Summary
Description
In an attempt to address the concerns raised as a result of the marking of the 2004 brood at Warm Springs NFH, a study plan was developed to evaluate the use of an automated marking trailer at Warm Springs NFH. An automated marking trailer and a manual marking trailer were used to mark and codedwire tag the brood year 2005 spring Chinook salmon at Warm Springs NFH. In this report, we compare tag retentions, mark quality, injury rates, and marking to release mortality between fish marked and tagged using an automated trailer and fish marked and tagged using a conventional manual trailer. A future report will look at releasetoadult survival rates.
