Book excerpt: "A fixed-location split-beam hydroacoustic study was initiated in 1994 to assess the population abundance of adult fall chum salmon Oncorhynchus keta in the Chandalar River, a tributary of the Yukon River. Annual passage estimates have been made since 1995 and daily in-season counts have been provided since 1996. This report presents the results for the 2002-2006 seasons and describes the annual variability in run size and timing"--P. [1].
