Brian Bellgraph’s professional interests and research focus on the ecology of freshwater and estuarine fishes. Mr. Bellgraph utilizes cutting-edge methods to assess the survival and behavior of juvenile and adult fishes in relation to anthropogenically modified aquatic systems. His specialties include movement and behaviors of large-river fishes, intra-guild resource overlap, fish passage, and the impacts of energy development on fish populations. Current and recent research projects include evaluating the survival and migration delay of juvenile salmon emigrants, determining fine-scale movements of bull trout at a hydroelectric dam to provide biologically-based construction criteria for a fish passage facility, and relating estuarine and reservoir hydrodynamic conditions to fish behavior. He uses his expertise with the JSATS and radio telemetry technologies to estimate juvenile salmon survival and evaluate fish behavior for numerous projects.
