(Master thesis, 2021-06-01)The Atlantic salmon is one of the most economically important species in modern-day aquaculture. For this reason, a lot of effort has been put into implementation and improvement of breeding programs for this species, ... -
Characterization of genes and gene products influencing carotenoid metabolism in Atlantic salmon
(PhD Thesis;2017:36, Doctoral thesis, 2017)Distinct red flesh color is a unique trait of the fish genera Oncorhynchus, Salvelinus, Salmo and Parahucho. In this thesis we have investigated its molecular basis in Atlantic salmon to better understand how and why it ... -
Does tunnel wash water have an impact on vital rates and displacement of Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in river Årungselva
(Master thesis, 2021)Earlier studies on runoff water from roads and tunnels have demonstrated that such water hold toxic substances that can be harmful to aquatic biota. River Årungselva, which flows into the inner part of Bunnefjorden close ... -
Effects of dietary oxidation status and vitamin E level on performance, fillet quality and robustness to acute stress in Atlantic salmon (Salmo salar L.)
(Master thesis, 2012-05-18)The effects of oxidized dietary lipid and the role of vitamin E on the growth performance, biometric traits, blood parameters, muscle pH and fillet quality of Atlantic salmon (Salmo salar L.) were evaluated after a 79-day ... -
Effects of the hatchery environment on neurobiology and behaviour in Atlantic salmon : implications for stocking
(PhD Thesis;2018:80, Doctoral thesis, 2018)The Atlantic salmon (Salmo salar) is an iconic fish species with a widespread historic abundance, but recent decades have witnessed a dramatic decline in wild stocks due to a variety of anthropogenic factors, especially ... -
Effekten strømbehandling har på tidsforløpet fra slakt til inntredelse av rigor mortis, og påvirkning av kvalitet (væskeslipp) i fileter av Salmo salar
(Master thesis, 2015-03-17)En rekke testforsøk samt to hovedforsøk ble utført på fileter av atlanterhavslaks (Salmo salar) for å observere om strøm kan stimulere en fiskefilet til å inntre raskere i rigor mortis (dødsstivhet, senere referert i ... -
Fillet quality and yield of farmed Atlantic salmon (Salmo salar L.): variation between families, gender differences and the importance of maturation
(Master thesis, 2012-04-27)The aim was to study biometric parameters, yield and fillet quality traits of farmed Atlantic salmon (Salmo salar L.) belonging to the 2008 year class of the breeding nucleus of SalmoBreed AS, Norway. The offspring analyzed ... -
Gene expression of the vitellogenins and the receptors during the annual reproductive cycle
(Master thesis, 2016-08-16)Atlantic salmon belongs to the primitive group of protacanthomorph teleost and has two Vtg genes (VtgAsa and VtgAsb) and two VtgR genes (VtgR1 and VtgR2). The focus of our research was to characterize predicted salmon Vtgs ... -
Gene expression responses to bacterial peptidoglycan in Atlantic salmon (Salmo salar) adipocytes enriched with two levels of omega-3 fatty acids and vitamin E
(Master thesis, 2012-06-01)Adipose tissue is recognized as an active endocrine organ, influencing metabolism, inflammation and immunity in mammals. The size of the visceral adipose tissue in farmed Atlantic salmon has increased due to the exposure ... -
Grading of correlated quality traits for added market value in Atlantic salmon (Salmo salar L.) - A model with example data
(Master thesis, 2010-11-29)The quality of the Atlantic salmon (Salmo salar L.) at the time of harvest affects the economic value and is in addition to body weight generally determined by the body composition and carcass quality traits, such as fillet ... -
The growth of Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) from the river Etneelva, Norway. A comparison of the periods 1976-1982 and 2000-2007.
(Master thesis, 2010-11-12)The populations of Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) are declining in Europe. For both species the key seems to be found in the saltwater stage of their life cycle. Two major changes have occurred ... -
Immune responses in Atlantic salmon (Salmo salar) following vaccination and Salmonid alphavirus challenge
(Doctoral thesis, 2021)Norway has perfect conditions for Atlantic salmon (Salmo salar) production and is one of the largest producers of salmon for food consumption worldwide, but rearing fish at high densities also means that infectious disease ... -
Influence of nutritional factors on muscle development and texture of Atlantic salmon ( Salmo salar L.). In vivo and in vitro studies.
(Master thesis, 2010-11-15)The aim of the present study was to examine the effect of amino acids or bioactive fatty acid on the Atlantic salmon flesh quality with main emphasis on the muscle development and fillets texture by in vivo and in vitro ... -
Innsjøenes betydning som produksjonshabitat for laksesmolt; en undersøkelse av tetthet og vekst av laksunger i Roksdalsvassdraget i Nordland
(Master thesis, 2011-10-14)Flere vassdrag i Nord-Norge har bestander av atlantisk laks (Salmo salar) der ungene utnytter både innsjøer og elver som oppveksthabitat. Roksdalsvassdraget i Nordland er et slikt vassdrag. Tetthetsberegninger og vekststudier ... -
Laksefiske i Norge 2020: Atferd blant aktive fiskere og svenske fiskere som ikke besøkte Norge pga. corona-pandemien
