Figure 1.

Serum biochemical indices and lipid-metabolism-related gene expression of the liver in channel catfish (Ictalurus punctatus) fed the diets. (A) Triacylglycerol, TG; (B) total cholesterol, TC; and (C–E) lipid-metabolism-related genes (fas, acc, and srebp1). Data indicate the mean values of three replicate cages per treatment (three fish per replicate breeding barrel). Significance was evaluated by one-way ANOVA (p < 0.05) followed by Duncan’s multiple range tests. Values marked with different letters are significantly different between the treatment groups.
