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.

Book excerpt: Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated in 2013 at RM 8.6 using dual-frequency identification sonar (DIDSON). Estimates of midriver Chinook salmon passage between and at least 3 m from the transducers were 1,439 (SE 138) fish for the early run (16 May-30 June) and 15,185 (SE 566) fish for the late run (1 July-15 August). The early-run estimate is too small to explain weir counts at upriver tributaries. Methods and results from a second experimental sonar site located above tidal influence at RM 13.7 are presented in a separate report.

This book was released on 2020 with total page 78 pages. Available in PDF, EPUB and Kindle. 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. Included, with 90% confidence intervals, were 112,605 ± 49,275 large Chinook salmon (>655 mm mideye tail fork), 25,294 ± 36,165 small Chinook salmon (=655 mm mideye tail fork), 1,423,372 ± 89,356 summer chum salmon, 458,103 ± 40,797 fall chum salmon, 177,724 ± 12,489 coho salmon, 919,036 ± 63,942 pink salmon, 281,456 ± 37,151 cisco, 175,749 ± 21,348 humpback whitefish, 19,835 ± 6,581 broad whitefish, 49,250 ± 31,895 sheefish, and 41,164 ± 29,700 other species.
