A preliminary review of the joint investigations on the distribution of herring in the Norwegian and Iceland Seas 1950- 1970
(ICES CM Documents;1996/H:14, Working paper, 1996)The paper reviews the joint international investigation of the distribution of the Atlanto-Scandian herring in relation to temperature during the period prior to the collapse of the stock in the late 1960s. The results ... -
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 ... -

(CES CM Documents;1977/L:19, Working paper, 1977) -
Dissolved oxygen in contrasting estuaries of the Bay of Biscay: effects of temperature, river discharge and chlorophyll a
(Journal article; Peer reviewed, 2010-11-18)The effects of environmental factors on variations of dissolved oxygen (DO) saturation was assessed in 2 estuaries (Bilbao and Urdaibai) in the Bay of Biscay with contrasting hydrography and anthropogenic impact, for the ... -
Effect of the of temperature on development of embryos and hatching eggs of deep sea prawn (Pandalus borealis KRØYER)
(ICES CM Documents;1976/K:36, Working paper, 1976) -
Fecundity and growth of Atlantic cod (Gadus morhua L.) along a latitudinal gradient
(Journal article; Peer reviewed, 2010-05)Some fish species have wide distribution areas that span very different habitats. In this investigation we have studied Atlantic cod (Gadus morhua), which is an example of such a species, to demonstrate how this may have ... -
Growth of 0-group fish in relation to temperature conditions in the Barents Sea during the period 1965- 1989
(ICES CM Documents;1990/G:49, Working paper, 1990)Since 1965 the International 0-group fish survey has been carried out in the Barents Sea during late August and early September. The main purpose is to determine the year-class strength of some commercial fish species ... -
Havforskningsinstituttets termografstasjoner: Hydrografiske normaler og langtidsvariasjoner i norske kystfarvann mellom 1936 og 2000
(Fisken og havet, Research report, 2001)I 1936 etablerte Havforskningsinstituttet, ved Dr. Jens Eggvin, kontinuerlige målinger av temperatur i overflatelaget og måling av saltholdighet i faste posisjoner fra rutegående skip langs kysten fra Oslofjorden til ... -

Indirect climatic forcing of the Barents Sea capelin: a cohort effect
(Journal article; Peer reviewed, 2004-06-08)Planktivorous capelin is a key species in the Barents Sea, being of great importance in the exploitation of plankton production in this subarctic region. However, in years with a successful reproduction of the Norwegian ... -
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 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 ... -
Interannual variations in the liver condition index of cod as an indicator of temperature and feeding conditions in the Barents Sea
(ICES CM Documents;2001/V:31, Working paper, 2001)Background: Northeast Arctic cod, inhabiting the edge of the species area, experience variable environmental conditions and feeding resources, one of the main of them is capelin. Lipids are an important biochemical link ... -
Long-term temperature ternds in Norwegian coastal waters
(ICES CM Documents;1981/C:19, Working paper, 1981)Time series of sea surface temperature at four meteorological stations on the coast of Norway are compared with observations from three fixed oceanographic stations in Norwegian coastal waters. The longest time series at ... -
Ocean temperature oscillations enable reappearance of blue mussels Mytilus edulis in Svalbard after a 1000 year absence
(Journal article; Peer reviewed, 2005-11-21)We report the first observations of settled blue mussels Mytilus edulis L. in the high Arctic archipelago of Svalbard for the first time since the Viking Age. A scattered population was discovered at a single site at the ... -
Paranucleospora theridion (Microsporidia) infection dynamics in farmed Atlantic salmon Salmo salar put to sea in spring and autumn
(Journal article; Peer reviewed, 2012-10-10)The microsporidian Paranucleospora theridion (syn. Desmozoon lepeophtheirii) is a parasite of Atlantic salmon Salmo salar and also a hyperparasite of the salmon louse Lepeophtheirus salmonis. The parasite develops 2 types ... -
Parental migration, climate and thermal exposure of larvae: spawning in southern regions gives Northeast Arctic cod a warm start
(Journal article; Peer reviewed, 2011-10-20)Temporal variability in environmental conditions met by early life stages is considered a key driver of fluctuations in recruitment and abundance of fish stocks. Variability in spawning grounds selected by the parental ... -
