Density‐dependent marine survival of hatchery‐origin Chinook salmon may be associated with pink salmon

Ecosphere, 2020
Understanding how protected species influence the population dynamics of each other is an essential part of ecosystem‐based management. Chinook salmon (Oncorhynchus tshawytscha) are critical prey for endangered southern resident killer whales (SRKWs ...

Partitioning the influence of Chinook salmon productivity and stock-specific abundance on the southern resident killer whale population

Global Ecology and Conservation
The southern resident killer whale (Orcinus orca, SRKW) population is listed as endangered in both the U.S. and Canada. Reduced prey availability, especially of Chinook salmon, is recognized as an important limiting factor for this population.

Chinook salmon depth distributions on the continental shelf are shaped by interactions between location, season, and individual condition [PDF]

Movement Ecology
Background Ecological and physical conditions vary with depth in aquatic ecosystems, resulting in gradients of habitat suitability. Although variation in vertical distributions among individuals provides evidence of habitat selection, it has been ...

Biotransport of persistent organic pollutants in the southern Hemisphere by invasive Chinook salmon (Oncorhynchus tshawytscha) in the rivers of northern Chilean Patagonia, a UNESCO biosphere reserve

Environment International, 2020
Biotransport is often associated with migration patterns of species, including large, anadromous salmonids. Several studies have reported biotransport of persistent organic pollutants in the Northern Hemisphere, but there is no published information on ...

Acute Toxicity of 6PPD‐Quinone to Early Life Stage Juvenile Chinook (Oncorhynchus tshawytscha) and Coho (Oncorhynchus kisutch) Salmon

Environmental Toxicology and Chemistry, 2023
The breakdown product of the rubber tire antioxidant N‐(1,3‐dimethylbutyl)‐N'‐phenyl‐p‐phenylenediamine‐quinone (6PPD)‐6‐PPD‐quinone has been strongly implicated in toxic injury and death in coho salmon (Oncorhynchus kisutch) in urban waterways.

Climate change threatens Chinook salmon throughout their life cycle

Communications Biology, 2021
Widespread declines in Atlantic and Pacific salmon (Salmo salar and Oncorhynchus spp.) have tracked recent climate changes, but managers still lack quantitative projections of the viability of any individual population in response to future climate ...

Requirements and availability of prey for northeastern pacific southern resident killer whales

PLoS ONE, 2022
The salmon-eating Southern Resident killer whale (SRKW) (Orcinus orca) population currently comprises only 73 individuals, and is listed as ‘endangered’ under the Species at Risk Act in Canada.

Color photographic index of fall Chinook salmon embryonic development and accumulated thermal units. [PDF]

PLoS ONE, 2010
BACKGROUND: Knowledge of the relationship between accumulated thermal units and developmental stages of Chinook salmon embryos can be used to determine the approximate date of egg fertilization in natural redds, thus providing insight into oviposition ...
