Finfish should be stored in the refrigerator and used within 1 to 2 days after purchase. Itâs a good idea to store it on ice in the refrigerator to keep it as cold as possible. If the fish wonât be used within 2 days, wrap it tightly in moisture-proof bags (so the fish wonât dry out) and store it in the freezer.
