Translated source passage (selection from the Japanese section on reintroduction):
A further concern in reintroduction programs is genetic disturbance. If individuals that are genetically different from a native wild population are deliberately released into the environment, they may disrupt the original genetic structure of that population.
Context from the source: The authors specifically mention northern medaka (Oryzias sakaizumii) and southern medaka (O. latipes) among documented concerns regarding the release or escape of artificially propagated or pet-related animals.
Aquapedia takeaway (our own analysis, not translated source text): Never release ornamental medaka into natural waterways. Treat genetic lineage in domesticated strains as separate from the conservation genetics of wild populations. This is not evidence of a particular ornamental-strain cross.
