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. |
