Parvicapsula pseudobranchicola in the northeast Pacific Ocean is rare in farmed Atlantic salmon Salmo salar despite widespread occurrence and pathology in wild Pacific salmon Oncorhynchus spp.

Parasites & Vectors, 2023
Background Infection with the myxozoan parasite Parvicapsula pseudobranchicola causes disease in wild and farmed salmonids in Norway. In the northeast Pacific Ocean, the parasite has been reported in Pacific salmon Oncorhynchus spp.

Olfactory Imprinting of Amino Acids in Lacustrine Sockeye Salmon

PLoS ONE, 2010
Juvenile salmon have an olfactory ability to imprint their natal stream odors, but neither the odor properties of natal stream water nor the imprinting timing and duration have been clarified as yet. Here we show, using electrophysiological and behavioral experiments, that one-year-old lacustrine sockeye salmon (Oncorhynchus nerka) can be imprinted ...

Understanding Smolt Survival Trends in Sockeye Salmon [PDF]

Marine and Coastal Fisheries, 2013
Abstract Many populations of Sockeye Salmon Oncorhynchus nerka in the eastern North Pacific Ocean experienced significant productivity declines that began about 1990, but there is no consensus on the mechanisms responsible. To better understand Sockeye Salmon survival trends, we examined the 50-year time series for two age-classes of ...

Trends in Aquatic Environmental DNA Research in Alaska

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Environmental DNA (eDNA) analysis is an emerging tool with significant potential to advance biomonitoring, particularly in remote and logistically challenging environments. To evaluate the state of eDNA research in Alaska, we conducted a literature review and a regional survey and results provide the first comprehensive overview of eDNA research in ...

Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, Volume 42, Issue 6, Page 1172-1187, July 2026.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

The Forgotten Pink Salmon in the Laurentian Great Lakes: An Unexpected Invasion With Insights for Three Oceans

Fish and Fisheries, Volume 27, Issue 4, Page 813-830, July 2026.
ABSTRACT Introductions of species outside their native range, such as pink salmon (Oncorhynchus gorbuscha) in the Laurentian Great Lakes, can serve as unplanned experiments that provide new insights into ecological adaptation. We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform
