TLDR
The mean spawning dates of coho salmon Oncorhynchus kisutch and chinook salmon O. tshawytscha at the University of Washington Hatchery have become earlier over the period of record at the UW Hatchery, apparently because of selection in the hatchery.Abstract:
Spawning date is a crucial life history trait in fishes, linking parents to their offspring, and it is highly heritable in salmonid fishes. We examined the spawning dates of coho salmon Oncorhynchus kisutch and chinook salmon O. tshawytscha at the University of Washington (UW) Hatchery for trends over time. We then compared the spawning date patterns with the changing thermal regime of the Lake Washington basin and the spawning patterns of conspecifics at two nearby hatcheries. The mean spawning dates of both species have become earlier over the period of record at the UW Hatchery (since the 1950s for chinook salmon and the 1960s for coho salmon), apparently because of selection in the hatchery. Countering hatchery selection for earlier spawning are the increasingly warmer temperatures experienced by salmon migrating in freshwater to, and holding at, the hatchery. Spawning takes place even earlier at the Soos Creek Hatchery, the primary ancestral source of the UW populations, and at the Issaquah ...read more

A review of the likely effects of climate change on anadromous Atlantic salmon Salmo salar and brown trout Salmo trutta, with particular reference to water temperature and flow.
Bror Jonsson,Nina Jonsson +1 more
TL;DR: There is reason to expect a northward movement of the thermal niche of anadromous salmonids with decreased production and population extinction in the southern part of the distribution areas, migrations earlier in the season, later spawning, younger age at smolting and sexual maturity and increased disease susceptibility and mortality.

TL;DR: A conceptual model of how changing environmental conditions shift phenotypic optima and, through plastic responses, phenotype distributions, affecting the force of selection is presented.

TL;DR: The historical, political and scientific aspects of salmon hatchery programmes designed to enhance fishery production, or to recover endangered populations, are reviewed, and several approaches to studying the economic consequences of hatchery activities intended to inform the social decisions surrounding programmes are reviewed.

Life-history divergence in chinook salmon: historic contingency and parallel evolution
TL;DR: Genetic data indicate that in the interior Columbia Basin, the two divergent lineages behave essentially as separate biological species, showing little evidence of genetic contact in spite of the fact that they comigrate through large areas of the river and ocean and in some locations spawn in nearly adjacent areas.

TL;DR: The relationship between lower Columbia River water temperatures and migration rates, temporary tributary use, and run timing of adult fall Chinook salmon Oncorhynchus tshawytscha were studied using historical counts at dams and recently collected radiotelemetry data.

Selection against late emergence and small offspring in Atlantic salmon (Salmo salar).
Sigurd Einum,Ian A. Fleming +1 more
TL;DR: The hypothesis that selection on juvenile traits may play an important role in the evolution of maternal traits in natural populations is supported, and egg size had fitness consequences independent of the effects of emergence time that directly affected body size at emergence and, in turn, survival and size at later life stages.

Genetic interactions Between Hatchery and Wild Salmonids: Lessons from the Pacific Northwest
TL;DR: The potential for genetic interactions between hatchery and wild populations of salmonids in northwestern North America has increased considerably in recent decades, and efforts to mitigate severe losses to many wild stocks caused by overfishing, destruction of habitat, and blockage of migratory routes have focussed on boosting artificial production in public hatcheries.

Environmental Changes Affecting the Migratory Timing of American Shad and Sockeye Salmon
Thomas P. Quinn,Dean J. Adams +1 more
TL;DR: 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.
