Embodiment 1

[0032] A method for culturing and cultivating pearls of sea pearl oysters of the present invention comprises the following steps:

[0033] (1) Intensive cultivation of small scallops: 17 days before the nucleation operation, select Pinctada martensii with an age of 12 months as the small scallops, and move the scallops to a pool with shading and rain-proof facilities for hanging at a breeding density of 130 animals. / m 3 ; Feed Chaetoceros muernii, Chaetoceros calcareus, Pavlova viridis, and Flat algae subcardioides at a ratio of 2:2:1:1, twice a day, with a feed concentration of 27,000 cells / mL · Every other day, vitamin B complex 0.2mg / L was fed; microwave aeration was maintained, and the water was changed every 3 days, with a water change of 25%.

[0034] After the intensive cultivation of the small pieces of shellfish is completed, the mantles of the small pieces of shellfish are obtained and small pieces of cells are made.

[0035] (2) Nucleation operation: Select the 2...

Embodiment 2

[0039] A method for culturing and cultivating pearls of sea pearl oysters of the present invention comprises the following steps:

[0040] (1) Intensive cultivation of small scallops: 18 days before the nucleation operation, select 16-month-old Pinctada martensii small scallops and move them to a pool with light- and rain-proof facilities for hanging at a breeding density of 125 / m2 3 ; Feed Chaetoceros muernii, Chaetoceros calcareus, Pavlova viridis, and Flat algae subcordiformis at a ratio of 2:2:1:1, twice a day, with a feed concentration of 25,000 cells / mL · Every other day, feed vitamin B complex 0.1mg / L; keep microwave aeration, change the water every 3 days, and change the amount of water by 30%.

[0041] (2) Nucleation surgery: Select the 24-month-old Pinctada martensii as the nuclei, and use the method of sending the nucleus first and then the slices to carry out nucleation. Insert a bead nucleus, paste the transplanted cell pieces on the left side of the bead nucleus...

Embodiment 3

[0045] A method for culturing pearls of sea pearl oysters, comprising the following steps:

[0046] (1) Intensive cultivation of small scallops: 15 days before the nucleation surgery, select 12-month-old pearl oysters (commonly known as black butterfly scallops) and move them to a pool with shading and rain-proof facilities. The breeding density is 110 / / m 3 ; Feed Chaetoceros muernii, Chaetoceros calcareus, Pavlova viridis, and Flat algae subcordiformis at a ratio of 2:2:1:1, twice a day, with a concentration of 32,000 cells / mL· The next day, 0.2 mg / L of vitamin B complex was fed; microwave aeration was maintained, and the water was changed every 3 days, with a water change of 40%.

[0047] (2) Nucleation operation: select the 24-month-old pearl oyster as the nuclei, and use the method of sending the nucleus first and then the slices for nucleation, and implant one in the left and right pockets of the oyster. For the bead nucleus, paste the transplanted cell small pieces on...

Abstract

The invention discloses a seawater pearl shell culture method, and belongs to the technical field of pearl culture. The method comprises the basic steps of intensified cultivation of small shellfish, nucleus implantation operation and segmented cultivation in a harbor and an open sea deepwater area according to the water temperature. In the pearl culture process of seawater pearl shells, by enhancing the nutrient level of cell small piece shells, the transplanted cell small pieces are promoted to proliferate to form pearl sacs, and the cell biomineralization capacity of the pearl sacs is improved; patches are attached to the left side of the left bag pearl nucleus and the right side of the right bag pearl nucleus, so that transplanted cell patches are tightly attached to the surfaces of the pearl nucleuses, and the pearl forming rate is increased; in the high-temperature period, the pearl breeding shellfish is bred in an open sea deep water area, and the pearl breeding shellfish is moved back to the bay to be bred after passing through the high-temperature period, so that the survival rate of the pearl breeding shellfish is increased; the pearl breeding shellfish for seawater pearl production is high in survival rate, the pearl quality is good, the economic benefit of pearl breeding can be improved, and the method is suitable for seawater pearl production.

Description

technical field [0001] The invention belongs to the technical field of pearl culturing, and in particular relates to a method for culturing pearls in seawater pearl oysters, which is suitable for the production of artificially cultured pearls from Pinctada martensii, Pinctada mollusks and Pinctada maxima. Background technique [0002] Seawater pearls cultivated in the coastal areas of Beibu Gulf of my country are called "South Pearls" and have important economic value. Seawater pearl oysters that breed pearls include Pinctada martensii ( Pinctada fucata martensii , also known as Hepu mother-of-pearl), large mother-of-pearl ( Pinctada maxima , commonly known as white butterfly shells) and mother-of-pearl ( Pinctada margaritifera , commonly known as black butterfly shell), among them, pearls cultivated by Pinctada martensii account for more than 95% of my country's seawater pearl production. Zhanjiang City is the main producing area of ​​South Pearl, and its pearl output ...
