(ICES CM Documents;1996/N:4, Working paper, 1996)Since 1978, and in particular in 1986-1988, large numbers of harp seals Phoca groenlandica have invaded coastal waters of North Norway during winter and spring. After 1988 the harp seal invasions have been restricted to ... -
Recent migration routes of Norwegian spring spawning herring
(ICES CM Documents;1992/H:18, Working paper, 1992)The migration routes of Norwegian spring spawning herring have changed considerably during the last decades. In the 1950s and beginning of the 1960s the stock spawned off the west coast of Norway in late winter, were ... -
Report of the joint Norwegian-Russian acoustic survey on blue whiting, spring 1993
(ICES CM Documents;1993/H:10, Working paper, 1993)In spring 1993 the fourth joint Norwegian-Russian acoustic survey on the blue whiting spawning stock was carried out. The area to the west of The British Isles was covered by two vessels, one operating in the north-south ... -

Report on surveys of the distribution, abundance and migrations of the Norwegian spring-spawning herring, other pelagic fish and the environment of the Norwegian Sea and adjacent waters in late winter, spring and summer of 1997
(ICES CM Documents;1997/Y:4, Working paper, 1997)The distribution and migrations of Norwegian spring spawning herring in the Norwegian Sea in the spring and summer of 1997 were mapped during 11 coordinated surveys carried out by Faroese, Icelandic, Norwegian, Russian ... -
Results of investigations of migration pattern of artificially reared coastal cod (Gadus morhua L.) in western Norway
(ICES CM Documents;1987/F:26, Working paper, 1987)Investigations of the migration pattern have been a central part in an ongoing enhancement study of cod in western Norway. In Sept. - Nov. 1983, 20,947 juvenile, basin-reared cod fry were tagged and released at three sites ... -
Second Report of the EEC - Norwegian Joint Scientific Group on Migration and Area Distribution of Mackerel (western stock) [Brussel, 12- 13 December, 1989]

Spatial migration pattern of deep-sea redfish (Sebastes mentella Travin) of the Norwegian-Barents population from survey data
(ICES CM Documents;2004/K:31, Working paper, 2004)Study of redfish migration by traditional tagging-methods faces great difficulties. The redfish taken onboard a vessel usually prove to be nonviable. A sharp hydrostatic pressure differential is lethal for the redfish ... -
Spawning of Norwegian spring spawning herring (Clupea harengus L.) related to geographical location and population structure
(ICES CM Documents;1997/CC:17, Working paper, 1997)The catch, distribution, and biology were studied in Norwegian spring spawning herring during the spawning season in 1995. Both the spawning time and choice of spawning grounds were influenced by the size and condition ... -

(ICES CM Documents;1994/Mini:12, Working paper, 1994)Cod along the Norwegian coast show great variability in migration. Coastal Cod may be stationary for the whole life while mature Northeast Arctic Cod migrate long distances to reach the feeding areas in the Barents Sea ...
