Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery by increasing codend mesh openness
(Peer reviewed; Journal article, 2021)In most trawl fisheries, drag forces tend to close the meshes in large areas of diamond mesh codends, negatively affecting their selective potential. In the Barents Sea deep-water shrimp (Pandalus borealis) trawl fishery, ... -
Density independent use of shallow riverine areas in juvenile Atlantic salmon
(Journal article; Peer reviewed, 2018)Habitat use of aquatic organisms is essential to evaluate effects of many environmental challenges like effects of hydro-power regulation, where stranding may occur under hydropeaking (rapid dewatering of shallow river ... -
Drivers of diet patterns in a globally distributed freshwater fish species
(Journal article; Peer reviewed, 2018)We analysed data of a globally distributed model organism (brown trout) in an attempt to understand relationships among biogeography, prey communities and climate on diet composition at regional spatial scales (Scandinavia), ... -
Historical abundance and spatial distributions of spawners determine juvenile habitat accessibility in salmon: implications for population dynamics and management targets
(Journal article; Peer reviewed, 2013)Spatial distribution of spawning may have important ramifications for population dynamics in species where early life stages suffer from low mobility and high density-dependent mortality. Here, we use time series of spatial ... -
Homing behaviour of Atlantic salmon (Salmo salar) during final phase of marine migration and river entry
(Journal article; Peer reviewed, 2013-03-11)Little is known about Atlantic salmon behaviour during the last phase of the marine homing migration and subsequent river entry. In this study, 56 adult Atlantic salmon in the Alta Fjord in northern Norway were equipped ... -
Interactions between local population density and limited habitat resources determine movements of juvenile Atlantic salmon
(Journal article; Peer reviewed, 2017)Competition for limited resources and the resulting density-dependent processes are key factors in driving stream salmonid population dynamics. Here we test for the combined effects of density and shelter availability on ... -
Marine migration and habitat use of anadromous brown trout Salmo trutta
(Journal article, 2015)The biology and ecology of anadromous brown trout (Salmo trutta) at sea is poorly understood. This study provided information on spatial and temporal distribution of sea trout in the ocean. The behaviour of 115 individuals ... -
Nutritional correlates of spatiotemporal variations in the marine habitat use of brown trout (Salmo trutta) veteran migrants
(Journal article; Peer reviewed, 2018)The brown trout (Salmo trutta) is an iteroparous, anadromous salmonid that exhibits a complex continuum of feeding migration tactics, ranging from freshwater residency, to potamodromy, to estuarine migration, as well as ... -
Offspring size effects vary over fine spatio-temporal scales in Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2013)Classic offspring-size theory predicts that a single level of investment per offspring maximizes parental reproductive success in a given environment. Yet, substantial variation in offspring size is often observed among ... -
Potential for codends with shortened lastridge ropes to replace mandated selection devices in demersal trawl fisheries
(Peer reviewed; Journal article, 2021)In many trawl fisheries, codend size selectivity is supplemented by adding selection devices to the gear. In the Barents Sea gadoid fishery, combining diamond mesh codends with sorting grids is compulsory. However, the use ... -
Predation of Atlantic salmon across ontogenetic stages and impacts on populations
(Peer reviewed; Journal article, 2023)Managers and stakeholders increasingly ask whether predation is a driving force behind the poor status of many species, and whether predator control is likely to be a successful management action to intervene. We review ...
