Chinook Salmon Escapement Estimation on the Campbell and Quinsam Rivers in 1984

Category : Chinook salmon
Languages : en
Pages : 52
Book Description
The chinook escapement to the Campbell and Quinsam Rivers in 1984 was estimated by using a simple carcass tagging method. Marked carcasses from the Quinsam hatchery were released on 2 occasions in each river and the proportion of these carcasses recovered in the dead pitch was used as an index of the effectiveness of the dead pitch. In this report, the theory behind the use of carcass tagging is examined and the expected levels of precision and the potentials for bias are assessed. Two different estimation methods are examined, one based on a Petersen approach and the other on the Schaefer method, and the need for corrections for differences in the sex ratio between live sampling and dead sampling is discussed.
Salmonid Field Protocols Handbook
Author: David H. JohnsonPublisher:
ISBN:
Category : Nature
Languages : en
Pages : 504
Book Description
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.
