Rapid water temperature variations at the northern shelf of the Yellow Sea
(Peer reviewed; Journal article, 2021)During summer, there is great spatial variability in bottom water temperature on the northern shelf of the Yellow Sea. This variability is associated with a thermal front along the shelf. Oscillatory currents from semidiurnal ... -
Recapture of cultured salmon following a large-scale escape experiment
(Journal article; Peer reviewed, 2010-10-19)A large-scale escape experiment using 1031 adult Atlantic salmon Salmo salar L. was performed in the Hardangerfjord in western Norway to study the dispersal of escaped salmon, evaluate the effect of a gill-net fishery ... -

Reduced migratory performance of farmed Atlantic salmon post-smolts from a simulated escape during autumn
(Journal article; Peer reviewed, 2010-11-10)Escape of migratory finfish species from fish farms, such as Atlantic salmon Salmo salar L., offer a challenge when considering the environmental risks of cage culture. The migratory behaviour of groups of cultured salmon ... -

Reduced physiological performance in a free-living coralline alga induced by salmon faeces deposition
(Peer reviewed; Journal article, 2021)Maerl beds are formed by the accumulation of free-living coralline algae and have considerable ecological significance due to the high diversity of associated fauna and flora. The rapid expansion of the Atlantic salmon Salmo ... -
Resilience of dynamic coastal benthic ecosystems in response to large-scale finfish farming
(Journal article; Peer reviewed, 2019)Global expansion of salmon aquaculture is contingent upon finding new, large-capacity farming locations that are, increasingly, situated in dispersive environments with atypical ecological characteristics. The capacity of ... -
Salmon lice dispersion in a northern Norwegian fjord system and the impact of vertical movements
(Journal article; Peer reviewed, 2016-02-02)The abundance and distribution of salmon lice Lepeophtheirus salmons originating from fish farms in a northern Norwegian fjord during the summer of 2010 was investigated by means of a numerical model, underpinned by field ... -
Salmon lice infection on wild salmonids in marine protected areas: an evaluation of the Norwegian ‘National Salmon Fjords
(Journal article; Peer reviewed, 2014-02-05)In Norway, 29 fjords and 52 rivers have been designated for protection in order to prevent the infection of important populations of wild salmonids with salmon lice of farm origin. We evaluated the effect of this protection ... -
Salmon lice nauplii and copepodids display different vertical migration patterns in response to light
(Peer reviewed; Journal article, 2021)Light is a fundamental environmental cue which influences the migration of many marine organisms. For the salmon louse Lepeophtheirus salmonis, light is believed to drive the diel vertical migration behaviour of their ... -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Journal article; Peer reviewed, 2019)Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ... -
Sampling planktonic salmon lice in Norwegian fjords
(Journal article; Peer reviewed, 2019)Risk of mortality of wild salmon caused by salmon lice is used as an index for managing aquaculture production in Norway and is based on monitoring of lice attached to wild salmonids and modelled concentrations of lice ... -
Sea lice prevention strategies affect cleaner fish delousing efficacy in commercial Atlantic salmon sea-cages
(Peer reviewed; Journal article, 2020)Over the last 2 decades, cleaner fishes have been employed to remove external sea lice parasites from Atlantic salmon Salmo salar in sea cages. Norway, Scotland, Ireland, and the Faroe Islands combined now use ~60 million ... -
Sea lice removal by cleaner fish in salmon aquaculture: a review of the evidence base

Spatial response of hard- and mixed-bottom benthic epifauna to organic enrichment from salmon aquaculture in northern Norway
(Peer reviewed; Journal article, 2021)Norwegian Atlantic salmon aquaculture is continuing to expand in northern regions dominated by hard- and mixed-bottom substrates. Such habitats contain rich benthic epifaunal communities, including sponges and other sessile ... -
Spatio-temporal dynamics in the dissolved nutrient waste plume from Norwegian salmon cage aquaculture
(Peer reviewed; Journal article, 2018)The aim of this study was to define the waste plume dynamics around a salmon farm in Norway. Systematic water sampling and numerical modeling were implemented to define nutrient concentrations in the upper water column at ... -

Stable isotope marking of otoliths during vaccination: a novel method for mass-marking fish
(Journal article; Peer reviewed, 2014-06-04)Tagging or marking of fishes enables the collection of population-based information for ecological research, yet few techniques enable 100% mark detection success. We tested a new mass-marking technique: otolith marking ... -
Surface environment modification in Atlantic salmon sea-cages: Effects on amoebic gill disease, salmon lice, growth and welfare
(Journal article; Peer reviewed, 2018)Surface environment modification is a potential parasite control strategy in Atlantic salmon sea-cage farming. For instance, a temporary low salinity surface layer in commercial-scale snorkel sea-cages has coincided with ... -
