Age-dependent patterns of spatial autocorrelation in fish populations
Marquez, Jonatan; Sæther, Bernt-Erik; Aanes, Sondre; Engen, Steinar; Salthaug, Are; Lee, Aline Magdalena (Peer reviewed; Journal article, 2021)The degree of spatial autocorrelation in population fluctuations increases with dispersal and geographical covariation in the environment, and decreases with strength of density dependence. Because the effects of these ... -
Analysis of CPUE from the Norwegian bottom trawl fleet
Salthaug, Are; Godø, Olav Rune (ICES CM Documents;2000/W:14, Working paper, 2000)Commercial logbooks with catch and effort data have been collected and recorded by the Norwegian Direcorate of Fisheries since 1971. Annual age segregated CPUE indices are calculated with different methods for North-east ... -
Can trawling effort be identified from satellite-based VMS data?
Salthaug, Are (ICES CM documents, Working paper, 2006)Data from satellite-based vessel monitoring systems (VMS) can, in principle, be used to measure fishing effort with a high spatiotemporal resolution. However, it can be difficult to separate between fishing activity and ... -
Catchability and the spatial distribution of fishing vessels
Salthaug, Are; Aanes, Sondre (Journal article; Peer reviewed, 2003)A central problem when using commercial catch per unit effort (CPUE) as an index of fish stock abundance is that fishing vessels search for concentrations of fish. For a given stock abundance, CPUE may become high if ... -

Effects of local density dependence and temperature on the spatial synchrony of marine fish populations
Marquez, Jonatan; Herfindal, Ivar; Sæther, Bernt-Erik; Aanes, Sondre; Salthaug, Are; Lee, Aline Magdalena (Peer reviewed; Journal article, 2023)Disentangling empirically the many processes affecting spatial population synchrony is a challenge in population ecology. Two processes that could have major effects on the spatial synchrony of wild population dynamics are ... -
Effekter av seismiske undersøkelser på fiskefordeling og fangstrater for garn og line i Vesterålen sommeren 2009 : Effects of seismic surveys on fish distribution and catch rates of gillnets and longlines in Vesterålen in summer 2009
