1. If the refrigerator has a better cooling effect, the crabs will usually keep longer, possibly up to about 3 months. If the refrigerator's cooling effect is poor, the preservation time may be shorter, about 2 months. In addition, if it is in hot summer, due to the high indoor temperature, the preservation time of crabs may be relatively shorter, about 2 months. And in cold winter, when the indoor temperature is low, the preservation time of crabs may be relatively longer, possibly up to about 3 months.
2. If it is in a refrigerator freezing environment below 0°C and sealed relatively well, the shelf life of crabs can reach about 3 months. Because the low temperature environment can effectively inhibit the growth of bacteria, mold and other microorganisms, thus extending the shelf life of crabs.
3. There is a view that crabs can be preserved for 3 to 6 months if stored in the frozen layer of the freezer, and may even be preserved for up to 1 year without spoilage. However, this kind of prolonged preservation may not be recommended because prolonged freezing may affect the taste and nutritional value of the crabs.
4. For the frozen preservation of live crabs, one method is to neatly arrange the bundled fresh crabs into a foam box, add water until it does not cover the surface of the crabs, and then put them into the freezer to set the lowest temperature to freeze as soon as possible. This method can preserve them for up to one month. However, it is important to note that when freezing, you must ensure that the crabs are completely fresh, half dead or not the spirit of the crabs are not suitable for freezing and preservation.
