(Journal article; Peer reviewed, 2010-06-29)Material collected in summer 2004 from the Mid-Atlantic Ridge between Iceland and the Azores with three pelagic trawls was used to estimate relative catchabilities of common fish, cephalopod, decapod, and jellyfish species. ... -
Molecular cloning, characterization and nutritional regulation of key enzymes required for the effective utilization of marine wax esters by Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2010-10)Previous studies had shown that wax ester-rich lipid extracted from calanoid copepods could be a useful alternative to fish oil as a provider of long-chain n-3 polyunsaturated fatty acids in diets for use in salmon ... -
Fluctuating sea-cage environments modify the effects of stocking densities on production and welfare parameters of Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2011-05-21)Stocking densities are commonly used to set limits for the production of fish in sea-cages, yet limited information exists to assess how environmental fluctuations modify the effects of stocking densities on the production ... -

Water quality and microbial community structure in juvenile Atlantic cod (Gadus morhua L.) cultures
(Journal article; Peer reviewed, 2011-06)The effect of water treatment and flow rate on young Atlantic cod juveniles was investigated in a 36-days experiment. Four different flow rates (10, 20, 40, and 70 times the effective tank volume per day) were set up in ... -
Disease interaction and pathogens exchange between wild and farmed fish populations with special reference to Norway
(Journal article; Peer reviewed, 2011-05-21)Norway has the largest salmon-farming industry in the world, an industry that is still growing, and in recent years production of marine species like Atlantic cod has also increased. At the same time, Norway has the world's ... -
Characterisation and expression analysis of the Atlantic halibut (Hippoglossus hippoglossus L.) cytokines: IL-1β, IL-6, IL-11, IL-12β and IFNγ
(Journal article; Peer reviewed, 2011-06-05)Genes encoding the five Atlantic halibut (Hippoglossus hippoglossus L.) cytokines; interleukin (IL)-1β, IL-6, IL-11b, IL-12βc, and interferon (IFN) γ, were cloned and characterised at a molecular level. The genomic ... -
Reduced migratory performance of farmed Atlantic salmon post-smolts from a simulated escape during autumn
(Journal article; Peer reviewed, 2010-11-10)Escape of migratory finfish species from fish farms, such as Atlantic salmon Salmo salar L., offer a challenge when considering the environmental risks of cage culture. The migratory behaviour of groups of cultured salmon ... -
Recapture of cultured salmon following a large-scale escape experiment
(Journal article; Peer reviewed, 2010-10-19)A large-scale escape experiment using 1031 adult Atlantic salmon Salmo salar L. was performed in the Hardangerfjord in western Norway to study the dispersal of escaped salmon, evaluate the effect of a gill-net fishery ... -
Adult recaptures of farmed Atlantic salmon post-smolts allowed to escape during summer
(Journal article; Peer reviewed, 2010-12-21)The influence of time of escape on survival to adulthood was tested in farmed Atlantic salmon Salmo salar smolt and post-smolts. Escape events were simulated in a small fjord in western Norway during and after the natural ... -
Environmental drivers of Atlantic salmon behaviour in sea-cages: a review
(Journal article; Peer reviewed, 2011-02-03)Salmon may sense and respond to a range of environmental variables within sea-cages, including light, temperature, salinity, dissolved oxygen, water currents and certain chemical treatments used during production. Environments ... -

The combined impact of plant-derived dietary ingredients and acute stress on the intestinal arachidonic acid cascade in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2010-03)A study was conducted to assess the effect of substituting high levels of dietary fish oil (FO) and fishmeal (FM) for vegetable oil (VO) and plant protein (PP) on the intestinal arachidonic acid (AA) cascade in the carnivorous ... -
MMP-13 (Matrix MetalloProteinase 13) expression might be an indicator for increased ECM remodeling and early signs of vertebral compression in farmed Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2010-04)Vertebral body compression is a common problem in commercial farming of Atlantic salmon. Although risk factors, such as vaccination and alnutrition, have been identified, the etiology is largely unknown. Histological studies ... -
