Thèmes de Recherche.
My research activities fit into a general problematic, which aims at studying the physiological and behavioural responses in fish facing modifications in external (e.g. temperature, oxygen) or internal factors (e.g. size). Considering the whole organism, I employ an eco-physiological approach and tackle more particularly energetics.
