Community structure and range shifts in Arctic marine fish under climate change

Ecography, Volume 2026, Issue 1, January 2026.
Arctic marine ecosystems are rapidly transforming due to climate change. Warming temperatures and shrinking sea ice are enabling boreal fish to expand northward, possibly disturbing cold‐adapted Arctic species assemblages. Species range shifts have been documented in the Bering and Barents Seas, raising concerns about ecosystem restructuring.

A new method for the rapid detection of Atlantic cod (Gadus morhua), Pacific cod (Gadus macrocephalus), Alaska pollock (Gadus chalcogrammus) and ling (Molva molva) using a lateral flow dipstick assay

Food Chemistry, 2017
Species-specific lateral flow dipstick (LFD) assays for the identification of Atlantic cod (Gadus morhua), Pacific cod (Gadus macrocephalus), Alaska pollock (Gadus chalcogrammus) and ling (Molva molva) in food products were developed. The method comprises a PCR system with four sets of specific primers, for each target species.

Spatial and temporal changes in assemblage structure of zooplankton and pelagic fish in the eastern Bering Sea across varying climate conditions

Известия ТИНРО, 2015
Zooplankton and pelagic fish samples collected on the eastern Bering Sea shelf in late summer 2003-2010 were used to evaluate spatial and temporal changes in the plankton and nekton community structure.

Shifting stage‐specific constraints on productivity shape recovery potential for Yukon River Chinook salmon [PDF]

Ecol Appl
Abstract Identifying key life history periods in which population productivity is constrained represents a persistent challenge in conservation and natural resource management. For species with complex life cycles, such as Pacific salmon (Oncorhynchus spp.), population dynamics may be shaped by interactions between natural and anthropogenic impacts ...

Bottom‐Up Interactions in State‐Space Age‐Structured Models Using Mass‐Balance Dynamics

Fish and Fisheries, Volume 26, Issue 6, Page 1048-1064, November 2025.
ABSTRACT Age‐structured models are used worldwide to regulate fisheries. These models typically ignore top‐down interactions (predation affecting natural mortality) and bottom‐up interactions (consumption affecting individual growth, reproduction, or survival), whereas multispecies catch‐at‐age models often incorporate top‐down but not bottom‐up ...

Otolith radiocarbon signatures provide distinct migration history of walleye pollock around Hokkaido, Japan in the North‐Western Pacific

Ecology and Evolution
Trace elements and stable isotope ratios in otoliths have been used as proxies for the migration history of teleosts; however, their application in oceanic fishes remains limited.

Drivers and Dynamics of Salmon Bycatch in the Eastern Bering Sea Pollock Fishery

Fish and Fisheries, Volume 26, Issue 6, Page 1107-1121, November 2025.
ABSTRACT Minimising bycatch is a pervasive challenge for sustainable fisheries management, the importance of which is amplified for non‐target species or populations that are in decline. In the eastern Bering Sea (EBS) walleye pollock (Gadus chalcogrammus) fishery, salmon—most notably Chinook (Oncorhynchus tshawytscha) and chum (O.

Fluid preservation causes minimal reduction of parasite detectability in fish specimens: A new approach for reconstructing parasite communities of the past?

Ecology and Evolution, 2020
Long‐term datasets are needed to evaluate temporal patterns in wildlife disease burdens, but historical data on parasite abundance are extremely rare. For more than a century, natural history collections have been accumulating fluid‐preserved specimens ...

Assessment of heavy metal concentrations in imported marine fish species consumed in Ogun state, Nigeria

Aceh Journal of Animal Science
Fish is an affordable protein source in developing countries such as Nigeria, however, human activities like mining, agriculture, and industrial discharges negatively impact these aquatic resources and their environment. Heavy metals leach into the ocean

Using Vessel Monitoring System Data to Identify and Characterize Trips Made by Fishing Vessels in the United States North Pacific.

PLoS ONE, 2016
Time spent fishing is the effort metric often studied in fisheries but it may under-represent the effort actually expended by fishers. Entire fishing trips, from the time vessels leave port until they return, may prove more useful for examining trends in
