| Sheltered by the Isle of Oléron, benefiting from the supply of fresh water from two rivers, the Charente and the Seudre, the Marennes-Oléron basin enjoys, in Charente-Maritime, a privileged topographical situation. Oyster farming, one of the first forms of marine aquafarming, represents the central business activity of this shoreline of the Charente, whose originality is to own more than 90% of the oyster pits currently listed in France. This peculiarity has been described by several authors: Moreau (1970), Gras (1976), Grelon (1978) and Marteil (1979). |
