Sequencing improves our ability to study threatened migratory species: Genetic population assignment in California's Central Valley Chinook salmon

open access: yesEcology and Evolution, 2016
Effective conservation and management of migratory species requires accurate identification of unique populations, even as they mix along their migratory corridors. While telemetry has historically been used to study migratory animal movement and habitat

Effects of cover and mesohabitat type on the abundance of young-of-the-year Chinook salmon

open access: yesCalifornia Fish and Wildlife Journal
Snorkel surveys were conducted on the Sacramento River to investigate the relative importance of microhabitat and mesohabitat scales on the abundance of young of the year (YOY) Chinook salmon (Oncorhynchus tshawytscha), while taking into account temporal

Initial responses of Chinook salmon (Oncorhynchus tshawytscha) and steelhead (Oncorhynchus mykiss) to removal of two dams on the Elwha River, Washington State, U.S.A.

open access: yesFrontiers in Ecology and Evolution
Large dam removal is being used to restore river systems, but questions remain regarding their outcomes. We examine how the removal of two large dams in the Elwha River, coupled with hatchery production and fishing closures, affected population ...

The geographic basis for population structure in Fraser River chinook salmon (Oncorhynchus tshawytscha) [PDF]

open access: yes, 2003
We surveyed variation at 13 microsatellite loci in approximately 7400 chinook salmon sampled from 52 spawning sites in the Fraser River drainage during 1988–98 to examine the spatial and temporal basis of population structure in the watershed ...

Ecological implications of changing hatchery practices for Chinook salmon in the Salish Sea

open access: yesEcosphere, 2019
For over a century, hatchery programs have been used to subsidize natural salmon populations in order to increase fisheries opportunities and, more recently, to conserve declining natural populations.
