1, put in a plastic basin or plastic bucket:
Choose vigorous hairy crabs, prepare a plastic bucket/basin with a height of 30-50 cm, and put the hairy crabs in it without stacking; Then add water to half the height of the hairy crab's body, mainly to moisturize, and it is impossible to bury all the hairy crabs. 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.
2. Put it in a bathtub and other water tanks.
If you can't eat all the hairy crabs you bought in Yangcheng Lake for three to five days, the best way to preserve them is to let your own bathtub-a temporary breeding pool-out for the hairy crabs to enjoy: because the walls of the bathtub are smooth, the hairy crabs can't escape, then gently pour the hairy crabs into the bathtub, and fill them with water until they are just buried, so that the hairy crabs can stand on their feet and breathe on the water. According to the storage time and quantity, a small amount of small fish and shrimps are put in, and Yangcheng Lake hairy crabs are stored in this way. In addition, check the hairy crabs every day and eat the hairy crabs with insufficient vitality in time.
3. Dry release:
That is, it must be stored in a cool place without water. Otherwise, it will die of heat. It is recommended to use a basin and put the hairy crabs in the basin. You can't put water in the basin, and the top of the basin is covered with wet aquatic plants or soft vegetable leaves. This will not only ensure that the living environment of hairy crabs is not dry and wet, but also allow them to obtain sufficient oxygen.
