Oyster Sizes and Grades
Shucked Oysters
Shucked oyster sizes are based upon the number of individual oysters within a given volume. The largest size of shucked oysters are called "counts", followed by "extra selects", "selects" and "standards" and rarely "very small". The following list specifies typical numbers of individual oysters within a given volume for the most popular sizes.
Counts: 160 oysters or less per gallon
Extra Selects: 161-210 oysters per gallon
Selects: 210-300 oysters per gallon
Standards: 300-500 individuals per gallon
Very Small: over 500 individuals per gallon
Oysters in the Shell
Oysters are sold raw in the shell in a number of ways. Many retail seafood markets offer oysters by the piece. Other measurements include by the dozen, peck, bushel or 100 lb bag.
A bushel is a U.S. and imperial unit of dry volume, equivalent in each system to 4 pecks, 8 gallons, 32 quarts.
a United States bushel = 2150.42 cubic inches; an Imperial bushel = 2219.36 cubic inches.
Sizes of raw oysters in the shell vary widely depending species and location. A basic rule of thumb for most American oysters is that there are roughly 100 oysters per bushel; 25 per peck.A bushel of oysters will feed, on average, between 4 and 6 people.
