PROJECT NAISSAIN : STUDY OF THE PHYSIOLOGICAL STATUS OF SPAT OYSTERS
The objective of this project developed by the team 2 of BOREA Unit is to determine whether the physiological status of spat of the cup oyster Crassostrea gigas, influenced by the environment at different time of its life (life history traits), may ends up in conditioning the physiological status when animals are transferred to the foreshore and may thus potentiate responses of the individuals when facing increasing stress.
Anne-Sophie Martinez and her colleagues try to sharply qualify growth, reproduction, and energetic status of spat oysters in order to acquire, for the first time, a precise knowledge of their physiology in a large period of time going from metamorphosis to first sexual maturity. The diversity of spat used by professionals is taken into account by characterizing animals from different origins or which have been subject to diverse cultural and zootechnical practices. Understand, in spat, the link between life history of the animals, their physiological status and their response to stress is crucial in the actual context, in order to ensure the sustainability of a species of interest in aquaculture.
Project financed by the ‘Région Basse-Normandie’
