Asian Masu Salmon: An Introduction to the Species, Key Threats and the Urgent Need to Assess Their Status

Masu salmon Oncorhynchus masou (known also by the common name cherry salmon) distribution extends from Korea to the Kamchatka peninsula in northeast Asia.  There are a number of closely related species and subspecies, including the critically endangered Formosa landlocked salmon which is restricted to a single headwater stream in Taiwan (O. formosanus).  Based on genetic evidence, the species is thought to be a progenitor of the Pacific salmon genus.  It is, however, little known in North America.  The overall objective of this session is to introduce this species to a very curious audience at an American Fisheries Society gathering, and draw contrast and analogies to species here in North America, particularly coho (O. kisutch) and rainbow/steelhead (O. mykiss).  I will introduce the species, including some basic descriptions of its distribution and life history.  I will also outline some key threats to the species, and justify the need to carry out a range-wide assessment of their current status to be included in the IUCN Red List of Threatened Species.
