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.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Effects of Ichythyophonus on Chinook Salmon Reproductive Success in the Yukon River Draining [PDF]

, 2012
Ichthyophonus hoferi is a parasitic protozoan affecting marine and anadromous fishes, including salmonids (Kocan et al. 2004). Gross clinical signs associated with Ichthyophonus infection are multifocal white lesions on the heart, liver, spleen, and ...

Viral Disease Histopathology in Aquaculture Finfish: Organ‐Specific Pathological Changes and Diagnostic Insights, Referencing the World Organisation for Animal Health: A Review

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT The aquaculture industry faces significant challenges from viral diseases, many of which are listed by the World Organisation for Animal Health (WOAH) as priority pathogens due to their impact on global finfish health and production. This review synthesizes current knowledge on the histopathology of key WOAH‐listed viral pathogens, including ...

AmpliRAD: A New Method Combining Amplicon and RAD Sequencing

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We present AmpliRAD, a novel sequencing method that integrates a multiplex PCR step into traditional RAD‐seq protocols to enable the simultaneous generation of genome‐wide SNP data and targeted genotypes for specific loci. By appending restriction sites to target amplicons, the method overcomes the inability of standard RAD‐seq approaches to assay loci

Identifying Key Biodiversity Areas Based on Distinct Genetic Diversity

Molecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity. Distinct genetic diversity has been introduced as one of the metrics to estimate whether a site holds a threshold proportion of a species' global genetic diversity during the KBA identification process.

Legacy habitat contamination as a limiting factor for Chinook salmon recovery in the Willamette Basin, Oregon, USA.

PLoS ONE, 2019
In the western United States, the long-term recovery of many Pacific salmon populations is inextricably linked to freshwater habitat quality. Industrial activities from the past century have left a legacy of pollutants that persist, particularly near ...

Domestication‐Admixed Atlantic Salmon (Salmo salar) Establish a Productive Population in the Wild

Ecology Letters, Volume 29, Issue 2, February 2026.
We document colonisation of a river by highly (average 37%) domestication‐admixed salmon using genomic and phenotypic data. The resulting population now displays freshwater and marine productivity within ranges observed in wild populations. Our data demonstrate that domestication‐admixed individuals can rapidly establish populations in the wild, likely
