Fine-scale population dynamics in a marine fish species inferred from dynamic state-space models
(Peer reviewed; Journal article, 2017) -
Fine-scale spatial variation of northern shrimp and Atlantic cod across three Norwegian fjord systems and implications for management
(Peer reviewed; Journal article, 2023)The spatial complexity of coastal ecosystems represents a challenge for the management of inshore resources. Here we compared two large fjord systems in northern Norway that have been closed for all bottom trawling for 50 ... -
Fine-scale vertical structure of sound-scattering layers over an east border upwelling system and its relationship to pelagic habitat characteristics
(Peer reviewed; Journal article, 2020)Understanding the relationship between sound-scattering layers (SSLs) and pelagic habitat characteristics is a substantial step to apprehend ecosystem dynamics. SSLs are detected on echo sounders representing aggregated ... -
Finite-amplitude sound propagation effects in volume backscattering measurements for fish abundance estimation
(Peer reviewed; Journal article, 2022)Abstract – Scientific advice for governmental management of marine resources relies on acoustical observation methods. Quantification and identification of fish and plankton species are often achieved using multi-frequency ... -
First Assessment of the Impacts of the COVID-19 Pandemic on Global Marine Recreational Fisheries
(Peer reviewed; Journal article, 2021)This work is the result of an international research effort to determine the main impacts of the COVID-19 pandemic on marine recreational fishing. Changes were assessed on (1) access to fishing, derived from lockdowns and ... -
First description of a Lophelia pertusa reef complex in Atlantic Canada
(Peer reviewed; Journal article, 2017)For the first time, we describe a cold-water coral reef complex in Atlantic Canada, discovered at the shelf break, in the mouth of the Laurentian Channel. The study is based on underwater video and sidescan sonar. The reef ... -
First estimates of metabolic rate in Atlantic bluefin tuna larvae
(Peer reviewed; Journal article, 2020)Atlantic bluefin tuna is an iconic scombrid species with a high commercial and ecological value. Despite their importance, many physiological aspects, especially during the larval stages, are still unknown. Metabolic rates ... -
First identification of mycobacteriosis in Atlantic mackerel (Scomber scombrus)
(Peer reviewed; Journal article, 2023)Mycobacterium infection in fish is a well-known disease problem globally, mainly in the farming of ornamental fish or fish for food. Less is known about the prevalence, distribution and the effects such infections have on ... -
First indications that northern bottlenose whales are sensitive to behavioural disturbance from anthropogenic noise
(Journal article; Peer reviewed, 2015-06-03)Although northern bottlenose whales were the most heavily hunted beaked whale, we have little information about this species in its remote habitat of the North Atlantic Ocean. Underwater anthropogenic noise and disruption ... -
First insights into the movements and vertical habitat use of blue marlin (Makaira nigricans) in the eastern North Atlantic
(Peer reviewed; Journal article, 2022)The blue marlin (Makaira nigricans) is a vulnerable migratory fish inhabiting tropical and subtropical pelagic waters of the Atlantic, Pacific and Indian Oceans. The biology and spatial ecology of the species in the eastern ... -
The first mitochondrial 5-methylcytosine map in a non-model teleost (Oreochromis niloticus) reveals extensive strand-specific and non-CpG methylation
(Peer reviewed; Journal article, 2021)DNA methylation is one of the main epigenetic mechanisms that regulate gene expression in a manner that depends on the genomic context and varies considerably across taxa. This DNA modification was first found in nuclear ... -

(Peer reviewed; Journal article, 2021)DNA methylation is one of the main epigenetic mechanisms that regulate gene expression in a manner that depends on the genomic context and varies considerably across taxa. This DNA modification was first found in nuclear ... -
First record of cuticle bands in the stomach ossicles of the red king crab Paralithodes camtschaticus (Tilesius, 1815) (Decapoda: Anomura: Lithodidae) from Norway.
(Journal article; Peer reviewed, 2019)The red king crab Paralithodes camtschaticus (Tilesius, 1815) is a large predator intentionally introduced to the Barents Sea and adjacent fjords in the 1960s. Its establishment has given rise to both a high-value fishery ... -
First report of mobile tigecycline resistance gene tet(X4)-harbouring multidrug-resistant Escherichia coli from wastewater in Norway
(Peer reviewed; Journal article, 2021)The mobile tigecycline resistance gene tet(X4), conferring resistance to all tetracyclines, is largely reported from China, however the global spread of such a novel resistance mechanism is a concern for preserving the ... -
First thorough assessment of de novo oocyte recruitment in a teleost serial spawner, the Northeast Atlantic mackerel (Scomber scombrus) case
(Peer reviewed; Journal article, 2021)The understanding of teleost fecundity type (determinate or indeterminate) is essential when deciding which egg production method should be applied to ultimately estimate spawning stock biomass. The fecundity type is, ... -
Fish assemblages at the Yermak Plateau and in northern Svalbard waters during the period 2012-2020
(Peer reviewed; Journal article, 2023)During several surveys covering the north-western and northern Svalbard waters, and the deeper Yermak Plateau north of Svalbard during the period 2012–2020, 291 standardized hauls with a demersal trawl were made. All fishes ... -

Fish Assemblages of a Sub-Arctic Fjord Show Early Signals of Climate Change Response Contrary to the Benthic Assemblages
(Peer reviewed; Journal article, 2022)Arctic benthic ecosystems are facing high-speed environmental changes, such as decreased sea ice coverage, increased temperature and precipitations, as well as the invasion by non-indigenous species. Few sub-arctic fjords ... -
Fish community dynamics in a coastal no-take marine protected area compared to a harvested area before and after protection from fishing
