This study aimed at characterizing the diet of the oyster Crassostrea gigas along an estuarine gradient in the Bay of Brest (France), through stable isotope (delta C-13 and delta N-15) measurements in primary producers and wild oysters. The contribution of different potential food sources to the die...
