Fisheries Management and Ecology, Volume 33, Issue 5, Page 879-893, October 2026.ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...

Parasites & Vectors, 2023 Background Infection with the myxozoan parasite Parvicapsula pseudobranchicola causes disease in wild and farmed salmonids in Norway. In the northeast Pacific Ocean, the parasite has been reported in Pacific salmon Oncorhynchus spp.

Ecology and Evolution, Volume 16, Issue 9, September 2026.We have examined the phylogenetic relationships, genomic structure, admixture, and historical gene flow among the endemic charrs from the Kronotskoe‐Uzon water system in Kamchatka, in order to reconstruct their evolutionary history. We found that this unique diversity formed in the post‐LGM—Holocene time as a result of several waves of Salvelinus malma

A metabolic life table exemplified by sockeye salmon [PDF]
, 2020 Abstract A metabolic life table (MLT) is a combination of energy budget and life table that quantifies metabolism and life history over an entire life cycle. It provides a conceptual framework for integrating data on physiology, demography and ecology that are usually the ...

Известия ТИНРО, 2020 Aerial survey of the pacific salmon spawning grounds was conducted in the water bodies of Chukotka belonged to the Bering Sea basin (the Anadyr, Velikaya, Tumanskaya Rivers and Meinypilgyno lake-river system) in 2019, for the first time since 1992. Total

High and minimally variable adult marine survival among multiple stocks of Chinook salmon
Ecosphere, Volume 17, Issue 9, September 2026.Abstract Estimates of individual survival across space and time provide critical information on processes that regulate population abundance. Here, we use state‐space models fit to data from more than 500 acoustically tagged Chinook salmon to better understand the factors that shape survival during the final summer and fall of marine residence—a life ...

Olfactory Imprinting of Amino Acids in Lacustrine Sockeye Salmon
PLoS ONE, 2010 Juvenile salmon have an olfactory ability to imprint their natal stream odors, but neither the odor properties of natal stream water nor the imprinting timing and duration have been clarified as yet. Here we show, using electrophysiological and behavioral experiments, that one-year-old lacustrine sockeye salmon (Oncorhynchus nerka) can be imprinted ...

Understanding Smolt Survival Trends in Sockeye Salmon [PDF]
Marine and Coastal Fisheries, 2013 Abstract Many populations of Sockeye Salmon Oncorhynchus nerka in the eastern North Pacific Ocean experienced significant productivity declines that began about 1990, but there is no consensus on the mechanisms responsible. To better understand Sockeye Salmon survival trends, we examined the 50-year time series for two age-classes of ...

Ecology, Volume 107, Issue 9, September 2026.Abstract Scavengers play a key role in recycling animal biomass, yet the relative contributions of insects and vertebrates to this process remain poorly understood. Moreover, understanding whether one scavenger group can compensate for the absence of another is critical for predicting how carrion decomposition may respond to changes in community ...
