If the temperature is not high, it can be cultured for 4 to 8 hours and cultured for 12 hours. It should be noted that if you keep razor clam at home, it is best not to spend the night, otherwise the mortality rate of razor clam is relatively high.

Preservation method of razor clam:

1, Qingshui culture. The day before buying razor clams, pick up a lot of clean water in a vat and let it stand for one night. Then the razor clam you bought is cultured in clean water that has stood for one night the next day. Put some sea salt in the water according to the ratio of 0.5%, and then change the clean water every two hours to ensure the oxygen content in the water.

2. Low temperature storage. Low temperature storage, including cold storage and frozen storage, can prolong the shelf life of razor clam, but it should be noted that blanching storage and low temperature storage are the best for the preservation time and quality of razor clam.

Extended data:

Boiling to maturity is also a fresh-keeping method, which can not only reduce the storage of some SINONOVACULA constricta, but also kill bacteria and reduce the deterioration of SINONOVACULA constricta. But the taste of razor clam will change when it is cooked, and it will not taste so good after a long time.

Fresh razor clam is not easy to preserve, but easy to deteriorate after death. You can cook the razor clam with boiling water, and then take out the meat, so that the razor clam is not easy to deteriorate and can prolong some shelf life.
