DOWNLOAD EBOOKResults of a Yukon River sonar project, which provided estimates of Chinook salmon Oncorhynchus tshawytscha, chum salmon O. keta, and coho salmon O. kisutch daily passage on the Yukon River near Pilot Station, Alaska. Fish passage estimates for each species were generated in 2012 through a two-component process: (1) estimation of total fish passage with 120 kHz split-beam sonar and a Dual Frequency Identification Sonar (DIDSON), and (2) apportionment to species by sampling with a suite of gillnets of various mesh sizes.
