Golden pearl is a kind of mariculture pearl, which is produced in white-lipped shellfish or golden-lipped shellfish. Its origin is mainly distributed in Southeast Asia, with low output and high price. Sulu Sea, located near Palawan, a southwestern province of the Philippines, breeds dazzling golden pearls with its unique natural conditions. Golden pearl is a kind of mariculture pearl.
Raising pearls is also raising mussels. The physical condition of mussels affects the "pearl baby" in the body all the time.
? After the mussel was born, it stayed in an incubator for two months, and then it was put into a special cage and put into a specific sea area to "go deep into life". The cage is suspended below the water10m to18m, and the water temperature must be kept between 28 and 30 degrees Celsius. About 14 months later, these mussels finally "came of age" and began to undertake the mission of breeding pearls.
? Fish farmers put the washed mussels into a pool prepared in advance, let the mussels "open their mouths" voluntarily by adjusting the water temperature, and then implant carefully selected pearl cores into the mother mussels. In the next four months, farmers will help mother-of-pearl turn over every day to ensure that pearls are evenly distributed, otherwise, due to gravity, pearls are likely to grow into water droplets.
Four months later, the breeder will also make a "comprehensive physical examination" of mother-of-pearl and pearls with X-rays. In addition to checking whether the mother shell is healthy, it is more important to see whether the pearl is still in the mother berry. In the final harvest stage, the breeder carefully took the pearl out of the shell with special metal tweezers, without hurting the mother shell at all.
? Of all the successfully hatched mussels, only 12% can live to the stage of nuclear implantation, and only 10% can finally produce pearls. High-quality pearls are rare. Branellec said that he has handled more than 20 million pearls since the establishment of the farm, but only two or three pearls are really perfect.
