Selected by experts since Poro-numa pond has a unique brackish environment.
This is the area around the shore zone of the Poronuma wetlands in Hokkaido’s Sarufutsu Village. Poronuma, adjacent to the coast and connected to the mouth of the Sarufutsu River, is home to a unique environment as a brackish lake, and it strongly retains the features of its primeval nature. Distribution of Hucho perryi and other organisms inhabiting this highly natural environment can be seen starting at its mouth, and it also has been confirmed to be a habitat for Deiratonotus cristatum, indigenous Assiminea septentrionalis, and others.
