Chinook salmon (Oncorhynchus tshawytscha) genome and transcriptome. [PDF]

PLoS ONE, 2018
When unifying genomic resources among studies and comparing data between species, there is often no better resource than a genome sequence. Having a reference genome for the Chinook salmon (Oncorhynchus tshawytscha) will enable the extensive genomic ...

Mixed-maturation fisheries compromise productivity and resilience of Chinook salmon [PDF]

Scientific Reports
Most ocean-type Chinook salmon (Oncorhynchus tshawytscha) in the northeast Pacific Ocean are harvested in mixed-stock marine fisheries. Here, multiple populations with varying abundance and productivities are encountered. In addition to being mixed-stock,

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 ...

Swimming behavior of emigrating Chinook Salmon smolts. [PDF]

PLoS One, 2022
Swimming behavior of Chinook Salmon (Oncorhynchus tshawytscha) smolts affects transit time, route selection and survival in complex aquatic ecosystems. Behavior quantified at the river reach and junction scale is of particular importance for route selection and predator avoidance, though few studies have developed field-based approaches for quantifying

Steller sea lion (Eumetopias jubatus) consumption of ocean age-0 Chinook salmon (Oncorhynchus tshawytscha) along the northwest coast of Washington State. [PDF]

PLoS ONE
The decline of wild Chinook salmon (Oncorhynchus tshawytscha) in the Pacific Northwest is concerning due to their critical role in the culture, economy, and ecology of the region, and the endangered species status of some of the evolutionarily ...

Subyearling Chinook salmon diets in Lower Columbia River estuarine habitats. [PDF]

PLoS ONE
The Lower Columbia River and Estuary is critical rearing habitat for juvenile Pacific salmon. Extending from the river mouth to Bonneville Dam 235 river kilometers upstream, the Estuary has been altered by dams, dikes, and habitat loss due to ...

Characterising the Physiological Responses of Chinook Salmon (Oncorhynchus tshawytscha) Subjected to Heat and Oxygen Stress [PDF]

Biology, 2023
In New Zealand, during the hottest periods of the year, some salmon farms in the Marlborough Sounds reach water temperatures above the optimal range for Chinook salmon.

A single generation in the wild increases fitness for descendants of hatchery‐origin Chinook salmon (Oncorhynchus tshawytscha) [PDF]

Evolutionary Applications
Reintroduction is an important tool for the recovery of imperiled species. For threatened Pacific salmonids (Oncorhynchus spp.) species, hatchery‐origin (HOR) individuals from a nearby source are often used to reestablish populations in vacant ...

Heritability and genomic basis of age-at-maturity in Chinook Salmon. [PDF]

J Hered
Abstract Intrapopulation variation in the age at return and reproduction of Chinook Salmon (Oncorhynchus tshawytscha), or age-at-maturity, acts as a buffer against stochastic environmental variation. We investigated the genetic component of this trait by estimating the heritability of age-at-maturity and the genomic basis of both sex and

Genomics and 20 years of sampling reveal phenotypic differences between subpopulations of outmigrating Central Valley Chinook salmon [PDF]

Evolutionary Applications
Intraspecific diversity plays a critical role in the resilience of Chinook salmon populations. California's Central Valley (CV) historically hosted one of the most diverse population complexes of Chinook salmon in the world.
