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.
Lemons and limes keep very well in the fridge unopened (maybe for two or three weeks), because the air does not dry it up or oxidize it. So, much better is to keep them unopened in the fridge and prepare them just before wanting to use it.
