1, water breeding
Put the uneaten crabs into a bucket, the bucket is deeper, and the dead surface is smooth, which can prevent the crabs from climbing out. Then we pour a little water in the bucket, pay attention to the water must not put too much, never over the crab, otherwise the oxygen in the water depleted, will smother the crab. Only need to add a little water to ensure that the humidity of the crab can be. Then put some sesame seeds, crushed eggs and other food, so that the crabs can be raised for 5-10 days, and can be eaten anytime they are caught, very fresh.
2, refrigerator freezer
The legs of the crab are tied up with a rope, then put into the refrigerator freezer, and then in the crab covered with a wet towel for preservation, so you can also save the crabs for 2-3 days without dying. The purpose of tying up the legs is to reduce the physical exertion of the crabs and prolong their life; while covering the wet towel is to maintain the humidity of the crabs, which must not be less.
River Crab Purchase Precautions
How to Select CrabsCrab can be divided into two kinds: river and lake crabs and sea crabs. River and lake crabs are tender and flavorful. Fresh sea crabs have greenish gray shells, intact crabs and legs, flexible leg joints, and undamaged shell tips at both ends of the crab.
