Acoustic abundance estimation of the stock of Norwegian spring spawning herring, winter 1995- 1996
(ICES CM Documents;1996/H:33, Working paper, 1996)Standard echo integration methodology has been applied to the stock of Norwegian spring spawning herring (Clupea harengus) wintering in the Ofotfjord-Tysfjord-Vestfjord system during late autumn 1995 and early winter ... -

Application of Coded Wire Tagging Technology in Pacific Herring to Investigate Stock Structure and Migration
(ICES CM documents, Working paper, 2001)Tagging of Pacific herring in British Columbia has a long history dating to the mid-1930s but uncertainty in tag recovery locations and low tag return rates limited the utility of these studies. Currently, a larger and ... -
Assessment of the North-East Arctic and North Sea Stocks of Saithe Taking Into Account Migration
(ICES CM Documents;1981/G:36, Working paper, 1981)Tagging experiments have shown that there is a substantial migration of young saithe from the Norwegian coast north of 62°N to the North Sea. Assessments of the North-East Arctic and North Sea Stocks of saithe were made ... -
Atlantic salmon populations invaded by farmed escapees: quantifying genetic introgression with a Bayesian approach and SNPs
(Journal article; Peer reviewed, 2013-08-23)Background Many native Atlantic salmon populations have been invaded by domesticated escapees for three decades or longer. However, thus far, the cumulative level of gene-flow that has occurred from farmed to wild salmon ... -
Behavioural rhythm of cod during migration in the Barents Sea
(ICES CM Documents;2000/K:34, Working paper, 2000)To assess fish abundance by direct methods and to understand and model species interaction, it is important to have proper knowledge about behavioural patterns. Patterns in vertical distribution might strongly affect ... -
Comparison of Northeast Atlantic mackerel (Scomber scombrus) distribution patterns in the Norwegian Sea using lidar, sonar, and trawl
(ICES CM documents, Working paper, 2003)In July 2002 the Institute of Marine Research (IMR), Bergen mapped the distribution and density of mackerel in the Norwegian Sea using lidar, sonar and trawl. A major objective was to test the efficiency of the lidar as ... -

Fish migration in oscillating stratified water masses
(ICES CM documents, Working paper, 2006)Abstract Time series records from data storage tag (DST) attached on Northeast Arctic cod (Gadus morhua L.) and Greenland halibut (Reinhardtius hippoglossoides) are investigated in connection with hydrodynamic and ... -
Genetic mixed-stock analysis of Atlantic herring populations in a mixed feeding area
(Journal article; Peer reviewed, 2011-12-05)Determining spatio-temporal distributions of fish populations is of interest to marine ecology, in general, and to fisheries science in particular. Genetic mixed-stock analysis is routinely applied in several anadromous ... -
Getting fat in a hurry: food consumption during the feeding migration of NSS herring
(ICES CM Documents;2004/K:64, Working paper, 2004)The Norwegian spring-spawning (NSS) herring Clupea harengus inhabits a seasonal environment where food is abundant only during a short period of the year. During that period NSS herring store energy for metabolic ... -

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 ... -
A length-based hypothesis for feeding migrations in pelagic fish
(Journal article; Peer reviewed, 1999)We evaluated the costs and benefits of long-distance horizontal migration by pelagic planktivores, Atlantic herring (Clupea harengus), blue whiting (Micromesistius poutassou), mackerel (Scomber scombrus), and capelin (Mallotus ... -

Migration of Antarctic Minke Whales to the Arctic
(Journal article; Peer reviewed, 2010-12-22)The Antarctic minke whale (Balaenoptera bonaerensis), and the common minke whale found in the North Atlantic (Balaenoptera acutorostrata acutorostrata), undertake synchronized seasonal migrations to feeding areas at their ... -
Migration patterns in Norwegian spring-spawning herring: why young fish swim away from the wintering area in late summer
(Journal article; Peer reviewed, 2003-03-04)Norwegian spring-spawning herring Clupea harengus make extensive feeding migrations in the Norwegian Sea during summer. At the end of the feeding season herring may meet conflicting demands between moving to areas with ...
