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.
