Embodiment Construction
[0027] Such as figure 1 , figure 2 As shown, in this embodiment, the golden-yellow snakehead formed by the mutation of the snakehead is used as the material, and it is cultivated by the closed-generation selection method. In this example, in the aquaculture base of Jiangsu Agriculture and Forestry Vocational and Technical College, golden yellow snakeheads were selected from individuals with variation in body color of the snakeheads, selected for breeding, and multiplied. Strong disease resistance, good meat quality, stable low temperature resistance, good growth and development, relatively consistent genetics, and a new variety (strain) of golden yellow snakehead. The concrete breeding method of this snakehead is as follows:
[0028] (1) Parent selection and cultivation. The golden-yellow individuals with body color variation appearing in the regular snakehead population were selected as parents. It is required to select individuals with a body color that is obviously dif...
