Crabs can be frozen in the refrigerator.
Crabs are fresh aquatic products, which can be preserved for a short time after leaving water, and can be eaten in about 3 days.
Preservation is relatively simple: choose energetic crabs, tie their feet and pliers to reduce their physical exertion, and then put them in the freezer of the refrigerator and cover them with wet towels for preservation. When eating every day, choose crabs with insufficient vitality and sufficient vitality to continue preservation.

If crabs are stored improperly, deteriorate or die for a long time, people may have poisoning symptoms after eating them. Because crabs like to eat dead fish, dead shrimps and other rotten animal carcasses in water, some bacteria will appear in their bodies, especially river crabs. When crabs are alive, bacteria will be excreted with their metabolism. Once they die, the bacteria in the body will multiply, decompose crab meat and even produce toxins.
