2. Refrigeration room method. This kind of method is a common one. Take a plastic box, put a wet cotton towel (wet tissue paper) in it, then put Pippi shrimp in it, put a layer of wet cotton towel (wet tissue paper) on it, and then put it in the refrigerator for freezing. Be careful not to discharge the plastic box into the refrigerator immediately, the shrimp will die of cold. Be sure to put wet cotton towels (wet tissue paper) to ensure the humidity of the environment.
3. Sand cultivation method. This kind of method is rare, just like preparing a plastic box in advance, adding some handholds and ventilation holes, and then paving a layer of one to two inches of young sand. The best young sand is sea sand on the beach. This kind of natural environment is the closest to the living environment of shrimp, so it is very easy for shrimp to blend in. Generally, it can be stored for 2-3 days, and can be kept for 4-5 days or even a week in winter. However, it should be noted that the sand for shrimp cultivation should be cleaned and exposed to the sun frequently.
