Medaka strainEvidence by claimIndependent review ongoing

JOURAKUAN describes LU-04 as an independently selected branch of WI-01 × Rinkou, with roughly seven generations of further selection.

Overview

The original 2022 breeder article distinguishes LU-04 from WI-03. It is a numbered breeding line within the wider exterior-light tricolor-lame program, not a separately verified genetic species. Documented developer/creator role: JOURAKUAN / 静楽庵.

Recorded lineage inputs

WI-01 selected tricolor exterior-light / Rinkou

These are historical breeder-reported founder inputs or longer selection stages, not individually sequenced parents. Review the source J03 for its original scope and missing generations.

Known research gaps

  • No fully authenticated breeder pairing register or inheritance study establishes exact per-generation outcomes.
  • The 2022 article date alone is not proof of a 2022 first commercial release.
  • DNA-confirmed ancestry, Mendelian segregation, complete parent-pair registers and strain-specific water requirements are not established.
  • Images from magazine, breeder sites and shop listings are not republished without verified reuse permission.
