oyster farming

Oyster farming is part of the local heritage and is quite an emblematic activity of the city and of the bay.

Oysters are hermaphrodites and reproduce in summer in water above 21 degrees. The spats that float in the water cling to the limed tiles that promote collection, which allows them to be detached 8 months later without damaging them: this is called detrocking. The spat are then placed in mesh pockets, which will be moved and returned to the oyster beds under the watchful eye of oyster farmers who leave the port daily on their barges. Against all odds, by filtering water and algae, the pearl of the Basin will reach maturity after three years.

At the oyster port, in the typical colorful and flowers-filled cabins, you will meet these men and women of the sea, and taste local oyster accompanied by a fillet of lemon and a glass of white wine !
