Feeding ecology of Atlantic mackerel (Scomber scombrus) in the Norwegian Sea
(ICES CM documents, Working paper, 2006)Previous studies on Atlantic mackerel (Scomber scombrus) feeding during the highly migratory summer period are scarce. In this study we present detailed diet analyses and investigations of prey selection for Atlantic ... -
Fisheries-Induced Changes in Age and Size at Maturation and Understanding the Potential for Selection-Induced Stock Collapse
(ICES CM documents, Working paper, 2002)Fishing is very likely to create selective pressures inducing adaptive changes in the life histories of harvested stocks. Using field data and adequate statistical methods, such alterations can be demonstrated. However, ... -
Fisheries-induced trends in reaction norms for maturation in North Sea plaice
(ICES CM documents, Working paper, 2002)We analyse the potential of intensive exploitation to have caused evolutionary changes in the age and length at maturation in North Sea plaice Pleuronectes platessa. Such evolutionary change in the onset of maturation ... -
Fourth report of the working group on marine pollution baseline and monitoring studies in the North Atlantic : Charlottenlund, 17-19 May 1978
(ICES CM Documents;1978/E:6, Working paper, 1978) -
A Framework for Communicating Qualities of Indicators
(ICES CM documents, Working paper, 2003)There is a growing focus on ecosystem-based indicators and what qualities they need to satisfy. However, the qualities and the characteristics of the already existing indicators vary substantially. Due to both scientific ... -
Growth differences in juvenile Norwegian spring spawning herring (Clupea harengus L.) related to temperature conditions in the nursery areas
(ICES CM documents, Working paper, 2005)Growth differences in juvenile Norwegian spring spawning herring (Clupea harengus L.) related to temperature conditions in the nursery areas The hatched larvae of Norwegian spring spawning herring are transported to ... -
Harbour seal Phoca vitulina habitat use and interactions with fisheries as explored by a combined GIS and population energetics model
(ICES CM documents, Working paper, 2000) -
How does stochasticity affect evolutionary regime shifts in age and size at maturation?
(ICES CM documents, Working paper, 2006)Fish in many exploited stocks grow faster and mature earlier at either larger or smaller sizes in comparison to pre-exploitation periods. These changes can be driven by both genetic and phenotypic responses. We have shown ... -
How variable is the fecundity within and between cod stocks?
(ICES CM documents, Working paper, 2005)Stock reproductive potential is determined by the number of fish at age, sex ratio, proportion of mature female at age and fecundity. Fecundity data, which are fundamental in estimating egg production are not collected ... -
ICES working group on pollution baseline and monitoring studies in the Oslo commission and ICNAF areas : Report of the sub-group on the feasibility of effects monitoring
(ICES CM Documents;1976/E:44, Working paper, 1976)This report first discusses selected recent literature on the effects of pollutants on marine organisms under six headings - biochemical, morphological, physiological, behavioural, population/community and genetic, and ... -
ICES Workshop on Time Series Data relevant to Eutrophication Ecological Quality Objectives [WKEUT] [11–14 September Tisvildeleje, Denmark]
(ICES CM documents;2006/ACE:07, Working paper, 2006) -
Identifying particularly valuable and vulnerable areas: a key tool for the integrated management plans for the Barents Sea and Norwegian Sea.
(ICES CM documents;2008/E:14, Working paper, 2008)In 2006 Norway implemented an integrated and ecosystem-based management plan for the Barents Sea, and is currently developing a similar plan for the Norwegian sea. Norway aims to have such plans for all sea areas under ... -
IMR status report on the Barents Sea Ecosystem, 2004-2005
(Working paper, 2005) -
In/out-flow of coastal water in Vestfjorden
(ICES CM Documents;1978/C:51, Working paper, 1978)Hydrographic sections in Vestfjorden, Northern Norway, during winter 1977 showed strong horizontal temperature gradients on the west side of the fjord indicating an outflow of cold coastal water. Analysis of sea thermograph ... -
Including climate into the assessment of future fish recruitment, using multiple regression models.
(ICES CM documents, Working paper, 2005)Climate variability has generally not been included in the assessment of fish stocks in the Barents Sea and Norwegian Sea. However, in recent years there has been a focus on implementing climate variability in the assessment ... -
Landscape dynamics and predator-prey interactions in marine environments
(ICES CM documents, Working paper, 2004)In several sub-arctic marine ecosystems of the North Atlantic capelin are the primary prey item for cod, and the trophic interaction between capelin and cod is a central energetic pathway. However, in the North Pacific ... -
Linking tagging technology and molecular genetics to gain insight in the spatial dynamics of two stocks of cod in Northeast Atlantic waters
(ICES CM documents, Working paper, 2006)The Northeast Arctic cod (Gadus morhua L.: NEAC) is thought to be the most abundant cod stock in the North Atlantic, while the catches of the partially co-occurring Norwegian coastal cod (NCC) stocks have dramatically ... -
Marine ecosystems and fish stocks under climate variability and change
(ICES CM Documents;, Working paper, 2006) -
The Mean Sea Level Pressure (MSLP) Gradient across the Denmark Strait as Index for the Oceanographic Conditions in North Icelandic Waters
(ICES CM documents, Working paper, 2002)The oceanographic conditions in Icelandic waters are closely related to atmospheric forcing. In the present paper winter means of the atmospheric sea level pressure gradient across the Denmark Strait are correlated to a ... -
