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 ... -

Morphological update on Calycina marina (Pezizellaceae, Helotiales, Leotiomycetes), a new combination for Laetinaevia marina
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-05)Laetinaevia marina is a frequent ascomycetous fungus that is widely distributed on the seashores of Scandinavia and Great Britain. It grows on fronds of Fucales (Phaeophyceae) that are washed ashore and lie decaying at the high tide mark or further up on the beach. It is one of the few described marine discomycetes. In the current generic concept it is regarded as a member of Naevioideae ... -
Climate change alters the structure of arctic marine food webs due to poleward shifts of boreal generalists
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-02)Climate-driven poleward shifts, leading to changes in species composition and relative abundances, have been recently documented in the Arctic. Among the fastest moving species are boreal generalist fish which are expected to affect arctic marine food web structure and ecosystem functioning substantially. Here, we address structural changes at the food web level induced by poleward shifts via ... -
Stubborn fuel tax concessions: The case of fisheries in Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-11-22)In the context of the abolition of traditional subsidies, this paper discusses the persistence of the major remaining subsidy scheme in Norwegian fisheries: exemption from fuel taxes. This reimbursement scheme stems from the late1980s, and has persisted since then under different governments. This paper gives the background to this support against theoretical predictions of the subsidy's effects on ... -
Kvalitetsforbedring og miljøgevinster i norsk villfisksektor – Kvalitetsforbedring i fangstoperasjoner. Sluttrapport
(Research report; Forskningsrapport, 2013-09-13)Gjennom erfaring, kunnskapsutvikling og effektiv forvaltning er viktige fiskebestander nå i godt hold og kvotene er økende. Utfordringen er å utnytte den gunstige ressurssituasjonen til å skape produkter som har høy verdi for konsumentene og god lønnsomhet for næringsaktørene. Nøkkelen ligger i å forbedre og stabilisere kvaliteten på råvarene og sikre en optimal leveringsdyktighet slik at råvarenes ... -
Verktøy for å måle fiskekvalitet - basert på forbrukernes oppfatning (Fase 1 – Forprosjekt). Sluttrapport
(Research report; Forskningsrapport, 2014-10-16)Ved å ha et enkelt verktøy til bruk ved vurdering av kvalitet på fisk i disk kan man sikre at fisk som tilbys forbrukerne har god kvalitet. Det er imidlertid vanskelig å måle fiskekvalitet. Samtidig er det behov for et verktøy for å evaluere kvaliteten på fisken som omsettes. Butikkansatte har behov for å vurdere om fisken holder god nok kvalitet ved mottak og når den skal legges i disken. Mattilsynet ... -
Interkommunale planleggingsprosesser – et bedre verktøy for lokalitetstilgang
(Research report; Forskningsrapport, 2014-10-07)Interkommunalt samarbeid i sjø er relativt nytt i forhold til interkommunalt samarbeid på andre områder. Det er likevel klart at mange kommuner, særlig små distriktskommuner mangler eller har liten plankompetanse og derfor kan ha stor nytte av samarbeid på plansiden. En utfordring med interkommunal planlegging er imidlertid spørsmålet om kommunal styring. For politisk ledelse i kommunen vil det ofte ... -
Rettslig rammeverk for norsk havbruksnæring - Kartlegging av dagens status
(Research report; Forskningsrapport, 2015-06-12)Ambisjoner om videre vekst i norsk havbruksnæring har vært hyppig uttalt, både av næringen selv, og av skiftende regjeringer. Sentralt er at næringen skal gis muligheten til vekst, så lenge det skjer innenfor miljømessige bærekraftige rammer. Dette kan betraktes som en politisk målsetting for norsk havbruksnæring. Men næringens muligheter for vekst avgjøres ikke av politiske målsettinger alene. Andre ... -
Omega-3 Fatty Acids and Cardiovascular Diseases: Effects, Mechanisms and Dietary Relevance
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-18)ω-3 fatty acids (n-3 FA) have, since the 1970s, been associated with beneficial health effects. They are, however, prone to lipid peroxidation due to their many double bonds. Lipid peroxidation is a process that may lead to increased oxidative stress, a condition associated with adverse health effects. Recently, conflicting evidence regarding the health benefits of intake of n-3 from seafood or ... -
From controversy to dialog in aquaculture
(Research report; Forskningsrapport, 2015-07)The Norwegian government has great ambitions for growth and development in the Norwegian aquaculture industry. At the same time, the aquaculture industry also encounters significant opposition by different stakeholders and is undoubtedly controversial. The aquaculture industry contributes to regional and social development in the Arctic, and supplies highly demanded seafood. On the other hand, the ... -
Hva begrenser tilgangen på sjøareal til havbruksnæringen?
(Research report; Forskningsrapport, 2014-08-13)Prosjektet har hovedfokus på havbruksnæringens lokalitetstilgang sett i lys av økt arealbehov ut fra havbruknæringens ønske om vekst. Denne veksten er ikke uproblematisk, for bruk av kystsonen utfordres av mange interesser og brukerere. De siste årene har bærekraftig utvikling av næringen hatt sterkt fokus, hvor klare miljøutfordringer relatert til påvirkning av villaks, luseproblematikk, forurensing, ... -
Results based management in fisheries: Delegating responsibility to resource users
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-10-31)While the notion of results based management has been devoted recent attention in the context of reforming European fisheries management, it remains unclear what it entails. A conceptual model of results based management in fisheries is proposed as a way for public authorities to delegate specific management and documentation responsibilities to resource users. The model comprises three ... -
A deliberative approach to valuation and precautionary management of cold water corals in Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-17)This paper explores management challenges in relation to human impacts on cold water corals (CWC) in Norway. CWC are a slow growing organism about which there is uncertainty regarding distribution and values. We discuss area closures to protect this environmental public good against destructive fishing practices. Focus groups were combined with questionnaires to inform precautionary management ... -
