If it is a live crab, it is best to raise it with a bucket. If it is raised at home, it can live for about three days.Put the crab in a bucket, add water properly, but don't cover it, so that it can't climb out, and it won't affect breathing.If you want to keep it longer, you need to put it in the refrigerator to freeze it, it is best to freeze the live crab directly, and then freeze it will affect the taste.
1. Water level: If you want to keep crabs, you need a certain amount of water first. This animal itself lives in water, and it can easily die of dehydration.It should be noted that it can not be raised in too deep water, it is best not to water level over it, so that it can breathe from the air, can let it live longer.
2. Oxygen: Crabs have a relatively high demand for oxygen. It is relatively easy to raise them at a low water level. If the water level is relatively high, the crabs will be completely immersed in the water. This requires that the water body be oxygenated at all times to ensure that the oxygen in the water is sufficient, so as not to cause the crabs to die of anoxia.
3. Temperature: Crabs are not resistant to high and low temperatures, so if you want to keep them alive, you must take good measures to keep them warm.Usually the temperature should be controlled between 15-25 C, below 15 C will affect its feeding, and may even freeze to death, too high is not conducive to its survival.
