It belongs to the crucian carp species, Cyprinidae, Cyprinidae and Crucian carp belonging to the genus Carp, Cyprinus carpio and Carassius auratus, which have been closed for a long time in the special environment of Guizhou plateau. It is a precious fish germplasm resource in Guizhou. In 1985, Shanghai Fisheries Research Institute carried out a more comprehensive study on the fish. In 1988, the original fish was designated as “Natural gynogenetic silver carp” by the experts of the State Aquatic Product Administration. The oxytocin is a key link in artificial breeding and also the technical basis for the industrialization of seed production and breeding of Pu’an silver crucian carp. At present, Pu’an silver crucian carp mainly adopts natural breeding, but there is more fertilization rate in natural breeding
