Health of Wild Atlantic Salmon (Salmo salar) Smolts Along Coastal Migratory Routes in Newfoundland, Canada With and Without Salmonid Aquaculture as Assessed Using Sentinel Cages

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Declines in wild Atlantic salmon populations in the North Atlantic with migratory routes adjacent to commercial salmonid aquaculture operations in coastal marine environments have raised concerns about the potential for direct or indirect effects this industry may have on local wild populations.

No Groundwater, No Fish: The Critical Role of Groundwater in Supporting Non‐Glacial, Salmon‐Bearing Rivers in South‐Central Alaska

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Groundwater discharge plays an important role in the hydrologic and ecologic functioning of rivers including sustaining streamflow and related habitat year‐round. Simultaneously, groundwater supports the increasing demands of people as the global population continues to grow.

Genetic Considerations for Sourcing Steelhead Reintroductions: Investigating Possibilities for the San Joaquin River

San Francisco Estuary and Watershed Science, 2014
Steelhead trout (Oncorhynchus mykiss) historically occurred in all major watersheds along the west coast of the United States. They can be a vital part of a healthy riverine ecosystem, are highly valued for fishing, and have been greatly affected by ...

Planning, Implementing, and Evaluating Stage 0 and Valley Bottom Restoration Projects: A Review With Lessons From the Grande Ronde Basin, USA

WIREs Water, Volume 13, Issue 2, March/April 2026.
Successful valley bottom restoration requires an understanding of current and historical conditions determining whether a reach can currently support a multi‐thread or meandering channel, an understanding of reference conditions to assist with design, clear objectives to evaluate design alternatives, and post‐project monitoring of success using a ...

Early life exploration behaviour and life‐history loci are colocalized in an adaptive genomic hotspot in Atlantic salmon

Journal of Animal Ecology, Volume 95, Issue 3, Page 418-429, March 2026.
The genetic architecture of phenotypic correlations offers insights into how natural selection operates in the wild. Two functional phenotypes in Atlantic salmon, early life exploration and age‐at‐maturity, are correlated at an adaptive genomic hotspot, but through distinct genetic markers (SNPs), ruling out causality.

Historic and Present Distribution of Chinook Salmon and Steelhead in the Calaveras River

San Francisco Estuary and Watershed Science, 2007
Interest is great in projects that would restore Central Valley steelhead (Oncorhynchus mykiss) and Central Valley Chinook salmon (Oncorhynchus tshawytscha) to California drainages where they have historically existed and where there is good quality ...

Variation in the early marine survival and behavior of natural and hatchery-reared Hood Canal steelhead. [PDF]

PLoS ONE, 2012
BACKGROUND: Hatchery-induced selection and direct effects of the culture environment can both cause captively bred fish populations to survive at low rates and behave unnaturally in the wild. New approaches to fish rearing in conservation hatcheries seek

Epigenetics in Captivity: Restoring Wild Phenotypes in Captive‐Reared Salmonids

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Captive rearing is a common practice for the stocking, conservation, and supplementation of fish species worldwide, but captive‐reared fish can exhibit altered phenotypes leading to reduced fitness in nature compared to wild conspecifics. In salmonids, certain studies have found limited genetic differentiation between wild and captive‐reared ...
