1. Oysters can be bought and temporarily raised in professional temporary breeding ponds and put into shellfish and seafood ponds for temporary cultivation. After adjusting the appropriate salinity, temperature and oxygen, they can live for about 1-2 weeks. Generally, the temperature of oysters is 4-16 degrees, and the salinity is 8-19 degrees. The salinity and temperature of each production area are different. For specific information, you need to consult the supplier of the production area. For example, Dalian seafood in the north and Guangdong seafood in the south, the same species, have different environmental temperatures due to different water quality.
2. Place a clean container temporarily in a small water basin. Do not let the sea water cover the oysters, or put it in a dry container without sea water. Cover it with a clean wet cloth to maintain the humidity of the oysters and the temperature of the environment. , can also live for 3-4 days.
3. Refrigerated storage Oysters can be stored in the refrigerator. The refrigeration temperature is about 1-2 degrees Celsius. Bacteria will breed at high temperatures and cause rot. If the temperature is low, they will freeze. Therefore, oysters can be stored in the refrigerator for 3-5 days. or so time. The Rushan oysters purchased by the assistant lasted 14 days when kept in the refrigerator.
4. Frozen-preserved oysters can be stored directly in quick-freeze and frozen to become frozen products. They are not fresh but can still be kept fresh. Oysters themselves contain a large amount of water and carbohydrates, as well as a large number of bacteria. Therefore, after being separated from seawater, they can easily die and deteriorate. However, freezing conditions can effectively inhibit the growth of bacteria and prolong their storage. Time, so oysters can be frozen and stored. However, the longer the frozen oysters are stored, the more nutrients they will lose and their taste will deteriorate. Therefore, it is recommended that oysters should not be stored for too long, and it is best to eat them as soon as possible.
5. Store at room temperature. If oysters are soaked in water and stored directly at room temperature, they can generally be stored for about 1-2 days. If they are soaked in water and then placed in the refrigerator, they can survive at most. About a week, because the refrigerated environment can inhibit the growth of bacteria to a certain extent and is more suitable for the living environment of oysters, so the storage time will be relatively long. Do not wash the oysters with fresh water when they are dehydrated. If there is no ice in the trunk of the car, the normal time is 8 hours under constant temperature. If the temperature exceeds 30 degrees, the oysters will open in 5 hours. If they are placed in a fresh-keeping container, It can be kept for 3 to 5 days at a temperature of about minus 8 degrees. Points to note when raising oysters temporarily: 1. Never soak oysters in fresh water or seal them in airtight plastic bags, because oysters live in salt water. For oysters arriving by air, it is best to place the oysters on special dry ice in a cool place for 3 to 4 days. 2. If the purchased oysters do not need to be stored for a long time and will be eaten soon, then put a shallow layer of water, or you can directly cover the surface with a piece of wet cloth to keep the oysters moist. If you need to preserve oysters for a longer period of time, it is recommended to add more water and soak them in water, which can extend their storage time. 3. Can oysters be soaked in tap water? If the bought oysters are to be eaten immediately, you can soak them in tap water for a few hours to spit out the sediment; if they need to be stored for a few days before eating, it is recommended to store them in light salt water or sea water, suitable for salt. The temperature is 10%-25%, and the temperature is controlled at 4-6 degrees Celsius, which is more in line with its living environment and can extend its storage time. Oysters will become thinner and thinner because oysters no longer eat after being harvested. To maintain their freshness, oysters must consume their own stored energy. In other words, the longer they are on the shore, the "thinner" the oysters will be. If they are more than 1 week old, they will become thinner. thin. Therefore, oysters should not be stored for too long. The sooner you eat them, the better.
