Lineage review · Batch 018: Source-described breeder lineage, selected family, or morphology stage is illustrated with dashed documentary links. These are not parent-fish certificates or DNA-tested inheritance. Specialist record ↗
Overview
The breeder association describes selection for yellow coloration and contrasting white body coloration alongside exterior light.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| Masaharu Tarumi is credited as creator of Kizakura | Breeder-group primary report | T1 ↗ |
| The described program involved nontransparent red-and-white or tricolor stock with Miyuki | Breeder-reported foundation, exact generations unspecified | T1 ↗ |
| Yellow/white contrast and Miyuki-style exterior light are distinguishing selection goals | Reported phenotype description | T1 ↗ |
| Original public first-release year remains undetermined | Date not established by reviewed source | T1 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- Kizakura Hikari and other named derivatives must not be conflated with the original line.
- Fish-specific genetic testing, validated inheritance percentages, exact water optima and universal grade thresholds have not been established from these cited histories.
- Breeder-authenticated, licensed photos and individual parent provenance remain a separate editorial requirement.
