A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery
(Journal article; Peer reviewed, 2012-12-12)Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ... -
A new model for simulating growth in fish
(Journal article; Peer reviewed, 2014-01-16)A real dynamic population model calculates change in population sizes indepen- dent of time. The Beverton & Holt (B&H) model commonly used in fish assessment includes the von Bertalanffy growth function which has age or ... -
A rare observation of Atlantic halibut larvae (Hippoglossus hippoglossus) in Skjerstadfjorden, North Norway.
(Journal article; Peer reviewed, 2013-06-28)Four larvae of Atlantic halibut (Hippoglossus hippoglossus) were collected during a larval survey for Atlantic cod (Gadus morhua) in true inshore and shallow locations in the Norwegian fjord system Skjerstadfjorden. This ... -
A review of the battle for food in the Barents Sea: cod vs. marine mammals
(Journal article; Peer reviewed, 2015-03-25)Cod, harp seal and minke whale are the main top predators in the Barents Sea ecosystem. In the last decade, the abundance of cod has increased considerably, and is at a record high level. In spite of this, the growth and ... -

Abundance estimation of Northeast Atlantic mackerel based on tag recapture data - A useful tool for stock assessment?
(Journal article; Peer reviewed, 2010-10)In the present study we utilize tag recapture data to estimate year class abundance and spawning stock biomass of mackerel (Scomber scombrus L.) in the Northeast Atlantic for the period 1986–2008. On average 20,000 jigged ... -
Age, growth, and mortality of the myctophid fish, Benthosema glaciale (Reinhardt), from western Norway
(Journal article; Peer reviewed, 1973-05-18)Age and growth of Benthosema glaciale collected by midwater trawl in western Norway have been studied. Otoliths were used for age determination. The mean annual mortality in age groups I to IV was 52%. Older specimens were ... -
An assessment of the spatial scale of local adaptation in brown trout (Salmo trutta L.): footprints of selection at microsatellite DNA loci
(Journal article; Peer reviewed, 2011-01-12)Local adaptation is considered a paradigm in studies of salmonid fish populations. Yet, little is known about the geographical scale of local adaptation. Is adaptive divergence primarily evident at the scale of regions or ... -
An evaluation of 0-group abundance indices of Barents Sea fish stocks
(Journal article; Peer reviewed, 2009)The International 0-group fish survey in the Barents Sea (1965-2002) aimed to give initial indication of the recruiting year class strengths. Since 2003 the 0-group survey has been a part of a Joint Norwegian-Russian ... -
Analytical and statistical review of procedures for collection and analysis of commercial fishery data used for management and assessment of groundfish stocks in the U.S. exclusive economic zone off Alaska
(Research report, 1997)Effective management of multi-species fisheries requires reliable estimates of the amount and composition of catch and bycatch. In this report, we present the results of analyses of observer program data ... -
Antarctic krill swarm characteristics in the Southeast Atlantic sector of the Southern Ocean
(Journal article; Peer reviewed, 2012-09-28)Knowledge about swarm dynamics and underlying causes is essential to understand the ecology and distribution of Antarctic krill Euphausia superba. We collected acoustic data and key environmental data continuously across ... -

(Journal article; Peer reviewed, 2012-02-17)A total of 30 isolates of Francisella noatunensis subsp. noatunensis isolated from Atlantic cod Gadus morhua L. were tested for susceptibility, in the form of minimal inhibitory concentration (MIC) values, against the ... -
The Barents Sea capelin stock 1972-1997. A synthesis of results from acoustic surveys
(Journal article; Peer reviewed, 1998-05-15)The abundance of the Barents Sea capelin stock has been monitored using acoustic methods since 1972. Today, 25 years later, it is one of the few stocks within the ICES area for which an annual acoustic stock size estimate ... -
