Climate vulnerability assessment for Pacific salmon and steelhead in the California Current Large Marine Ecosystem. [PDF]

, 2019
Major ecological realignments are already occurring in response to climate change. To be successful, conservation strategies now need to account for geographical patterns in traits sensitive to climate change, as well as climate threats to species-level ...

Evolution of age and length at maturation of Alaskan salmon under size-selective harvest [PDF]

, 2013
Spatial and temporal trends and variation in life-history traits, including age and length at maturation, can be influenced by environmental and anthropogenic processes, including size-selective exploitation.

Freshwater feeding by adult chum salmon Oncorhynchus keta in the Mackenzie River, Northwest Territories

Frontiers in Ecology and Evolution
As distributional shifts of marine species into the Arctic become more frequent, these range-expanding individuals may exhibit unique traits that facilitate survival and establishment in new places.

Determination of population structure and stock composition of chum salmon (Oncorhynchus keta) in Russia determined with microsatellites [PDF]

, 2008
Variation at 14 microsatellite loci was examined in 34 chum salmon (Oncorhynchus keta) populations from Russia and evaluated for its use in the determination of population structure and stock composition in simulated mixed-stock fishery samples.

Landscape Structure and Species Interactions Drive the Distribution of Salmon Carcasses in Coastal Watersheds

Frontiers in Ecology and Evolution, 2019
The disproportionate effects of some species can drive ecosystem processes and shape communities. This study investigates how distributions of spawning Pacific salmon within streams, salmon consumers, and the surrounding landscape mediate the ...

Effects of starvation on energy density of juvenile chum salmon (Oncorhynchus keta) captured in marine waters of Southeastern Alaska [PDF]

, 2010
We conducted laboratory starvation experiments on juvenile chum salmon (Oncorhynchus keta) captured in the neritic marine waters of northern Southeast Alaska in June and July 2003. Temporal changes in fish energy density (whole body energy content [WBEC]

Characteristics of adult chum salmon Oncorhynchus keta from the commercial stock at Iturup Island in 2024

Известия ТИНРО
Spawners of chum salmon Oncorhynchus keta were examined in the basins of Prostor and Kurilsky Bays (Iturup Island, Kuril Islands) from September 23 to November 2, 2024. The portion of females naturally increased during the spawning run and was 43.3 %, on

Population structure of chum salmon (Oncorhynchus keta) across the Pacific Rim, determined from microsatellite analysis [PDF]

, 2009
The Pacific Rim population structure of chum salmon (Oncorhynchus keta) was examined with a survey of microsatellite variation to describe the distribution of genetic variation and to evaluate whether chum salmon may have originated from two or more ...

Feeding ecology of juvenile Pacific salmon (Oncorhynchus spp.) in a northeast Pacific fjord: diet, availability of zooplankton, selectivity for prey, and potential competition for prey resources [PDF]

, 2010
We investigated the feeding ecology of juvenile salmon during the critical early life-history stage of transition from shallow to deep marine waters by sampling two stations (190 m and 60 m deep) in a northeast Pacific fjord (Dabob Bay, WA) between May ...
