—Juvenile Chinook salmon Oncorhynchus tshawytscha emigrating from natal tributaries of the Sacramento River must negotiate the Sacramento–San Joaquin River Delta, a complex network of natural and man-made channels linking the Sacramento River with San Francisco Bay. Natural processes and water management actions affect the fractions of the population using(More)
ii Acknowledgements The authors would like to give special recognition to Jim Norris and Ian Fraser of Marine Resources Consultants who were central in the development of this program and continue to play a central role in the ongoing monitoring. They and their other staff that crew the field vessels showed great dedication and spent many hours of ship time(More)
Populations of juvenile salmon emigrating from natal rivers to the ocean must often traverse different migratory pathways that may influence survival. In regulated rivers, migration routes may consist of a network of channels such as in the Sacramento-San Joaquin River Delta, or of different passage structures at hydroelectric dams (e.g., turbines or(More)
Acoustic telemetry is a widely used tool for evaluating the behavior and survival of juvenile salmonids in the Columbia River basin. Thus, it is important to understand how the surgical tagging process and the presence of a transmitter affect survival. This study evaluated the effect of fish length on the survival of yearling and subyearling Chinook salmon(More)
iv Acknowledgements The authors would like to give special recognition to Jim Norris and Ian Fraser of Marine Resources Consultants (MRC) who continue to play a significant role in the ongoing monitoring and success of the project. Marine Resources Consultants showed great dedication and logged many hours of ship time collecting data for the project. Betty(More)
Acoustic-tag studies with their high to very high detection rates defy traditional statistical wisdom regarding analysis of tagging studies. Conventional wisdom has been to use a parsimonious model with the fewest parameters that adequately describes the data to estimate survival parameters in release-recapture studies in order to find a reasonable(More)

The purpose of this document is to offer guidelines and identify opportunities for standardizing important aspects of smolt survival studies. We examine terminology, field methods, analytical frameworks, and reporting techniques, including suggestions to improve communication between managers and investigators. Each year considerable funds and effort are(More)
