This is a common way to preserve hairy crabs. By lowering the temperature and keeping the humidity, the shelf life of hairy crabs can be extended and kept fresh. In the process of preservation, we should pay attention to the control of temperature and humidity to prevent hairy crabs from deteriorating or losing their vitality. In addition, if long-term or large-scale preservation is needed, other methods can be considered, such as using containers such as aquariums or cement pools for aquaculture preservation, or using cooling media such as ice cubes for low-temperature preservation.
