Tobias J Kock
Tobias Kock is a Supervisory Research Fish Biologist at the Columbia River Research Laboratory (CRRL) in Cook, Washington. His research team works on studies focused on Pacific salmon, dams, fish ecology, and salmon reintroductions throughout the western United States. His research is highly collaborative and typically involves State, Federal and Tribal partners.
Tobias Kock's research team conducts investigations into dam passage and survival for juvenile and adult Pacific salmon, assesses fish collection and passage devices, researches the ecological effects of high-head dams and reservoirs on anadromous fish, and evaluates various aspects of salmon and steelhead reintroductions upstream of impassable dams. He is currently working on studies that evaluate the effects of flow management on juvenile salmon survival, the responses of adult salmon and steelhead to trap-and-haul, assessment of dam-passage survival of juvenile salmon, and developing methods to estimate survival of salmon fry in reservoirs. His research is highly collaborative. Kock works closely with Tribal, State and Federal partners to provide unbiased science for use by a diverse group of partners in several watersheds across the western United States.
