INTRODUCTION:

In 2004, scales from Lyons Ferry Hatchery fall Chinook broodstock were collected to address the following questions:

  1. How genetically distinct are the 2004 Lyons Ferry Hatchery broodstock from: 
    • Lyons Ferry Hatchery broodstock collected in 2002 and 2003,
    • Lyons Ferry Hatchery volunteers identified as yearlings collected in 2002 and 2003,
    • Lyons Ferry Hatchery volunteers identified as sub-yearlings collected in 2002 and 2003,
    • known naturally produced adults of unknown origin sampled at Lower Granite Dam in 2002 and 2003, and
    • a collection of fall Chinook collected from Umatilla Hatchery broodstock in 2003?

Results for the comparisons between the 2002 and 2003 samples are available in Kassler and Shaklee (2003) and Kassler et al. (2004). This memo; therefore focuses on the microsatellite DNA analysis of the fall-run Chinook salmon from Lyons Ferry Hatchery broodstock (04NM) and the comparison to the earlier samples.
