Why does the United States recycle a large number of discarded oyster shells? This oyster shell is the oyster shell of us southerners and the oyster seed of northerners. In summer, the only thing that can compete with crayfish is fresh and juicy oysters. Because of its excellent taste and physical fitness, it has been deeply loved by everyone for many years. Every time we eat oysters, the thick shells are thrown aside. For us in China, the meaning of his life ends here. The United States is different. They even pay more attention to this oyster. They can recycle a lot, clean them, put them in a special container and throw them back into the sea. What happened?
What's the use of these worthless shells? Don't worry, there are millions of oyster seedlings thrown into the sea with oyster shells. These little oysters are still very young and have no good ability to protect themselves in the face of strong winds and waves. They can only parasitize on other objects, and the recycled oyster shells thrown together are the best materials. Although it is the birth number of the haunted house, the babies feel the taste of home in it, and also give the fragile oyster seedlings a place to live. When these little oysters grow up, the old oysters will become oyster education, thus restoring the previously destroyed marine ecology, that is, using the waste oyster shell as the soil that oyster shell seedlings are taken out of the sea and used in the sea.
Then why can oysters raise oyster seedlings? You may know that although oysters look as hard as stones, they actually contain a lot of calcium and zinc, of which zinc is the highest. Besides red meat, they are the foods with the highest zinc content. However, we humans can't chew raw oyster shells, but oyster seedlings can. Oyster seedlings will be tightly attached to the oyster shell, and they will begin to exchange substances, so that the seedlings can thrive. Moreover, the small oysters that have a home can safely eat algae food in the sea, thus growing steadily until the day when they are salvaged by humans. Using discarded oyster shells as Petri dishes can improve the survival rate of oysters without affecting the marine environment. It can even absorb too much algae and purify water, which can be said to be beneficial and harmless. No wonder the United States can become the world's number one masterbatch producer. In that case, oyster shells play such an important role. Why doesn't China recycle oysters? In fact, oyster farming in China ranks third in the world, which is also a very good result.
How to deal with the problem of oyster recycling in China? China also has its own oyster culture method, which is also to cultivate oyster seedlings. We usually use a rope, tires and other existing materials to make oyster seedlings adsorbed on it, which can not only improve the survival rate of oysters, but also better manage and package them. When the oyster grows up, you just need to pull the rope at the other end. Oysters are like a string of beads, and you don't need to spend extra money to recover oyster shells when you salvage them. Save time, save time, save money, why not? Oysters are not useless in our country. As a traditional Chinese medicine, oyster shell has been recorded for a long time, which can be used as medicine and can also be a magic weapon for many fish lovers. Putting the washed oyster shells in a fish tank can be used as decorations, and can also be used to adsorb algae to purify water. In recent two years, Shao 'an, the hometown of oysters in China, began to recycle a large number of oyster shells and make them into soil conditioners in the biological park, which solved the pollution problem of oyster shells, realized the secondary utilization of discarded oyster shells, and brought extra income to local residents, and changed from a poor village to a rich village.
Looks like oysters are really a good thing, don't you think?
