| The specific analysis of preys allows to determine the composition of cuttlefishes alimentary diet in natural conditions. This analysis based on exploitation of stomachal contents shows a majority of Fishes and Brachyura Crustaceans consumed. The alimentary diet with a Fish dominance in winter area (off Belle-Ille island) becomes a Crustacea dominance when adult cuttlefishes come in Morbihan Bay, in March, for reproduction. As for newly-born, they eat exclusively Crustacean Amphipoda and Macrura. |
