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

California 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

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 ...

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 ...

How riparian and floodplain restoration modify the effects of increasing temperature on adult salmon spawner abundance in the Chehalis River, WA

PLoS ONE, 2022
Stream temperatures in the Pacific Northwest are projected to increase with climate change, placing additional stress on cold-water salmonids. We modeled the potential impact of increased stream temperatures on four anadromous salmonid populations in the

Shedding Kinetics of Infectious Hematopoietic Necrosis Virus (IHNV) in Juvenile Spring- and Fall-Run Chinook Salmon of the Columbia River Basin

Animals, 2022
This investigation sought to characterize the shedding of infectious hematopoietic necrosis virus (IHNV) in two populations of Columbia River Basin (CRB) Chinook salmon (Oncorhynchus tshawytscha). Juvenile spring- and fall-run Chinook salmon were exposed

Chinook and Coho salmon hybrids linked to habitat and climatic changes on Vancouver Island, British Columbia

Ecology and Evolution, 2021
Between 2013 and 2019, 63 presumed Chinook salmon Oncorhynchus tshawytscha sampled primarily in the Strait of Georgia (0.63% of total sample) were identified as potential Chinook–Coho (Oncorhynchus kisutch) hybrids by the presence of anomalous ...

Parentage‐based tagging combined with genetic stock identification is a cost‐effective and viable replacement for coded‐wire tagging in large‐scale assessments of marine Chinook salmon fisheries in British Columbia, Canada

Evolutionary Applications, 2021
Wild Pacific salmon, including Chinook salmon Oncorhynchus tshawytscha, have been supplemented with hatchery propagation for over 50 years in support of increased ocean harvest, mitigation for hydroelectric development, and conservation of threatened ...
