Chinook salmon provide for important aboriginal, subsistence, personal use, commercial, and sport fisheries throughout the entire Yukon River drainage, as summarized in the most recently published yearly management reports (Bue et al. 2011) and U.S./Canada Joint Technical Committee reports (JTC 2011). G.Sandone Consulting, LLC, in cooperation with the Little Salmon Carmacks First Nation, and the Department of Fisheries and Oceans, Canada will sample spawned out, predominantly live Chinook salmon within the Little Salmon River drainage, Yukon, Canada, to estimate the age, sex, length (ASL) of the spawning population within that drainage. The Little Salmon is a tributary to the Yukon River with the confluence with the Yukon River near the village of Carmacks, Yukon.
