Acknowledgements
Thanks to Stephanie Quinn-Davidson and Holly Carroll for their
assistance and comradery on the Koyukuk. Fred West kindly provided
historical escapement estimates, and Jim Winton was instrumental in
pointing me to literature and educating me on all things columnaris.
Marta Ulaski aided with comparisons of selection to the global database.
Holly Carroll, Fred West, Zach Liller, and Jim Winton substantially
improved the manuscript based on their comments. I, along with all
Alaskans, are deeply indebted to the residents of the region that have
been and continue to be stewards of the river. Funding for the survey
was provided by the Yukon River Inter-tribal Fisheries Commission.
