We summarized existing knowledge on behavioural and physiological responses of Okanagan sockeye salmon (O. nerka) adults to annual and seasonal variations in aquatic thermal regimes during migration. This enabled us to identify an underlying set of ’decision rules’ as a biophysical model of how temperature mediates en-route delays as a specific element of annual migrations by sockeye salmon. Several sets of results indicate that adult sockeye migrations stop as seasonal water temperatures… 

Influence of ocean and freshwater conditions on Columbia River sockeye salmon Oncorhynchus nerka adult return rates

Changes in ocean conditions in the northern California Current system, as captured by April upwelling and PNI, appeared to play a large role in the variability of SAR, and were primarily correlative and limited by the type and amount of data currently available.

The cumulative impacts of climate change on Fraser River sockeye salmon (Oncorhynchus nerka) and implications for management

Anadromous Pacific salmon (Oncorhynchus spp.) are vulnerable to climate change in both freshwater and marine habitats. I use a qualitative model to assess the cumulative effects of climate change

Snake River sockeye and Chinook salmon in a changing climate: Implications for upstream migration survival during recent extreme and future climates

Examination of factors affecting survival of endangered sockeye and threatened Chinook salmon as they migrated upstream through eight dams and reservoirs to spawning areas in the Snake River Basin found sockeye have likely lost much of their adaptive capacity with the loss of the wild population.

Challenges in the Identification and Interpretation of Phenological Shifts: Anthropogenic Influences on Adult Migration Timing in Salmonids

Overall, it is challenging to attribute causation to phenological change, but salmon exemplify the many ways in which migration timing can change, including shifts due to climate and other processes.

Migration and survival of Okanagan River Sockeye Salmon Oncorhynchus nerka, 2012–2019

Background Okanagan River Sockeye Salmon Oncorhynchus nerka (Okanagan Sockeye) are one of two remaining self-sustaining Sockeye Salmon populations in the Columbia River Basin. We used detection

Modeling the Influence of Environmental Factors on Spawning Migration Mortality for Sockeye Salmon Fisheries Management in the Fraser River, British Columbia

Abstract The impact of freshwater environmental factors on spawning migration mortality was modeled to provide a predictive tool for fisheries management of four run timing groups of Fraser River

Climate effects on growth, phenology, and survival of sockeye salmon (Oncorhynchus nerka): a synthesis of the current state of knowledge and future research directions

It is revealed that associations between temperature and growth, phenology, or survival have been uncovered for all the life stages of sockeye salmon, whereas relationships with other climate-related variables have been sparse.

Effect of water temperature, timing, physiological condition, and lake thermal refugia on migrating adult Weaver Creek sockeye salmon (Oncorhynchus nerka)

By using lakes as thermal refugia, early-timed fish likely reduce rates of disease development and may better recover from physiological stress associated with high encountered tempera- tures.

Pacific Salmon in Hot Water: Applying Aerobic Scope Models and Biotelemetry to Predict the Success of Spawning Migrations

It is suggested that collapse of aerobic scope was an important mechanism to explain the high salmon mortality observed during their migration and models based on thermal optima for aerobic scope for ectothermic animals should improve predictions of population fitness under future climate scenarios.

The impacts of climate change on the reproductive success of migratory fish

This review focuses on the specific locomotor responses of salmonids to thermal and hydrological challenges, identifying gaps in knowledge and highlighting the potential implications for key aspects of their reproduction.



Environmental Changes Affecting the Migratory Timing of American Shad and Sockeye Salmon

It is hypothesized that American shad and sockeye salmon may have evolved a migratory pattern that allows greater behavioral response to environmental fluctuations than sockeye Salmon, which spawn in distant lo- cations many months after their upriver migration.

A Habitat Based Evaluation of Okanagan Sockeye Salmon Escapement Objectives

Information from both historic and recent assessment activities has been assembled in this report to determine the current status of Okanagan sockeye. Subsets of the information are then used to: (i)

Temperature, flow, and the migration of adult sockeye salmon (Oncorhynchus nerka) in the Columbia River

The travel rate between McNary and Rock Island dams did not change from 1955 to 1994, despite a decrease in estimated water velocity from 85 to 23 km/day, and both travel rate and arrival date were correlated with temperature increases and flow decreases at McNary during that period.

Energetic Responses of Salmon to Temperature. A Study of Some Thermal Relations in the Physiology and Freshwater Ecology of Sockeye Salmon (Oncorhynchus nerkd)

It is concluded that a mechanism of behavioral thermoregulation has evolved which favorably balances daily metabolic expenditures in order to conserve energy when food is limited.

The effect of temperature on swimming performance and oxygen consumption in adult sockeye (Oncorhynchus nerka) and coho (O. kisutch) salmon stocks

It is concluded that high-caliber respirometry can be performed in a field setting and that stock-specific differences in swimming performance of adult salmon may be important for understanding upstream migration energetics and abilities.


Twelve salmonid evolutionarily significant units (ESUs) throughout the Columbia River Basin are currently listed as threatened or endangered under the Endangered Species Act; these ESUs are affected

Cycles in Ocean Productivity, Trends in Habitat Quality, and the Restoration of Salmon Runs in Oregon

Abstract Conservation management is always a political, as well as a biological, problem. Oregon's coastal natural coho salmon (Oncorhynchus kisutch) populations have drawn political attention

Analysis of Chinook Salmon in the Columbia River from an Ecosystem Perspective. Final Report.

Ecosystem Diagnosis and Treatment (EDT) methodology was applied to the analysis of chinook salmon in the mid-Columbia subbasins which flow through the steppe and steppe-shrub vegetation zones. The

Status of Anadromous Salmon and Trout in British Columbia and Yukon

Using fisheries agency databases and files, a summary database on the status of anadromous salmon stocks (genus Oncorhynchus) from British Columbia and Yukon streams is assembled and assessments found 624 stocks were at high risk, 78 were at moderate risk, 230 were of special concern, and 142 were extirpated in this century.
