Traditional animal resource protection measures are mainly delineating protected areas or establishing conservation bases. These measures can well protect species diversity, but there are also some shortcomings: the area of the protected area is large, and poaching is repeatedly banned; establishment of good breeding bases for protection Local breeds have large investment and long time, and are prone to inbreeding, species decline and other phenomena. The advent of new achievements in biotechnology, such as test tubes, cloning, and cryopreservation, has opened up new ways for the protection and utilization of animal genetic resources. "Ark" is no longer heaven and earth. What does this text mainly introduce?
