Long-term movement patterns of coastal cod (Gadus morhua)
(ICES CM Documents;2001/L:18, Working paper, 2001)Movement patterns were studied by means of hydroacustic telemetry along the Norwegian Skagerrak coast. Ultrasonic transmitters was surgically implanted in 10 coastal cod, and released in the same area as they where caught. ... -
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 ... -
Manual for the ICES North Sea Stomach Sampling Project in 1991 [Aberdeen, 8- 10 January, 1991]
(ICES CM Documents;1991/G:3, Working paper, 1991) -
Mapping the migration pattern of schooling fish by use of multi-beam sonar during conventional acoustic surveys
(ICES CM Documents;1994/Mini:9, Working paper, 1994)Information on migration pattern and swimming behaviour of pelagic fish schools in the vicinity of steaming survey vessels has been collected by a multi-beam sonar system connected to an external device for data collection ... -
Marine Habitat Mapping for the Norwegian Sea
(ICES CM documents, Working paper, 2000)An initiative is currently being taken by several Norwegian organizations to obtain funds to intensify ongoing investigations on marine sea-floor mapping off Norway. Led by the Geological Survey of Norway and Institute ... -
Mass-production of cod fry (Gadus morhua L.) in a large basin in western Norway - a new approach
(ICES CM Documents;1984/F:16, Working paper, 1984)In February 1984, the fresh water in a small lake was replaced by seawater pumped from 40 m depth. Four-day old cod larvae were transferred on 11 and 26 April into this seawater basin, which was 5 m above sea level with ... -
The Mean Sea Level Pressure (MSLP) Gradient across the Denmark Strait as Index for the Oceanographic Conditions in North Icelandic Waters
(ICES CM documents, Working paper, 2002)The oceanographic conditions in Icelandic waters are closely related to atmospheric forcing. In the present paper winter means of the atmospheric sea level pressure gradient across the Denmark Strait are correlated to a ... -
Measurement of salinity with a new ultrasonic salinity sensor
(ICES CM Documents;1977/C:21, Working paper, 1977)The paper describes a way of measuring salinity by direct measurements of the fraction of total sound velocity that is dependent of salinity only. Preliminary experiments indicate an obtainable precision of appr. 1/100 ... -
Measurements of Iceland scallop (Chlamys islandica müller) in the Spitzbergen and Bear Island regions
(ICES CM Documents;1986/K:26, Working paper, 1986)A stratified bottom trawl fish survey was carried out in the Spitzbergen and Bear Island regions from 9 September to 5 October 1985. On 30 out of 108 trawl stations, Chlamys islandica were caught as a by-catch, and ... -
Measurements of the primary production and recordings of water transparency in the Norwegian Sea during May - June 1958 : Preliminary Report
(ICES CM Documents;1959/2, Working paper, 1959) -
Measuring the effect of changes in catchability on the variance of marine survey abundance indices
(ICES CM Documents;1992/D:9, Working paper, 1992)The average catch per tow by a research vessel survey is often used as an index of abundance. An estimate of the variance of such indices that is based only on the between station variability in catch may underestimate ... -
Meeting of the ICES Study Group on SKAGEX [Gdynia, Poland, 4- 8 November, 1991]

Migration behaviour of herring along the cold front in the Norwegian Sea in April 1997
(ICES CM Documents;1997/EE:12, Working paper, 1997)The behaviour of Norwegian spring spawning herring when migrating to the feeding areas in the Norwegian Sea in April was mapped by an acoustic survey in 1997. The distribution of herring was recorded by conventional echo ... -
Migration behaviour of Norwegian spring spawning herring when entering the cold front in the Norwegian Sea
(ICES CM Documents;1996/H:13, Working paper, 1996)The distribution of Norwegian spring spawning herring when migrating to the feeding areas in the Norwegian Sea in spring has been mapped by surveys in April1995 and 1996. The schooling behaviour of the herring have been ... -
The migration of Norwegian herring to Icelandic waters and the environmental conditions in May - June 1961 - 1964
(ICES CM Documents;1964/140, Working paper, 1964) -
Migration of western mackerel to the North Sea 1973 - 1988
(ICES CM Documents;1989/H:20, Working paper, 1989)The latest years, it is evident that most of the mackerel present in the North Sea belongs to the Western stock, since the yearly catches by far exceed the presumed size of the North Sea stock. The Norwegian tagging ... -
Migratory behaviour of reared Norwegian coastal cod and north east Arctic cod
(ICES CM Documents;1995/G:11, Working paper, 1995)This paper is based on experiments to test if differences in migratory behaviour of Norwegian coastal cod and north east Arctic cod is related to parental origin or, alternatively, is related to the environmental experienced ... -
Migratory patterns of escaped farmraised Atlantic salmon
(ICES CM Documents;1990/F:55, Working paper, 1990)Simulated escapes of farmed salmon from netpens are done. Migratory behaviour and routes are studied by combining acoustic tagging and standard tagging - release methodology. A prototype of a recapture trap has been ... -
