Are low but statistically significant levels of genetic differentiation in marine fishes ‘biologically meaningful’? A case study of coastal Atlantic cod
(Journal article; Peer reviewed, 2010-12-29)A key question in many genetic studies on marine organisms is how to interpret a low but statistically significant level of genetic differentiation. Do such observations reflect a real phenomenon, or are they caused by ... -
Biomarkers in Natural Fish Populations Indicate Adverse Biological Effects of Offshore Oil Production
(Journal article; Peer reviewed, 2011-05-23)Background: Despite the growing awareness of the necessity of a sustainable development, the global economy continues to depend largely on the consumption of non-renewable energy resources. One such energy resource is ... -
Early ontogeny of the Atlantic halibut Hippoglossus hippoglossus head
(Journal article; Peer reviewed, 2011-04-04)An ontogenetic sequence of Atlantic halibut Hippoglossus hippoglossus larvae, reared in intensive culture conditions, was cleared and stained and histologically processed to determine normal cranial chondrification for ... -
Effects of acute oil spills on the Norwegian marine environment
(Conference object, 2011-05) -
Effects of different modified diets on growth, digestive enzyme activities and muscle compositions in juvenile Siamese fighting fish (Betta splendens Regan, 1910)
(Journal article; Peer reviewed, 2011-10-12)The effects of four modified diets (gamma-irradiated, microwave-irradiated, probiotic-supplemented and carbohydrase-supplemented diets) were studied on digestive enzyme specific activities and growth performance quality ... -
Foraging behaviour of larval cod (Gadus morhua) at low light intensities
(Journal article; Peer reviewed, 2011-02-13)The ability to forage at low light intensities can be of great importance for the survival of fish larvae in a pelagic environment. Three-dimensional silhouette imaging was used to observe larval cod foraging and swimming ... -
An Integrated Assessment of changes in the thermohaline circulation
(Journal article; Peer reviewed, 2009-03-27)This paper discusses the risks of a shutdown of the thermohaline circulation (THC) for the climate system, for ecosystems in and around the North Atlantic as well as for fisheries and agriculture by way of an Integrated ... -
Joint Norwegian-Russian environmental status 2008 : report on the Barents Sea Ecosystem, part II - complete report

Kartlegging og analyser av faunaen i Hardangerfjorden før mulig legging av elektrisk kabel i korridor
(Fisken og havet;1-2011, Research report, 2011-01-31)In relation to a possible cable pathway on the sea floor through the inner half of the Hardanger fjord, the Institute for Marine Research has carried out ROV inspections of the benthic faunal communities along 17 selected ... -
Lipid and fatty acid digestibility in Calanus copepod and krill oil by Atlantic halibut (Hippoglossus hippoglossus L.)
(Journal article; Peer reviewed, 2010-12-24)Marine zooplankton represent a significant biomass of marine lipid that could supply lipid in diets for farmed marine fish. Digestibility of lipid and fatty acids of the copepod, Calanus finmarchicus and Antarctic krill, ... -
MAREANO kartlegger havbunnen : MAREANO – mapping Norwegian seabed
(Havforskningsnytt, Working paper, 2008)Since the MAREANO programme was initiated in 2006, it has mapped 37 000 square kilometres of seabed off the Norwegian counties of Troms and Nordland. On the most recent expedition in June 2008, samples were collected and ... -
North Sea sensitivity to atmospheric forcing
(Journal article; Peer reviewed, 2011-04)The sensitivity of North Sea physics and phytoplankton production to atmospheric forcing has been studied by performing perturbations of the atmospheric forcing fields through a number of model simulations. The perturbations ... -
Stimfisk - et viktig element i det dynamiske havmiljøet

The three-dimensional prey field of the northern krill, Meganyctiphanes norvegica, and the escape responses of their copepod prey
(Journal article; Peer reviewed, 2010-02-24)In the north Atlantic, Meganyctiphanes norvegica feeds predominantly on copepods, including Calanus spp. To quantify its perceptual field for prey, and the sensory systems underlying prey detection, the responses of tethered ... -
Undersøkelser av A-felt for tarehøsting i Møre og Romsdal og Sør-Trøndelag i 2011
(Rapport fra Havforskningen;Nr. 13-2011, Working paper, 2011-10-07)Norsk: Havforskningsinstituttet gjennomførte i juni 2011 undersøkelser av A-høstefelt for tare i Møre og Romsdal og Sør-Trøndelag. Tarevegetasjonens tilstand og tetthet av kråkeboller ble undersøkt ved hjelp av ... -
