How to preserve crabs:

If the crabs you buy are tied, you need to untie the crabs before storing them and put them in the basin. Be careful not to overlap, and then add water up to the crab's mouth. If the water is too deep, the crab will suffocate due to lack of oxygen. Then put the crabs in a ventilated and cool place. The plastic basin or bucket is high enough so there is no need to cover it with a lid.
