Liver energy, atresia and oocyte stage influence fecundity regulation in Northeast Arctic cod
(Journal article; Peer reviewed, 2010-04-08)Marine ecosystems are changing; global warming-induced increases in water temperatures and fishing have caused truncated age structures and small sizes at maturity in many stocks. This may affect both populations’ total ... -
Long-term fluctuations in cod and pollack along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 1998-02-12)We tested whether the long-term fluctuations in abundance of 0-group cod Gadus morhua and pollack Pollachius pollachius sampled from 1919 to 1994 at 38 stations along the Norwegian Skagerrak coast might be related to the ... -

Mating competition between farmed and wild cod Gadus morhua
(Journal article; Peer reviewed, 2010-08-18)Increasing numbers of hatchery-produced fish entering marine environments has caused concern over potential fitness depressions in wild populations, yet no study has addressed the likelihood of hybridisation between farmed ... -
Molecular Genetic Analysis of Stomach Contents Reveals Wild Atlantic Cod Feeding on Piscine Reovirus (PRV) Infected Atlantic Salmon Originating from a Commercial Fish Farm
(Journal article; Peer reviewed, 2013-04-19)In March 2012, fishermen operating in a fjord in Northern Norway reported catching Atlantic cod, a native fish forming an economically important marine fishery in this region, with unusual prey in their stomachs. It was ... -
Observations of cod reaction to trawling noise
(Working paper, 1988-04)Observations made from a stationary echo sounder, passed by a trawling vessel, clearly demonstrate the flight reaction of cod as a response to the noise from the vessel. Horizontal dispersal and downward swimming has been ... -
Population dynamics of cod Gadus morhua in the North Sea region: biological density-dependent and climatic density-independent effects
(Journal article; Peer reviewed, 2005-11-04)Through the statistical modeling of monitoring data, we assess the ecological interlinkages between cod Gadus morhua L. in the North Sea, Skagerrak and Kattegat—regions which typically have been considered separate management ... -
Prey selection by larval haddock and cod on copepods with species-specific behavior: an individual-based model analysis
(Journal article; Peer reviewed, 2009-12-09)Coupled biological-physical models of larval fish have become a widely used tool for studying recruitment variability. Within these models, foraging components include prey selection as a determinant of food availability ... -
Pronounced long-term juvenation in the spawning stock of Arcto-Norwegian cod (Gadis morhua) and possible consequences for recruitment
(Journal article; Peer reviewed, 2008-01)The oldest and largest individuals are disappearing from many fish stocks worldwide as a result of overexploitation. This has been suggested to impair recruitment through decreasing the reproductive capacity of the spawners ... -
Reconstructing the stock–recruit relationship for Northeast Arctic cod using a bioenergetic index of reproductive potential
(Journal article; Peer reviewed, 2000)Correlation and simulation analyses suggest that, for the Northeast Arctic (NA) cod stock, the total lipid energy (TLE (kJ)) contained in the livers of mature females is proportional to total egg production, making TLE a ... -

Retention of Coastal Cod Eggs in a Fjord Caused by Interactions between Egg Buoyancy and Circulation Pattern
(Journal article; Peer reviewed, 2011-08-01)Norwegian coastal cod form a stationary population of Atlantic cod Gadus morhua consisting of several genetically separated subpopulations. A small-scale differentiation in marine populations with pelagic eggs and larvae ... -

Settling-depth vs. genotype and size vs. genotype correlations at the Pan I locus in 0-group Atlantic cod Gadus morhua
(Journal article; Peer reviewed, 2012-11-14)We sampled 0-group juvenile Atlantic cod Gadus morhua L. within fjords and offshore in northern Norway from 1994 to 2008 using different gears for the 3 sampling depths: shore seine (0−3 m), pelagic trawl (various depths), ... -
Spatial patterns of the temporal dynamics of three gadoid species along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 1997-08-28)Time series from an extensive research survey of juveniles of cod Gadus morhua, pollack Pollachius pollachius and whiting Merlangius merlangus sampled from 1919 to 1994 at 38 stations along the Norwegian Skagerrak coast ... -
Sperm characteristics and competitive ability in farmed and wild cod
(Journal article; Peer reviewed, 2009-01-27)The development of cod aquaculture has raised concerns about its effect on wild stocks. One risk is hybridisation between escapees and wild cod, causing genetic introgression, and, potentially, fitness depressions in wild ...
