Hairy crabs are fresh aquatic products, which can be kept for a short time after leaving water. The quantity of hairy crabs purchased can be eaten in about 3 days. It is relatively simple to keep them: choose hairy crabs with strong vitality, tie their feet and gates to reduce their physical consumption, and then put them in the freezer of the refrigerator and cover them with wet towels. When eating every day, choose the ones with insufficient vitality first, and the hairy crabs with sufficient vitality can continue to be preserved. The way to distinguish the vitality of crabs is to touch the eyes of hairy crabs with your hands and eat them first if they are not sensitive.
Method 2: Keep hairy crabs in plastic buckets/pots (storage time: about 7 days).
Prepare a plastic bucket/basin with a height of 30-50 cm. The inner wall of the plastic bucket/basin is smooth and difficult to escape. Put the hairy crabs in it, don't stack them; Then add water to half the height of the hairy crab body to keep it moist. Don't bury all the hairy crabs. If the water is too deep, the crabs will die of suffocation due to lack of oxygen. Don't cover the bucket/basin, check the hairy crabs every day, eat the hairy crabs with insufficient vitality in time, and preserve the hairy crabs in this way. When the temperature is not high, the hairy crabs can be preserved for more than 5 days.
