Known research gaps

  • No independently inspected original breeder register, genotype assay or complete individual parent-fish mating ledger is available.
  • Source attribution and the historical year should not be interpreted as confirmed first retail sale date or authentication of present-day fish.
  • External catalogue images are not republished without separately verified copyright/reuse permission.
