Question 1: How do mussels cultured in pots at home produce pearls? In fact, where it doesn't walk, its crawling ability is too weak. Look at this shallow ditch left behind it. You will know how hard it is to act. [] Mussels grow up day by day, and one day you will find something mysterious and noble in mussels, that is, pearls. So how do pearls grow in mussels? In ancient India, there was a saying that when an oyster opened its shell, raindrops from the sky fell into the shell and became dazzling pearls. In fact, the real cause of pearl is that other foreign bodies, such as insects and gravel, accidentally fall into the shell and destroy the epithelial cells of the shell. Then it is bred into a pearl sac, constantly secreting nacre, and then surrounding the pearl sac. As time goes on, pearls are formed. China is dotted with rivers and lakes and rich in mussel resources, which provides superior natural conditions for pearl culture. People began to use this unique way of forming pearls in mussels to cultivate pearls. However, not all mussels can be used to cultivate pearls. Most of the 140 species of mussels found in China are of low quality due to thin nacre or difficult operation, so they are of no use value. Among many mussels, the pearl produced by Hyriopsis cumingii is not only large and round, but also bright in color, which is the best variety for cultivating pearls. To cultivate pearls, a large number of Cephalotaxus fortunei are needed. The best way is to artificially breed male and female mussels. So how to distinguish the male and female mussels? Eat small fish, shrimp and algae. Artificial means putting a pearl of the right size in it, and it will secrete something to make it bigger ... let me perfect the answer. After the answer is passed, I can get three wealth values. The latest answer is: 20 12-02-0809.

Question 2: How do mussels raise pearls? Pearls are formed in shellfish, similar to shells. Whether it is natural pearls or cultured pearls, it is because shellfish accidentally come into contact with small foreign objects. When it comes into contact with its mantle, the mantle is subjected to * * *, which secretes a kind of pearlite, which wraps these tiny acrobatics layer by layer to form vegetation. After a certain period of time, pearls are formed.

Most of the substances that make up pearls and shells are calcium carbonate. Calcium carbonate forms calcite, aragonite, etc. Have different crystallization conditions. Pearls are made of aragonite, while shells are prismatic layer made of calcite. Therefore, although they are all calcium carbonate crystals, different substances-pearls and shells-are formed due to different crystal systems. If you want to keep it, put it at the bottom of the lake.

Question 3: How to implant pearl cores into mussels at home and how to raise mussels to make pearls bigger? The price of pearls is directly related to their size and luster. Looking at this sunny river, people can't help but be full of illusions. What kind of beautiful world will there be under the river? ...

Mussels are easy to raise. As long as there is clean water, the bottom of the water is usually sand. For example, the beach is a place where they can often be seen. If you want to raise pearls, it's not that easy. You need pearl mussels to raise pearls. You also need to inject pearl powder, plus rich farming experience.

Why are mussels so silent? Why don't they walk around? In fact, where it doesn't walk, its crawling ability is too weak. Look at this shallow ditch left behind it. You will know how hard it is to act. [] Mussels grow up day by day, and one day you will find something mysterious and noble in mussels, that is, pearls.

China is dotted with rivers and lakes and rich in mussel resources, which provides superior natural conditions for pearl culture. People began to use this unique way of forming pearls in mussels to cultivate pearls.

However, not all mussels can be used to cultivate pearls. Most of the 140 species of mussels found in China are of low quality due to thin nacre or difficult operation, so they are of no use value. Among many mussels, the pearl produced by Hyriopsis cumingii is not only large and round, but also bright in color, which is the best variety for cultivating pearls. To cultivate pearls, a large number of pearl mussels are needed. The best way is to artificially breed mussels, which are hermaphroditic. So how to distinguish the male and female mussels?

Expert: It's difficult to distinguish, mainly depending on the internal gills.

Reporter: Which one is suitable for parents?

Expert: Big, round and shiny.

Before hanging mussels in the pond, you can pile them up with bamboo and wood, tie them with ropes in rows, put the parent mussels in a cage and hang them in the water. In order to hang the parents at the same water level, plastic foam or coke bottles can be used as floats, which is economical and easy to use. The mussels cultivated in this way will not only lay more eggs, but also mature earlier.

When the female mussel matures, it will intermittently release a kind of protein viscose floc. What exactly is this floc? In fact, this is just a hookworm larva produced by the development of fertilized eggs in the mother clam. A female mussel can expel 654.38 00,000 ~ 20,000 hookworm larvae. Hookworm larvae are very small, so it is difficult for us to see them with our eyes. It is really difficult to collect them under natural conditions. So how can we collect hookworm larvae in large quantities? There is still a way. Sun-dried female mussels can be placed flat in a basin filled with water, and mussels will release hookworm larvae soon after encountering water. But hookworm larvae can only become young mussels if they are parasitic on fish. It seems that if you want to collect hookworm larvae. You have to put fish in the basin, and gentle yellow-throated fish should be your first choice. Of course, you should also have a strong body and complete fins. Before collection, you can pat the water so that the larvae discharged by mussels are evenly distributed in the water, and then pour the host fish, the yellow-throated fish, into the basin. 10 to 15 minutes later, see if there are any white spots on the gills of this fish. Yes At this time, the host fish can be fished out and put into the pre-prepared culture pond, and each pond is preferably 1 ~ 1.5 meters, and about 50 fish can be put in it.

After about 7 to 12 days, the parasitic hookworm larvae will develop into young mussels. Fell off the fish and sank to the bottom of the pool. After a month or so, they will grow into translucent mussels with their parents. At this time, their bodies are still very small and can only be seen with a magnifying glass. From now on, we must manage them carefully. In order to provide oxygen for these mussels in the pond, we should constantly exchange the pond water, replenish fresh water and discharge the dirty water in the pond, so as to ensure the oxygen supply and water quality in the pond. In order to prevent mussels from squeezing the bottom of the pond and affecting their growth and development, they should be turned over frequently by hand.

So, where do these little mussels get their nutrition?

Their nutrition mainly comes from these fertile pond sludge. Before putting it into the pool, it should be filtered with a sieve and made by hand ... >>

Question 4: Can ordinary mussels produce pearls? Not just any mussel.

Varieties that need to produce pearls, such as Hyriopsis cumingii.

There are many kinds of mussels, such as mussels and sea mussels. Freshwater mussels often produce pearls. Sea mussels also produce pearls. Pearls are precious medicinal materials and cheap pearls, which are produced in Lianzhou.

Question 5: How to grow pearls in mussels? There was sand in ancient times.

Question 6: How can an ordinary mussel bought from the market produce 20 cents of pearls? Hello, it won't produce pearls. If you want to raise it, it is recommended to choose pearl mussels, which have a single variety, but it is more troublesome to order pearls, and others are still very easy to raise.

Question 7: Can mussels only produce pearls 1 in the sea, and pearls can be divided into freshwater pearls and seawater pearls;

2. Mytilus is a freshwater creature, which will die if put into the sea;

3. All kinds of shellfish in nature are likely to produce pearls, but they are very rare, and the quality is even rarer, so the pearls are basically cultured now;

4, cultured pearls, generally freshwater pearls with Hyriopsis cumingii, seawater pearls with white butterfly mother-shells.

Question 8: How are pearls formed in mussels? The formation of pearl is due to the continuous accumulation of nacre secreted by some cells in the mantle of pearl oyster in connective tissue.

When small foreign objects accidentally enter the shell of shellfish, pearl oyster will feel uncomfortable. In order to eliminate the discomfort caused by this foreign body, it instinctively secretes nacre, which wraps this hateful foreign body layer by layer. After a long time, it formed a sparkling and lovely pearl. Small mussels turn pain into strength, gloriously create unparalleled jewels, and exchange their sadness for human joy.

Question 9: How do mussels produce pearls? Freshwater mussels that produce pearls are generally Hyriopsis cumingii, which is different from mussels. It is artificially implanted into the growth tissue of mussels to produce rejection and form pearls.

It is also possible for mussels to enter foreign bodies such as sand to produce natural pearls, but the probability is extremely small.
