Insect meal has been increasingly considered as novel protein source in diets for different animal models, including fish. European sea bass is one of the most important fish species in Europe, particularly in the Mediterranean. Fishmeal is considered a premium protein source in diets for aquaculture fish. Thus, this study evaluated the impact of partial and total fishmeal replacement by an insect meal (defatted Tenebrio molitor larvae meal) on intermediary metabolism of European sea bass. After 16 weeks of feeding, the results obtained demonstrated that selected insect meal can be successfully used to replace 50% of fish in diets for European sea bass, without adversely affecting liver health or intermediary metabolism of nutrients. On the other hand, total fishmeal replacement by insect meal may compromise fish health in the long-term.
