Freshly shucked oysters can be immersed in water and placed in shallow, air-tight containers in the freezer. Freezer temperatures should be below zero degrees Fahrenheit. Oysters can be frozen for up to three months.
Unlike most shellfish, oysters can have a fairly long shelf life of up to four weeks. However, their taste becomes less pleasant as they age. Oysters should be refrigerated out of water, not frozen, and in 100% humidity. Oysters stored in water under refrigeration will open, consume available oxygen, and die.
