Book excerpt: Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated in 2014 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 4,862 (SE 338) fish for the early run (16 May-30 June) and 13,952 (SE 492) fish for the late run (1 July-15 August). Methods and result from a second experimental sonar site located above tidal influence at RM 13.7 are presented in a separate report.

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.

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: In 2014, Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated using Adaptive Resolution Imaging Sonar (ARIS) at river mile 13.7. Net upstream passage of Chinook salmon greater than or equal to 75 cm as measured by ARIS was estimated to be 2,397 (SE 132) during the early run (16 May-30 June) and 10,871 (SE 291) during the late run (1 July-15 August). Net upstream passage of all Chinook salmon regardless of size was estimated to be 5,768 (SE 359) during the early run and 16,871 (SE 580) during the late run.

This book was released on 2016 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2013, Kenai River Chinook salmon (Oncorhynchus tshawytscha) passage was estimated using Adaptive Resolution Imaging Sonar (ARIS) at a newly established site at river mile 13.7. Medium and large Chinook salmon (greater than or equal to 75 cm as measured by ARIS) were directly assessed by the sonar, yielding net upstream passage estimates of 1,724 (SE 93) during the early run (17 May-30 June) and 12,656 (SE 282) during the late run (1 July-17 August). Smaller Chinook salmon (less than 75 cm ARIS length) overlap in size with other species; thus a combination of sonar, netting, telemetry, and weir data from this and other projects are required for assessing the abundance of all Kenai River Chinook salmon regardless of size. During the 2013 early run, telemetry and weir data were used to obtain a net upstream passage estimate of 2,806 (SE 341) small Chinook salmon; this estimate was combined with the ARIS estimate of medium and large Chinook salmon for a total of 4,530 (SE 353) Chinook salmon regardless of size. During the late run, a mixture model was fitted to sonar and netting data to obtain a net upstream passage estimate of 19,373 (SE 583) Chinook salmon regardless of size.

Net upstream passage of all Chinook salmon regardless of size was estimated to be 9,851 (SE 355) during the early run and 22,537 (SE 480) during the late run.

Book excerpt: Alaska Department of Fish and Game (ADF&G) has monitored Chinook salmon (Oncorhynchus tshawytscha) passage in the Kenai River using side-looking sonar technology from 1987 to present. The historical site at RM 8.6 used dual-beam (1987–1994), split-beam (1995–2011), and dual-frequency identification sonar or “DIDSON” (2012–2014) technology. Starting in 2013, ADF&G began operating adaptive resolution imaging sonar or “ARIS” at a new site located at RM 13.7. The RM 8.6 site was discontinued following the 2014 season in favor of data collection at the RM 13.7 site. This plan covers RM 13.7 project operations for the 2020–2022 seasons.

Net upstream passage of all Chinook salmon regardless of size was estimated to be 9,696 (SE = 371), 5,390 (SE = 318), and 6,033 (SE = 285), respectively, during the 2017–2019 early runs; and 24,436 (SE = 423), 25,143 (SE = 654), and 18,093 (SE = 547), respectively, during the 2017–2019 late runs.

This book was released on 2017 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 2014 through a 2-component process: (1) estimation of total fish passage with 120 kHz split-beam sonar and a dual-frequency identification sonar, and (2) apportionment to species by sampling with a suite of gillnets of various mesh sizes. An estimated 4,438,214 fish passed through the sonar sampling area between June 3 and September 7. Of those fish, 865,883 passed along the right bank and 3,572,331 passed along the left bank. Included, with 90% confidence intervals, were 103,613 ± 14,963 large Chinook salmon (>655 mm mideye to tail fork), 34,372 ± 7,931 small Chinook salmon (less than or equal to 655 mm mideye to tail fork), 1,924,425 ± 100,258 summer chum salmon, 650,808 ± 63,620 fall chum salmon, 247,047 ± 27,257 coho salmon, 513,599 ± 60,113 pink salmon, and 964,350 ± 83,573 other species.

This book was released on 2022 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive resolution imaging sonars (ARIS) are used to produce inriver abundance estimates of Kenai River early- and late-run Chinook salmon Onchorhynchus tshawytscha and Kasilof River late-run Chinook salmon. These sonars can be used to produce inseason estimates of fish 75 cm mid eye to tail fork length (METF) or longer, and when used over the entire run, can be used in conjunction with test fish data to produce postseason abundance estimates of all Chinook salmon regardless of size. Sonar estimates of Chinook salmon inriver passage provide the basis for estimating spawning escapement and implementing management plans that regulate harvest in the competing fisheries for these stocks.
