Leatherback carp (Kawagoi) had few or no scales, whereas the mirror carp (Kamamigoi) displayed large symmetrical scales along its back, either side of the dorsal fin. Some mirror carp displayed scales along their lateral line as well, and these are sometimes referred to as striped carp (Yoroigoi). Other varieties produced scales in irregular patterns reminiscent of ancient Japanese armor. The first successful crosses between the German carp and the Japanese carp were made in 1904. All varieties were to be known as Doitsu Nishikigoi. These modern varieties contributed greatly to the expansion of Nishikigoi throughout the world.
ided the last part of the jigsaw the Ogon Following on from the uk business email databaseTaisho Sanke came the Showa Sanshoku Sanke (later called Showa), and along with it the end of the Taisho era. In 1927, the Showa Sanke made its debut, primarily a black koi with patches of red and white, unlike the Taisho Sanke, which is a white koi with patches of red and black. In the early 1920s, a wild carp with golden scales was crossed with a koi in a breeding program to produce the greatest amount of golden color.
By 1946, the first Ogon (golden koi) was produced. The name “Ogon” initially referred only to the gold form, but today it applies to all single-color metallic koi. Ogons are included in the category Hikarimoyo (abbreviated from Hikarimoyo-Mono; Hikari meaning “shining” and mono denoting a single color). The exception to this category is the Matsuba Ogon. Although this koi variety is predominantly one color, its scalation is enhanced with black edging to the scales. This produces the famous “pinecone” pattern, so popular with hobbyists To put koi breeding into perspective, it is only very recently that modern varieties, such as Matsuba Ogon (1960s), Gin Matsuba (Platinum Ogon).
