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

Known research gaps

  • Exact individually authenticated parent stock, all breeding generations and any stable genotype or inheritance ratio are unknown.
  • Historic year-group inclusion does not guarantee a breeder's actual first commercial sale year or present-day retail provenance.
  • Original fish photographs and source-owned images are not republished without explicit licensing.
