Evolution of Goldfish
Goldfish, belonging to the Cyprinidae family of the Cyprinoid order in terms of Zoology, was originally produced in China. Up to the present, Goldfish is still reputed as Chinese Goldfish over the world. Goldfish is famous for its flamboyant color, Junoesque posture, and elegant swimming gesture, as well as quiet and tender temperament. It is described as the "fairy covered with golden scale" or "the peony in water" by Chinese people while crowned with "the oriental saint fish" by scholars in the West.
As far back as the Tang Dynasty (618-907), the fashion of "believing in Buddhism and abstaining the killing of living things" was prevailing. At that time, manyFangshengchi(pools for freeing captive animals) was constructed for breeding captured aureate crucians. As a result, the crucian under protection became a semi-cultivated pet fish. In the Song Dynasty (960-1279), fish cultivation transformed from semi-domestic breeding to domestic breeding, and Goldfish formally became a breed. It is until the last year of the Ming Dynasty (1368-1644), the cultivation of Goldfish enters its heyday, when the double tai-finned fish was cultivated. Since then, many varieties with odd shape and high ornamental value were brought into existence, such as bubble eye, "goose-neck, "reversed gill, and "pompon", etc.
In the Song Dynasty (960-1279), when the Goldfish cultivation transformed to artificial breeding, some varieties were spread to Japan. In the early 17th century, some varieties were introduced to Portugal and Britain. In 1728, the Netherlands started artificial propagation of Goldfish which soon prevailed across Europe. In the 18th century, it was introduced to the United States. At present, Goldfish has pervaded all over the world, with more than 300 definite varieties.
