Crabs can be kept in the refrigerator for three or four days. Generally speaking, live hairy crabs can be kept for three or four days by brushing, tying them with ropes, and then spreading wet towels on them, but after more than a week, the crabs basically die.

You can put live crabs in plastic bags without tying them tightly, so that crabs can breathe and can be kept for about eight days. Of course, this kind of food is still bought and eaten to make you taste better.

Many people know that dead crabs are not edible. Most of this food is river crabs, so once you die, you can't eat it. We must pay attention to this.

Keeping crabs cooked is also tricky. Generally speaking, you can wrap it in plastic wrap, put it in the refrigerator after cooling, and it is best to freeze it, no later than noon the next day. Be sure to return to the pot before cooking when eating, so that the taste will not be bad.
