#Fukui Nucleus Plant: Pearl nuclei are mainly used in seawater pearl farming and implanted into oysters to form the basis for the attachment of mother-of-pearl. Shells and pearls have the same composition and similar structure, so they are less likely to be rejected by pearl oysters. .....
Mabe pearls are a general term for half pearls that grow close to the shell. For foreigners, the Buddha pearls with a long history in China are also a type of Mabe pearl. Mabe pearls are generally cultivated with freshwater pearl oysters, which are less exclusive and have a lower risk of death......
In addition to the four main types of cultured pearls, there are Keshi pearls and Mabe pearls produced during pearl culture. Keshi pearls are small, non-nucleus pearls that are an unexpected byproduct of pearl culture. The original meaning of "Keshi" in Japanese is "poppy" (ケシ, mustard), which is used in Japanese to refer to all pearls without nuclei. However, the jewelry industry generally believes that only non-nucleus cultured pearls found during the cultivation of seawater pearl oysters are considered Keshi pearls......
Seawater pearls are mainly divided into South Sea white pearls, South Sea gold pearls, Tahitian black pearls and Japanese seawater cultured pearls (also called AKOYA pearls). Except for the latter, the first three types of seawater pearls are larger in size, generally ranging from 9 mm to 18 mm, and even rare treasures exceeding 20 mm have been found...
Coastal cities are developing rapidly. Wastewater discharge and feed put by fish farmers in the past are not all absorbed by fish. The remaining feed and fish excrement are accumulated in the breeding areas, which leads to a vicious cycle and causes overnutrition, which often triggers red tides. Once the red tide comes...
