1H NMR metabolic profiling of cod (Gadus morhua) larvae: potential effects of temperature and diet composition during early developmental stages
(Peer reviewed; Journal article, 2015)Marine aquaculture offers a great source of protein for the increasing human population, and farming of, for example, Atlantic salmon is a global industry. Atlantic cod farming however, is an example of a promising industry ... -
A 24,000-year ancient DNA and pollen record from the Polar Urals reveals temporal dynamics of arctic and boreal plant communities
(Journal article; Peer reviewed, 2020)A 24,000-year record of plant community dynamics, based on pollen and ancient DNA from the sediments (sedaDNA) of Lake Bolshoye Shchuchye in the Polar Ural Mountains, provides detailed information on the flora of the Last ... -
The 474-Kilobase-Pair Complete Genome Sequence of CeV-01B, a Virus Infecting Haptolina (Chrysochromulina) ericina(Prymnesiophyceae)
(Peer reviewed; Journal article, 2015-12-03)We report the complete genome sequence of CeV-01B, a large double-stranded DNA virus infecting the unicellular marine phytoplankton Haptolina (formerly Chrysochromulina) ericina. CeV-01B and its closest relative Phaeocystis ... -
Acacia trees on the cultural landscapes of the Red Sea Hills
(Peer reviewed; Journal article, 2014-07-18)This paper examines interactions between five pastoral nomadic culture groups of the Egyptian and Sudanese Red Sea Hills and the acacia trees Acacia tortilis (Forssk.) Hayne subsp. tortilis and subsp. raddiana growing in ... -
Acoustic attenuation by air bubble in bad weather conditions; a comparison of hull- and keel-mounted transducers
(Master thesis, 2009-08-25)Echo integration in bad weather conditions is problematic due to vessel- and wind-induced air bubble layer that is formed below the hull of a vessel, where acoustic transducers are mounted. The bubbles below the hull ... -
Actin N-terminal acetylation impacts cell adhesion and invasion

Acute effects of gas supersaturation on Atlantic salmon smolt in two Norwegian rivers
(Journal article; Peer reviewed, 2020)Total dissolved gas (TDG) supersaturation downstream of hydropower plants may cause gas bubble disease (GBD) and harmful effects in fish. Little is known about tolerance levels of TDG supersaturation on Atlantic salmon ... -
Adaptation of anemonefish to their host anemones: From Genetics to Physiology
(Doctoral thesis, 2020-02-21)The mutualism between anemonefish and anemones can be studied in terms of permanent or temporary adaptation of fish toward their host anemones. This thesis explores this theme, and aims to test (1) Whether a mutual ... -
Adaptation of unbiased stereological methods to study theeffects of feed composition on the morphometrics of the different layers of the digestive tract of juvenile Atlantic cod (Gadus morhua L.)
(Master thesis, 2004)Juveniles of Atlantic cod (Gadus morhua L.) were fed food, containing different compositions of macro-nutrients (proteins, fat and carbohydrates). The aims of this study were to evaluate the use of unbiased stereology to ... -
Adaptive and plastic variation in growth and maturation of the cutlassfish Trichiurus japonicus in the subtropical Pacific Ocean
(Peer reviewed; Journal article, 2018) -
Adaptive Humoral Immune Response in Lumpfish, Cyclopterus lumpus L.
(Master thesis, 2015-10-05)The lumpfish, Cyclopterus lumpus L. is an emerging and most promising aquaculture fish currently used for a biological control against sea lice in salmonids. However, the lumpfish is prone to a number of bacterial diseases ... -
Advances in herring biology: from simple to complex, coping with plasticity and adaptability
(Peer reviewed; Journal article, 2009)At least two centuries of investigations on herring have been absorbed by scientific journals, and applied and fundamental research has produced groundbreaking concepts in fisheries, population biology, and marine ecology. ... -
Age and growth determination and stock identification using statolith microstructure of Indian squid, Loligo duvauceli
(Master thesis, 2010-05-29)Age and growth and stock identification of Indian squid, Loligo duvauceli were examined by statolith microstructure and morphological measurements. The Indian squid were sampled from the Gulf of Thailand and the Andaman ... -
Age determination of Atlantic halibut (Hippoglossus hippoglossus L.) - Size at age and regional growth differences along the coast of Norway
(Master thesis, 2011-05-25)The traditional method for estimating age of Atlantic halibut (Hippoglossus hippoglossus) is through surface readings. Previous studies have not been compared to find the best practice for surface reading techniques. Based ... -
Aktivering av aryl hydrokarbonreseptor (Ahr)-signalveien og lokalisering av ahr genuttrykking i tidlige livsstadier til Atlanterhavstorsk (Gadus morhua) etter eksponering for råolje
