Book excerpt: Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated in 2012 using dual-frequency identification sonar (DIDSON). Estimates of midriver Chinook salmon passage between and at least 3 m from the transducers were 3,228 (SE 191) fish for the early run (16 May-30 June) and 21,613 (SE 667) fish for the late run (1 July-15 August). DIDSON units temporarily deployed shoreward of the left and right bank transducers recorded large Chinook salmon (equal to or greater than 75 cm) migrating outside the standard insonified zone. The efficacy of installing sonar at river mile 13.7 was investigated and confirmed.
