Genetic analysis to inform bull trout movement patterns in the Yakima Basin


ABSTRACT: Bull trout movement patterns are largely unknown in the Upper Yakima River, and little data is available to inform spatial and temporal habitat use. However, the Service is in possession of a small number of genetic samples (n=25) collected at and near Roza Dam, which is located approximately halfway between the Upper Yakima and Naches Rivers local populations of bull trout. The Yakima core area is the largest core area in Washington located wholly within the state. Analysis of these samples would inform which local populations make movements within the vast Yakima Basin and whether there are interactions with bull trout from adjacent core areas, and would be extremely valuable to Mid-Columbia recovery unit consultation [...]
