1, keep crabs in the refrigerator. Choose vigorous crabs, bind their feet to reduce the physical consumption of crabs, then put them in the freezer of the refrigerator, keep the temperature at 5-10, and cover them with a wet towel for preservation. When eating every day, choose the ones with insufficient vitality first, and the crabs with sufficient vitality can continue to be preserved.

2, plastic wrap preservation. You can steam the crabs first, then cover them with plastic wrap, and then put them in the refrigerator for storage. When you eat them, you can take them out and eat them directly. This is also a very good method. Plastic wrap can effectively isolate the outside air and prevent crabs from oxidizing with the air. Crabs are rich in high-protein nutrients, which will have great benefits to their own health and can supplement all kinds of nutrients needed in the body in all aspects.

3. Keep it in a plastic basin. Prepare a plastic basin or plastic bucket, and put the vigorous crabs into it. Be careful not to put them in layers. Add water to half the height of the crab's body, and pay attention to moisturizing, but you can't cover them all with water, because if the water is too deep, the crabs will die of suffocation due to lack of oxygen, and the basin or bucket does not need to be covered. If the temperature is not very high, the crabs can be preserved for more than half a month by this method.
