1. Fresh fish can be frozen and stored after being processed.

2. Fish can be placed in the refrigerator after being killed. But it depends on whether it is placed in the refrigerator or freezer. If you kill the fish and eat it within two days, it is recommended to put it in the refrigerator compartment to ensure the freshness of the fish as much as possible. But if you kill the fish, it may take a week or a month before you eat it. In this case, you need to store it in the freezer.

However, keeping fish in the freezer for a long time will cause the fish meat to become rough and lose a lot of nutrients. Therefore, after killing the fish, it is best to eat it on the same day to ensure the best nutrition and taste.
