Xiaobian answers this question for you. Preservation method of hairy crabs:
1, keep hairy crabs in the refrigerator. As we all know, Yangcheng Lake hairy crabs are fresh aquatic products, which can be stored for a short time after leaving water. It is relatively simple to store the hairy crabs that can be eaten in about three days: choose the hairy crabs with strong vitality, tie the feet of Yangcheng Lake hairy crabs with the gate to reduce the physical consumption of hairy crabs, and then put them in the freezer of the refrigerator and cover them with wet towels for storage. 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 is to touch the eyes of hairy crabs with your hands and eat them first if they are not sensitive.
2. Plastic buckets/pots are used to store hairy crabs. Choose the vigorous Yangcheng Lake hairy crabs, and 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 Yangcheng Lake hairy crabs in it-they can't be stacked; Then add water to half the height of the hairy crabs-mainly to keep them moist, so you can't bury them all. Because you are unlikely to have oxygen-increasing equipment, if the water is too deep, the crab will die of hypoxia and suffocation. There is no need to 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 Yangcheng Lake by this method. When the temperature is not high, the hairy crabs can be preserved for more than 5 days.
3. The temporary breeding pool preserves hairy crabs. If you buy a lot of hairy crabs, you can't use the above method to store them. The best way is to let your own bathtub-a temporary breeding pool-out for Yangcheng Lake hairy crabs to enjoy: because the walls of the bathtub are smooth, hairy crabs can't escape, then gently pour Yangcheng Lake hairy crabs into the bathtub and fill them with water until they are just buried. If the hairy crabs stand up, they can breathe on the water surface. The hairy crabs stored in this way can generally last for more than 7 days or longer. The storage survival rate of good quality hairy crabs can reach more than 95%. In addition, check the hairy crabs every day and eat the hairy crabs with insufficient vitality in time.
