Two porcine byproducts (hydrolyzed protein, PEPTEIVA and spray-dried plasma, APPETEIN, APC Europe) were used to substitute 5% fishmeal (FM) in a 48% protein-rich diet (7% FM) for gilthead seabream. Fish (initial weight = 60g) were on-grown for 3 months in 4x replicated 450L tanks connected to a recirculation system (IRTAmar©). At the end of the trial, samples of different organs (fillet, liver, plasma and skin) were taken to study the effect of these products on the composition and immune status of the fish. Growth in weight and length was also recorded.
