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 ... -

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 and oil in the Lofoten–Barents Sea system: synoptic review of the effect of oil spills on fish populations
(Journal article; Peer reviewed, 2007-06-06)The Lofoten-Barents Sea area, which contains some of the most valuable fish stocks of the Atlantic Ocean, is being considered for offshore oil production. We review the effects of a hypothetical oil spill on fishes in this ... -
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 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 ... -
Fish for food and nutrition security in Ghana: Challenges and opportunities
(Peer reviewed; Journal article, 2020)Fish is an important dietary source of micronutrients, particularly in low-and middle-income countries. In Ghana, effective management of fish and the fisheries is essential for food, economic and nutrition security and ... -
Fish harvesting, marine reserves, and distribution of individuals over space
(Journal article; Peer reviewed, 2004-08-05)We analysed exploitation of populations that are partly protected in a marine harvest refuge to prevent their over-harvesting in the remaining unprotected area. We carried out our analysis by introducing the model of ideal ... -
Fish protection during fish production. Organizational conditions for fish welfare
(Peer reviewed; Journal article, 2021)Too many salmon die during production at Norwegian fish farms. Earlier research shows that most farmed salmon die in operations partly related to protection of the wild salmon (from salmon lice), but it is not known how ... -
The fish swimbladder as an acoustic waveguide

Fish target strengths for use in echo integrator surveys
(Journal article; Peer reviewed, 1987)In situ measurements of fish target strength are selected for use in echo integrator surveys at 38 kHz. The results are expressed through equations in which the mean target strength TS is regressed on the mean fish length ... -
Fish welfare based classification method of ocean current speeds at aquaculture sites
(Journal article; Peer reviewed, 2019)A major trend in marine aquaculture is to move production to more exposed sites with occasionally rough ocean current events. However, it is unclear whether fish will thrive in these extreme environments, since thorough ... -
Fish welfare in offshore salmon aquaculture
(Peer reviewed; Journal article, 2020)To accommodate further growth in the Atlantic salmon aquaculture industry, new production sites may well be established at more exposed locations along the coast or even offshore. Here, fish will encounter strong currents ...
