Betyr en økning i gytebestanden i dag at bestanden av norsk-arktisk torsk vil øke fremover?
(Havforskningsnytt, Working paper, 2002) -
Bio-physical properties of Norwegian coastal cod eggs
(ICES CM documents;2009/C:11, Working paper, 2009)Vertical distribution of fish eggs and larvae is a key factor for transport and retention of the offspring, and for problems linked to mixing/separation between populations, and hence for mechanism maintaining genetic ... -
Bioaccumulation of contaminants in pelagic organisms, caged blue mussels and cod
(ICES CM Documents;2002/X:4, Working paper, 2002)This short paper will present some preliminary results from the chemistry program of the BECPELAG Workshop. During seven research cruises in 2001 carried out as part of the workshop, pelagic organisms were collected for ... -
Biological reference points for north-east Arctic cod and haddock
(ICES CM Documents;1989/G:29, Working paper, 1989)It has been suggested by ACFM that Fmed might be preferable to Fmax as a biological reference point for the North-East Arctic cod. However, the Fmed level of more than twice Fmax appeared high, and it was known to have ... -
Body condition and evolution of maturation of Atlantic cod in Newfoundland
(ICES CM documents, Working paper, 2006)Atlantic cod (Gadus morhua, L.) stocks off Newfoundland and Labrador underwent severe depletions that started in the late 1980s and led to moratoria in the early 1990s. Fisheries closures are still applied in most of the ... -
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 ... -
Changes in acoustic abundance - a signal indicatior for stock dynamics for cod (Gadus morhua)
(ICES CM documents, Working paper, 1999)To be able to take the proper and timely management actions, it is crucial to reliably defect major changes in trends of fish stock abundance. For the assessment of Northeast Arctic cod, the Norwegian bottom trawl survey ... -
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 ... -
A closed life-cycle model for Northeast Arctic cod
(ICES CM documents, Working paper, 2004)For Northeast Arctic cod (Gadus morhua), there is much knowledge available concerning the main population dynamics processes (growth, maturation, fecundity, recruitment, natural mortality, fishing mortality). This knowledge ... -
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 ... -
Cod fish otoliths: information storage structures. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)The otoliths of cod fish may have incorporated within their structural and chemical components a large amount of lifehistory information. This information may be revealed when appropriate analytical methods are utilized. ... -
Cod in a changing climate Match-mismatch and Threshold for the North Sea cod recruitment
(ICES CM documents;2005 / AA:01, Working paper, 2005)Climatic changes are disrupting otherwise tight trophic interactions between predator and prey. Most of the earlier studies have primarily focused on the temporal dimension of the relationship in the framework of the ... -
Cod populations: Preliminary results in the Lofoten area

Cod, haddock, saithe, herring, and capelin in the Barents Sea and adjacent waters: a review of the biological value of the area
(Journal article; Peer reviewed, 2009-10-09)Cod, haddock, saithe, herring, and capelin are the most important fish species in the Barents Sea and adjacent waters. Ecosystem-based management requires species-specific knowledge of the biological value and vulnerability ... -

Combining hydrographical particles-tracking models with spatial analyses to evaluate spatial dynamics of cod larvae and 0-group in the Barents Sea
(ICES CM Documents;2009/C:06, Working paper, 2009)Recruitment ecology of cod has been an important focus within the framework of GLOBEC. A large part of this work focused on understanding the spatiotemporal component of cod populations. For the early pelagic life stages, ... -
Comparison of tags used on arctic cod
(ICES CM Documents;1959/80, Working paper, 1959) -
Comparison of the effects of forced errors in survey data between an age and an age-and-length structured model of Northeast Arctic Cod
(ICES CM documents, Working paper, 2004)It is known that many fisheries data sets contain several different sources of error. It is likely that models with different structures will, in general, be affected in different ways by these errors. It is therefore ... -
The concept of fecundity regulation in plaice (Pleuronectes platessa) tested on three Irish Sea spawning populations
(Journal article; Peer reviewed, 2007)The fecundity of European plaice (Pleuronectes platessa) in the Irish Sea between 2000 and 2004 was estimated during the spawning season for fish in the three main spawning areas (Liverpool Bay, the Cumbrian coast, and the ...
