To embed the core (nucleus)

 To embed the core (nucleus), oysters transferred from sea water to the "operating room" pearl farm and held together on the shelf.
UBCPOKER.com Situs Judi Poker Online Terbaik Terpercaya    Pearls superior then selected and separated to open their shells slightly, then put the current nucleus seed shells / shell remains open. Then performed an incision (cut) is made in the body of the oyster, and the nucleus is inserted together with a small piece of mantle oyster others who sacrificed for this process.
    Intention of entering the mantle from another oyster to stimulate the production of nacre which is excreted by the mantle of pearl oyster host (parent).
    The oysters are then returned to the sea by assembling them on a pre-made templates and put them in a basket tied oysters from floating rafts.
    When oysters live in sea water, they will form a layer of pearl coating which fluctuates over time and is closely related to water temperature and other conditions.
    The porous layer will form conchiolin pearl shell around the nucleus and beneath the nacre. Nacre is composed of a layer of a special micro specially shaped calcium carbonate mineral called aragonite. This microscopically thin layers that make cultured pearls will feel rough when they are in friction tests on the teeth (to distinguish the original and the imitation butiara natural. Imitation pearl will be smooth like plastic, while natural pearls feels a bit rough when the bite on the tooth)
    Pearl oysters will be harvested over time depending on how much the desire of the desired diameter of the pearl. In the winter when the cold water slows down the production of nacre it will create the best color, luster, and orientation, which is the ability to reflect light pearl. Cultivation time typically ranges from one to three years, and advances in the pearl oyster growth can be monitored by x-ray .
    Pearls decision is to cut the meat carefully, so as not to die the same shells and can be cultivated again (reseed) several times to produce larger pearls as the oyster continues to grow. Pearls extracted further processed for sale. Typically, high-quality pearls sold in bulk, or auctioned regulated by green pemerintah.Kerang including mollusks that have shells symmetrical. Shell length more than twice its width, having gills are layered and have cilia. Live attached to hard objects with the help of byssus threads produced by glands foot (Asikin, 1982).

Mussels have different local names in every place, like gravestones (Jakarta), Kedaung (Bantam), and steering the ship (Riau). In Southeast Asian countries, green mussels known as snail blade (Malaysia), chaff luan (Singapore), to hong (Philippines) and O mong poo (Thailand).
Definition of a general nature and not shells have biological meaning, but its use is widespread and used in economic activity. In the broadest sense, means all the shells of mollusks with a shell. With this understanding, more appropriate to call the shellfish and clam commensurate with the meaning used in the United States. The word can also mean all the shells of shellfish that lives attached to an object. All shellfish have a pair of shell (also called grafting or valve) that mirror symmetry is usually connected with the ligaments (connective tissue). In most shells, there are two adductor muscles which regulate open-shell lid.
The scallops did not have a head (brain too) and the scallop only have eyes. Organ is owned by the kidneys, heart, mouth, and anus. Shells can move with "legs" that form a kind of flat organs removed from the shell at any time or by opening and cADRO TEXTILE Konveksi Murah Indonesia – Tlp 081362666444 !losing the shell is startling. Open circulatory system, blood vessels do not have the means. Blood oxygen supply comes from a very liquid rich in nutrients and oxygen that surrounds the organs. The food is plankton shells, by means of filtering. The mussels themselves are prey for sharks and squid. All shells are when young males. Some fem
