Stephane Panserat
Glucose metabolism in fish

Stephane Panserat
Research Director - INRA

After obtaining a PhD in Human Genetics and Metabolism in Paris (University Paris 7 - Jussieu), I integrated the INRA fish nutrition laboratory 20 years ago to study the nutritional regulation of intermediary metabolism in fish. I am currently involved in the understanding of the glucose use in carnivorous rainbow trout (a glucose intolerant fish species) using different approaches (molecular biology, signaling, biochemistry, nutrition).

Activities 

My Main Research activities:
My researches have the objectives to improve the basic knowledge about intermediary metabolism and nutritional physiology in fish species with a focus on glucose metabolism. The finalized impacts of my researches are for the aquaculture industry by trying to improve dietary carbohydrate use in fish through (i) development of adequate diet formulations based on the nutrient interactions, (ii) existence of fish lines showing different intermediary metabolism and (iii) development of the programming of metabolism after early biotic or abiotic stimuli. My favorite fish for my studies is rainbow trout but I am studying also other fish species such as Nile tilapia, European seabass, Atlantic salmon, gilthead seabream …

Other research activities:
Linked to my expertise in intermediary metabolism, I develop also some researches in collaboration with other colleagues about glucose metabolism and autophagy, glucose metabolism and epigenetics, energy metabolism and fish behavior (reproduction, migration, extreme conditions…), energy metabolism and growth hormone transgenic fish, nutritional programming in shrimps and ducks.
