Density-dependent migratory waves in the marine pelagic ecosystem
(Journal article; Peer reviewed, 2006-11)The migration of large aggregations of animals that sweep through the landscape is a phenomenon with large consequences in many ecosystems. It has been suggested that such migrations are mediated by resource depletion. ... -
Cod and climate: effect of the North Atlantic Oscillation on recruitment in the North Atlantic
(Journal article; Peer reviewed, 2006-11-07)The impact of the environment on interannual variability in fish recruitment has proven difficult to establish empirically, and environment-recruitment correlations have often been found to break down when more data become ... -

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 ... -

The effect of green water and light intensity on survival, growth and lipid composition in Atlantic cod (Gadus morhua) during intensive larval rearing [postprint]
(Journal article; Peer reviewed, 2007)The effects of green water and light intensity on establishment of exogenous feeding, survival, growth, and lipid and fatty acid composition were investigated for larvae of Atlantic cod in two replicate experiments. In ... -

Calibration sphere for low-frequency parametric sonars
(Journal article; Peer reviewed, 2007)The problem of calibrating parametric sonar systems at low difference frequencies used in backscattering applications is addressed. A particular parametric sonar is considered: the Simrad TOPAS PS18 Parametric Sub-bottom ... -

Observing individual fish behavior in fish aggregations: Tracking in dense fish aggregations using a split-beam echosounder
(Journal article; Peer reviewed, 2007)Acoustic instruments are important tools for observing the behavior of aquatic organisms. This paper presents a simple but efficient method for improving the tracking of closely spaced targets using a split-beam echosounder. ... -
Acoustic data collected during and between bottom trawl stations: consistency and common trends
(Journal article; Peer reviewed, 2007)Acoustic data are often collected during bottom trawl surveys. Their use can potentially improve the precision and accuracy of fish abundance estimates if acoustic data collected between trawl stations are consistent with ... -
Changes in baseline growth and maturation parameters of Northwest Atlantic porbeagle, Lamna nasus, following heavy exploitation
(Journal article; Peer reviewed, 2007)We tested for density-dependent changes in growth and maturation of Northwest Atlantic porbeagle (Lamna nasus) after the population declined by 75%-80% from fishing. Vertebrae and reproductive data collected from the virgin ... -
Registreringer av lakselus på laks, sjøørret og sjørøye i 2006
(NINA rapport;, Research report, 2007)Resultatene fra 2006 viste at infeksjonstrykket varierte noe mellom vassdragene i tid og rom, men at det generelt var moderat til høy infeksjon i alle undersøkelsesområdene foruten i Altafjorden. Dette til tross for at ... -
Estimation of the parameters of fish stock dynamics from catch-at-age data and indices of abundance: can natural and fishing mortality be separated?
(Journal article; Peer reviewed, 2007)Models for fluctuations in size of fish stocks must include parameters that describe expected dynamics, as well as stochastic influences. In addition, reliable population projections also require assessments about the ... -
The concept of fecundity regulation in plaice (Pleuronectes platessa) tested on three Irish Sea spawning populations
(Journal article; Peer reviewed, 2007)The fecundity of European plaice (Pleuronectes platessa) in the Irish Sea between 2000 and 2004 was estimated during the spawning season for fish in the three main spawning areas (Liverpool Bay, the Cumbrian coast, and the ... -

Silent research vessels are not quiet
(Journal article; Peer reviewed, 2007)Behavior of herring Clupea harengus stimulated by two ocean-going research vessels; respectively designed with and without regard to radiated-noise-standards. Both vessels generate a reaction pattern, but, contrary to ... -
Detection of nodavirus in seawater from rearing facilities for Atlantic halibut Hippoglossus hippoglossus larvae
(Journal article; Peer reviewed, 2007-01-18)We used (1) ultracentrifugation followed by RT-PCR and (2) real-time RT-PCR to detect and quantify nodaviruses in seawater in which Atlantic halibut Hippoglossus hippoglossus larvae/fry had been held at rearing facilities. ... -
Fate of infectious salmon anaemia virus (ISAV) in experimentally challenged blue mussels Mytilus edulis
(Journal article; Peer reviewed, 2007-02-08)In order to investigate the potential role of blue mussels Mytilus edulis as a vector of the fish pathogenic infectious salmon anaemia virus (ISAV), we developed an experimental bioaccumulation system in which mussels can ...
