Influence of different cold storage temperatures during the Rigor mortis phase on fillet contraction and longer-term quality changes of Atlantic cod fillets
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-05-01)Pre rigor produced fillets of Atlantic cod become shorter and more firm than post rigor produced fillets. In pre rigor excised muscle from warm-blooded animals and warm-water adapted fish, cold shortening, extensive contraction during cold storage, is known to occur. The aim of the present work was to study if the extent of fillet shortening in Atlantic cod could be reduced by a slight temperature ... -

Multidisciplinary perspectives on living marine resources in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-20)Many areas in the Arctic are vulnerable to the impacts of climate change. We observe large-scale effects on physical, biological, economic and social parameters, including ice cover, species distributions, economic activity and regional governance frameworks. Arctic living marine resources are affected in various ways. A holistic understanding of these effects requires a multidisciplinary enterprise. ... -
Effect of codend mesh sizes on the size selectivity and exploitation pattern of cocktail shrimp (Trachypenaeus curvirostris) in shrimp trawl fishery of the South China Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-29)This study aims at improving fishery management by testing and comparing the size selectivity and exploitation pattern of diamond-mesh codends, with mesh sizes ranging from 25 to 54 mm, for cocktail shrimp (Trachypenaeus curvirostris) in the South China Sea (SCS). Beginning from 25 mm, the minimum mesh size regulated by the shrimp trawl fishery industry, we investigated how the mesh sizes of ... -
Effect of Codend Design and Postponed Bleeding on Hemoglobin in Cod Fillets Caught by Bottom Trawl in the Barents Sea Demersal Fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-03)Previous studies have reported that cod caught using a newly developed dual sequential codend showed significant reduction in external catch-related damage compared to cod caught by a conventional codend. In this study, it was investigated whether this new codend affects residual blood in cod fillets and/or mitigates the effect of postponed bleeding. Residual blood was assessed by measuring ... -

Electronic monitoring trials on in the tropical tuna purse-seine fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-12-17)The difficulty of ensuring adequate statistical coverage of whole fleets is a challenge for the implementation of observer programmes and may reduce the usefulness of the data they obtain for management purposes. This makes it necessary to find cost-effective alternatives. Electronic monitoring (EM) systems are being used in some fisheries as an alternative or a complement to human observers. The ... -
MyD88 interacts with interferon regulatory factor (IRF) 3 and IRF7 in Atlantic salmon (Salmo salar): transgenic SsMyD88 modulates the IRF-induced type I interferon response and accumulates in aggresomes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011-10-11)Background: MyD88 directly interacts and affects IRF activation in mammals, but no information has been available about lower vertebrates.<p> <p>Results: Transgenic MyD88 interacts with IRF3 and IRF7A/B and modulates the IRF-induced IFN response and accumulates in aggresomes in Atlantic salmon. <p>Conclusion: MyD88 is involved in the regulation of the IRF-induced IFN response in Atlantic ... -

Livslang læring - fra slagord til reform
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-15)Livslang læring er det nye mantraet. Det dukket opp som et slagord for utdanningsreform på 1970-tallet og er i dag noe som alle tilsynelatende er enige om. Men livslang læring har ulike betydninger og begrunnelser. Veien fra slagord til reform har også vært lang. Denne artikkelen gir et tilbakeblikk på den sammensatte bruken av begrepet og oppsummerer de viktigste reformene som har vært gjennomført ... -
Lessons from bright-spots for advancing knowledge exchange at the interface of marine science and policy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-19)Evidence-informed decision-making is in increasing demand given growing pressures on marine environments. A way to facilitate this is by knowledge exchange among marine scientists and decision-makers. While many barriers are reported in the literature, there are also examples whereby research has successfully informed marine decision-making (i.e., ‘bright-spots’). Here, we identify and analyze 25 ... -
Revising the Impact and Prospects of Activity and Ventilation Rate Bio-Loggers for Tracking Welfare and Fish-Environment Interactions in Salmonids and Mediterranean Farmed Fish
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-07)Behavioral parameters are reliable and useful operational welfare indicators that yield information on fish health and welfare status in aquaculture. However, aquatic environment is still constraining for some solutions based on underwater cameras or echo sounder transmitters. Thus, the use of bio-loggers internally or externally attached to sentinel fish emerges as a solution for fish welfare ... -

(Master thesis; Mastergradsoppgave, 2022-05-16)Abstract The Fishing industry play a major role in socio-economic context of Sri Lanka. Even though, there is a significant potential to develop the fishing industry in country, the current economic performances of the industry are not satisfactory due to poor management mechanisms. It is essential to implement sustainable management approaches in order to achieve socio-economic and environmental ... -
An analysis of the “on/off” Barents Sea capelin fishery: Implications for sustainable management of a fluctuating fish stock
(Master thesis; Mastergradsoppgave, 2022-05-15)Managing an unstable fishery is a difficult task. After Barents Sea capelin reached its peak harvest volumes, it shortly after collapsed in 1986, negatively impacting the ecosystem. After its recovery due to increased management efforts, the capelin fishery has seen fluctuating quota volumes and extended periods of closed fishing activity. However, this unstable quota has caused some challenges for ... -
The bigger they are, the faster they fall, implications of size selective fishing on the spawning stock of Pandalus borealis in the Svartnes basin, (Balsfjord, northern Norway) as relates to size, age, growth, and abundance

Som konsekvens av befolkningsveksten vil behovet og etterspørselen for mat øke. Tilstrekkelig produksjon av næringsrik mat til en økende befolkning utført på en bærekraftig måte er en stor global utfordring. Det antas at særlig proteiner vil være et av næringsstoffene det vil være ... -
Kjøpsintensjon og betalingsvilje for blåskjell. Betydningen av produktegenskaper, normer og individuelle trekk
(Master thesis; Mastergradsoppgave, 2022-05-16)Blåskjelloppdrett omtales som noe nytt i Norge, til tross for at det er over 40 år siden det startet. Selv om forbrukere kjøper blåskjell på restaurant, er det fortsatt få forbrukere som har erfaringer med blåskjell. Målet med studien er å undersøke betydningen av produktegenskaper, normer og personlige og individuelle trekk for kjøpsintensjon og betalingsvilje for blåskjell hos norske forbrukere. ...
