Embodiment Construction

[0020] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0021] A method for breeding improved fish species, comprising the following steps:

[0022] a. Selection of broodstock: 200 pairs of largemouth bass were collected, and the genetic analysis of these largemouth bass was carried out using microsatellite markers developed in our laboratory. The analysis results showed that these fish had high genetic diversity. Then select 100 pairs of broodstock that are active, good in heredity, and 15-20% larger than the average body weight as alternative parents.

[0023] b. Grouping of parents: pairing of male and female parents, the ratio of male and female parents in each group is 2:1.

[0024] c. Parental marking: PIT electronic marking is used to mark...
