文摘

This study focused on differences observed in the gills and intestine of two selected populations with contrasting tolerance to fasting. Two selected seabass populations with contrasting tolerance to fasting were studied: bad fasters being also fast feeders. During feeding, these two phenotypes have different physiological optimization / prioritization and energetic benefits. We evidence that the fast feeders (F +) are also the bad fasters.
