Sammenligning av fangsteffektiviteten til fiskeredskaper
Salthaug, Are (Fisken og havet, Research report, 2002)A method to determine the catching efficiency of one fishing gear relative to another is presented in this manual. The principle is to perform a number of paired comparisons between two gears by conducting catching ... -
Spatial Distribution of Different Age Groups of Herring in Norwegian Sea, May 1996–2020
Eliasen, Sólvá Káradóttir; Homrum, Eydna í; Jacobsen, Jan Arge; Kristiansen, Inga; Óskarsson, Guðmundur J.; Salthaug, Are; Stenevik, Erling Kåre (Peer reviewed; Journal article, 2021)The commercially important Norwegian spring spawning herring is characterized by its extensive annual migrations and, on a decadal timescale, large shifts in migration patterns. These changes are not well understood, but ... -
Spatial scaling of population synchrony in marine fish depends on their life history
Fredricson Marquez, Jonatan; Lee, Aline Magdalena; Aanes, Sondre; Engen, Steinar; Herfindal, Ivar; Salthaug, Are; Sæther, Bernt-Erik (Peer reviewed; Journal article, 2019)The synchrony of population dynamics in space has important implications for ecological processes, for example affecting the spread of diseases, spatial distributions and risk of extinction. Here, we studied the relationship ... -
Spatiotemporal variation in climatic conditions across ecosystems
Herfindal, Ivar; Aanes, Sondre; Benestad, Rasmus; Finstad, Anders Gravbrøt; Salthaug, Are; Stenseth, Nils Christian; Sæther, Bernt-Erik (Peer reviewed; Journal article, 2021)Environmental variation in time and space affects biological processes such as extinction risk and speed of adaptation to environmental change. The spatial structure of environmental variation may vary among ecosystems, ... -

Toktrapport [11/7 - 31/7, 2005]
Bjelland, Otte; Salthaug, Are; Smedstad, Odd M. ([Toktrapport/Havforskningsinstituttet];Nr. 22 - 2005, Working paper, 2005) -
Toktrapport [16/3 - 2/4, 2002]
Salthaug, Are ([Toktrapport/Havforskningsinstituttet];Nr. 7, Working paper, 2002)Hovedmålet for undersøkelsen er å oppnå et akustisk estimat av skreimengden i området rundt Lofoten. I tillegg blir populasjonsparametere for hyse og sei i dekningsområdet estimert. Observert skreimengde er på samme nivå ... -

Types and frequency of malformations and mortality in eggs of Arcto-Norwegian cod: A field study
Makhotin, Valeri; Solemdal, Per; Korsbrekke, Knut; Salthaug, Are (ICES CM Documents;2001/N:12, Working paper, 2001)Embryological studies on living cod eggs in NUNC-trays showed that spontaneous malformations during embryo development are lethal. They are called natural egg mortality in contrast to external lethal factors, as ...
