Pathogen screening in Semi Closed Containment Systems and open net pens with emphasis on the presence of Tenacibaculum spp. and development of Real Time RT- PCR assays for Tenacibaculum spp.
(Master thesis, 2021-06-07)Tenacibaculosis, caused by Tenacibaculum spp., has been an increasing problem in Norwegian Salmon farming causing reduced fish welfare and significant economic losses. Semi Closed Containment System (SCCS) is a rather new ... -
In-vitro characterization of pancreatic functional units from Cel-MODY mice
(Master thesis, 2021-06-01)The digestive enzyme carboxyl-ester lipase (CEL) is secreted by pancreatic acinar cells into the duodenum where it hydrolyzes dietary fat, cholesteryl esters, and fat-soluble vitamins. To date, two single-base mutations ... -
The Melanocortin System in Atlantic Salmon (Salmo salar L.) and Its Role in Appetite Control
(Journal article; Peer reviewed, 2020-08-21)The melanocortin system is a key neuroendocrine network involved in the control of food intake and energy homeostasis in vertebrates. Within the hypothalamus, the system comprises two main distinct neuronal cell populations ... -
Complexities in commercial scale use of non-invasive controls against parasites in aquaculture
(Doctoral thesis, 2021-06-30)Salmon lice (Lepeophtheirus salmonis) are one of the major challenges faced by the Atlantic salmon (Salmo salar) aquaculture industry. Due to the risk of poor welfare outcomes and high mortality during treatments against ... -
Insects reared on seaweed as novel feed ingredients for Atlantic salmon (Salmo salar) : Investigating the transfer of essential nutrients and undesirable substances along the seaweed-insect-fish food chain
(Doctoral thesis, 2020-12-09)Traditionally, major sources of protein and lipid in aquaculture fish feeds have been fish meal and fish oil. However, fish stocks used for fish meal and fish oil production are fully exploited, therefore prices of these ... -
The pantophysin gene and its relationship with survival in early life stages of Atlantic cod: Pantophysin in Atlantic cod
(Journal article; Peer reviewed, 2020)Genetic markers are widely used in fisheries management around the world. While the genetic structure and markers selected are usually based on samples from the wild, very few controlled experiments have been carried out ... -
Modulation of nutrient composition of black soldier fly (Hermetia illucens) larvae by feeding seaweed-enriched media
(Journal article, 2017-08-24)Black soldier fly (Hermetia illucens) larvae are a promising source of protein and lipid for animal feeds. The nutritional composition of the BSF larvae depend partly on the composition of the feeding medium. The BSF lipid ... -
Tapeworm (Eubothrium sp.) infestation in sea caged Atlantic salmon decreased by lice barrier snorkels during a commercial-scale study
(Journal article, 2021)Reports of infestation by marine parasitic tapeworms (Eubothrium sp.) and an associated growth reduction in Norwegian farmed salmon are on the rise. With few acceptable treatment options available, due to drug resistance ... -
Temporal constraints on reproduction and growth in a seasonal environment
(Doctoral thesis, 2021-06-16)The variety of life forms is one of the most striking phenomena that have stimulated research in evolutionary biology and ecology over recent decades. The crucial role in defining the most characteristic features of living ... -
Sequence tiling as a strategy to map novel genotype-dependent cis-regulation in the HIBCH locus (2q32.2)
(Master thesis, 2021-06-01) -
Introducing the index-based ecological condition assessment framework (IBECA)
(Journal article; Peer reviewed, 2021)Sustainable nature management and ecosystem conservation depends critically on scientifically sound and stakeholder-relevant analytical frameworks for monitoring and assessing ecological condition. Several general frameworks ... -
Innate immune mechanisms in invertebrates: Insights into the Toll pathway, the Imd pathway, and the complement system
(Doctoral thesis, 2021-06-25)The innate immune system is the first line of defense against pathogens. This system is equipped with receptors, named Pattern Recognition Receptors (PRRs), that recognize a broad set of molecules present in pathogens, ... -
Functional dissection of a genetic locus for visceral fat mass (11q23.3)

Immunrespons mot Pasteurella spp. hjå rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.)
(Master thesis, 2021-06-01)Dei siste åra har ein sett ei dramatisk auke i tilfelle pasteurellose i norsk oppdrett av rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.). Sjukdommen førar til redusert fiskevelferd og kan innebere høg ... -
Parasites Found in Pink Salmon (Oncorhynchus gorbuscha) Caught in the Feeding Areas in the Norwegian Sea
(Master thesis, 2021-06-01)The pink salmon (Oncorhynchus gorbuscha) is native to the North Pacific but has repeatedly been introduced to the North Atlantic by Russian researchers since 1956. This has resulted in the establishment of populations in ...
