Book Description
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 2013 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 4,700,423 fish passed through the sonar sampling area between June 13 and September 7. Of those fish, 1,107,859 passed along the right bank and 3,592,564 passed along the left bank. Included, with 90% confidence intervals, were 105,433 ± 31,754 large Chinook salmon (>655 mm mid eye to tail fork), 11,726 ± 5,862 small Chinook salmon (less than or equal to 655 mm mid eye tail fork), 2,747,218 ± 119,519 summer chum salmon, 716,727 ± 77,556 fall chum salmon, 84,795 ± 20,744 coho salmon, 4,624 ± 6,361 pink salmon, and 1,029,900 ± 79,741 other species.

Book Description
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.

Book Description
Results of a Yukon River sonar project, which provided estimates of Chinook salmon Oncorhynchus tshawytscha, chum salmon O. keta, and coho salmon O. kisutch daily passage on the Yukon River near Pilot Station, Alaska. Fish passage estimates for each species were generated in 2011 through a two-component process: (1) estimation of total fish passage with 120 kHz split-beam sonar and a Dual Frequency Identification Sonar (DIDSON), and (2) apportionment to species by sampling with a suite of gillnets of various mesh sizes.

The Pilot Station sonar project has provided daily passage estimates of 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 2019 using a 2-component process: (1) estimation of total fish passage with 120 kHz split-beam sonar and an adaptive resolution imaging sonar, and (2) apportionment to species by sampling using a suite of gillnets of various mesh sizes. An estimated 3,161,920 fish passed through the sonar sampling area between June 2 and August 31. Of those fish, 690,494 passed along the right bank, and 2,471,426 passed along the left bank. Included, with 90% confidence intervals, were 172,242 ± 18,964 large Chinook salmon (>655 mm to fork of tail), 47,382 ± 7,725 small Chinook salmon (≤655 mm to fork of tail), 1,402,925 ± 85,902 summer chum salmon, 842,041 ± 37,151 fall chum salmon, 86,401 ± 9,530 coho salmon, 42,353 ± 8,893 pink salmon, 270,434 ± 36,596 cisco, 196,905 ± 30,456 humpback whitefish, 25,694 ± 5,256 broad whitefish, 22,673 ± 5,948 sheefish, and 52,870 ± 5,659 other species.
