Historical records of court goldfish

In the Compendium of Materia Medica in Chongzhen, Ming Dynasty, it is inferred that the ancestor of goldfish said, "When you visited Lushan Mountain in Huanchong, you saw red-scaled fish in the lake, and so on." . This is also the earliest time to find "red fish" in the existing data, with a history of about 1700 years. Li Shizhen also recorded the varieties of goldfish, such as carp, crucian carp and loach, among which "loach" is the rarest and "golden crucian carp" is the most durable. There have been livestock since the Song Dynasty, and now people are raising people to play everywhere. "In the Song Dynasty, goldfish were mainly golden orange common crucian carp." "Golden crucian carp" was the original name of goldfish. At that time, people were full of mystery about the bright colors of crucian carp During the reign of Song Kaibao (AD 968), Ding Yanzan, the third secretariat of Xiuzhou (Jiaxing) of Wu Yueguo, discovered golden crucian carp in a pool outside Jiaxing, which was changed to a release pool. Besides Carassius auratus, there are other fish and turtles in the pond, all of which are prohibited from fishing. Since the Song Dynasty, most of the golden crucian carp have been transported to the small ponds of officials and nobles, and the fish farming industry has emerged. In Historical Records written by Sun, a patriotic general in the Southern Song Dynasty (12 14), there is an interesting story about Rao: "Today, fishermen can exchange fish for gold, crucian carp is the best, followed by carp. You can dig stones to make a pool and play in your room. Asked about this matter, the secret refused to say. Or the cloud feeds all the fish with the little red worms in the city passage for one hundred days. White as silver at first, yellow as yellow at second, and golden for a long time. I haven't had time to test it. Don't have ink-printed bright paint, such as hawksbill fish, whose literary talent is particularly impressive. "At that time, goldfish had crucian carp and crucian carp, but why do people think that the ancestor of goldfish is crucian carp, not carp? Modern scientific research has proved this point. Japanese biologist Ishihara and others used the serum of goldfish and crucian carp for precipitation reaction test, which proved that goldfish and crucian carp belong to the same species. Professor Marco from China also pointed out that crucian carp and goldfish belong to the same scientific name. ) and Wu's "Lu" (A.D. 124 1 274) both record the industry of keeping and selling goldfish-live fish, and feeding goldfish with red worms and shrimps in urban sewage pits. Fish pay attention to choosing different goldfish, and unconsciously began artificial seed selection and preservation. However, in the Song Dynasty, golden crucian carp was still wild, and fish farming in Danxutang was not affordable for ordinary people, and the variation of golden crucian carp was very slow.
