Nisqually Stock Management:  Why Change? Nisqually Natural Spawning Escapement Approx. 70% pHOS will not lead to Local Adaptation
How do we re-establish a wild Nisqually stock while still providing harvestable numbers of hatchery fish?
Utilize Mainstem Weir to Control Hatchery Composition on Spawning Grounds
Fish Auger
Old Technology
Modify Broodstock Management to Support Local Adaptation ,[object Object],[object Object],[object Object],Approach:  Initiate hatchery program where the natural environment drives adaptation, reducing the impact of hatchery spawners on natural fitness
