 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. |
