Embodiment Construction

[0028] As described above, the problems to be solved by the present invention and the means for solving the problems, including the effects of the invention and specific items, are included in the examples and drawings described below. The advantages and features of the present invention, as well as the method for realizing them, will be clear with reference to the accompanying drawings and the detailed implementation examples described later.

[0029] First, if Figure 1 As shown, the first stage S1 involves the fertilization of diploid female eggs with diploid male sperm.

[0030] Next, the second stage S2 consists of preventing the release of the first polar body or the second polar body of the zygote from said first stage S1, resulting in triploid females.

[0031] Next, the third stage S3 involves fertilizing the egg of said second stage S2 female with diploid male sperm.

[0032] Second, the fourth stage S4 consists of preventing the release of the first polar body fro...

Abstract

The invention relates to a production method of triploid shellfishes, in particular to a production method of the triploid shellfishes from diploid shellfish production to tetraploid mother shellfish production to triploid shellfish production. The production method is characterized by comprising the following steps of S1, a first stage of fertilization of diploid female eggs and diploid male sperms; S2, a second stage in which the release of a first polar body or a second polar body of fertilized eggs is prevented in the first stage S1 and triploid females are produced; S3, a third stage in which the female eggs in the second stage S2 are fertilized with the diploid male sperms; S4, a fourth stage in which the release of the first polar body is prevented from occurring from the eggs of the third stage S3 and tetraploid males are produced; and S5, the fifth stage in which the diploid female eggs are fertilized with the male sperms in the fourth stage S4, and the triploid shellfishes are generated.

Description

technical field [0001] The present invention relates to a production method of triploid shellfish, and in detail relates to the production method of triploid shellfish from the production of diploid shellfish to the production of tetraploid female shellfish to the production of triploid shellfish. Background technique [0002] The production of marine shellfish in the world is 16,043 tons, of which oysters account for about 3.6%, or 583 tons, and shellfish including oysters account for about 4.5%. [0003] As mentioned above, oysters are an important cultured species in the world. Due to long-term thermalization of oysters, insufficient food organisms due to over-density breeding, oysters grow low, and abnormal sea conditions (high water temperature, oxygen deficiency) cause a large number of deaths and cause serious problems. crisis. [0004] In order to solve the above-mentioned technical problems, the oyster seed production industry and the aquaculture industry are inter...
