Compared to Fishmeal, Dietary Soybean Meal Improves the Reproductive Performance of Female Yellow Catfish (Pelteobagrus fulvidraco) Broodstock

Figure 4

Effect of different dietary protein sources on hepatic lipid metabolites of female yellow catfish broodstock based on the lipidomics approach. (a). Analysis of mean peak intensity of main class lipid molecules; values are expressed as (); different letters represent the statistically significant differences (). (b). PLS-DA discriminant analysis model score map. (c). Volcano plots of all identified lipid metabolites from lipidomics; different colors were used to represent downregulated (blue), upregulated (red), or nonsignificant (gray) metabolites.(d). Heatmap of differential subclass lipid molecules. score normalized ionic strength for each metabolite was represented by different colors: high (red), low (blue), or average (white).
