Scientists Discover Rare Chinese Bahaba in Hong Kong’s Waters After 10-Year Elusion
Environmental DNA Confirms Rare Fish Return
The Chinese bahaba is back.
Often dubbed the “Panda of the Sea,” the critically endangered fish has been confirmed present in Hong Kong’s waters after more than a decade of eluding scientific capture. Recent research utilizing advanced environmental DNA technology unearthed traces of the fish’s genetic material across various western bays, marking a major breakthrough for non-invasive marine population monitoring and regional conservation efforts.
Decade of Silence Broken by Genetic Sampling
For more than ten years, marine biologists struggled to locate physical specimens of the Chinese bahaba in local municipal waters. Traditional fishing surveys and visual sightings routinely came up empty.
Then came the shift.
Researchers collected seawater samples across multiple western bays in Hong Kong. By extracting and sequencing shed genetic material—such as mucus, skin cells, and waste—left behind in the marine ecosystem, the research team definitively proved that the species still inhabits the area. This methodology bypasses the need to capture or physically disturb the rare animals, establishing a powerful framework for aquatic wildlife management.

Standard visual surveys are no longer sufficient to clear a marine zone for development if microscopic evidence proves the presence of a critically endangered species.
