(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-16)Marine plastic pollution and continuous capture of marine animals, so-called “ghost fishing”, by abandoned, lost, or otherwise discarded fishing gear (ALDFG) are global concerns. This study investigated whether biodegradable polylactic acid (PLA) monofilaments can be used to replace conventionally used non-biodegradable polyamide (PA) in trammel net fishery for limiting ALDFG associated effects. It ... -
Comparison of the efficiency and modes of capture of biodegradable versus nylon gillnets in the Northeast Atlantic cod (Gadus morhua) fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-01)Modern gillnets are usually made of nylon with high breaking strength, suitable elasticity and durability making them an efficient fishing gear. Lost, abandoned, or discarded gillnets at sea cause plastic pollution and can continue capturing marine animals over long periods of time. Biodegradable materials are being developed to replace nylon in gillnets. However, biodegradable gillnets have shown ... -
Complex and divergent histories gave rise to genome-wide divergence patterns amongst European whitefish (Coregonus lavaretus)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-15)Pleistocene glaciations dramatically affected species distribution in regions that were impacted by ice cover and subsequent postglacial range expansion impacted contemporary biodiversity in complex ways. The European whitefish, Coregonus lavaretus, is a widely distributed salmonid fish species on mainland Europe, but in Britain it has only seven native populations, all of which are found on the ... -
The components of a food traceability system
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-03)<p><i>Background</i>: Traceability of food products has become the focus of regional and national legislation, of many research and technical development initiatives and projects, and of many scientific articles. However, most of the scientific publications do not differentiate between the components of a traceability system, and those who do to some degree use inconsistent terminology and definitions. ... -
Composition of exosomes derived from Atlantic salmon (Salmo salar) head kidney leukocytes
(Conference object; Konferansebidrag, 2015-06-28)Exosomes are secreted nanosize vesicles (30−100 nm) derived from multivesicular endosomes. Exosomes are released by different immune cell types, including T- and B-lymphocytes, mast cells and antigen-presenting cells (APCs). The composition of exosomes - including protein and RNA content reflects their endosomal origin and the type of cells that produce them. Mammalian APCs produce large amounts ... -

Conflicts and trade-offs in implementing the Common Fisheries Policy (CFP) discard policy
(Research report; Forskningsrapport, 2018-05-01)The introduction of the Landing Obligation (LO) is one of the most significant reform elements in the 2013 Common Fisheries Policy (CFP). In order to assess how the LO performs as a policy instrument, it is essential to understand the background, objectives and motivation that led to the policy being adopted. With these objectives in mind, a desk-study was first carried out to review relevant policy ... -
Conservation of Genomic Information in Multiple Displacement Amplified Low-Quantity Metagenomic Material from Marine Invertebrates
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-02)Marine invertebrate microbiomes have been a rich source of bioactive compounds and interesting genomic features. In cases where the achievable amounts of metagenomic DNA are too low for direct sequencing, multiple displacement amplification (MDA) can be used for whole genome amplification. However, MDA has known limitations which can affect the quality of the resulting genomes and metagenomes. ... -

Consumer preference for eco-labelled aquaculture products in Vietnam
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-01)Product labelling with eco-certifications is market-based incentive tool for sustainable aquaculture, thus mitigating negative environmental impacts. The aims of this study are to investigate: i) whether consumers prefer eco-labelled (eco-certified) shrimps over conventional (non-certified) shrimp; and ii) whether consumers prefer specific eco-label (eco-certification logo) over others. The study ... -
Coproducing Sea Ice Predictions with Stakeholders Using Simulation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-15)Forecasts of sea ice evolution in the Arctic region for several months ahead can be of considerable socioeconomic value for a diverse range of marine sectors and for local community supply logistics. However, subseasonal-to-seasonal (S2S) forecasts represent a significant technical challenge, and translating user needs into scientifically manageable procedures and robust user confidence requires ... -
Cost-benefit analysis of aquaculture expansion in Arctic Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-22)According to governmental plans, Norway faces huge expansions in the production of farmed Atlantic salmon. However, it is municipalities that designate coastal areas to aquaculture activities and their motivation depends on net benefits at municipal level from such use. Yet, there is little empirical evidence on costs and benefits of using coastal areas to aquaculture activities. We set up a ... -
Could green artificial light reduce bycatch during Barents Sea Deep-water shrimp trawling?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-31)The Nordmøre grid is widely used in shrimp trawls to reduce the bycatch of fish species. However, small-sized fish species and juveniles still pass through the grid and enter the codend, along with the targeted shrimp. This bycatch of small fish has a negative impact on the ecosystem due to increased fish mortality, and leads to additional sorting work onboard. Some small-sized fish that enter the ... -
CpG oligonucleotides bind TLR9 and RRM-Containing proteins in Atlantic Salmon (Salmo salar)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Background: Bacterial DNA is well-known for its potent immunostimulatory properties which have been attributed to the abundance of CpG dinucleotides within the genomes of prokaryotes. Research has found that mammalian TLR9 is a receptor which mediates the immune response to CpG DNA; however, its functional properties in non-mammalian vertebrates are still poorly characterized. Leukocytes isolated ... -
CpG- and LPS-activated MAPK signaling in in vitro cultured salmon (Salmo salar) mononuclear phagocytes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)The Mitogen-activated protein kinases (MAPK) are involved in transmitting intracellular signals downstream of diverse cell surface receptors and mediate the response to ligands such as growth factors, hormones and cytokines. In addition, MAPK are critically involved in the innate immune response to pathogen-derived substances, commonly referred to as pathogen-associated molecular patterns (PAMPs), ... -
CpGs Induce Differentiation of Atlantic Salmon Mononuclear Phagocytes Into Cells With Dendritic Morphology and a Proinflammatory Transcriptional Profile but an Exhausted Allostimulatory Activity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-13)Due to their ability to present foreign antigens and prime naïve T cells, macrophages, and dendritic cells (DCs) are referred to as professional antigen-presenting cells (APCs). Although activated macrophages may function as APCs, these cells are particularly effective at directly engaging pathogens through phagocytosis, and production of antimicrobial compounds. On the other hand, DCs possess superb ... -
Creating political spaces at sea - governmentalisation and governability in Norwegian fisheries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-30)How do technologies of power make the world governable? The understanding of how management techniques create governability remains rather poor. In this article, I analyse how spatial regulation in Norwegian fisheries direct human behaviour towards scientific, political, and administrative objectives. Like other fisheries’ regulations, they contribute to governmentalisation and governability, and ...
