Piscirickettsiosis in Farmed Turbot, Scophthalmus maximus

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsia salmonis is a well‐established intracellular pathogen of farmed Atlantic salmon around the world. The bacterium has also been detected from a number of other hosts including lumpfish (Cyclopterus lumpus), seabass (Dicentrarchus labrax) and rainbow trout (Oncorhynchus mykiss).

Detection of selection signatures in farmed coho salmon (Oncorhynchus kisutch) using dense genome-wide information

Scientific Reports, 2021
Animal domestication and artificial selection give rise to gradual changes at the genomic level in populations. Subsequent footprints of selection, known as selection signatures or selective sweeps, have been traced in the genomes of many animal ...

Why we age

Biological Reviews, Volume 101, Issue 2, Page 911-925, April 2026.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

Effect of dietary iron (Fe) supplementation on growth performance, hematological parameters and anti-oxidant responses of coho salmon Oncorhynchus kisutch (Walbaum, 1792) post-smolts

Aquaculture Reports
Effects of graded dietary iron (Fe) levels on coho salmon Oncorhynchus kisutch (Walbaum, 1792) post-smolts were assessed by determining the growth performance, Fe deposited in tissue, liver and serum antioxidant and immunity responses.

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.

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 ...

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 ...

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment

Fish and Fisheries, Volume 27, Issue 2, Page 160-178, March 2026.
ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.
