Whatever the reason, or as a result of the combination of both qualities, Niigata attracted the most famous names in koi breeding to the area. There is no record of what was the first koi mutation, but it is thought to have been a red carp called “Hoo-kazuki,” possibly from a mutant black carp. From this original red carp mutation the first white koi was produced. These were subsequently crossbred, resulting in the first red-and-white carp, originally called “Hara-aka,” meaning red belly. The red-and-white carp is the oldest and still by far the most popular colored variety in Japan.


It was not until much later, in about 1890, that it was officially recognizedemail database australia and named Kohaku koi. nidan kohaku Nidan Kohaku However, it is accepted that the Kohaku line was only stabilized in Niigata in about 1930. Although red-and-white koi were the most talked about mutation, other colored carp were being developed. It was not long before the true all-black “Magoi” was produced from the original two strains of wild carp: one brown/black, the other a blue/black. From this early mutation came the first known true blue koi, the Asagi, meaning “light blue.




” Much later, an Asagi Sanke was carp and the first Shusui (meaning “autumn water”) was bred. A Shusui is said to represent the reflections of red autumn leaves floating against a pure blue sky. During this early time, before the science of genetics had been developed, breeders gained important knowledge of how to maintain these unusual colors and improve on them. But even now, with strong bloodlines going back over many years, it is still difficult to predict the resultant brood from a successful spawning.
