cold storage or frozen storage.

1. Cold storage: put the fish in a dry and sterile food storage bag, and ensure that it is completely sealed. Then put the fish in the coldest part of the refrigerator (usually the drawer at the bottom of the freezer) and set the temperature between 1 C and 4 C. Under cold storage conditions, fresh fish can generally be preserved for 1 to 2 days.

2. Frozen storage: If you plan to eat fish in a few days, you can freeze it. First, rinse the fish with clear water and dry them thoroughly; Then wrap the fish in a food preservation bag suitable for freezing, try to exclude air and seal it. Mark the date for future reference. Put the fish in the freezer or special freezer, and keep the temperature below-18 C. Under these conditions, the fish can keep fresh for 3 to 6 months.
