Eriocheir sinensis is a cold-blooded animal, which hibernates on its own when the temperature is low, but if it stays in the ice for more than 48 hours, it may die due to low temperature and lack of oxygen. It is recommended not to freeze for a long time.

It is generally not recommended to freeze live crabs in the refrigerator, because the freezing temperature of the refrigerator is too low, which is not suitable for the survival of river crabs and easily leads to their death; But if it's steamed crab, you can put it in the refrigerator if you can't finish it. It can be stored in the refrigerator at low temperature for a period of time, but remember not to keep it for too long, usually 1-2 days, so as not to affect the taste of river crabs.

Suggested preservation method

If you want to keep the crabs alive for a long time, you can put them in a big basin or bathtub at home, add some water, and then feed them regularly and change the water, so that the crabs can be kept for a long time without any problems for a week.

Secondly, you can also tie up crabs, wrap them in wet towels and store them in the refrigerator. Crabs will hibernate at low temperature in the refrigerator, so they can survive for a while by reducing energy release. When eating, eat stale food first, and then eat fresh food.
