Feeding of mature cod (Gadus morhua) on the spawning grounds in Lofoten
(Journal article; Peer reviewed, 2008-03-19)Many authors state that cod (Gadus morhua) do not feed during the spawning period. However, this more or less established fact has rarely been investigated in the field. Here, the content of stomachs from Northeast Arctic ... -
Fish avoidance of research vessels and the efficacy of noise-reduced vessels: a review
(Journal article; Peer reviewed, 2012-10-19)It has long been recognized that fish can avoid approaching vessels and that these behaviours can bias fishery surveys. Underwater noise is considered the primary stimulus, and standards for research vessel noise have been ... -
Fish community dynamics in a coastal no-take marine protected area compared to a harvested area before and after protection from fishing
(Peer reviewed; Journal article, 2023)An ecosystem's ability to maintain key functions during environmental change is largely determined by its biodiversity. We compared fish species composition, richness, diversity, catch per unit effort (CPUE), and fish size ... -
Fish consumption by great cormorants in Norwegian coastal waters—a human-wildlife conflict for wrasses, but not gadids
(Peer reviewed; Journal article, 2021)Piscivorous wildlife is often perceived as competitors by humans. Great cormorants of the continental subspecies (Phalacrocorax carbo sinensis) in the Baltic and North Sea increase, while local cod (Gadus morhua) stocks ... -
Five centuries of cod catches in Eastern Canada
(Peer reviewed; Journal article, 2021)The fishery for Northern Atlantic cod (Gadus morhua) off Newfoundland and Labrador, Eastern Canada, presents the most spectacular case of an exploited stock crashed in a few decades by an industrial bottom trawl fishery ... -
Flexible behaviour in a mesopelagic fish (Maurolicus muelleri)
(Peer reviewed; Journal article, 2021)Variability of mesopelagic scattering layers is often attributed to environmental conditions or multi-species layer composition. Yet, little is known about variation in behaviour among the individuals forming scattering ... -

From siphonophores to deep scattering layers: Uncertainty ranges for the estimation of global mesopelagic fish biomass
(Peer reviewed; Journal article, 2019)The mesopelagic community is important for downward oceanic carbon transportation and is a potential food source for humans. Estimates of global mesopelagic fish biomass vary substantially (between 1 and 20 Gt). Here, we ... -
Gaussian mixture models reveal highly diverse targeting tactics in a coastal fishing fleet
(Peer reviewed; Journal article, 2022)Fishermen make repeated choices with respect to when, where, and how to catch their target species. While these targeting tactics—and the factors shaping them—are known to fishers and some experts, knowledge about them is ... -

Genetic analysis of goldsinny wrasse reveals evolutionary insights into population connectivity and potentialevidence of inadverent translocationvia aquaculture.

Genetic differentiation between inshore and offshore populations of northern shrimp (Pandalus borealis)
(Peer reviewed; Journal article, 2021)Many marine organisms have a permanent presence both inshore and offshore and spawn in multiple areas, yet their status as separate populations or stocks remain unclear. This is the situation for the northern shrimp (Pandalus ... -
Genetic population structure in Norway lobster (Nephrops norvegicus): management regime under panmixia
(Peer reviewed; Journal article, 2023)Investigations of genetic stock structure sometimes reveal a mismatch between management units and biological units. In Scandinavian waters, Norway lobster (Nephrops norvegicus) is divided into two management units (the ... -
Genetic study reveals local differentiation persisting in the face of high connectivity and a genomic inversion likely linked with sexual antagonism in a common marine fish
(Peer reviewed; Journal article, 2023)Sustainable harvest of wild populations requires knowledge of the underlying population structure. The focus of this study is on goldsinny wrasse (Ctenolabrus rupestris), a small marine fish inhabiting coastal waters of ... -
Geographic distribution, abundance, diet, and body size of invasive pink salmon (Oncorhynchus gorbuscha) in the Norwegian and Barents Seas, and in Norwegian rivers
(Peer reviewed; Journal article, 2022)We report for the first time the geographic distribution, abundance, diet, and body size of invasive pink salmon (Oncorhynchus gorbuscha) in the Norwegian and Barents Seas and Norwegian coast and rivers. We found that pink ... -
Geographic variability of sardine dynamics in the Iberian Biscay region
(Journal article; Peer reviewed, 2009-04)The spatio-temporal variability in the distribution, demographic structure, recruitment, and mortality of sardine within the Iberian Biscay region is described using area-disaggregated data collected during acoustic surveys ... -
Good ethics or political and cultural censoring in science?
(Journal article; Peer reviewed, 2012-02-13)Peer-reviewed journals are the cornerstones to communicating scientific results. They play a crucial role in quality assurance through the review process, but they also create opportunities for discussions in the scientific ... -
Growth of Barents Sea capelin (Mallotus villosus) in relation to zooplankton abundance
(Journal article; Peer reviewed, 2002)Because capelin feed on zooplankton, the availability of the latter may be a limiting factor for capelin growth in at least some areas and at certain times. It was therefore hypothesized that a relationship exists between ... -

Half a century of high-latitude fisheries oceanography research on the "recruitment problem" in Northeast Arctic cod (Gadus morhua)
(Peer reviewed; Journal article, 2023)Predicting recruitment in a reliable fashion is a great challenge within operational fisheries advice. Here, we consulted the unique but undercommunicated IMR Cod Larva Project (1975–1990), its spin-offs, placed in an ...
