Comparison of the apparent percent survival of unvaccinated Seymour steelhead smolts for the various experimental groups released from 2006–2009.

Percent survival was based on the number of detections between each segment of the migration from point of release, up to and including the POST arrays at the Northern Strait of Georgia (NSOG) and Queen Charlotte Strait (QCS). There were no significant differences (p>0.05) between the summer run and winter run steelhead from 2006-2008, therefore results from each strain were combined. Different letters within a row, indicate significant differences in survival were detected between the release segments for the combined FW release groups in 2006 and 2007(p
