Seasonal presence, movements and behaviour of Atlantic cod (Gadus morhua) in Isfjorden, Svalbard
Journal of Fish Biology, EarlyView.Abstract Atlantification is increasing the inflow of warm, salty Atlantic water into the Arctic region. The fjords on the western coast of Svalbard are experiencing Atlantification, enabling boreal species, such as Atlantic cod (Gadus morhua), to expand their distribution northwards.

Embryonic Crude Oil Exposure Impairs Growth and Lipid Allocation in a Keystone Arctic Forage Fish
iScience, 2019 Summary: As Arctic ice recedes, future oil spills pose increasing risk to keystone species and the ecosystems they support. We show that Polar cod (Boreogadus saida), an energy-rich forage fish for marine mammals, seabirds, and other fish, are highly ...

Journal of Fish Biology, Volume 109, Issue 4, Page 2204-2209, October 2026.Abstract Biofluorescence is widespread among marine fish but remains poorly documented in polar ecosystems. Using hyperspectral imaging, we report fluorescent emissions in two polar zoarcid eelpouts. A captive Antarctic eelpout (Pachycara brachycephalum) displayed uniform bright green fluorescence (~500–520 nm), whereas an Arctic eelpout (Lycodes ...

Linking the Movement Behavior of the Laptev Sea Walrus to Sea Ice and Resource Dynamics
Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT The walrus subspecies inhabiting the Laptev Sea (Odobenus rosmarus divergens) remains one of the least studied walrus taxa and occurs in a region undergoing rapid environmental change driven by climate warming and increasing human activity. We conducted the first satellite telemetry study of walruses in this region, tracking 14 individuals ...

Fish and Fisheries, Volume 27, Issue 5, Page 1176-1192, September 2026.ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.

Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters
Global Change Biology, Volume 32, Issue 8, August 2026.Polar sharks, rays, and chimaeras face growing pressures from changing sea‐ice conditions, expanding fisheries, and limited protection. Our assessment highlights where critical habitats occur and how Important Shark and Ray Areas (ISRAs) can support more targeted conservation and fisheries management across the Arctic and Antarctic.
