98 ± 0.07 g) were randomly fed one of eight diets containing two carbohydrate levels (30% and 43%) and four lipid sources (fish oil, FO; soybean oil, SO; palm oil, PaO; and mixed oil (FO: SO: PaO = 1:1:1), MO) for 11 weeks. Little difference ( P > 0.05) was observed in growth performance and whole-body composition (except for lipid). However, energy retention, body lipid content, tissue lipid and glycogen contents and plasma metabolites concentrations all increased significantly ( P P P P P P P P P
