Embodiment 1

[0026] A method for cultivating black pearls by autologous transplantation of nacres provided by the invention comprises the following steps:

[0027] (1) Selection of mother-of-pearl oysters: choose the mother-of-pearl with a shell age of 24 months, a shell height of 11cm, a bright peacock green pearl layer on the inner surface of the shell, a strong luster of the nacre layer, and no perforation and no delamination on the shell surface as the planting nucleus. mother-of-pearl;

[0028] (2) Anesthesia of Pinctada japonica: before the nucleation operation, anesthetize Pinnacle oyster according to conventional methods;

[0029] (3) Nucleation operation: plug the mouth of the anesthetized n. nacre, and then cut a small piece of mantle with a length of 2.5 mm and a width of 2.5 mm from the abdomen of n. n. After closely adhering to the bead nucleus, it was implanted into the connective tissue of the broccoli oyster that had been cut into small pieces. One bead nucleus was implant...

Embodiment 2

[0033] A method for cultivating black pearls by autologous transplantation of nacres provided by the invention comprises the following steps:

[0034] (1) Selection of mother-of-pearl oysters: choose the mother-of-pearl oyster with a shell age of 26 months, a shell height of 13cm, a bright reddish nacre on the inner surface of the shell, a strong luster of the nacre layer, and no perforation and no delamination on the shell surface as the planting nucleus. mother-of-pearl;

[0035] (2) Anesthesia of Pinctada japonica: before the nucleation operation, anesthetize Pinnacle oyster according to conventional methods;

[0036] (3) Nucleation surgery: plug the mouth of the anesthetized n. nacre, and cut a piece of mantle with a length of 2.7 mm and a width of 2.7 mm from the abdomen of n. n. Nuclei were implanted into the connective tissue of Pinctada japonica that had been cut into small pieces, and one bead nucleus was implanted in each shell. The location of the nucleus was the l...

Embodiment 3

[0040] A method for cultivating black pearls by autologous transplantation of nacres provided by the invention comprises the following steps:

[0041] (1) Selection of mother-of-pearl oysters: Choose the mother-of-pearl oyster with a shell age of 30 months, a shell height of 14cm, a bright green nacre on the inner surface of the shell, a strong luster of the nacre layer, and no perforation and no delamination on the shell surface. mother-of-pearl;

[0042] (2) Anesthesia of Pinctada japonica: before the nucleation operation, anesthetize Pinnacle oyster according to conventional methods;

[0043] (3) Nucleation operation: plug the mouth of the anesthetized n. nacre, and cut a small piece of mantle with a length of 3 mm and a width of 3 mm on the abdomen of n. n. After sticking closely, they were implanted into the connective tissue of n. nuclidea that had been cut into small pieces. One bead nucleus was implanted in each bead. The location of the nucleus was the left pocket, a...

Abstract

The invention discloses a method for cultivating black pearls by autotransplantation of pinctada palustris, which comprises the following steps: selecting pinctada palustris, performing anesthesia treatment on the pinctada palustris before an operation, performing a nucleus implantation operation, recuperating the pinctada palustris, cultivating and managing the pinctada palustris and the like, and comprises the following steps: selecting healthy pinctada palustris with a pearl layer with strong luster on the inner surface of the pinctada palustris as the nucleus implantation pinctada palustris; the method comprises the following steps of: anesthetizing the pearl shells before a nucleus implanting operation, taking down a mantle small piece by using a special tool, implanting the taken-down mantle small piece and pearl nucleuses into connective tissues of the pearl shells with the small pieces taken, and then recuperating the pearl shells after the operation in a fish pond and cultivating the pearl shells in a pearl breeding sea area in sequence. By adopting the method to cultivate black pearls through nucleus implantation of the pinctada shells, the survival rate of the pinctada shells is high, the nucleus-remaining pearl-forming rate is high, the nacre secretion speed is high, the pearl luster is strong, the method is suitable for artificial pearl cultivation production of the pinctada shells, the method is easy to popularize and apply in pearl production enterprises and farmers, and the social benefit and the economic benefit are good.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating black pearls by autologous transplantation of nacre. Background technique [0002] Pinctada margaritifera, also known as black butterfly oyster, belongs to the pearl oyster family and the genus Pearl oyster, and is the only pearl oyster that can cultivate black pearls. Mother-of-pearl is the pearl shell with the largest variety of shell nacre colors. The colors of the nacre in the shell are white, gray, green, red, peacock green, peacock blue, dark black, and various color combinations such as gray-black, yellow-green, The colors of the black pearls cultivated are silver gray, gray-black, gray-white, yellow-brown, purple-red, light red, purple, green, peacock green, peacock blue, dark black, etc. Value black pearls are intensely lustrous reds, peacock greens, peacock blues, greens and deep blacks. French Polynesia in the South Pacific is...
