A study on the genetic relationship between salmon lice resistance and disease resistance in Atlantic salmon
(Master thesis, 2012-09-20)The aim of this study is to find the genetic relations between resistance to salmon lice and resistance to other diseases. Three groups of Atlantic salmon from 279 full-sib families (offspring of 140 sires and 279 dams, ... -
Aerobic exercise training for improving robustness of Atlantic salmon (Salmo salar)
(PhD Thesis;2012:29, Doctoral thesis, 2012)Exercise training produces a wide range of benefits to fish kept in captivity. Research has shown that among several other parameters, growth, feed efficiency, feed intake and cardiac capacity are improved. In higher ... -
Antarctic krill (Euphausia superba) as a feed ingredient for salmonids with focus on the shell fraction and fluoride
(PhD Thesis;2011:21, Doctoral thesis, 2011)Antarctic krill (Euphausia superba) may be the largest biomass of a single species worldwide and is a promising ingredient for use in fish feeds. Krill have a balanced amino acid profile, and krill lipids are rich in ... -
Compostion and morphology of Atlantic salmon (Salmo salar L.) as affected by dietary oil
(Master thesis, 2013-09-10)A feeding experiment was conducted to examine the effect of diets high or low in rapeseed and additionally the effect of protein supplementation of diets rich in rapeseed oil in feed for farmed Atlantic salmon (Salmo salar ... -
Genetic studies of Nile tilipia (Oreochromis niloticus) for farming in northern Vietnam : growth, survival and cold tolerance in different farm environments
(PhD Thesis;2010:04, Doctoral thesis, 2010)The present work explores genetic parameters for growth, survival and cold tolerance of tilapia in different farm environments in northern Vietnam. The results are important for further development of selective breeding ... -
Genetic variation in the haemoglobin of the Atlantic cod(Gadus morhua) in trans-Atlantic populations
(Master thesis, 2012-10-05)It can be concluded that Val55-Ala62 haplotype predominated in the Greenland, Canadian, Iceland, and Lofoten NEA, Østersjøen Inner while Met55-Lys62 was mainly found in Østersjøen outer and Skagerrak/Kattegat. The Canadian ... -
Long-term effect of dietary tryptophan supplementation on the physiological stress response in Atlantic Salmon (Salmo salar)
(Master thesis, 2013-09-10)Several strategies to reduce stress among fish in aquaculture are currently under development. A biologically conserved feature of the stress response in vertebrates is the role of the brain serotonergic (5-hydroxytryptamine, ... -
Optimizing methods for studies of adipose tissue function in atlantic salmon
(Master thesis, 2013-10-21)Cell culture of adipocytes is a valuable research tool for studies of adipose tissue functions. The first aim of this thesis was to optimize culture conditions for Atlantic salmon primary cells derived from the adipose-derived ... -
Quantitative genetics of traits related to disease resistance and effects of vaccination in Atlantic salmon (Salmo salar)
(PhD Thesis;2011:39, Doctoral thesis, 2011)Disease resistance is of major importance to the fish farming industry as disease outbreaks have negative effects on the industry’s economy, its reputation and on fish welfare. Today, almost all fish in the Norwegian salmon ... -
Stress responsiveness in salmonids : effects on genes, organs, and organisms
(PhD Thesis;2011:06, Doctoral thesis, 2011)Stress is an inescapable burden for fish like for all other animals. For individuals that frequently encounter stressful situations, repeated or prolonged physiological stress responses, can potentially compromise the ... -
Søk etter DNA-variasjon som virker inn på resistens mot infeksiøs pankreasnekrose (IPN) i Atlantisk laks (Salmo salar)
(Master thesis, 2013-08-28) -
The accuracy of genomic prediction for viral nervous necrosis and vibrosis disease resistance in atlantic cod
(Master thesis, 2014-09-18)The objective of this study was to estimate accuracy of genomic prediction for disease resistance to viral nervous necrosis and vibriosis using sparse and genome sequence SNP-data in Atlantic cod. The disease challenge ... -
The growth and development of lettuce, coriander and swiss chard in a cold water aquaponic system optimized for lettuce production
(Master thesis, 2016-11-17)Aquaponic research seemed to be characterized by experiments conducted in warm water systems while experiments in cold water systems were almost non-existent per August 2016. The main aim of this thesis was therefore to ... -
Variation at early life stages of Atlantic salmon : relationships between emergence time and stress coping styles
(PhD Thesis;2011:08, Doctoral thesis, 2011)Captive fish are exposed to a variety of stressful situations, which can affect growth rates and promote diseases. Identification and selection for stress resistant fish at early stages of the production cycle could be ...
