The grading of live oyster is done for marketing and consumer preference purposes. According to French law, classifying oysters according to their individual weight is compulsory whether they are sold by the kilo or by the dozen. The photo shows the oyster grader as well as the graded oyster placed in the baskets.

According to the French grading system, (0) oyster is for largest size while grade (5) oyster is for the smallest size. In regard to the preference, French consumers prefer Grade 3 with average size of 66-85 g/piece and hence the too big or too small oysters are less accepted by consumers. The size grading is determined based on the length of the longest axis of the shell.
