Problems solved by technology

At present, the thickness of the nacre layer of seawater pearls is about 300 microns or even only about 200 microns. The wearing time of pearl jewelry is short, and even a few months will delaminate, leaving only the bead core without pearl luster, which has a very bad impact on pearl sales. As a result, the sales price of pearls is low and sales are not smooth, while the thickness of the nacre of high-quality seawater pearls should be greater than 300 microns

Embodiment 1

[0027] A method for cultivating pearl oysters of Pinctada martensii staged low specific gravity seawater cultivation, comprising the steps of:

[0028] (1) Select a breeding pond: choose a breeding pond with convenient fresh water supply, water inlet and drainage facilities, an area of ​​100 mu, and a water depth of 2 meters;

[0029] (2) Treatment of cultured ponds: 10 days before the cultivation of pearl oysters, the cultured ponds were disinfected according to conventional methods, then fertilized with water, and 8000 Penaeus vannamei seedlings with a body length of 1.2cm were put in per mu of water, totaling 800,000 tails, After the vannamei seedlings are put in, no artificial feed will be fed within 30 days, and artificial feed will be fed on the next day according to the conventional method of shrimp farming after 30 days;

[0030] (3) Cultivation of pearl oysters: Take back the oysters that have been cultured in the sea area for 7 months and are 3 months away from the h...

Embodiment 2

[0036] A method for cultivating pearl oysters of Pinctada martensii staged low specific gravity seawater cultivation, comprising the steps of:

[0037] (1) Select a breeding pond: choose a breeding pond with convenient fresh water supply, water inlet and drainage facilities, an area of ​​200 mu, and a water depth of 2.3 meters;

[0038] (2) Treatment of cultured ponds: 12 days before the cultivation of pearl oysters, the ponds were disinfected using conventional methods, and then fertilized with water. 7,000 Penaeus vannamei seedlings with a body length of 1.3cm were placed in each mu of water body, totaling 1.4 million. After the white shrimp seedlings are put in, no artificial feed will be fed within 32 days, and artificial feed will be fed on the next day according to the conventional prawn breeding method after 32 days;

[0039] (3) Cultivation of pearl oysters: Take back the oysters that have been cultured in the sea area for 8 months, and the time to harvest pearls is 3 ...

Embodiment 3

[0045] A method for cultivating pearl oysters of Pinctada martensii staged low specific gravity seawater cultivation, comprising the steps of:

[0046] (1) Select a breeding pond: choose a breeding pond with inlet and drainage facilities, convenient fresh water supply, an area of ​​300 mu, and a water depth of 2.4 meters;

[0047] (2) Treatment of cultured ponds: 13 days before pearl oyster culture, the ponds were disinfected using conventional methods, and then fertilized with water. 6,000 Penaeus vannamei seedlings with a body length of 1.4cm were placed in each mu of water, totaling 1.8 million fish. After the white prawn seedlings are put in, no artificial feed will be fed within 34 days, and artificial feed will be fed on the next day according to the conventional culture method of prawn after 34 days;

[0048] (3) Cultivation of pearl oysters: culture pearl oysters in the sea area for 7 months, and retrieve pearl oysters that are 4 months away from harvesting pearls, was...

Abstract

The invention discloses a staged low-specific-gravity mariculture method for pearl oyster cultivation of Pinctada martensii, comprising the steps of selecting a culture pond, treating the culture pond, culturing pearl oyster and harvesting pearls, and specifically including cultivating 7-8 in the sea area. Pearl oysters that are 3-4 months away from harvesting pearls are cleaned and moved to the culture pond for hanging culture. By reducing the proportion of seawater in the culture water, the low proportion of seawater is used to promote the rapid growth and reproduction of single-cell algae in the water body. The growth of mother-of-pearl provides sufficient bait supply, promotes the growth of Pinctada martensii, improves the secretion rate of pearl of Pinctada martensii to increase the thickness of nacre; The thickness of the nacre is large, which can improve the economic benefits of Pinctada martensii pearl cultivation. The staged low-specific gravity seawater culture method for Pearl oyster martensii provided by the invention is easy to popularize and apply in pearl production enterprises and farmers. It has significant social and economic benefits.

Description

technical field [0001] The invention relates to a staged low-specific-gravity seawater culture method for Pearl oyster martensii, which belongs to the technical field of aquaculture and is suitable for the production of Pearl oyster martensii pearls. Background technique [0002] Pearl oyster martensii is also called Hepu pearl oyster. The pearls produced by it account for more than 95% of the seawater pearl production in my country. The pearls cultivated by pinnacle martensii are called "South pearls". Guangdong Leizhou Peninsula is the main production area of ​​pearls in my country. At the peak of production, the pearl cultivation area reached 53,800 mu. About 45,000 people in 10 townships are engaged in the pearl industry. The annual pearl production is about 20 tons, accounting for more than 70% of the national pearl production. At present, a huge industrial chain has been formed, including pearl oyster seedling cultivation, mother oyster breeding, nucleus implantation s...
