The Ito (Japanese Huchen (Danish Salmon)) is the biggest freshwater fish in Japan, and is found only in Hokkaido. It is approximately 1.0 to 1.5 meters in length. The Ito is in the salmon family, and is recognizable from other salmon in that its height from head to tail is relatively constant, while other species in the salmon family are more oval. There are different opinions as to the etymology of the name, Ito. A reliable story is that the body is like a thread (ito in Japanese). The Ito’s lifespan is longer than others in the salmon family, but they grow very slowly. For fishing enthusiasts, catching Ito is a rare occurance. They are on the red list for endangered species.
