Embodiment 1

[0042] The industrialized environment of the present embodiment: the pH value of the cultured water body is 7.5-8.5, the water temperature is maintained at 15-28° C., the dissolved oxygen in the water is sufficient, the cultured water body is located in the culture room 1, and the culture room 1 is provided with several layered stacked Culture pool unit 3, culture basket 4 is suspended in the culture pool unit, and each culture pool unit 3 is connected to the reservoir 2 through pipelines, and each culture pool unit is connected to the reservoir 2 through the water supply pipeline 5 and the return pipeline 6 respectively. Summarize and connect, place an ultrasonic generator 15 in the cultured water body, and perform periodic ultrasonic stimulation on the pearl mussel 45-50 days after the pearl mussel is implanted into the nucleus, the ultrasonic frequency is 21000-35000 Hz, and each ultrasonic stimulation time is 3-10s.

[0043] In this embodiment, ultrasonic stimulation is car...

Embodiment 2-5

[0071] Example 2-5 ： The difference between these three embodiments and embodiment 1 is that: periodic stimulation is performed with different ultrasonic frequencies and ultrasonic intensities as shown in Table 1.

[0072] Ultrasonic frequency and intensity of table 1 embodiment 2-5

[0073]

[0074] Comparative experiments: 5 comparative experiments corresponding to the above Examples 1-5 were carried out. The difference between the comparative experiment and Examples 1-5 lies in the lack of the ultrasonic stimulation process of the present invention, while other contents are the same. The whole pearl culture experiment was carried out synchronously with the above embodiment 15, and had the same culture time.

[0075] By comparing Examples 1-5 with the corresponding comparative experiments, the results show that: after 12 months from the first phase of ultrasonic stimulation, the method of the present invention can make the bead layer thicken by an average of 1 mm; fr...

Embodiment 6-11

[0076] Example 6-11 ： The breeding environment in Examples 6-11: the breeding water body is located in the breeding room, and the breeding room is provided with a number of layered and superimposed culture pond units, and the culture baskets are suspended in the culture pond units, and each culture pond unit is connected to the reservoir through pipelines , each culture pool unit is connected to the reservoir through the water supply pipeline and the return water pipeline respectively, and an ultrasonic generator is placed in the culture water body, and the pearl mussel is periodically ultrasonically stimulated 45-50 days after the pearl mussel is implanted into the nucleus, The stimulation time is 10s.

[0077] Ultrasonic stimulation is carried out in three phases, with 4 months as a phase, and the frequency of ultrasonic stimulation in each phase is as follows:

[0078] The first phase of ultrasonic stimulation:

[0079] The first month: Stimulate once every 28 hours; ...

Abstract

The invention provides an ultrasonic stimulation method for promoting secretion of pearl oysters. According to the method, the pH value of aquaculture water ranges from 7.5 to 8.5, the water temperature is kept in a range from 15 DEG C to 28 DEG C, dissolved oxygen in water is sufficient, the aquaculture water is located in an aquaculture chamber, a plurality of aquaculture pond units which are layered and stacked are arranged in the aquaculture chamber, aquaculture baskets are suspended in the aquaculture units which are converged and connected with a water storage pool through a water supply pipeline and a water return pipeline respectively; and an ultrasonic generator is arranged in the aquaculture water, periodical ultrasonic simulation is performed on the pearl oysters after nucleuses are implanted in the pearl oysters for 45-50 days, the ultrasonic frequency is in a range from 21,000 Hz to 35,000 Hz, and each ultrasonic stimulation time is 3-10 s. The ultrasonic stimulation method for promoting secretion of the pearl oysters has the benefits as follows: through ultrasonic stimulation for promoting secretion of the pearl oysters, pearl sacs can uniformly perform secretion, the growth period is shortened, and the pearl quality is improved; the operation is safe and convenient; the water environment is adjusted automatically, and time and labor are saved; and factory-like indoor aquaculture is adopted, the land is saved, and the intensive effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of pearl cultivation methods, and in particular relates to an external physical stimulation method for promoting the secretion of pearl mussel nacre, increasing the perfect circle ratio of pearls, shortening the growth cycle, increasing the diameter of pearls, and improving the color of pearls. . Background technique [0002] At present, there are problems such as thin pearl layer and uneven color in pearl products, which lead to the low quality of pearl ornaments. The reasons for the above phenomenon on the one hand are: the pollution of the breeding waters and the environment, the backward breeding technology, the lack of pollution prevention and control technology, etc.; Even excessive occupation of increasingly scarce farmland resources. In recent years, many places have proposed to reduce the area of ​​pearl cultivation, and have established specific procedures for fading out of this production field ...
