Fish passage research by a Bozeman-based team will soon be published in Northwest Science. The journal has accepted “Sprint Swimming Performance of Shovelnose Sturgeon in an Open-Channel Flume,” authored by Luke Holmquist of MSU’s Department of Ecology, Kevin Kappenman of the US Fish and Wildlife Service, Matt Blank of WTI, and Matt Schultz. The article describes research in an outdoor experimental flume at the Bozeman Fish Technology Center. The sprint velocities from the laboratory study indicate that the swimming capability of shovelnose sturgeon has been previously underestimated. The results of this study provide data that might support design and analysis of fish passage projects for shovelnose sturgeon and other sturgeon species.

WTI Research Scientist Matt Blank has been on the road this spring, presenting findings of fish passage research at several leading conferences. Along with his colleagues from the MSU Ecohydraulics Research Group and the US Fish and Wildlife Service, he was invited to speak at both the Annual Meeting of the Western Division of the American Fisheries in May, and at the International Conference on Engineering and Ecohydrology for Fish Passage in June. Topics for these presentations included:
· A Baseline Swimming Assessment for Arctic Grayling: Characterizing the Volitional Swimming Performance of Arctic Grayling to Inform Passage Studies
· Arctic Grayling and Denil Fishways: A Study to Determine How Water Depth Affects Passage Success of Arctic Grayling through Denil Fishways
· Swimming Performance of Sauger in Relation to Fish Passage
The research team conducts studies at MSU, at the Bozeman Fish Technology Center, and in the field. Their studies explore how irrigation installations, flow management structures, and other infrastructure serve to prevent, limit, and allow successful fish passage for various species. The findings can inform design improvements and conservation efforts for species of concern.
