Problems solved by technology

[0003] In order to overcome the defects of low survival rate, nuclei retention rate and excellent pearl rate of the existing mantle flake processing technology, the purpose of the present invention is to provide a method for processing mantle flakes to improve the quality of seawater pearls. It will cause additional damage to shellfish, can effectively promote the division of small pieces of mantle cells, accelerate the formation of pearl sacs, and improve the survival rate, nucleus retention rate and excellent pearl rate of pearl oysters

Embodiment 1

[0011] Select the isolated and purified chitosan oligosaccharide, and prepare a solution with a concentration of 0.5% with sterilized seawater.

[0012] Cut the outer edge of the mantle pigment-free granules with strong splitting ability from the mantle slices, soak the mantle slices for 5 minutes, or place it for about 10 minutes after applying a solution of similar concentration, and then cut into length and width. 4.5 mm mantle flakes.

[0013] The small pieces of the mantle treated with the oligochitosan solution and the bead nucleus were implanted into the pearl pouch of the pearl oyster, and after 15 days of rest, the pearl oyster implanted with the small piece of the mantle treated with the bead nucleus and the oligochitosan was transferred to seawater. Culture pearls in water bodies.

Embodiment 2

[0015] Select the isolated and purified chitosan oligosaccharide, and use sterilized seawater to prepare a solution with a concentration of 3%.

[0016] Cut out the outer edge of the mantle pigment-free granules with strong splitting ability in the mantle from the small shellfish, soak the mantle slice for 10 minutes, or leave it for about 10 minutes after applying a solution of similar concentration, and then cut into length and width. 5.5 mm mantle flakes.

[0017] The small pieces of the mantle treated with the oligochitosan solution and the bead nucleus were implanted into the pearl pouch of the pearl oyster, and after 15 days of rest, the pearl oyster implanted with the small piece of the mantle treated with the bead nucleus and the oligochitosan was transferred to seawater. Culture pearls in water bodies.

Abstract

The invention relates to a method for processing a mantle piece and for improving the quality of sea-pearl. The method is characterized as follows: chitobiose after isolation and purification is selected and is prepared into solution with the density of 0.5 to 3 percent by degerming seawater; the outer margin of non-pigment particles of the mantle which has strong fissionability is cut from the mantle piece shell, after the mantle piece is soaked for 5 to 10 minutes or placed for about 10 minutes after being applied with solution with similar density, the mantle piece is cut into a mantle piece with the length and width of both 4.5 to 5.5mm; the mantle piece which is processed by the chitobiose solution and a pearl core are put into a pearl culture bag that cultures pinctada margaritifera, and after 15 days, the pearl culturing shell which is implanted with the pearl core and the mantle piece which is processed by the chitobiose solution is transferred to mariculture water to culture pearl. The method can promote the division of the cell of the mantle piece effectively, can fasten the formation of the pearl sac and inhibit bacterial infection of operation, and the survival rate of the pear culturing shell, the core reserving rate and the excellent pearl rate can be increased by 20 percent, 15 percent and 15 percent respectively. The method has the advantages of simple implementation and obvious effect.

Description

technical field [0001] The invention relates to a method for processing mantle flakes to improve the quality of seawater pearls. Background technique [0002] Since the successful artificial breeding of Pinctada martensii in my country in 1965, seawater pearl culture has developed rapidly and has become one of the pillar industries of seawater culture in Guangdong, Guangxi and some coastal areas of Hainan. However, in recent years, the mortality rate of pearl oysters after implantation is high, the pearl collection index, the proportion of commercial pearls and high-quality pearls have dropped significantly, and the phenomenon of high rates of thin-layer pearls, dirty pearls, deformed pearls, and small pearls has become increasingly serious (Wang Aimin, Shi Yaohua , 2003). Although the research topics on the growth and body size of the pearl oyster have been paid attention by relevant departments and scholars, and many fruitful researches have been made, but in the importan...
