Beyond lethal temperatures: Factors behind the disappearance of chum salmon from their southern margins under climate change. [PDF]
PLoS ONEThe Tone River in Japan represents one of the southern limit distributions of chum salmon (Oncorhynchus keta) on the western side of the North Pacific, but the number of adult chum salmon observed here has declined dramatically since 2013 and reached ...

Climate-driven shifts in marine habitat explain recent declines of Japanese Chum salmon [PDF]
Scientific ReportsClimate change is accelerating at unprecedented rates, with disproportionate impacts on marine ecosystems. We examined the distributional responses of chum salmon (Oncorhynchus keta), a keystone species, to the recent climatic changes in the North ...

Spatiotemporal distribution of juvenile chum salmon in Otsuchi Bay, Iwate, Japan, inferred from environmental DNA. [PDF]
PLoS ONE, 2019 To understand the ecology of juvenile chum salmon during early marine life after their downstream migration, we developed a quantitative PCR-based environmental DNA (eDNA) method specific for chum salmon and investigated the spatiotemporal distribution ...

Regional-Scale Declines in Productivity of Pink and Chum Salmon Stocks in Western North America. [PDF]
PLoS ONE, 2016 Sockeye salmon (Oncorhynchus nerka) stocks throughout the southern part of their North American range have experienced declines in productivity over the past two decades. In this study, we tested the hypothesis that pink (O. gorbuscha) and chum (O. keta)

Genetic assessment of a summer chum salmon metapopulation in recovery. [PDF]
Evol Appl, 2014 AbstractPrograms to rebuild imperiled wild fish populations often include hatchery‐born fish derived from wild populations to supplement natural spawner abundance. These programs require monitoring to determine their demographic, biological, and genetic effects.

Jellyfish in Pacific salmon food
Известия ТИНРО, 2022 Ctenophores, hydroid jellyfish, appendicularians, salpas, and the pteropoda mollusk Clione limacina, conditionally combined into the group of “jellyfish”, are found in the food of all Pacific salmon — chum salmon, pink salmon, sockeye salmon, coho salmon
