Koi Varieties - Koi Breeders Direct

Short for Showa Sanshoku or Showa Sanke, a black Koi with red and white patches named for its development in the Showa era.

Whereas Kohaku and Taisho Sanshoku have red and/ or black markings on the white ground, Showa Sanshoku have red markings on white patterns formed on the black background. We have discerned such different arrangement by observing the processes of fry development.

Kohaku and Taisho Sanshoku are almost completely white when freshly hatched. Young fry of Showa varieties (including Showa Sanshoku, Shiro Utsuri and Hi Utsuri, etc.), on the other hand, are almost completely black when just emerged from eggs.

As days go by, white patterns become visible against the black background, and red markings will soon appear on the white patterns. We should, therefore, say that Showa Sanshoku have black texture.
