Effect of dietary pistachio shell powder (PSP) inclusion on total phenolic compound (TPC) concentration (a) and total antioxidant capacity (TAC) (b) in the serum of rainbow trout fed fishmeal or plant meal-based diets at different PSP inclusion levels (0%, 0.5%, 1%, 2%). p-values indicate the significance of differences between PSP inclusion levels within each diet type (one-way ANOVA). CRE—μM copper-reducing equivalent, which is proportional to TAC.
