Changes in plasma and liver glutathione levels in Atlantic salmon Salmo salar suffering from infectious salmon anemia (ISA)
(Journal article; Peer reviewed, 1992-10-08)The levels of reduced glutathione (GSH) in plasma and liver in healthy Atlantic salmon Salmo salar and salmon suffering from infectious salmon anaemia (ISA) were measured using high-performance liquid chromatography (HPLC). ... -
Coastal salmon farms attract large and persistent aggregations of wild fish: an ecosystem effect
(Journal article; Peer reviewed, 2009-06-18)Coastal aquaculture is a globally expanding enterprise. Currently, 1200 salmon farms operate in coastal Norway, yet their capacity to aggregate and subsequently modify wild fish distributions is poorly known. Aggregations ... -
Coho salmon (Oncorhynchus kisutch) transgenic for a growth hormone gene construct exhibit increased rates of muscle hyperplasia and detectable levels of differential gene expression
(Journal article; Peer reviewed, 2000)Transgenic coho salmon (Oncorhynchus kisutch) containing a growth hormone gene construct were compared with nontransgenic coho salmon in terms of gross anatomy, muscle cellularity, muscle enzyme activity, and differential gene ... -
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 ... -
Detection of a nodavirus-like agent in heart tissue from reared Atlantic salmon Salmo salar suffering from cardiac myopathy syndrome (CMS)
(Journal article; Peer reviewed, 1997-05-22)The present study shows that a nodavirus-like agent is associated with the lesions of cardiac myopathy syndrome (CMS), a disease of unknown etiology which affects reared adult Atlantic salmon Salmo salar. In archive ... -
Determination of buoyant density and sensitivity to chloroform and freon for the etiological agent of infectious salmon anaemia
(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, ... -
An effective method for the recapture of escaped farmed salmon
(Journal article; Peer reviewed, 2011-04-04)The search for effective strategies to prevent and mitigate accidental releases of aquaculture fishes is on-going. To test a new recapture strategy and evaluate the individual dispersal behaviour of escaped farmed Atlantic ... -
Effects of water temperature on protein synthesis and protein growth in juvenile Atlantic wolffish (Anarhichas lupus)
(Journal article; Peer reviewed, 1999)The effects of water temperature (5, 8, 11, and 14°C) on the fractional rate (percent per day) of protein consumption (kr) and on white muscle and whole-body fractional rates of protein synthesis (ks), protein growth ... -
Efficacy of orally administered oxolinic acid and Vetoquinol, an oxolinic acid ester, for the treatment furunculosis in Atlantic salmon Salmo salar held seawater
(Journal article; Peer reviewed, 1999-06-23)This study was performed to determine the efficacy of orally administered oxolinic acid and Vetoquinol, an oxolinic acid ester, in the treatment of experimental induced furunculosis in Atlantic salmon Salmo salar held in ... -
Feeding preference of recaptured Atlantic salmon Salmo salar following simulated escape from fish pens during autumn
(Journal article; Peer reviewed, 2010-12-21)Escapes of farmed fish from coastal farms around the world are believed to have genetic and ecological consequences for wild fish populations. Each year there are numerous escapes of adult farmed Atlantic salmon Salmo ... -
Major histocompatibility complex (MHC) variation and susceptibility to the sea louse Lepeophtheirus salmonis in Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2007-06-07)The relationship between genetic variation in major histocompatibility complex (MHC) Class I and II genes and susceptibility to sea lice Lepeophtheirus salmonis (Krøyer) in Atlantic salmon Salmo salar (L.) was studied ... -
Osmotic cataract causes reduced vision in wild Atlantic salmon postsmolts
(Journal article; Peer reviewed, 2003-07-08)Osmotic cataracts were diagnosed in all of 191 Atlantic salmon Salmo salar L. postsmolts caught during 8 trawl hauls on the western side of the Vøringsplateau, Norwegian Sea, in June 2001. The changes varied from a hazy ... -
Patterns of Ichthyobodo necator sensu stricto infections on hatchery-reared Atlantic salmon Salmo salar in Norway
(Journal article; Peer reviewed, 2010-02-17)Infection patterns with ectoparasitic flagellates belonging to the genus Ichthyobodo were studied in an Atlantic salmon Salmo salar (L.) hatchery in western Norway during an 11 mo period, from eyed eggs to smoltification. ... -
Temporal synchrony and variation in abundance of Atlantic salmon (Salmo salar) in two subarctic Barents Sea rivers: influence of oceanic conditions
(Journal article; Peer reviewed, 2004)Long-term variation in Atlantic salmon (Salmo salar) stocks was analyzed in two Barents Sea rivers, the Teno and Näätämöjoki, that represent the northernmost distribution area of the species. In contrast to most of the ... -
