Introgressive hybridization is a movement of a gene from one species into the gene pool of another by repeated backcrossing an interspecific hybrid with one of its parent species. It is an important source of genetic variation in natural population. But the natural introgressive does not have the human direct interference while the exotic introgression is induced intentionally and very slowly. Transgenic technique is an extreme example of introgression verified as a successful hybridization from a transgenic plant to a wild relative. Carp is an important species of fish, but has low muscle quality. The study that focused on the feasibility improves the quality of muscle of carp by introgressive hybridization technology. In this constructed by transferring all-fish gene of shrimp to the zygote of common carp ) using mature micro-injection technology. AFLP technology was used to identify the transgenic zygote. The results of genotype of 30 pairs of AFLP markers and analysis of nutrient content of muscle showed that: (1) The gene of shrimp were detected in genome of transgenic carp by 30 pairs of primers of AFLP of shrimp which confirmed that the genomic fragment of shrimp exists in transgenic carp and has no found in contrast ones, then indicates that it should be feasible to transmit genetic material between two distant related species by transgenic method at molecular level. (2) The statistic analysis showed that the contents of crude protein of transgenic carps were 18.37%, 18.47% and 17.99%, which were higher than those in non-transgenic ones(17.06%). Total amino acids contents were f which 4 kinds of amino acids contents in transgenic carp <0.05), such as and alanine. So, the effects of shrimp gene directly transmitted to the carp genome gives rise to increase nutrient content and amino acids. This method would be useful in improving carp muscle quality and heredity base, and was a very powerful technology for DNA transferred between distant related species. In the future, more and more good trait of fish or other species would be improved by this technology, although this technique needs developing further. Transgenic fish will be
