Abstract

The research goal is to assess the effect of the inclusion of different levels of lupine meal in the normally animal based diet of European sea bass (Dicentrarchus labrax) on the hypothalamic-pituitary-interrenal (HPI) axis activity by quantification of scale cortisol using ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) as biomarker for chronic stress in fish.
