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 ... -
Aktivering av aryl hydrokarbonreseptor (Ahr)-signalveien og lokalisering av ahr genuttrykking i tidlige livsstadier til Atlanterhavstorsk (Gadus morhua) etter eksponering for råolje
(Master thesis, 2019-09-28)Egg og larver av nordøstarktisk (NØA) torsk kan bli truet av eksponering for oljesøl dersom planene om å starte oljeutvinning i dens gyteområder utenfor kysten til Lofoten, Vesterålen og Senja (LoVeSe) realiseres. Råolje ... -
Antibiotic uptake by cultured Atlantic cod leucocytes and effect on intracellular Francisella noatunensis subsp. noatunensis replication
(Peer reviewed; Journal article, 2014-02-04)The granuloma disease caused by Francisella noatunensis subsp. noatunensis in farmed Atlantic cod has not been successfully treated by use of antibacterials, even when antibacterial resistance testing indicates a sufficient ... -
Copepods enhance nutritional status, growth and development in Atlantic cod (Gadus morhua L.) larvae – can we identify the underlying factors?
(Peer reviewed; Journal article, 2015-05-19)The current commercial production protocols for Atlantic cod depend on enriched rotifers and Artemia during first-feeding, but development and growth remain inferior to fish fed natural zooplankton. Two experiments were ... -
Energy dilution with α-cellulose in diets for Atlantic cod (Gadus morhua L.) juveniles - effects on growth, feed intake, liver size and digestibility of nutrients
(Master thesis, 2009-05-03)Atlantic cod (Gadus morhua) is known to grow large livers, especially farmed cod, but commercially, muscle growth is preferred, due to profits. Therefore, main focus in this feeding trial was to achieve lowered liver size, ... -
Enrichment promotes learning in fish
(Peer reviewed; Journal article, 2010-08-18)Captive birds and mammals reared in enriched rearing environments have been shown to behave more flexibly compared to animals reared in impoverished or plain environments. Recent evidence has shown that this is also true ... -
Funksjonell karakterisering av østrogenreseptor α fra atlanterhavstorsk (Gadus morhua); kloning, ligandaktivering og induksjon av østrogenreseptorsignalveien i presisjonskuttede leverskiver
(Master thesis, 2017-11-07)Østrogenreseptor α (ERα) er en steroidreseptor som spiller en viktig rolle i regulering av genuttrykning under kjønnsutvikling og vitellogenese hos teleoster. Den aktiveres naturlig av endogene østrogener, men kan også ... -
In situ hybridisering for deteksjon av cytokrom P450 1A i presisjonskuttede leverskiver (PCLS) fra atlanterhavstorsk (Gadus morhua)
(Master thesis, 2016-06-01)Marine arter og økosystemer blir utsatt for menneskeskapte stoffer fra en rekke ulike kilder. Siden de biologiske effektene for mange av disse stoffene ikke er godt karakterisert er det derfor behov for gode og effektive ... -
Long-term change in a behavioural trait: truncated spawning distribution and demography in Northeast Arctic cod
(Peer reviewed; Journal article, 2015-04)Harvesting may be a potent driver of demographic change and contemporary evolution, which both may have great impacts on animal populations. Research has focused on changes in phenotypic traits that are easily quantifiable ... -
Nodavirus in farmed Atlantic cod Gadus morhua in Norway
(Peer reviewed; Journal article, 2007-09-14)Viral encephalopathy and retinopathy (VER) was diagnosed in 5 to 24 g sized farmed Atlantic cod Gadus morhua kept in sea cages at Parisvatn, Hordaland county, on the west coast of Norway. Moderate mortality (10 to 15%) was ... -
Timing and selectivity of mortality in reared Atlantic cod revealed by otolith analysis
(Peer reviewed; Journal article, 2010-11-03)In juvenile fish production, large samples of known-aged material can be sampled at pre-determined time intervals from the same population. This enables an accurate determination of size-selective mortality by means of ...
