The present invention belongs to the field of shrimp selective breeding, specifically relates to the application
of a multi-level standardized breeding method within a family in shrimp selective breeding.
In shrimp selection breeding, standardized selection is extremely important, which has a great
impact on improving the accuracy and reliability of breeding.
The present invention by performing six-level standardized selection within the family line of each selective breeding group, in 6 different stages of growth and development, and finally determining the remaining seed individuals
in the family.
Using the method of the present invention, standardized selection is performed at different stages of shrimp growth and development, forming a multi-level standardized selection, with many selections, high selection intensity, and can retain various gene types as much as possible, so that genes with excellent traits can be retained to the greatest extent, and finally produce high-quality family groups, and further as a breeding group
.
The method described in the present invention has good practicability and operability, which is conducive to the further rapid development
of shrimp genetic breeding and aquaculture industry.
