Pfisterer, Carl, 2012, Yukon River fisheries estimation: no. Personal Communication.
Summary
Spoke with Carl for about 20 minutes about what ADF&G biologists have done since the 2010 action plan with regard to improving sonar counts. He told me about two main efforts - tagging in Mt Village and hydrophoning at Pilot Station, and also the use of side scan sonar--deployed from an anchored boat to check the middle of the river.
