Downstream Movement of Fall Chinook Salmon Juveniles in the Lower Snake River Reservoirs during Winter and Early Spring

Autor: Tobias J. Kock, Frank L. Mullins, R. Kirk Steinhorst, William P. Connor, Kenneth F. Tiffan

Publikováno v: Transactions of the American Fisheries Society. 141:285-293

We conducted a 3-year radiotelemetry study in the lower Snake River to (1) determine whether juvenile fall Chinook salmon Oncorhynchus tshawytscha pass dams during winter, when bypass systems and structures designed to prevent mortality are not opera

Use of Statistical Bootstrapping to Calculate Confidence Intervals for the Fall Chinook Salmon Run Reconstruction to Lower Granite Dam

Autor: Bill Arnsberg, George P. Naughton, Deborah Milks, Kirk Steinhorst, Mark Schuck

Publikováno v: Transactions of the American Fisheries Society. 139:1792-1801

Meeting escapement and recovery goals for Pacific salmon Oncorhynchus spp. is greatly facilitated by accurate and precise estimates of run size and stock composition. Although this is particularly important for endangered Pacific salmon runs like the

Water Velocity, Turbulence, and Migration Rate of Subyearling Fall Chinook Salmon in the Free-Flowing and Impounded Snake River

Autor: William P. Connor, Tobias J. Kock, R. Kirk Steinhorst, Craig A. Haskell, Kenneth F. Tiffan

Publikováno v: Transactions of the American Fisheries Society. 138:373-384

We studied the migratory behavior of subyearling fall Chinook salmon Oncorhynchus tshawytscha in free-flowing and impounded reaches of the Snake River to evaluate the hypothesis that velocity and turbulence are the primary causal mechanisms of downst

Using Bioenergetics Modeling to Estimate Consumption of Native Juvenile Salmonids by Nonnative Northern Pike in the Upper Flathead River System, Montana

Autor: Brian Marotz, Matthew C. Boyer, Clint C. Muhlfeld, R. Kirk Steinhorst, David H. Bennett

Publikováno v: North American Journal of Fisheries Management. 28:636-648

Introductions of nonnative northern pike Esox lucius have created recreational fisheries in many waters in the United States and Canada, yet many studies have shown that introduced northern pike may alter the composition and structure of fish communi

Two Alternative Juvenile Life History Types for Fall Chinook Salmon in the Snake River Basin

Autor: Kenneth F. Tiffan, Doug Ross, R. Kirk Steinhorst, John G. Sneva, William P. Connor

Publikováno v: Transactions of the American Fisheries Society. 134:291-304

Fall Chinook salmon Oncorhynchus tshawytscha in the Snake River basin were listed under the Endangered Species Act in 1992. At the time of listing, it was assumed that fall Chinook salmon juveniles in the Snake River basin adhered strictly to an ocea

Movement and Spawner Distribution of Hatchery Fall Chinook Salmon Adults Acclimated and Released as Yearlings at Three Locations in the Snake River Basin

Autor: William P. Connor, Aaron P. Garcia, R. Kirk Steinhorst, Deborah J. Milks, Stephen J. Rocklage

Publikováno v: North American Journal of Fisheries Management. 24:1134-1144

As part of the supplementation program for fall Chinook salmon Oncorhynchus tshawytscha in the Snake River basin, yearlings from Lyons Ferry Hatchery were released at acclimation facilities stationed along the lower Clearwater River and the lower and

Confidence intervals for fish out-migration estimates using stratified trap efficiency methods

Autor: Brian Dennis, Kirk Steinhorst, Yingqin Wu, Paul Kline

Publikováno v: Journal of Agricultural, Biological, and Environmental Statistics. 9:284-299

Marked fish placed above a smolt trap allow fisheries biologists to estimate the efficiency of the trap and hence to estimate the number of smolts migrating past the trap. We compared stratified maximum likelihood estimators and confidence intervals
