Popis

This project examines the factors influencing fish populations including habitat, harvest, hatcheries, hydropower system operations, and climate change. It seeks to estimate impacts of these factors on Wenatchee River basin spring Chinook salmon through the use of the Shiraz life cycle model parameterized for this fish population. An evaluation of a suite of habitat restoration actions will be conducted, a reparameterized model to incorporate supplementation effects will estimate the impacts on wild fish from hatchery operations, and the influence of climate change as estimated from several bracketing Global Climate Models (and their basin impacts determined via DHSVM modeling) will be examined. The Shiraz and climate modeling work is led by Dr. Jon Honea at Emerson College (Boston, MA), an external collaborator who began this work in a post-doctoral position at the NWFSC. Model
