The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.Finite mixture models revealed that older, larger harbor seals specialize in salmon predation at setnets in Hokkaido, Japan, suggesting targeted management strategies focusing on these specialist individuals could effectively reduce fishery conflicts while protecting the broader seal population.

Frontiers in Marine Science, 2020 In 2014–2016 an unprecedented warming event in the North Pacific Ocean triggered changes in ecosystem of the Gulf of Alaska (GOA) impacting fisheries management. The marine heatwave was noteworthy in its geographical extent, depth range, and persistence,

A histopathologic evaluation of gross lesions excised from commercially important North Altantic marine fishes [PDF]
, 1986 Histopathologic studies of lesions found in commercially important North Atlantic marine fishes are uncommon. As part of a comprehensive Northeast Fisheries Center program ("Ocean Pulse") to evaluate environmental and resource health on the U.S ...

Secondary sexual characteristics in codfishes (Gadidae) in relation to sound production, habitat use, and social behaviour [PDF]
, 2012 Little is known about the reproductive biology of the codfishes (Gadidae). Lacking direct observations, the study of secondary sexual characteristics can provide cues to their reproductive biology and behaviour.

Ecological Applications, Volume 36, Issue 1, January 2026.Abstract Understanding patterns of habitat use across trophic levels and the physical drivers of multispecies aggregations is essential to inform ecosystem‐based management. To achieve this, we quantified the spatial distribution and co‐occurrence of hotspots (defined using the Getis‐Ord statistic) for euphausiids and nine of their commercially ...

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.

Kelp bed variability and fish population dynamics in Kachemak Bay, Alaska [PDF]
, 2004 Thesis (M.S.) University of Alaska Fairbanks, 2004Understanding interactions between kelp beds and fishes is essential because anthropogenic changes and natural variability in these beds (composition, density, and distribution) may affect available ...

Quantifying physiological influences on otolith microchemistry [PDF]
, 2015 Trace element concentrations in fish earstones (‘otoliths’) are widely used to discriminate spatially discrete populations or individuals of marine fish, based on a commonly held assumption that physiological influences on otolith composition are minor ...

Methods in Ecology and Evolution, Volume 17, Issue 1, Page 207-218, January 2026.Abstract Species distribution models (SDMs) are widely used to standardize spatially unbalanced data, project climate impacts and identify habitat for conservation. SDMs typically estimate the impact of local environmental conditions by estimating a dome‐shaped or non‐parametric ‘environmental response function’.
