1. Refrigerator: 3-5 days. If you buy fresh live crabs and can’t finish them, you should tie the crab claws and legs with cotton rope or fine cloth strips, and then put them in the refrigerator. , you can cover the crab shell with a wet towel to maintain humidity, so that the crab can be kept fresh for 3-5 days. Do not leave it for too long, otherwise the crab will starve, lose weight or die.

2. Storage of plastic buckets at room temperature: Prepare a 30-50 cm high plastic bucket for more than 3 days, and then put the crabs into it one by one to avoid overlapping. Add an appropriate amount of water, and the water depth should be at the height of the crabs. Set it half way to facilitate the crab's breathing and store it in a cool place. It can survive for 3-5 days. If the temperature is suitable and you feed small fish and shrimps, it may live longer.
