Modelling age-dependent natural mortality of juvenile Norwegian spring-spawning herring (Clupea harengus L.) in the Barents Sea
(PINRO-IMR Symposium, Conference object, 1995)Understanding the patterns of mortality in the juvenile stages is essential for improving current stock assessment procedures. A crucial aspect is at which stage in the life cycle of fish is year-class strength determined. ... -
Modelling and interpreting fish bioenergetics – a role for behaviour, life-history traits, and survival trade-offs
(Journal article; Peer reviewed, 2016-01-14)Bioenergetics is used as the mechanistic foundation of many models of fishes. As the context of a model gradually extends beyond pure bioenergetics to include behaviour, life-history traits and function and performance of ... -
Modelling benthic habitats and biotopes off the coast of Norway to support spatial management.
(Journal article; Peer reviewed, 2015-06-25)Habitat conservation, and hence conservation of biodiversity hinges on knowledge of the spatial distribution of habitats, not least those that are particularly valuable or vulnerable. In offshore Norway, benthic habitats ... -
Modelling chemical releases from fish farms: impact zones, dissolution time, and exposure probability
(Peer reviewed; Journal article, 2021)Tarpaulin bath treatments are used in open net-pen finfish aquaculture to combat parasitic infections, in particular sea lice. After treatment, the toxic wastewater is released directly into the ocean, potentially harming ... -
Modelling Diurnal Variation in Bottom Trawl Catches and Potential Application in Surveys
(ICES CM documents, Working paper, 1999)Diurnal variability in bottom trawl survey catches may influence the quality of the survey results when not taken properly into account. This is especia]!.y the case if diurnal effects vary substantiaIly from year to ... -
Modelling drift of pelagic offspring: the importance of egg surveys in providing a realistic model initialization.
(Journal article; Peer reviewed, 2015-07-11)Having valid information about the location and dynamics of biological processes is important for coastal management. In this context modelling, the pelagic drift of early life stages has been shown to be an important tool ... -
Modelling herring target strength pressure dependence in the frequency domain
(ICES CM documents, Working paper, 2001)Improved understanding of the acoustic scattering properties of the fish is needed when trying to remove potential bias is acoustic abundance estimates. The paper address the problem of systematic pressure or depth dependency ... -
Modelling maturity ogive for Northeast Arctic saithe
(Working paper, 2008) -
Modelling of the Svalbard fjord Hornsund
(Peer reviewed; Journal article, 2017) -
Modelling PCB-153 in northern ecosystems across time, space, and species using the nested exposure model
(Peer reviewed; Journal article, 2023)There is concern over possible effects on ecosystems and humans from exposure to persistent organic pollutants (POPs) and chemicals with similar properties. The main objective of this study was to develop, evaluate, and ... -
Modelling rule-based behaviour: habitat selection and the growth–survival trade-off in larval cod
(ICES CM documents;2009/T:03, Working paper, 2009) -
Modelling salmon lice copepodids along the Norwegian coast – comparing old and new particle tracking models
(Rapport fra havforskningen;39-2018, Research report, 2018) -
Modelling the advection and diffusion of eggs and larvae of Northeast Arctic Greenland halibut
(ICES CM documents, Working paper, 1999)In later years there has been considerable uncertainty on the recruitment of the northeast Arctic stock of Greenland halibut (Reinhardtius hyppoglossoides). The abundance of several year classes originally considered ... -
Modelling the dispersal of Cape hake ichthyoplankton
(ICES CM documents;, Working paper, 2010) -
Modelling the dynamics of harmful blooms of Chattonella sp. in the Skagerrak and the Kattegat
(ICES CM documents;2006/E:12, Working paper, 2006)The presentation shows observations, satellite images and model results describing the growth and spreading of Chattonella sp. flagellates in the Skagerrak and the Kattegat. Chattonella sp. is a harmful alga that may cause ... -
Modelling the sources of mortality for larval haddock on Georges Bank and their effects on behavior
(ICES CM documents;2009/T:08, Working paper, 2009)Fish larvae have the ability to change their vertical position in the water column and thusly cannot be treated as passive particles in coupled biological-physical individualbased models (IBMs). The vertical variability ... -
Modelling the spatial shifts of functional groups in the Barents Sea using a climate-driven spatial food web model
(Peer reviewed; Journal article, 2023)We built a dynamic, spatial food web model for the Barents Sea, developed with Ecospace by including species’ habitat requirements and ecological interactions. The model was used to test the spatial shifts of different ... -
Modelling the variability of the drift of blue whiting larvae and its possible importance for recruitment
(ICES CM Documents;1996/S:31, Working paper, 1996)The first 8 months of the drift of blue whiting larvae has been simulated and studied for the 20 year period 1976-1994, using the 3-dimensional numerical model system NORWECOM (the NORWegian ECOlogical Model system). The ... -
