Calibration Once the collected naissain, it is then appropriate to sort it according to its size. It is thus gauged, first once, put out of pocket, and installed on the ground or oyster beds, same. Seven months are passed before a new calibration. Meanwhile, the pockets will have been turned 4 times on average so to prevent that they do not push wildly through those.

Désatrocage One month separates us from now on installation from the tiles. At present, it is advisable to clean oysters with to separate them from various parasites such as naissain, sponges, herbes… The oysters are then désatroquées and the first oysters are ready with to be marketed.
Détrocage Six months later, the larvae became small oysters not larger than a nail of inch and must then to be withdrawn from these tiles.
