Introduction
Conclusions
Prosser Dam
Roza Dam SH
SH Population
Resident Trout
3) Identify if resident trout samples collected above Roza Dam
are different genetically from the steelhead collections from
Roza Dam 
Roza Dam Steelhead
Project Objectives
Why?
•  Considerable attention recently has focused on the reproductive
   interactions between resident rainbow trout and steelhead
•  If interbreeding is extensive, then the two forms should be
   similar genetically
Considerable attention recently has focused on the reproductive interactions between resident rainbow trout and steelhead.  In some areas in the Pacific Northwest interbreeding between the two forms appears extensive (Araki et al. 2006)
