Oncorhynchus masou is a species of landlocked salmon survived since the Ice Age, and its origination and classification has been widely studied. After the WWII, human damage and natural factors have deteriorated the environment of its habitat. It can only be occasionally spotted in Chichiawan River and 7 km long course at the downstream of Hsuen Shan River. Its population was significantly reduced to few hundreds, and became endangered. The government has listed it as protected species and promoted artificial restoration and release to increase its population.
