Characterisation of the capsid protein gene from a nodavirus strain affecting the Atlantic halibut Hippoglossus hippoglossus and design of an optimal reverse-transcriptase polymerase chain reaction (RT-PCR) detection assay
(Journal article; Peer reviewed, 2000-01-14)1349 nucleotide fragment of the RNA2 from a nodavirus affecting Atlantic halibut Hippoglossus hippoglossus was characterised and the nuclotide sequence (accession no, AJ245641) was employed to develop an optimal ... -
Concentrations of iron, copper, zinc and selenium in liver of salmon Salmo salar infected with Vibrio salmonicida
(Journal article; Peer reviewed, 1992-02-17)Lethal infections with Vibrio salmonicida result in a significant reduction in liver concentrations of iron, copper, and selenium expressed as mg kg-1 wet wt liver. Infections also increase liver weight as the hepatic ... -

(Journal article; Peer reviewed, 1993-04-29)Plasma was collected from Atlantic salmon Salmo salar with acute infectious salmon anaemia (ISA) and used to challenge Atlantic salmon parr by intraperitoneal injection. Treatment of plasma with the lipid solvent, chloroform, ... -
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 ... -
Diseases of farmed Atlantic salmon Salmo salar associated with infections by the microsporidian Paranucleospora theridion
(Journal article; Peer reviewed, 2011-03-16)The microsporidian Paranucleospora theridion was discovered in Atlantic salmon Salmo salar suffering from proliferative gill disease in a marine farm in western Norway in 2008. The parasite develops in cells of the ... -
The dual myths of the healthy wild fish and the unhealthy farmed fish
(Journal article; Peer reviewed, 2007-05-04)Although diseases, suffering and death have always been recognized as intrinsic parts of life as far as humans are concerned, it seems that many people tend to disregard these factors when it comes to animals. In particular, ... -
Efficacy of orally administered flumequine in the treatment of vibriosis caused by Listonella anguillarum in Atlantic cod Gadus morhua
(Journal article; Peer reviewed, 2005-11-09)The efficacy of orally administered flumequine in the treatment of experimentally induced vibriosis in Atlantic cod Gadus morhua was investigated. Cod (mean ± SD, 120 ± 30 g) were randomly distributed to twelve tanks and ... -
