Willingness to pay for unfamiliar public goods: Preserving cold-water coral in Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-17)The world's largest concentration of cold-water coral (CWC) is found off the Norwegian coast. Most CWC discoveries are recent, posing new challenges for Norwegian coastal and fishery authorities regarding the management of deep-sea resources. Scientific knowledge of CWC is limited, and many citizens have not even heard about them. This creates problems for the application of the stated preference ... -

The Norwegian coastal employment system: What It Was and What It Is
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)Norwegian fisheries have undergone tremendous changes, due to technological developments and the introduction of resource management. In addition, societal changes and in particular the introduction of formal requirements and the formalization of training and education, have also greatly affected the fishing fleet. Jentoft and Wadel (1984) described the Coastal Employment System. This system was ... -
Institutional challenges for effective governance of consumptive wildlife tourism: case studies of marine angling tourism in Iceland and Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-08)Good governance of consumptive wildlife tourism, a complex socio-ecological system, requires finding the right balance between natural resource and tourism management. Fishing takes the lead globally as the most popular product offering within consumptive wildlife tourism, and both Iceland and Norway offer a marine angling tourism product. The two countries offer similar pristine Arctic fjord ... -
Adjuvant activity of fish type I interferon shown in a virus DNA vaccination model
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-09)There is a need for more efficient vaccines to combat viral diseases of Atlantic salmon and other farmed fish. DNA vaccines are highly effective against salmonid rhabdoviruses, but have shown less effect against other viruses. In the present work we have studied if type I IFNs might be used as adjuvants in fish DNA vaccines. For this purpose we chose a DNA vaccine model based on the hemagglutin ... -
Infectious pancreatic necrosis virus proteins VP2, VP3, VP4 and VP5 antagonize IFNa1 promoter activation while VP1 induces IFNa1
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015)Infectious pancreatic necrosis virus (IPNV) is one of the major viral pathogens causing disease in farmed Atlantic salmon worldwide. In the present work we show that several of the IPN proteins have powerful antagonistic properties against type I IFN induction in Atlantic salmon. Each of the five IPNV genes cloned into an expression vector were tested for the ability to influence activation of the ... -

The Political Game of European Fisheries Management
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-14)European fisheries activities are subject to a hierarchy of regulatory authorities. This raises questions regarding the implications of strategic interaction between different authority levels concerning the regulation of these activities. We apply a bio-economic objective function where fishers and regulators have environmental, economic and social preferences, and where fishers are subject to ... -
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 ... -
Demographic and economic disparities among Arctic regions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-20)We use demographic and economic indicators to analyze spatial differences and temporal trends across 18 regions surrounding the Arctic Ocean. Multifactor and cluster analysis were used on 10 indicators reflecting income, employment and demography from 1995 to 2008. The main difference is between regions with high population densities, low natural growth rate, and low unemployment (Russia, Norway ... -
"Getting ItRight":The Birth of a New EU Common Fishery Policy? Legislative and Legal Perspectives on the Annulling of the "Five Structural Failings"
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015)This lex ferenda article examines EU efforts to change the criticized and now-repealed 2002 “top-down” management regulation with its discard system, vessel decommissioning, fishing effort management, and quota allocations. The 2013 regulation’s objective is to remedy the Common Fisheries Policy’s “five structural failings.” Unfortunately, the new regulations have failed to improve the situation. ... -
Ecological linkages in a Caribbean estuary bay.
(Journal article; Tidsskriftartikkel, 2015-08-06)Central America and the western Caribbean form a center of freshwater and marine biodiversity that is now receiving attention in ecological and evolutionary studies. We conducted one integrated ecological study of Amatique Bay, Guatemala, a major estuary lagoon connected to the Mesoamerican Reef System, and provide novel information for management and conservation of similar systems across the ... -
Getting traceability right, from fish to advanced bio-technological products: a review of legislation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-01)Traceability is a tool used by regulators to manage risk in multiple supply chains, including supply chains of goods derived from genetically modified organisms, human blood, seafood products, toys and hazardous waste. This tool may help support a variety of claims that range from concern for nature to consumer satisfaction and health. This paper examines the consistency of European Union legislation ... -
Polar front associated variation in prokaryotic community structure in Arctic shelf seafloor
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-23)Spatial variations in composition of marine microbial communities and its causes have largely been disclosed in studies comprising rather large environmental and spatial differences. In the present study, we explored if a moderate but temporally permanent climatic division within a contiguous arctic shelf seafloor was traceable in the diversity patterns of its bacterial and archaeal communities. ... -
Transcription factor T-bet in Atlantic salmon: characterization and gene expression in mucosal tissues during Aeromonas salmonicida infection
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-06)The T-box transcription factor T-bet is expressed in a number of hematopoietic cell types in mammals and plays an essential role in the lineage determination of Th1 T-helper cells and is considered as an essential feature for both innate and adaptive immune responses in higher vertebrates. In the present study, we have identified and characterized the full-length Atlantic salmon T-bet cDNA (3502 ... -
Heat treatment increases the protein bioaccessibility in the red seaweed dulse (Palmaria palmata), but not in the brown seaweed winged kelp (Alaria esculenta)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-25)Bioaccessibility of plant proteins has been shown to be inferior to that of proteins of animal origin. Heat treatment has been shown to positively affect this in some plants. The aim of this study was to investigate the effect of heat treatment on bioaccessibility of seaweed proteins. An in vitro gastrointestinal digestion model was used for evaluation of potential effects on the brown seaweed Alaria ... -
