Horizontal transmission of nervous necrosis virus between turbot Scophthalmus maximus and Atlantic cod Gadus morhua using cohabitation challenge
(Journal article; Peer reviewed, 2012-05-15)Experimental horizontal transmission of nervous necrosis virus (NNV) originating from halibut Hippoglossus hippoglossus was studied through cohabitation of intraperitoneally (i.p.) injected fish with uninfected fish for ... -
How can a potential oil pollution affect the recruitment to fish stocks?
(ICES CM Documents;1989/Mini:5, Working paper, 1989)Eggs, larvae and the larvae's first search for food are the most critical stages in a fish life, both to threats from natural causes and pollution. Based on experimental studies of several species of fish eggs, larvae ... -
How does fishing alter marine populations’ and ecosystems’ sensitivity to climate? – An introduction
(ICES CM documents;2009 /F:01, Working paper, 2009)The effects of climate and fishing on marine populations and ecosystems have conventionally been considered separately and it has often been suggested that they should be disentangled from each other. However, exploitation ... -

ICES coordinated acoustic survey of ICES divisions IIIa, IVa, IVb and VIa (North) 2003 Results
(ICES CM Documents;2004/R:32, Working paper, 2004)Six surveys were carried out during late June and July covering most of the continental shelf north of 52°N in the North Sea and to the west of Scotland to a northern limit of 62°N. The eastern edge of the survey area was ... -
Immigration and emigration of cod in the spawning areas of Lofoten and Møre
(ICES CM Documents;1984/G:48, Working paper, 1984)Abundance estimates of the spawning stock of north east Arctic cod have in recent years been given on the basis of acoustic surveys. Migration in and out of the surveyed areas during investigation has been considered as a ... -
Impact of biogeochemical processes and environmental factors on the calcium carbonate saturation state in the Circumpolar Flaw Lead in the Amundsen Gulf, Arctic Ocean
(Journal article; Peer reviewed, 2011-12-30)We report on measurements across an annual cycle of carbon dioxide system parameters in the polar mixed layer (PML) of the circumpolar flaw lead in the Amundsen Gulf, Arctic Ocean. From these and other properties (nitrate, ... -
Impact of grazin from capelin (Mallotus villosus) on zooplankton: a case study in the northern Barents Sea in August 1985
(ICES CM Documents;1991/L:62, Working paper, 1991)The distribution of capelin was mapped in the area east of Hopen. Zooplankton was sampled with Juday net and 1m^2 MOCNESS sampler, and analyzed with respect to hydrography and capelin abundance. The capelin "front" ... -
Importance of heat transport and local air-sea heat fluxes for Barents Sea climate variability
(Journal article; Peer reviewed, 2010-07-22)An isopycnic coordinate ocean model has been used to investigate the importance of different mechanisms on the Barents Sea climate variability for the period 1948–2006 Observed and simulated time series from the Kola Section ... -

Improving the link between science and management: Drawing upon local fishers' experience
(ICES CM Documents;1994/T:20, Working paper, 1994)Norwegian fish stock assessment has not included estimation of coastal and fjord resources until recently. The geographical area varies both in environmental and biological features. Stock assessment is especially difficult ... -

Incorporating experimentally derived estimates of survey trawl catchability into the stock assessment process
(ICES CM Documents;1997/W:5, Working paper, 1997)During the course of the April, 1996, meeting of the Fishing Technology and Fish Behavior Working Group it became clear to many that the methodology for experimentally estimating the catchability of survey trawls might ... -
Individual based spatial models with evolved fish behaviour
(ICES CM Documents;1998/J:16, Working paper, 1998)Due to spatial heterogeneity, the survival and growth of fishes depend upon their habitat. For mobile pelagic fishes, it hence becomes important to analyse the factors responsible for spatial dynamics in order to understand ... -
Infection success of salmon lice related to temperature and implications for regional size of salmon production areas
(ICES CM Documents;2002/T:1, Working paper, 2002)The development rate for salmon lice larvae is highly temperature-dependent. Hence, the time from hatching of nauplii to an infectious copepodid will vary with the natural cycles in the sea. The salmon lice life span is ...
