Embodiment 1

[0014] The production method of the pearl oyster new line that improves pearl nucleus quality comprises the steps:

[0015] (1) Selection of parents: Select the clam-backed mussel with large individual, intact and undamaged shell, smooth shell surface color, wide trailing edge, fat and non-sick soft body, no damage to gill flap, and strong physique as the female parent. Sailing mussels are used as the male parent, and the male and female parents are suspended separately for 6 months before the hybridization;

[0016] (2) Treatment of the parents: Put the parents of the Limbusculus selected in the step (1) into the breeding pool of the parents of the Limbusa, and feed them with 60% of diatoms, 20% of eel bone meal, 10% of soft-shelled turtle eggs, The bait mixed with 5% vitamin B and 5% coconut milk, the daily dosage is 20kg / thousand mussels, and the water temperature in the breeding pool is controlled at 14°C; Feed yeast and an appropriate amount of organic fertilizer. The am...

Embodiment 2

[0020] The production method of the pearl oyster new line that improves pearl nucleus quality comprises the steps:

[0021] (1) Selection of parents: Select the clam-backed mussel with large individual, intact and undamaged shell, smooth shell surface color, wide trailing edge, fat and non-sick soft body, no damage to gill flap, and strong physique as the female parent. The sail clam is used as the male parent, and the male and female parents are separated and raised 12 months before the hybridization;

[0022] (2) Treatment of the parents: Put the parents of the Limbusculus selected in the step (1) into the breeding pond of the parents of the Limbusa, and feed them with 45% of diatoms, 30% of eel bone meal, 10% of soft-shelled turtle eggs, The bait formulated with 5% of group B vitamins and 10% of coconut milk, the daily dosage is 10kg / thousand mussels, and the water temperature in the cultivation pool is controlled at 12°C; Feed yeast and an appropriate amount of organic fe...

Abstract

The invention discloses a production method of a new strain of a pearl mussel for improving pearl nucleus quality. The method comprises the steps of parent selection, parent processing, artificial insemination and hatch. According to the method, difficult problems of hybridization aspects of lamprotula leai and hyriopsis cumingii are solved; through cultural experiments, a hybridization F1 generation is characterized in that the hybridization F1 generation has the characteristics such as thick shell and bright, clean and compact shell quality, the yield and quality of a pearl nucleus are improved, and the pearl nucleus can be widely applied to large scale production of freshwater pearl and shellfish industry and has better production and application values.

Description

technical field [0001] The invention relates to the technical field of breeding of new strains of freshwater pearl mussels, in particular to a production method of new strains of pearl mussels that improves the quality of pearl nuclei. Background technique [0002] Pearl cores are round particles made of shells or other substances that are implanted in the mantle of mother-of-pearl when artificially cultivating nucleated pearls. Among them, the pearl cores used for artificially cultivated pearls from seawater pearls are mostly freshwater nodules. Made from mussels and other shells. The number of bead cores that can be inserted into a female oyster should be determined by the size of the surgical shell and the diameter of the bead core. The larger the bead core diameter, the fewer the number of bead cores inserted, and the smaller the bead core diameter, the more the number of inserted bead cores. [0003] The clam with back tumor, also known as the hemp skin clam, has a ver...
