Book excerpt: The Pilot Station sonar project has provided daily passage estimates for Chinook (Oncorhynchus tshawytscha), chum (O. keta), and coho (O. kisutch) salmon for most years since 1986. Fish passage estimates for each species were generated in 2010 using a 2-component process: (1) estimation of total fish passage using 120 kHz split-beam sonar and a dual-frequency identification sonar (DIDSON), and (2) apportionment to species by sampling using a suite of gillnets of various mesh sizes. An estimated 3,683,588 fish passed through the sonar sampling area between June 1 and September 7. Of those fish, 662,329 passed along the right bank and 3,021,259 passed along the left bank.
