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.

The performance of model-based indices given alternative sampling strategies in a climate-adaptive survey design

Frontiers in Marine Science, 2023
Species-distribution shifts are becoming commonplace due to climate-driven change. Difficult decisions to modify survey extent and frequency are often made due to this change and constraining survey budgets.

Fishery and conservation implications of molecular characterization and traceability of ceviche samples from Pacific Panama

Marine and Fishery Sciences, 2023
Genetic analysis of 111 samples from ceviche cocktails and fish fillets used for ceviche, obtained from fish markets and processing plants in the Pacific zone of Panama were conducted to determine species composition, trace origin (native, nonnative or ...

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.

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 ...

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.

Practical Application of a Bioenergetic Model to Inform Management of a Declining Fur Seal Population and Their Commercially Important Prey

Frontiers in Marine Science, 2020
Food availability is a key concern for the conservation of marine top predators, particularly during a time when they face a rapidly changing environment and continued pressure from commercial fishing activities.

Biological and Physical Environmental Drivers of Diet Variation in Northern Fur Seals

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Interannual variation in northern fur seal diet composition was influenced by physical and biological variables within local foraging areas in the eastern Bering Sea. Our findings indicate that projected environmental changes in the eastern Bering Sea are likely to affect fur seal diet composition and potentially increase trophic pressure on non ...

Current Marine Protected Areas Conserve Fish Spawning Aggregations Under Climate Change due to Habitat Refugia

Global Change Biology, Volume 31, Issue 8, August 2025.
Nassau grouper, a tropical and endangered reef fish in the Caribbean, has narrower environmental tolerances during spawning than other life history periods. This research suggests that habitat suitable for spawning will decline due to climate change in the future. This is expected to occur inside and outside of areas with current management strategies,
