Effects of fasting and re-alimentation on gill and intestinal morphology and indicators of osmoregulatory capacity in genetically selected sea bass (Dicentrarchus labrax) populations with contrasting tolerance to fasting
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.
