Graduate student Nick Hahlbeck is working on this project. Our preliminary research has yielded exciting results some of our radio-tagged fish travelled over 300 km in a single year, moving among habitat patches that support specific functions, such as coldwater refugia, foraging, and spawning.
We are exploring how these fish move across the watershed to exploit seasonally complimentary habitats.
Much of this watershed becomes uninhabitable for salmonids during summer, as water temperatures exceed 25 degrees C, pH reaches >9.5, and dissolved oxygen often dips below 3 mg/L. My lab is collaborating with the Oregon Department of Fish and Wildlife (ODFW) and other groups to study the seasonal movements and energy budgets of redband rainbow trout in the Upper Klamath Basin.
