Linking behavioural ecology and oceanography: larval behaviour determines growth, mortality and dispersal
(Journal article; Peer reviewed, 2007-10-11)Highly resolved general circulation models (GCMs) now generate realistic flow fields, and have revealed how sensitive larval drift routes are to vertical positioning in the water column. Sensible representation of behavioural ... -
Live and frozen freshwater zooplankton as alternative startfeeding diets for Atlantic salmon in trays
(ICES CM Documents;1985/F:15, Working paper, 1985)Six groups of Atlantic salmon (Salmo salar) fry were starfed with frozen Daphnia longispina, standard start food type EWOS or water with natural content of live zooplankton drained from the littoral zone in a coastal ... -
Liver energy, atresia and oocyte stage influence fecundity regulation in Northeast Arctic cod
(Journal article; Peer reviewed, 2010-04-08)Marine ecosystems are changing; global warming-induced increases in water temperatures and fishing have caused truncated age structures and small sizes at maturity in many stocks. This may affect both populations’ total ... -
Long rough dab (Hippoglossoides platessoides) of the Barents Sea and Svalbard area: ecology and resource evaluation
(ICES CM Documents;1994/O:8, Working paper, 1994)Based on data from Norwegian and Russian bottom trawl surveys in the years 1988-1993, the paper considers distribution, population structure, growth and reproduction of long rough dab (Hippoglossoides platessoides) of ... -
Long-term changes in age at sexual maturity of the northeast Arctic cod (Gadus morhua L.)
(ICES CM Documents;1988/G:42, Working paper, 1988)Maturity ogives of the Northeast Arctic cod for the year classes 1932 to 1976 were computed based on age and number of spawning zones in otoliths of cod caught on the spawning grounds at Lofoten. A reduction in the ... -
Magnetic Compass Orientation in the European Eel
(Journal article; Peer reviewed, 2013-03-15)European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (~ 6000 km) and orientation mechanisms are unknown. Several attempts have been ... -
Major histocompatibility complex (MHC) variation and susceptibility to the sea louse Lepeophtheirus salmonis in Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2007-06-07)The relationship between genetic variation in major histocompatibility complex (MHC) Class I and II genes and susceptibility to sea lice Lepeophtheirus salmonis (Krøyer) in Atlantic salmon Salmo salar (L.) was studied ... -
Makrellen ”kokes” til døde på åpent hav
(Havforskningsnytt, Working paper, 2007)Stor makrell betales langt bedre enn mindre makrell. Når båtene i notflåten skal avgjøre kvantum og størrelsen på fisken i et kast, vil mange tørke nota så mye opp at fisken blir trengt og begynner å ”koke” før det tas ... -

Mass occurrence of (Gyrodinium aureolum) Hulburt and fish mortality along the southern coast of Norway in September-October 1981

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 ... -
Maternal 3’UTRs: from egg to onset of zygotic transcription in Atlantic cod
(Journal article; Peer reviewed, 2012-09-01)Background Zygotic transcription in fish embryos initiates around the time of gastrulation, and all prior development is initiated and controlled by maternally derived messenger RNAs. Atlantic cod egg and embryo viability ... -
Maturity changes in Norwegian spring-spawning herring Clupea harengus: compensatory or evolutionary responses?
(Journal article; Peer reviewed, 2004-05-19)The stock of Norwegian spring-spawning herring Clupea harengus collapsed to a state of commercial extinction in the 1960s, probably due to both overexploitation and unfavourable climatic conditions. Since the 1980s, the ... -
Measurements of condition and growth of cod larvae reared in mesocosms: individual variability as a function of environmental condition or genetic inheritance
(ICES CM Documents;2001/V:8, Working paper, 2001)Size, dry weight and RNA/DNA measurements of 3876 cod larvae from 26 different families of recruit and repeat spawners reared in two mesocosms ( 2500m³ and 4400m³) under natural conditions were analysed. To be able to ... -
Mechanisms regulating oocyte recruitment and skippedspawning in Northeast Arctic cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2009-09)To examine mechanisms that affect fecundity, atresia and skipped spawning in Northeast Arctic cod (Gadus morhua L.), we conducted an experiment where wild-caught cod (>60 cm) kept under restricted food regimes were subjected ... -

Microsatellite DNA used for parentage identification of partly digested Atlantic salmon (Salmo salar) juveniles through non-destructive diet sampling in salmonids
(Journal article; Peer reviewed, 2013-10-15)Predation during early life history is an important component of fitness in salmonids. Farmed Atlantic salmon display lower survival in the wild in comparison to wild salmon; however, the underlying mechanisms remain ... -
