Overview
The Ehime-based breeder's own breeding-group gallery credits him for a sequence of ornamental Medaka lines. Its individual lineage accounts should not be interpreted as a claim over later third-party crosses.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| Breeder-group gallery attributes Kizakura, Yozakura, Mebina and Tarumi Long Fin lines to Tarumi | Breeder-group report | T1 ↗ |
| Specialist coverage documented Yozakura and Mebina by 2017; this is not proof of first release dates | Dated secondary coverage | T2 ↗ |
| Rinkou is described in the specialist catalog as a 2019 created line, while gallery context mentions earlier related fin traits | Catalog chronology; scope varies | T1 ↗ T3 ↗ |
| Mariage Long Fin is described as a Rinkou Long Fin × Morpho breeding project | Breeder-group report + specialist corroboration | T1 ↗ T4 ↗ |
| 2021 catalog date concerns a Mariage wide-fin variant and must not silently be assigned to the original Long Fin's first release | Variant/date distinction | T4 ↗ T5 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- Original dates for every selection and every named derivative are not independently established.
- Creator, collaborator and distributor roles must be checked for each derivative.
- No individual fish's genotype or inheritance ratios can be deduced from these descriptions.
