Dynamics of stable isotopes ratios (D13C and D15N) in different organs of Crassostrea gigas at two contrasted ecosystems: insights from growth and food sources
We studied the influence of food availability on the growth (whole body and organs) of the oyster Crassostrea gigas and on the dynamics of their d13C and d15N respective values. Juvenile oysters originating from Arcachon Bay were transplanted to two contrasting ecosystems, Baie des Veys (BDV) and Ra...
