The water temperature should be between 20-24 degrees Celsius (68-75 degrees Fahrenheit), and the salinity between 1.020-1.025.
Meanwhile, to keep loose-leaf crabs fresh, you need to regulate the temperature of the seafood pool at 2°C-3°C and keep the temperature stable. If the temperature is low, recommended to be around ten degrees Celsius, the crabs can usually live for about one to two days. If the crabs appear to be inactive, it is recommended to eat them immediately.
It is worth noting that the survival water temperature of wild pine leaf crabs is about 6 degrees Celsius and the salinity is 23. However, artificially cultured pine leaf crabs can artificially adjust the temperature and salinity of the environment under certain circumstances so as to improve the survival rate and culturing effect of pine leaf crabs.
