Fate of Francisella noatunensis, a pathogen of Atlantic cod Gadus morhua, in blue mussels Mytilus edulis
(Journal article; Peer reviewed, 2012-02-17)
Francisellosis, caused by the bacterium Francisella noatunensis, is one of the most severe diseases affecting farmed cod, and has caused great economic loss for the cod farming industry in Norway. We studied the fate of ...
Environmental regulation of individual depth on a cod spawning ground
(Journal article; Peer reviewed, 2012-12-13)
Fine-scale characteristics of spawning grounds may provide the opportunity for cod Gadus morhua L. to regulate their external environment by adjusting their depth. Ultrasonic telemetry was used to study how the environment ...
Cod and climate variability in the Barents Sea
(Journal article; Peer reviewed, 2001)
Interannual variability of temperature in the Kola section (Barents Sea) and the abundance as 0-group (age 5 mo) and recruits (age 3 yr), spawning stock biomass, and survival of Arcto-Norwegian cod in the Barents Sea were ...
Retention of Coastal Cod Eggs in a Fjord Caused by Interactions between Egg Buoyancy and Circulation Pattern
(Journal article; Peer reviewed, 2011-08-01)
Norwegian coastal cod form a stationary population of Atlantic cod Gadus morhua consisting of several genetically separated subpopulations. A small-scale differentiation in marine populations with pelagic eggs and larvae ...
Acoustic data collected during and between bottom trawl stations: consistency and common trends
(Journal article; Peer reviewed, 2007)
Acoustic data are often collected during bottom trawl surveys. Their use can potentially improve the precision and accuracy of fish abundance estimates if acoustic data collected between trawl stations are consistent with ...
Catchability and the spatial distribution of fishing vessels
(Journal article; Peer reviewed, 2003)
A central problem when using commercial catch per unit effort (CPUE) as an index of fish stock abundance is that fishing vessels search for concentrations of fish. For a given stock abundance, CPUE may become high if ...
Tenacibaculum sp. associated with winter ulcers in sea-reared Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2011-05-09)
Coldwater-associated ulcers, i.e. winter ulcers, in seawater-reared Atlantic salmon Salmo salar L. have been reported in Norway since the late 1980s, and Moritella viscosa has been established as an important factor in ...
B2 protein from betanodavirus is expressed in recently infected but not in chronically infected fish
(Journal article; Peer reviewed, 2009-02-12)
Betanodavirus infects both larvae and juvenile fish and can cause the disease viral encephalopathy and retinopathy (VER). During an acute outbreak of VER, infected individuals display several clinical signs of infection, ...
Dynamics of the Norwegian Skagerrak cod: intuition vs inference
(Journal article; Peer reviewed, 2002-10-04)
Does the midnight sun increase the feeding rate and hence the growth rate of early juvenile Arcto-Norwegian cod Gadus morhua in the Barents Sea?
(Journal article; Peer reviewed, 2000-05-12)
The growth rate of Arcto-Norwegian cod juveniles in the Barents Sea during their first 4 mo of life is about twice that of cod juveniles in areas farther south, such as Georges Bank and the Flemish cap. Cod larvae and ...
