Temporal synchrony and variation in abundance of Atlantic salmon (Salmo salar) in two subarctic Barents Sea rivers: influence of oceanic conditions
(Journal article; Peer reviewed, 2004)Long-term variation in Atlantic salmon (Salmo salar) stocks was analyzed in two Barents Sea rivers, the Teno and Näätämöjoki, that represent the northernmost distribution area of the species. In contrast to most of the ... -
Sounds produced by Norwegian killer whales, Orcinus orca, during capture
(Journal article; Peer reviewed, 2004)To date very little is still known about the acoustic behavior of Norwegian killer whales, in particular that of individual whales. In this study a unique opportunity was presented to document the sounds produced by five ... -

Complete sequence of RNA1 and subgenomic RNA3 of Atlantic halibut nodavirus (AHNV)
(Journal article; Peer reviewed, 2004-03-10)The Nodaviridae are divided into the alphanodavirus genus, which infects insects, and the betanodavirus genus, which infects fishes. Betanodaviruses are the causative agent of viral encephalopathy and retinopathy (VER) in ... -

Overvåking av forurensningsituasjonen i indre Oslofjord 2003 [Fagrådsrapport nr. 95]
(NIVA-rapport;OR-4845, Research report, 2004-05-05)Rapporten omhandler resultatene fra undersøkelser foretatt i indre Oslofjord hovedsakelig i 2003. Dypvannsfornyelsen var god i Vestfjorden, men beskjeden i Bunnefjorden. Oksygenforholdene har blitt bedre i Vestfjorden siden ... -
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 ... -
Non-linear dynamics in marine-phytoplankton population systems
(Journal article; Peer reviewed, 2004-06-08)Although non-linear density-dependence has been widely emphasized in population dynamics studies, the existence of non-linear exogenous forces have been less explored. In articular, we propose that the formulation of ... -
Indirect climatic forcing of the Barents Sea capelin: a cohort effect
(Journal article; Peer reviewed, 2004-06-08)Planktivorous capelin is a key species in the Barents Sea, being of great importance in the exploitation of plankton production in this subarctic region. However, in years with a successful reproduction of the Norwegian ... -

Fish harvesting, marine reserves, and distribution of individuals over space
(Journal article; Peer reviewed, 2004-08-05)We analysed exploitation of populations that are partly protected in a marine harvest refuge to prevent their over-harvesting in the remaining unprotected area. We carried out our analysis by introducing the model of ideal ... -
Effect of turbulence on the energetics of foraging in Atlantic cod Gadus morhua larvae
(Journal article; Peer reviewed, 2004-11-01)A net energy gain (NEG) model was used to assess the effects of turbulence on the energy budget of Atlantic cod Gadus morhua larvae, feeding on copepod nauplii at different concentrations. The geometry of their prey search ... -
Tracking individual fish from a moving platform using a split-beam transducer
(Journal article; Peer reviewed, 2005)Tracking of individual fish targets using a split-beam echosounder is a common method for investigating fish behavior. When mounted on a floating platform like a ship or a buoy, the transducer movement often complicates ...
