A quest for management objectives – case study on the Barents Sea Capelin
(ICES CM documents;2008/O:08, Working paper, 2008)The Barents Sea capelin is a short lived arctic pelagic species and a shared Norwegian-Russian stock. Although the management objectives for Barents Sea capelin have not been explicitly stated, the management authorities ... -
Abundance and productivity of the pelagic ecosystem along a transect across the northern Mid Atlantic Ridge in June 2003
(ICES CM documents;2008/C:12, Working paper, 2008)A research cruise was conducted into the Irminger Sea west and southwest of Iceland on the Icelandic vessel Árni Friðriksson, from 4-30 June 2003, investigating redfish, Sebastes mentella, other pelagic fishes, zooplankton, ... -
Americans on the wrong side – the lobster Homarus americanus captured in Norwegian waters
(ICES CM documents, Working paper, 2000)In November 1999, two female lobsters, one with external egg batch, were captured in the common lobster fishery in the Oslo fjord, Norway and reported as possible American lobsters, Homarus americanus, to Bergen Aquarium ... -
The atlantic inflow to the North Sea and the Skagerrak indicated by surface observations
(ICES CM Documents;1978/C:17, Working paper, 1978)By means of surface observations of temperature and salinity along shipping routes across the North Sea it is shown that the Atlantic inflow along the western and southern edge of the Norwegian Channel seems to reach ... -

(ICES CM Documents;2010/Q:27, Working paper, 2010) -
Blue whiting — a key species in the mid-water ecosystems of the north-eastern Atlantic
(ICES CM documents, Working paper, 2002)Blue whiting (Micromesistius poutassou) is a mesopelagic gadoid that is widely distributed in northeastern Atlantic from the Canary Island to Spitsbergen. It is abundant and commercially exploited in the Norwegian Seas, ... -
Climate-induced synchronous regime shifts along environmental and diversity gradients in Baltic Sea sub-systems
(ICES CM documents;2009/G:03, Working paper, 2009) -
Climatic changes in the deep Norwegian coastal waters and Skagerrak 2000-2005 in relation to previous decades
(ICES CM documents, Working paper, 2006) -
Climatic effects filtered through the food web affect the dynamics of Arcto-Norwegian cod
(ICES CM documents, Working paper, 2005)The world's largest cod stock, the Arcto-Norwegian cod (a.k.a. North-East Arctic cod), is heavily influenced by temperature in two ways: First, cod recruitment tends to be high when Barents Sea temperature in the spawning ... -
Distribution of herring (Clupea harengus) and zooplankton in the Norwegian Sea, as determined from generalised additive models
(ICES CM documents, Working paper, 2005)We analyse the variability in the distribution and feeding of the Norwegian spring-spawning herring in the period from 1995 to 2004, using survey data collected throughout the Norwegian Sea each year in May - June. The ... -
Dramatic changes in spawning stock age-structure of Barents Sea cod
(ICES CM documents, Working paper, 2004)Atlantic Cod (Gadus morhua) is one of the commercially most important fish species in the North Atlantic and plays a central role in several ecosystems. Fishing pressure has been heavy over a prolonged period and the ... -

Ecological carrying capacity in shellfish culture Operational models of carrying capacity applied to a Norwegian fjord
(ICES CM documents;2008/H:09, Working paper, 2008)Estimation of production carrying capacity for shellfish culture has become a major focus in research, with operational models applied at culture sites worldwide. Fundamental to these efforts are an understanding of the ... -
An ecosystem modeling approach to predicting cod recruitment
(ICES CM documents, Working paper, 2006)Abstract The NORWECOM ocean model system implemented with the ROMS ocean circulation model has been run to simulate conditions over the last 25 years for the North Atlantic. Modelled time series of volume fluxes, primary ... -
Effects of climate and stocks interactions on the yield of north-east arctic cod. Results from multispecies model run
(ICES CM documents, Working paper, 2000)A conceptual climate dependent multispecies model for stock interactions and harvesting of herring, capelin and cod in the Norwegian Sea-Barents Sea region has been developed. The concept presupposes that good recruitment ... -

Estimation of harp seal pup production in the Greenland Sea using spatial analysis on aerial survey data
(ICES CM documents, Working paper, 2005)From 14 March to 6 April 2002 aerial surveys were carried out in the Greenland Sea packice to assess the pup production of the Greenland Sea population of harp seals Pagophilus groenlandicus. One xed-wing twin-engined ... -
Exploitation as a driving force of life history evolution: methods and empirical analyses
(ICES CM documents, Working paper, 2004)Today, fishing is the dominant source of mortality in most commercially exploited fish stocks. Life-history theory predicts that, under most circumstances, increased mortality at potential ages and sizes at maturation ...
