Biomassekartlegging av Laminaria digitata i Smøla-området
(Fisken og havet, Research report, 2004)The biomass density of Laminaria digitata was examined on a total of 28 stations in the Smøla area (the county of Møre og Romsdalen). The highest abundance of L. digitata was found in the outermost and most wave-exposed ... -
Development of ten microsatellite loci in the marine fish ling (Molva molva)
(Journal article; Peer reviewed, 2009-09)We developed primers for two dinucleotide and eight tetranucleotide microsatellite loci in a marine fish, the ling (Molva molva). All markers were obtained from partial genomic DNA libraries and characterized in 55 unrelated ... -
Development of twelve novel microsatellite loci in the European lobster (Homarus gammarus)
(Journal article; Peer reviewed, 2010-09)We developed twelve novel microsatellite loci 8 primers in the European lobster (Homarus gammarus). All 9 markers were obtained from partial genomic DNA libraries 10 enriched for tetranucleotide repeats and characterized ... -
Esterase variation in herring studied by isoelectric focusing
(ICES CM Documents;1997/AA:1, Working paper, 1997)Few suitable genetic characteristics for studying herring population structure are available, and the main aim of the study reported here has been to reveal traits which display useful genetic variations for application ... -
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 ... -
Kunnskapsstatus leppefisk : Utfordringer i et økende fiskeri
(Fisken og havet;7-2010, Research report, 2010-11-15)Over the past few years there has been a rapid increase in the use of wrasses as cleanerfish for sealice on salmon farms. During 2010, the landed catch of wrasse was 440 tons, more than twice the 2009 catch and nearly ten ... -

New perspectives on fish movement: kernel and GAM smoothers applied to a century of tagging data on coastal Atlantic cod
(Journal article; Peer reviewed, 2008-12-09)Tagging–recovery studies have been used successfully on many occasions, and the data analysed in a variety of ways with respect to fish movement. Here we provide a synoptic account of useful statistical techniques for ... -
North Sea herring population structure revealed by microsatellite analysis
(Journal article; Peer reviewed, 2005-11-21)The Atlantic herring Clupea harengus has played a pivotal role in the formulation of ideas relating to population structuring in marine fishes, yet considerable uncertainty remains as to the extent to which phenotypic ... -
Pelagic occurrence of Greenland halibut (Reinhardtius hippoglossoides) studied by means of vertical longlines
(ICES CM Documents;2004/K:69, Working paper, 2004)In order to calculate reliable survey indices it’s important to know the dynamics of vertical distribution of a fish species. The vertical distribution of Greenland halibut (Reinhardtius hippogolossoides) cannot be studied ... -
Population genetic structure in a deepwater fish Coryphaenoides rupestris: patterns and processes
(Journal article; Peer reviewed, 2012-07-24)We observed significant genetic structure in a widely distributed North Atlantic demersal deepwater fish, the roundnose grenadier Coryphaenoides rupestris (Pisces: Macro - uridae). The overall estimate of genetic ... -
Population structure and historical demography of eastern North Atlantic harbour porpoises inferred through mtDNA sequences
(Journal article; Peer reviewed, 2006-12-07)The harbour porpoise Phocoena phocoena experiences high rates of incidental mortality in commercial fisheries, and in some areas these rates are sufficiently high to justify concern over population sustainability. Given ... -
Population structure of Ammodytes marinus in the Northeast Atlantic
(ICES CM Documents;1996/G:23, Working paper, 1996)Samples of the lesser sandeel species Ammodytes marinus Raitt were collected from Iceland, Denmark, Scotland, the Faeroe Islands and central and northern North Sea, and analysed for frequency distributions of genotypes ... -

Small-scale genetic structure in a marine population in relation to water circulation and egg characteristics
(Journal article; Peer reviewed, 2010-10)Until the last decade it was assumed that most marine species have pronounced gene flow over vast areas, largely because of their potential for dispersal during early life stages. However, recent genetic, modeling, and ...
