Hermod, a single species model for the Norwegian spring spawning herring stock
(ICES CM Documents;1994/H:11, Working paper, 1994)HERMOD is a model for the population dynamics and migration of the Norwegian Spring spawning herring that is being developed with the double purpose of being an independent single species model and of being integrated ... -

Herring larvae (Clupea harengus) investigations in the Skagerrak area, December 1987 to March 1988. A preliminary report
(ICES CM Documents;1988/H:20, Working paper, 1988)From December 1987 to March 1988 two transects, Torungen - Hirtshals and Oksøy - Hanstholm, were performed once a month for sampling of herring larvae. The gear used was a 9 feet Isaac-Kid Midwater trawl sampling in the ... -
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 ... -
The hydrographical background for regional differences in phytoplankton abundance and specific composition within the Hardangerfjord area

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 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" ... -
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 ... -
Influence of climate on recruitment and migration of fish stocks in the North Sea
(ICES CM Documents;1991/H:12, Working paper, 1991)For several decades one of the prime targets within fishery science has been to be able to understand and explain the great variability in the success of survival from egg to mature fish. One of the reasons why such effort ... -
Influence of sea temperature on herring distribution and migration in the Norwegian Sea in April 1997
(ICES CM Documents;1999/M:3, Working paper, 1999)After spawning at the west coast of Norway, the Norwegian spring spawning herring migrates northwestwards into the Norwegian Sea to feed in early April. The herring enters areas with distinct oceanographic features both ... -
