How many years does the pearl clam have to raise pearls? Do you want to take out the pearl clam to die?

A lonely female rose curiously to the surface, enjoying the peace of the world. The wind blows, a grain of sand flies into the shell opened shell body, in the soft flesh and sand, shell constantly secretes liquid, wrapped in sand, in order to heal the great pain-pearl, so formed.

Pearl is produced in pearl shellfish, mussels and other mollusks, produced by endocrine action containing organic matter mineral (aragonite) pellets. When the small foreign matter from the outside enters the pearl mussel body and contacts the mantle membrane of the mussel, the mantle membrane is stimulated and secretes nacre, which wraps the foreign matter layer by layer, thus forming pearls.

Pearl culture technology is based on the above principles, with artificial methods, divided into nuclear pearls and seedless pearls.

Nucleated pearl: living epithelial cell pieces (referred to as cell pieces) cut from the mantle of the pearl oyster are implanted into the connective tissue of the mantle of the oyster together with the artificial nucleus prepared from the clam shell. The implanted cell pieces rapidly proliferate around the artificial nucleus by relying on the nutrients provided by the connective tissue, forming pearl sacs and secreting nacre, thus generating artificial nucleated pearls.

Nuclear-free pearl: it is a pearl produced by implanting only small pieces of cells into the mantle membrane, forming pearl sacs through cell proliferation, and secreting nacre into the sacs. Freshwater cultured pearls, mostly seedless pearls.

Will the clam die if I take the pearl out? The clam was cut open with a knife when it was taken, that is to say, it was already dead when it was taken, because otherwise it would be very inconvenient to take the pearl. And the pearls are in the clam meat, and taking the pearls will bring the clam meat out by the way. After the pearl was taken, the clam was completely dead.
