Embodiment 1

[0016] The parenting method of Pinctada martensii artificially cultured by using shrimp pond water to promote ripening

[0017] (1) Preparation for maturation-promoting and cultivating pools: choose water inlet and drainage facilities with a bottom area of ​​20m 2 , A pool with a depth of 1.5m, an indoor pool with water inlet and drainage facilities, the bottom of the pool has a slope, every 3m 2 Install a loose air stone, and control the daytime light intensity of the indoor pool to 1000Lux through shading. The pool, breeding cages and aeration equipment are washed with filtered seawater before use, and disinfected with bleaching powder with an effective chlorine content of 20mg / L, and then filtered with seawater Rinse once;

[0018] (2) Selection of parent shellfish: choose 2-year-old artificially bred Pinctada martensii, with shell height greater than 6.5cm, smooth shell surface, sharp scales, intact and undamaged, gonads are developed but not plump, and males and females ...

Embodiment 2

[0022] The brooding method of Pinctada martensii grown naturally by using shrimp pond water to promote ripening

[0023] (1) Preparation for maturation-promoting and cultivating pools: choose water inlet and drainage facilities with a bottom area of ​​30m 2 , A pool with a depth of 1.5m, an indoor pool with water inlet and drainage facilities, the bottom of the pool has a slope, every 5m 2 Install a diffuser stone. The daytime light intensity of the indoor pool is controlled to 2000Lux through shading. Ponds, breeding cages and inflatable equipment are rinsed with filtered seawater before use, disinfected with 40mg / L potassium permanganate solution, and then rinsed repeatedly with filtered seawater 3 times;

[0024] (2) Selection of parent shellfish: choose 3-year-old Pinctada martensii that grows naturally, the shell height is greater than 6.5cm, the shell surface is smooth, the scales are sharp, intact and undamaged, the gonads are developed but not plump, and males and fe...

Embodiment 3

[0028] The brooding method of Pinctada martensii grown naturally by using shrimp pond water to promote ripening

[0029] (1) Preparation for maturation-promoting and cultivating pools: choose water inlet and drainage facilities with a bottom area of ​​30m 2 , A pool with a depth of 1.5m, an indoor pool with water inlet and drainage facilities, the bottom of the pool has a slope, every 5m 2 Install a diffuser stone. The daytime light intensity of the indoor pool is controlled to 2000Lux through shading. Ponds, breeding cages and inflatable equipment are rinsed with filtered seawater before use, disinfected with 20mg / L formaldehyde solution, and then rinsed twice with filtered seawater;

[0030] (2) Selection of parent shellfish: choose 2.5-year-old Pinctada martensii that grows naturally, the shell height is greater than 6.5cm, the shell surface is smooth, the scales are sharp, intact and undamaged, the gonads are developed but not plump, and males and females can be distingu...

Abstract

The invention discloses a maturation promoting culturing method of parent pteria martensii of pteria martensii. The method comprises the steps of the preparation of a maturation promoting culturing pond, the selection of the parent pteria martensii and maturation promoting culturing, the environmental condition of the pteria martensii is that maturation promoting culturing is conducted on the pteria martensii by feeding algae which grows and propagates in a prawn culturing pond, feeding and water changing are needed by prawn culturing every day, part of prawn pond water which is discharged aswasted water is used for parent pteria martensii culturing or a small amount of algae liquid is extracted to feed the parent pteria martensii, and prawn feed particles dissolved in the algae liquid are taken by the pteria martensii to further increase the nutrients of the pteria martensii to promote the development of gonad of the pteria martensii. By adopting the method to perform pteria martensii massive manual breeding, planktonic larvae have the advantages of fast growing speed, high survival rate and high metamorphosis rate, and the yield and benefit of manual breeding of the pteria martensii can be improved. The method is suitable for pteria martensii massive manual breeding and easy to popularize, and has significant social benefits and economic benefits.

Description

technical field [0001] The invention relates to a maturation-promoting cultivation method for Pinnacle martensii broodstock, which belongs to the technical field of aquaculture. Background technique [0002] Martensii pearl oyster ( Pinctada martensii ), also known as Hepu mother-of-pearl, is the main species of cultured seawater pearls in my country, and the pearls it produces are called "South Pearls". At present, the main problems in the production of "Southern Pearl" in my country are the deterioration of the breeding environment, the backward breeding technology and the degradation of the cultured species, which lead to slow growth of mother shells, poor stress resistance, small adult shells, and the inability to grow large pearls with large nuclei. And the high mortality rate of pearl oysters and poor pearl quality have seriously affected the sustainable development of the pearl industry. [0003] Pearl breeding seedlings come from artificial breeding. Nursery units a...
