Embodiment 1

[0014] Follow the steps below:

[0015] 1. Treatment of the gonads of pearl oysters to be extracted: the purpose is to suppress and reduce the gonads by limiting dissolved oxygen and bait, so as to facilitate the determination of the position of the pearls, preserve the pearl sacs to the maximum extent, and avoid the fullness of the gonads and pearl breeding caused by the pearl extraction operation Massive deaths of shellfish. The specific method is: (1) Put 10-20 shellfish in a conical culture cage, wrapped with 40-mesh mesh cloth, and hang them in the water layer below 2m for 10-30 days. According to the specific situation, most shellfish have no gonads or a small number of gonads as the standard. After the treatment of the gonads of the pearl oysters is completed, remove the mesh wrapped outside the culture cages, and restore the vitality for 2 to 3 days; The treated preoperative treatment buckets are suspended in the water layer below 2m for 10 to 30 days, determined acc...

Embodiment 2

[0020] Follow the steps below:

[0021] 1. Treatment of the gonads of pearl oysters: the purpose is to dispose of the gonads of the pearl oysters to be extracted by promoting the development of the gonads and inducing the discharge of sperm eggs, so as to facilitate the determination of the position of the pearls, preserve the pearl sacs to the greatest extent, and avoid the need for extraction. Massive mortality of gonad pearl oysters caused by bead surgery. The specific method is to hang the pearl oysters with full gonads in the surface seawater rich in bait for low-density culture to promote the further development of their gonads; then use the shade drying method or other methods to promote the discharge of sperm eggs. After the sperm eggs are released, the pearl oysters to be extracted go through 7 to 10 days of recuperation and recovery, and when the gonads have not yet developed or a small amount of development, live pearl extraction is carried out.

Abstract

The present invention reveals process and utensil for taking pearl from living pearl shell. The process includes sex gland treatment and activity regulation of the pearl shell before taking pearl, discharging pearl and sealing. Taking pearl with opening tool can take out pearl from living pearl shell while ensuring the vitality of the shell. The present invention makes it possible for producing several pearls repeatedly with one identical pearl shell. After taking out one pearl, one pearl core in the size similar to that of the taken pearl may be implanted for producing even large pearl, and the re-implanted pearl core is less likely repulsed and extruded resulting high core retaining rate.

Description
