Fish can be refrigerated for 1-2 days and frozen for 1-3 months. Before it is stored in the refrigerator, the internal organs and scales should be removed, washed, cut into fish pieces and put into fresh-keeping bags to avoid the spread of fresh fish smell. Frozen fish can be stored directly in the freezer, and quick freezing is recommended, but it should be noted that frozen fish is not suitable for long-term storage in the refrigerator after thawing.
