Translated source passage (selection from the Japanese survey results):
Across two sampling visits to 28 study locations, researchers collected a total of 5,270 freshwater fish. Among them were 47 southern medaka (Oryzias latipes), representing 0.9% of the recorded catch. The authors also identified southern medaka as one of several fish species listed in national or Kagawa Prefecture red lists as threatened or near-threatened.
Context: This study's principal focus is Hemigrammocypris neglecta, an endangered cyprinid—not selective breeding or ornamental medaka. The medaka finding is an associated field observation.
Aquapedia takeaway (our original interpretation): Field records help document wild medaka habitats, but cannot be used to infer parentage or husbandry requirements for captive-bred ornamental varieties.
