The recombinant plasmid pFV2cfGH was constructed using Growth hormone gene which was cloned from the channel catfish cDNA library,the β-action promoter of carp and the polyadenylation signal from the salmon growth hormone gene, and recombinant plasmid pFV2cfGH was microinjected into the fertilized eggs of the colorful crucian carp. 60 transgenic Colorful Crucian carps total DNA were got ,and growth hormone gene were detected by PCR. The result shows that the channel catfish growth hormone gene had been transmitted into the genome of the Colorful Crucian carp and the integration rate is about 47%.
