A collaborative research team from Toho University, the Japan Fisheries Research and Education Agency, Nihon University, the Global Environmental Forum, and the Museum Park Ibaraki Nature Museum has revealed that a newly introduced parasite is infecting native fish in the Tone River system. Their study also confirms that the golden mussel, an invasive species, acts as the infection source, while non-native fish such as bluegill and channel catfish help sustain the parasite’s life cycle.

This study was published in the Journal of Helminthology on January 20, 2025.
