Problems solved by technology

[0007] In view of the problems existing in the prior art, the purpose of the present invention is to provide an artificial seedling raising method based on freshwater pearl cultivation, which can provide an attachment point for the seedlings by setting the seedling raising device, so that the seedlings are not easy to be separated from the seedling pond under the fluidity of water. The bottom mud is mixed together, so that it is not easy to be killed by hypoxia or insufficient nutrients due to being covered by the bottom mud and affect its growth process. With a large number of seedlings, the growth of the seedlings is not easily affected by each other, so that it is not easy to inhibit the growth of the seedlings, so that the seedlings can absorb sufficient nutrients during the growth and development of the seedlings, accelerate the growth rate of the seedlings, and improve the survival rate of the seedlings

Embodiment 1

[0048] see figure 1 , the method for artificial seedling cultivation based on freshwater pearl cultivation, comprising the following steps:

[0049] Step 1: Selection of parent shellfish. The age of collecting clams is 3-5 years, the body length is greater than 12cm, the shells are intact and not damaged, the shells are strong and plump, and there is no infection by diseases and insect pests. natural fertilization;

[0050] Step 2: Collect the sperm and ovum liquid obtained from fertilization in Step 1, put them into a container, and stir slowly to obtain a uniformly mixed liquid;

[0051] Step 3: After 6-8 hours of fertilization, that is, after the mixed solution in step 2 is left to stand for 6-8 hours, the larvae gradually develop and form, and appear as white strips;

[0052] Step 4: When the larvae develop to the straight-line hinged larval stage, that is, the D-type worm stage, count the amount of larvae and transfer them to the seedling device at a density of 3-4 / ml i...

Abstract

The invention discloses an artificial seeding raising method based on fresh water pearl culture, and belongs to the technical field of pearl culture. According to the artificial seeding raising method based on fresh water pearl culture, a seedling raising device is arranged to provide an attachment point for seedlings, so that the situation is not easily caused that the seedling is mixed with bottom mud in a seedling raising pond under the action of liquidity of water, is covered with the bottom mud and dies of oxygen deficiency or intake nutritional ingredients are sufficient and accordingly the growth process of the seedling is influenced. Meanwhile, seedling raising racks are distributed in multiple stages at intervals, so that the seedlings are cultivated as many as possible. Growth between the seedlings is not influenced easily, so that the growth of the seedlings is not easy to inhibit, sufficient nutrients can be absorbed in the growth and development process of the seedlings, and the survival rate of the seedlings is improved while the growth speed of the seedlings is increased.

Description

technical field [0001] The invention relates to the technical field of pearl cultivation, and more specifically, relates to an artificial seedling cultivation method based on freshwater pearl cultivation. Background technique [0002] A pearl is, in several molluscs, a dense concretion formed in or under the mantle by the aggregation of layers of nacre around foreign particles not attached to the shell, having various shapes but most typically round, appearing Various colors, but usually white or light, with varying degrees of luster, can be used as decoration or medicine. According to the cause of formation, it is divided into two types: natural pearls and cultured pearls. Natural pearls mainly refer to pearls that are naturally formed in the body of shellfish and mussels; traditionally, people divide pearls into three types: seawater pearls, freshwater pearls, and artificial pearls. Seawater pearls are mainly produced in white butterfly shells and black butterfly shells. ...
