A combination of genetic and phenotypic characterization of spring- and autumn-spawning herring suggests gene flow between populations
(Peer reviewed; Journal article, 2020)Atlantic herring (Clupea harengus) has complex population structure and dynamics including diverse life histories and spawning times with spring and autumn spawning as the most common modes. Originally, spawning herring ... -
A metapopulation model reveals connectivity-driven hotspots in treatment resistance evolution in a marine parasite
(Peer reviewed; Journal article, 2022)In salmon aquaculture, the sustainable management of salmon lice (Lepeophtheirus salmonis) is limited by the adaptive capacity of the parasite. This is evident in the repeated evolution of pesticide resistance in the salmon ... -
A method to automatically detect fish aggregations using horizontally scanning sonar
(Journal article; Peer reviewed, 2018)Pelagic fishes are a major source of protein and unsaturated fatty acids, and robust management is critical to avoid overfishing. Fisheries management is often supported by indices from scientific acoustic-trawl surveys, ... -
Accuracy of VMS data from Norwegian demersal stern trawlers for estimating trawled areas in the Barents Sea
(Journal article; Peer reviewed, 2011-06-08)The accuracy of vessel monitoring system (VMS) data, used to determine fishing activity in the trawl fishery for gadoids in the Barents Sea, was studied by observer notes and Global Positioning System (GPS) data from two ... -
Acoustic classification in multifrequency echosounder data using deep convolutional neural networks
(Peer reviewed; Journal article, 2020)Acoustic target classification is the process of assigning observed acoustic backscattering intensity to an acoustic category. A deep learning strategy for acoustic target classification using a convolutional network is ... -
'Adaptation science' is needed to inform the sustainable management of the world's oceans in the face of climate change
(Peer reviewed; Journal article, 2022)The global response to the challenge of increasingly rapid and severe climate change is shifting from a focus on mitigation and remediation of impacts to a pragmatic adaptation framework. Innovative adaptive solutions that ... -
Addressing class imbalance in deep learning for acoustic target classification
(Peer reviewed; Journal article, 2023)Acoustic surveys provide important data for fisheries management. During the surveys, ship-mounted echo sounders send acoustic signals into the water and measure the strength of the reflection, so-called backscatter. ... -
An evaluation of compiled single-beam bathymetry data as a basis for regional sediment and biotope mapping
(Journal article; Peer reviewed, 2013-10-18)Maps of surficial sediment distribution and benthic habitats or biotopes provide invaluable information for ocean management and are at the core of many seabed mapping initiatives, including Norway's national offshore ... -
Annotating otoliths with a deep generative model
(Peer reviewed; Journal article, 2023)Otoliths are a central information source for fish ecology and stock management, conveying important data about age and other life history for individual fish. Traditionally, interpretation of otoliths has required skilled ... -
Application of an unsupervised clustering algorithm on in situ broadband acoustic data to identify different mesopelagic target types
(Peer reviewed; Journal article, 2021)The mesopelagic zone (200–1000 m depth) contains high fish species diversity but biomass and abundances are uncertain yet essential to understand ecosystem functioning. Hull-mounted acoustic systems (usually 38 kHz) often ... -
Applications and analytical approaches using imaging sonar for quantifying behavioural interactions among aquatic organisms and their environment
(Peer reviewed; Journal article, 2023)For many aquatic animals, distributional patterns, trophodynamic relationships, and reproductive activity are driven by complex biotic and abiotic ecosystem interactions that influence behaviour. Linking behavioural ... -
Applying Bayesian model selection to determine ecological covariates for recruitment and natural mortality in stock assessment
(Peer reviewed; Journal article, 2021)Incorporating ecological covariates into fishery stock assessments may improve estimates, but most covariates are estimated with error. Model selection criteria are often used to identify support for covariates, have some ... -
Aquaculture-driven evolution: distribution of pyrethroid resistance in the salmon louse throughout the North Atlantic in the years 2000–2017
(Peer reviewed; Journal article, 2020)The parasitic salmon louse, and its documented resistance to chemotherapeutants, represents the most persistent environmental challenge to global salmonid aquaculture. We used a genetic marker associated with pyrethroid ... -
Assessing the state of the Barents Sea using indicators: How, when, and where?
(Peer reviewed; Journal article, 2021)Two end-to-end ecosystem models, NORWECOM.E2E and NoBa Atlantis, have been used to explore a selection of indicators from the Barents Sea Management plans (BSMP). The indicators included in the BSMP are a combination of ... -
Balanced harvest: Utopia, failure, or a functional strategy?
(Journal article; Peer reviewed, 2016-03-16)Since “balanced harvest” was proposed in 2010 as a possible tool in the operationalization of the ecosystem approach to fisheries (EAF), the concept gained extensive international attention. Because maintaining ecosystem ... -
Balanced harvesting in a variable and uncertain world – a case study from the Barents Sea.

Barents Sea cod (Gadus morhua) diet composition: long-term interannual, seasonal, and ontogenetic patterns
(Journal article; Peer reviewed, 2019)Atlantic cod (Gadus morhua) is an ecologically and commercially important species in the North-Atlantic region. Cod is a top predator and information on its trophic ecology is integral for understanding predator–prey ... -
Barents Sea plankton production and controlling factors in a fluctuating climate
(Peer reviewed; Journal article, 2021)The Barents Sea and its marine ecosystem is exposed to many different processes related to the seasonal light variability, formation and melting of sea-ice, wind-induced mixing, and exchange of heat and nutrients with ... -
Behavioural responses of wild anadromous Arctic char experimentally infested in situ with salmon lice
(Peer reviewed; Journal article, 2022)Salmon lice can impact the marine behaviour, growth, and survival of salmonids, but little is known about their effects on Arctic char. We present behavioural responses from the first dose-response experiment with wild ... -
