(Journal article; Peer reviewed, 2021)Innleiing: Ei ordning der personar med hemokromatose kan bli blodgivarar om det ikkje ligg føre andre hindringar, vil vere bra både for dei personane det gjeld og for blodforsyninga. I Helse Førde har ei slik ordning vore ... -
Physicochemical and functional properties of rainbow trout (Oncorhynchus mykiss) hydrolysate
(Peer reviewed; Journal article, 2023)Due to the continuous growth of the world population, there is an urgent need to find sustainable sources of high-quality protein. Fish side streams rich in essential nutrients and accounting for 60–70% of the whole fish, ... -
Praksisstudienes omfang og organisering i bioingeniørutdanningen
(Peer reviewed; Journal article, 2022)Siden 2005 har omfang og innhold i bioingeniørutdanningen vært definert av en nasjonal rammeplan for å sikre likeverdig sluttkompetanse for alle kandidater. Fra 2019 ble en ny forskrift om nasjonale retningslinjer fastsatt. ... -
Predator–prey interactions in the Arctic: DNA metabarcoding reveals that nestling diet of snow buntings reflects arthropod seasonality
(Peer reviewed; Journal article, 2023)Tundra arthropods are of considerable ecological importance as a seasonal food source for many arctic-breeding birds. Dietary composition and food preferences are rarely known, complicating assessments of ecological ... -
Prevalence and Diversity among Anaplasma phagocytophilum Strains Originating from Ixodes ricinus Ticks from Northwest Norway
(Journal article; Peer reviewed, 2014)The tick-borne pathogen Anaplasma phagocytophilum causes great concern for livestock farmers. Tick-borne Fever is a widespread disease in Norway, and antibodies have been produced amongst sheep, roe deer, red deer, and ... -
Quality and Shelf Life of Liver of Farmed Cod (Gadus morhua)
(Journal article; Peer reviewed, 2016)Livers of Atlantic cod (Gadus morhua) are traditionally used in cod liver oil production or consumed cooked or canned. The farming of cod is a relatively new industry in Norway. The aim of this study was to determine quality ... -
Quantifying environmental impacts of cleaner fish used as sea lice treatments in salmon aquaculture with life cycle assessment
(Peer reviewed; Journal article, 2021)Increasing pressure of sea lice, development of multi‐resistance to chemotherapeutants, and alternative delousing strategies have been raising concerns about the environmental impacts of salmon farming. Ectoparasitic sea ... -
Rainbow Trout (Oncorhynchus mykiss) as Source of Multifunctional Peptides with Antioxidant, ACE and DPP-IV Inhibitory Activities
(Peer reviewed; Journal article, 2023)The present study aimed at characterizing the possible biological activities of the multifunctional low molecular weight fractions (<3 kDa) peptides isolated from rainbow trout (Oncorhynchus mykiss) obtained by enzymatic ... -
Replacement of refined sugar by natural sweeteners: focus on potential health benefits
(Peer reviewed; Journal article, 2022)Refined sugar is a processed product containing 99% sucrose, which is obtained from sugarcane (70%) or sugar beet (30%). In modern societies, sugar continues to play a significant role in the diet, recognised not only for ... -

Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Journal article; Peer reviewed, 2019)Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ... -
A salty start: Brackish water start-up as a microbial management strategy for nitrifying bioreactors with variable salinity
(Peer reviewed; Journal article, 2020)Nitrifying biofilms developed in brackish water are reported to be more robust to salinity changes than freshwater biofilms. This makes them a promising strategy for water treatment systems with variable salinity, such as ... -
Sampling time for different matrices in stress assessment of farmed Atlantic salmon post-smolt
(Journal article; Peer reviewed, 2024)The sustainability of commercial aquaculture production depends critically on prioritizing fish welfare management. Besides monitoring welfare parameters such as fish behaviour and water quality, fish stress level can also ... -
Seeding as a start-up strategy for improving the acclimation of freshwater nitrifying bioreactors to salinity stress
(Peer reviewed; Journal article, 2021)Recirculating aquaculture systems (RAS) for anadromous fish such as salmonids often require salinity changes during the production cycle. However, high or variable salinity can disrupt the biological nitrification process, ... -
Sensory and Physicochemical Quality Characteristics of Haddock Fish Cake Enriched with Atlantic Mackerel
(Peer reviewed; Journal article, 2021)Research background. It is desirable to increase the consumption of pelagic fish rich in long-chain omega-3 fatty acids. Partial replacement of traditionally used white fish species by pelagic fish will increase the content ... -
Study of the influence of pulsed electric field pre-treatment on quality parameters of sea bass during brine salting
