Known research gaps

  • No complete original breeder parent-fish ledger or independent molecular genotype assay has been reviewed.
  • The listed creator/year do not authenticate present-day retail stock or independently establish first commercial sale.
  • Photographs on the specialist site are not licensed for reproduction and have not been copied.
