Book excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.

This book was released on 2020 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: During 2017, Alaska Department of Fish and Game conducted salmon enumeration projects on the Chena, Salcha, and Delta Clearwater Rivers in the Tanana River drainage. Chinook salmon Oncorhynchus tshawytscha escapements for the Chena and Salcha Rivers were estimated using tower-counting techniques with the addition of sonar (DIDSON and ARIS) methodology as a secondary means of enumeration when events precluded visual counts. A Bayesian mixture model was used to apportion species from the sonar files. The Chena River counting tower and sonars operated from 26 June-3 August and the final escapement estimate was 5,235 (SE = 321) Chinook salmon. The adjusted sex composition was 0.67 (SE = 0.03) male and 0.33 (SE = 0.03) female (n = 420). The dominant age class was 1.3 for both males (28% of total sample) and females (46% of total sample). The Salcha River counting tower and sonars operated from 27 June-4 August and the final escapement estimate was 4,195 (SE = 205) Chinook salmon. The adjusted sex composition was 0.65 (SE = 0.07) male and 0.35 (SE = 0.07) female (n = 504). Like the Chena River, the dominant age class was 1.3 for both males (49% of total sample) and females (23% of total sample). Incomplete chum salmon Oncorhynchus keta escapement for the Chena and Salcha Rivers was estimated to be 21,176 (SE = 994) and 20,093 (SE = 1,220), respectively. Coho salmon Oncorhynchus kisutch escapement in the Delta Clearwater River was estimated as 9,617 fish by a visual boat survey at peak escapement on 26 October.
