Purpose
Establish a primary-source baseline for Aquapedia's Medaka counting and breeder/strain provenance work. This note deliberately separates
1. the broad universe of improved Medaka types/house names,
2. JMA's formally recognized numbered new varieties,
High-confidence counting conclusions
For the Medaka progress ledger, use separate fields
JMA numbered recognition catalog — primary-source baseline
Rows 1–40 below are transcribed from JMA's official compiled list. No. 41 is added from its official standalone recognition page because the compiled list has not yet incorporated it. [S1][S8]
JMA's No. 40 page and compiled list both spell the variety name フラックアースアイラメスワローロングフィン. This looks like it may be a source typo for ブラック..., but Aquapedia must preserve the exact primary-source spelling and should not silently correct it. Add an alias/correction only after a later official source resolves it. [S1][S7]
Current-system deepening: Nos. 36–41
Evidence semantics: verifiedprimary means the claim is directly represented in an official JMA source. It does not mean applicant-reported fixation percentages, pedigrees, inheritance observations, or creator narratives were independently reproduced or genetically validated by Aquapedia. Preserve those as source-attributed claims unless separate evidence corroborates them.
C -->|F2: no combined RLF+Swallow| D[Swallow backcross]
D -->|F2B1: combined phenotype observed| E[燕 / Tsubakuro]
Important data-model distinction
This distinction is necessary because JMA itself states >700 improved Medaka types existed by 2022 while the numbered recognition program contains only a much smaller curated subset. [S1][S2]
JMA list synchronization conflict
S1 currently shows Nos. 1–40 and stops at Devil. S8 is an official JMA page explicitly titled No. 41 and states that it is JMA-recognized. The correct Aquapedia treatment is
Research next queue
1. Parse the 2025 fifth-edition classification manual and identify all new traits/terminology added since 2024, especially the final handling of the クリスタル phenotype.
2. Create normalized records for all 41 JMA numbered recognitions with source IDs, Japanese names, readings, creators, dates, former/current standardized names and aliases.
3. For each creator in the 41-row catalog, run the required exhaustive strain search audit against breeder-owned media, events, catalogs, interviews and archived posts. JMA recognition is only one discovery path.
Exhaustive strain search audit
This dossier is not an exhaustive catalog of Medaka breeders or strains. It is an official-recognition baseline.
