Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

Olfactory inhibition and recovery in chum salmon (Oncorhynchus keta) following copper exposure [PDF]

open access: yes, 2006
Copper can be an effective hatchery treatment to control certain parasitic and fungal infections in salmonids, yet it is also highly toxic to the fish's olfactory system.

PENERAPAN METODE AIR BLAST FREEZING (ABF) PADA PEMBEKUAN IKAN SALMON CHUM (Oncorhynchus keta) DI PT. MARINE CIPTA AGUNG, PASURUAN, JAWA TIMUR [PDF]

open access: yes, 2016
Ikan Salmon mengandung protein kualitas tinggi dan omega 3 yang dapat menurunkan kolesterol serta meningkatkan kerja otak. Ikan Salmon tidak ada di perairan Indonesia, tetapi ikan-ikan tersebut diimpor dari negara produsen, kemudian diolah kembali ...

Freshwater hydrology emerges as the strongest predictor of phenological variability in a Southeast Alaska steelhead trout (Oncorhynchus mykiss) population

open access: yesJournal of Fish Biology, EarlyView.
Abstract Phenological variation, such as the migration trends of salmonids, may provide resilience in changing environmental scenarios, influencing individual survival and population productivity. Phenological shifts may be particularly consequential for anadromous species that rely on seasonal cues for migration between freshwater and marine habitats ...

Behavioral Ecology of Chum Salmon Fry (Oncorhynchus keta) in a Small Estuary

open access: yes, 1974
Chum salmon fry (Oncorhynchus keta) in the estuary of a small coastal stream exploited fresh water, estuarine, and marine food chains and, by so doing, were exposed to marked, daily fluctuations in salinity that demanded active selection of fresh water ...

UDN-like lesions of pacific salmon in Kamchatka

open access: yesИзвестия ТИНРО
The first documented cases of the ulcerative dermal necrosis (UDN) lesions are described for pacific salmon (pink salmon Oncorhynchus gorbuscha and chum salmon O. keta) in the waters of Kamchatka.

Dependence of progeny abundance for fall chum salmon ( Oncorhynchys keta) in the Amur River on the parents abundance

open access: yesИзвестия ТИНРО, 2015
The stock of the Amur fall chum salmon ( Oncorhynchys keta ) was low in 2000-2005 (annual catches varied in the range of 500-1300 t) but began to increase since 2006 and the catch exceeded 22000 t in 2014.

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

open access: yesEnvironmental 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.

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

open access: yesFisheries Oceanography, Volume 35, Issue 5, Page 689-703, September 2026.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Orientation of Chum Salmon (Oncorhynchus keta) After Internal and External Magnetic Field Alteration

open access: yes, 1983
Groups of hatchery reared juvenile chum salmon (Oncorhynchus keta) from Conuma River, British Columbia, were tested for compass directional preferences in experimental tanks. Chum salmon generally moved in the direction appropriate for migration through
