Generally, the temperature of oysters is 4- 16 degrees, and the salinity is 8- 19 degrees. Salinity and temperature are different in different producing areas, so you need to consult the suppliers of producing areas for details. For example, Dalian seafood in the north and Guangdong seafood in the south, the same variety, because of different water quality, the environmental temperature is also different. Put the clean container in a small basin for a while, and don't let the sea water pass over the oysters, or don't let the sea water pass through. Cover the dry container with a clean wet cloth to keep the humidity of the oyster and the temperature of the environment. It can survive for 3-4 days.
