Embodiment Construction

[0008] The present invention prepares and selects artificially cultivated mussels whose age is not more than 1 full age, whose shell length is 7cm to 9cm, and whose individual weight is not less than 20g, as the working mussel before the planting of the pearl sac stage; Thick, bright-coloured shell, bright, dark green to blue or yellowish-brown, rapid growth in each growing season, growth lines 2cm to 3cm apart, intact body without damage, neat belly margin, obvious yellowish-brown The shell cortex and mantle are thick, tender and white, not detached from the shell, the intestines are full of food, the legs are fat, the body is strong, the two shells close quickly after being frightened, and the water spray is powerful. When selecting, it is necessary to inspect the mussels one by one, and remove the injured or diseased mussels; when the working mussels are temporarily kept at a water temperature of about 20°C, the mussels for self-propagation and self-use are temporarily kept ...

Abstract

The invention provides a method for nurturing large-sized high quality nucleated pearls, relating to a producing method for nurturing large-sized nucleated pearls, the problems of high mortality of freshwater nucleated pearl pearly mussel, high nuclear spitting rate and bad smooth finish need to be solved. The technology programmes of the invention includes two processes: pearly mussel pearl sac nurturing and nucleated pearl nurturing, which are characterized in that: during the process of pearly mussel pearl sac nurturing, enlarge the small inserted slices into squares of 8mm-10mm, each of the left and right mussel has two squares, the squares are placed in the thickest areas at the middle and back part of the mantle membrane central membrane, after the pearly mussel are nurtured for 2-3 years, fetch the pearls without nuclei in the pearly mussel, insert pearl nuclei of 9-15mm and hanging nurture them in pearl nurturing water area. The invention is suitable for nurturing large sized nucleated pearls.

Description

Technical field: [0001] The invention relates to a production method for cultivating large-scale nucleated pearls. Background technique [0002] In the 4th issue of "Inland Aquatic Products" in 2004, the article "Freshwater Nucleated Pearl Insertion Method" (Hubei Provincial Fisheries Research Institute) introduced that when people explored the formation mechanism of pearls, they found that the core of pearls was foreign matter such as sand grains. Therefore, there is a saying that "foreign matter stimulates pearl formation". Around the 13th century, it was discovered that the mantle of shellfish secreted pearls. Therefore, people used the mechanism of shellfish mantle to secrete pearls and used surgical methods to imitate natural foreign body stimulation to cultivate nucleated pearls. The operation method that utilizes the mechanism of shellfish mantle to secrete pearls combined with foreign matter stimulation has become the traditional production method of nucleated pearl...
