Changes in the dynamics of the Norwegian mackerel purse seine fishery – does it influence the representativeness of the reference fleet data?
(ICES CM documents;2008 / I:13, Working paper, 2008)The last three years, the peak period and the fishing area of the Norwegian mackerel purse seine fishery has changed considerably due to market situations. The Norwegian reference fleet was established to get better and ... -
Changes in the Norwegian Sea deep water
(ICES CM Documents;1996/O:11, Working paper, 1996)This paper deals with observed changes in the Norwegian Sea Deep Water (NSDW) after the cessation of bottom water formation in the Greenland Sea. Current measurements indicate that the deep water flow from the Greenland ... -
Changes on horse mackerel (Trachurus trachurus) catch distribution in the Northeast Atlantic
(ICES CM Documents;1996/S:26, Working paper, 1996)The distributions of international commercial catch data were mapped by ICES rectangle and quarter from 1983-1994. These indicate a northward expansion of horse mackerel distribution in the Northeast Atlantic since 1987. ... -

Cleaning symbiosis between wrasses (Labridae) and lice infested salmon (Salmo salar) in mariculture
(ICES CM Documents;1988/F:17, Working paper, 1988)Epidemic infestation by the crustacean ectoparasitic salmon lice (Lepeophteirus salmonis) is a major problem in marine salmon farming. Cleaning symbiosis between different labrid species and lice infested salmon is ... -

Climatic changes at the North Sea plateau during 1967 - 1984
(ICES CM Documents;1987/C:17, Working paper, 1987)The average temperature and salinity in the water masses with S> 35.0 in the Utsira and Hanstholmen sections for the periode 1967-1984 is presented. The influence of the mid 1970`s salinity anomaly at the North Sea ... -

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 ... -
Climatic variations in the Barents Sea during the 1970`s

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 ... -
Coastal and fjord resources off Finnmark and Troms counties, Norway, based on the 1992 survey
(ICES CM Documents;1994/G:38, Working paper, 1994)In 1992 an acoustic survey in fjords and shelf areas off Finnmark and Troms, two counties in northern Norway, was made to estimate the total biomass of cod, haddoc, saithe, redfish species and herring to be 876.000 tonnes. ... -
Coastal releases of Atlantic salmon, a new model for salmon ranching in Norway
(ICES CM Documents;1991/M:38, Working paper, 1991)The present project is launched within the frame of a 7 year government funded programme to establish an additional livelihood for the coastal regions. The aim of the study is, through controlled experiments, to find ... -

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 ... -

Codend selectivity of the Danish seine investigated by the trouser trawl method
(ICES CM Documents;1988/B:28, Working paper, 1988)During June 1986 codend selectivity of the Danish seine was measured using both diamond mesh codends and square mesh codends. Comparisons between different codends were made by the trouser trawl method, having two ... -
Coincidence echo statistics
(ICES CM Documents;1994/B:40, Working paper, 1994)Two scatterers at similar range give an echo which may appear to be due to a single scatterer. Methods for determining target strength that depend on resolving single scatterers may fail in this instance. Statistics associated ...
