Rapid genome modifications including chromosomal fusions and large-scale inversions are key features in Arctic codfish species [PDF]
Genome BiologyBackground Genome evolvability involves activation of transposable elements (TEs) that result in novel genomic rearrangements, including translocations, deletions, duplications, as well as larger structural reorganizations, such as chromosomal inversions

Rebuilding the Northeast Arctic Cod Fisheries – Economic and Social Issues
Arctic Review on Law and Politics, 2014 The Northeast Arctic cod (NEA cod) fisheries in Norway are now one of the richest cod fisheries in the world. In the past the fishery has experienced several stock declines and low economic returns.

Reference genome bias in light of species-specific chromosomal reorganization and translocations [PDF]
Genome BiologyBackground Whole-genome sequencing efforts, have during the past decade, unveiled the central role of genomic rearrangements—such as chromosomal inversions—in evolutionary processes, including local adaptation in a wide range of taxa. However, employment

Northeast arctic cod stock and fishery dynamics
Frontiers in Marine Science, 2015 Northeast arctic cod stock is one of a most valuable target of fisheries in the Barents Sea. The catches of cod for the period 1960-2014 are widely changed.

Fisheries change spawning ground distribution in northeast Arctic cod [PDF]
Biol Lett, 2010 Prior to the 1920s, the northeast Arctic (NA) cod were caught at spawning grounds ranging from the southernmost to the northernmost parts of the Norwegian coast, but have for the last 50 yr mainly been caught around the Lofoten archipelago and northwards.

The physiological response of the Arctic key species Polar cod, Boreogadus saida, to hypoxia in a warming ocean: critical oxygen levels and swimming performance [PDF]
BMC ZoologyGlobal warming has already caused a loss of nearly 50% Arctic sea-ice coverage since the 1980s. This sea-ice loss strengthens summer stratification of the ocean’s water column and, consequently, hypoxic zones may form in the deep-water layers.

Resource‐driven colonization by cod in a high Arctic food web [PDF]
Ecology and Evolution, 2020 Climate change is commonly associated with many species redistributions and the influence of other factors may be marginalized, especially in the rapidly warming Arctic.

Exploration of short-term predictions and long-term projections of Barents Sea cod biomass using statistical methods on data from dynamical models. [PDF]
PLoS ONEThis study aims to explore how well simple statistical modeling can generate short-term predictions and long-term projections of the total biomass of the Northeast Arctic stock of Atlantic cod (Gadus Morhua) inhabiting the Barents Sea.
