Cost‐Effective Quantitative PCR Assays for the eDNA‐Based Detection of Three Sympatric Salmon Species

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
We developed species‐specific dye‐based qPCR assays for three sympatric Northeast Asian salmonids (Oncorhynchus keta, O. masou, O. gorbuscha). After validating primer specificity, we used field eDNA to map their spatiotemporal distributions, offering cost‐effective, reliable tools for salmon conservation management.

Prey group cohesion mediates the outcome of predator–prey interactions under artificial lighting

Functional Ecology, Volume 40, Issue 9, Page 2818-2829, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The highest rates of piscivorous predation in the field have been recorded during crepuscular light levels associated with sunrise and sunset or artificial lighting at night (ALAN).

Contrasting Patterns of Genetic Isolation Among Diadromous, Landlocked, and Non‐Migratory Gobiid Fish Populations

Molecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT Dams can landlock populations of amphidromous fishes that formerly migrated between rivers and seas. However, the genetic consequences of these life‐cycle changes remain unclear. Rhinogobius is a speciose genus of freshwater gobies widely distributed in Asia, including non‐migratory R. duospilus and facultatively amphidromous R. similis. Using

Oncorhynchus nerka population monitoring in the Sawtooth Valley Lakes

, 1996
Critical habitat for endangered Snake River sockeye salmon includes five rearing lakes located in the Sawtooth Valley of central Idaho. Most of the lakes contain either introduced or endemic kokanee populations. Snake River sockeye occur naturally in Redfish Lake, and are being stocked in Redfish and Pettit Lakes.

Study of single nucleotide polymorphism DNA in populations of sockeye salmon at Kamchatka, northwestern coast of the Okhotsk Sea, and Chukotka

Известия ТИНРО, 2017
Population structure of Asian sockeye salmon is considered by variability of 45 loci of single nucleotide polymorphism DNA (SNP) in 17 samples from its 10 major spawning grounds at Chukotka, Kamchatka, and northwestern coast of the Okhotsk Sea.

Brain aging phenomena in migrating sockeye salmon Oncorhynchus nerka nerka

, 2018
Aging, a process occuring in all vertebrates, is closely related to a loss in physical and functional abilities. There is widespread interest in clarifying the relevance of environmental, metabolic, and genetic factors for vertebrate aging. In the Pacific salmon a dramatic example of aging is known. Looking for changes in the salmon brain, perhaps even

Delineating population structure of resilient sea/river‐type sockeye salmon

Limnology and Oceanography Letters
Conserving wild fisheries requires identifying and monitoring distinct populations, yet prevalent genetic approaches often do not integrate habitat data and may not fully delineate these structures. This issue is critical in sea/river‐type sockeye salmon
