1, use the refrigerator to refrigerate.
For the preservation method of live crabs, we must pay attention to two points. The first is to keep them alive, and the second is to keep them fat, so we must keep them in a low temperature when using the refrigerator. This is to keep them in a dormant state. Static is to make them not consume too much energy, but to completely put them in a dormant state. The way to do this is to reduce their metabolic consumption. The crabs we bought can be tied up with straw ropes and put into the refrigerator, covered with a wet cloth, and the temperature will reach.
2. Feed crabs at room temperature
Be sure to put the purchased crabs into a plastic bucket with a height of 50cm. Be careful not to stack them. Just add the water to about half. If it is completely submerged, it may cause too much pressure and make it impossible to move. This plastic bucket does not need to be covered. Just change the water every day.
Precautions for storage of hairy crabs
If the hairy crabs are stored in a basin by spraying water, the storage time is generally 2-3 days. If hairy crabs are stored in barrels, the storage time is usually 3-5 days. If hairy crabs are stored in a bathtub, the general storage time is 5-7 days.
It is necessary to pay attention to the survival of hairy crabs during storage. It is inflexible to touch the eyes of hairy crabs with your hands and eat them as soon as possible, so as not to affect other surviving hairy crabs, and the storage time will be shortened.
