Historical Medaka research entryEvidence by claimIndependent review ongoing

The 2014 catalog credits Masahiro Amano (Aichi Prefecture) with a dark-bodied Miyuki strain showing typical exterior light.

Overview

Black body coloration contrasts with the Miyuki-type external shine, whose visible tone can appear close to golden in some specimens. Historical creator/source attribution: Masahiro Amano / 天野雅弘.

Evidence labels refer to documentary strength. They do not assert independently tested genetics.

Known research gaps

  • The exact source parents and creator-preferred Latin transliteration still require confirmation.
  • Do not conflate all contemporary Black Miyuki stocks as individually authenticated descendants.
  • DNA-verified ancestry, independent inheritance ratios and authenticated present-day stock provenance require further source review.
  • No third-party photographs are rehosted without documented permission.
