Calibres and index of quality

The naming and classification of cupped oysters formerly given by the AFNOR 85344 norm is now determined by the central interprofessionnal agreement of the National Shellfish Committee, effective since 1st January 2001, and the specifications of the Protected Geographical Indication of Marennes-Oléron (PGI).

The classification of cupped oysters is fixed at the dispatching of the shipping company to the retail stage, according to their unit weight.

According to their name, the calibres correspond to the following table:
