Effect of substrate type and pellet age on the resuspension of Atlantic salmon faecal material
(Peer reviewed; Journal article, 2020) -
Effects of light source and intensity on sexual maturation, growth and swimming behaviour of Atlantic salmon in sea cages
(Peer reviewed; Journal article, 2017) -
Effects of step salinity gradients on salmon lice larvae behaviour and dispersal
(Peer reviewed; Journal article, 2019)In trying to deal with the problematic salmon louse Lepeophtheirus salmonis in salmon aquaculture, strategies to better prevent infestations are gaining traction. Successful prevention requires an accurate understanding ... -
Efficacy of salmon lice prevention via snorkel technology depends upon salinity at the farm site, with minimal effects on salmon production and welfare
(Journal article; Peer reviewed, 2019)Sea lice are a critical health issue in most salmonid farming regions. New cage-based technologies can prevent infestations from occurring, such as the ‘snorkel’, which introduces an impermeable barrier that separates ... -
Enhancing opportunistic polychaete communities under fish farms: an alternative concept for integrated aquaculture
(Journal article; Peer reviewed, 2019)This note presents the development of benthic integrated aquaculture, addressing a novel cultivation concept for open-water aquaculture. We introduce an approach that supports the colonization of indigenous polychaete ... -
Estimating the temporal overlap between post-smolt migration of Atlantic salmon and salmon lice infestation pressure from fish farms
(Journal article; Peer reviewed, 2016-09-01) -
Farmed cod escapees and net-pen spawning left no clear genetic footprint in the local wild cod population.
(Journal article; Peer reviewed, 2015-11-18)This study investigated a potential genetic introgression from farmed to wild cod Gadus morhua L. in the Trondheimsfjord, Norway. During the first 2 yr of operation of a cod farm in the inner part of the fjord, 2 large ... -
Farmed salmonids drive the abundance, ecology and evolution of parasitic salmon lice in Norway
(Peer reviewed; Journal article, 2021)Sea cage fish farming is typically open to the environment, with disease transmission possible between farmed and wild hosts. In salmonid aquaculture, salmon louse Lepeophtheirus salmonis infestations cause production ... -
Fish welfare based classification method of ocean current speeds at aquaculture sites
(Journal article; Peer reviewed, 2019)A major trend in marine aquaculture is to move production to more exposed sites with occasionally rough ocean current events. However, it is unclear whether fish will thrive in these extreme environments, since thorough ... -
Free-living Neoparamoeba perurans depth distribution is mostly uniform in salmon cages, but reshaped by stratification and potentially extreme fish crowding
(Peer reviewed; Journal article, 2017)Understanding the spatio-temporal positioning of hosts and their parasites in free-living states is useful in devising methods to diminish parasite encounters in animal production systems. We explored the potential for ... -
Growth and welfare of submerged Atlantic salmon under continuous lightning
(Peer reviewed; Journal article, 2018)ABSTRACT: Although surface-based cages dominate the marine finfish aquaculture industry, production issues that arise at the surface such as poor environmental conditions and the presence of parasites has spurred interest ... -
Growth of wild and domesticated Atlantic cod Gadus morhua reared under semi-commercial conditions
(Journal article; Peer reviewed, 2018)Genetic interactions between farmed escapees and wild fish represent a challenge to environmentally sustainable aquaculture. Breeding programs for Atlantic cod Gadus morhua have been initiated; however, the genetic response ... -
High host densities dilute sea lice Lepeophtheirus salmonis loads on individual Atlantic salmon, but do not reduce lice infection success
(Peer reviewed; Journal article, 2014) -
Impact of thermoclines on the vertical distribution of salmon lice larvae
(Peer reviewed; Journal article, 2020)Salmon louse Lepeophtheirus salmonis, a key parasite of salmonids, is managed by multiple methods at both salmon farm- and ecosystem-scale that are informed by an understanding of the abundance and distribution of the ... -
Impact of variable physical conditions and future increased aquaculture production on lice infestation pressure and its sustainability in Norway
(Peer reviewed; Journal article, 2020)Salmon lice infestation is a challenge for wild post-smolt salmon during migration from their natal river to the sea in several regions of Norway. The traffic-light management system regulates growth in the aquaculture ... -

(Peer reviewed; Journal article, 2020)Salmon lice infestation is a challenge for wild post-smolt salmon during migration from their natal river to the sea in several regions of Norway. The traffic-light management system regulates growth in the aquaculture ... -
Large-scale salmon farming in Norway impacts the epiphytic community of Laminaria hyperborea
(Peer reviewed; Journal article, 2021)Large-scale finfish farms are increasingly located in dispersive hard-bottom environments where Laminaria hyperborea forests dominate; however, the interactions between farm effluents and kelp forests are poorly understood. ... -
Limited evidence for differential reproductive fitness of wild Atlantic cod in two areas of high and low salmon farming density
(Journal article; Peer reviewed, 2018)Sea cage fish aquaculture attracts large aggregations of wild fish that feed on farm waste. Fish that associate closely with farms undergo physiological changes, and captive feeding trials indicate possible negative effects ... -
Making the best of lousy circumstances: The impact of salmon louse Lepeophtheirus salmonis on depth preference of sea trout Salmo trutta
(Peer reviewed; Journal article, 2020)Sea trout are known for seeking out sources of freshwater to rid themselves of salmon lice. However, the effect of natural haloclines in fjords on parasite dynamics is not well understood. We tagged 48 naturally infested ... -
Morphological consequences of hybridization between farm and wild Atlantic salmon Salmo salar under both wild and experimental conditions
(Peer reviewed; Journal article, 2022)The escape of Atlantic salmon Salmo salar from aquaculture has been identified as a significant threat to the persistence and stability of wild salmon populations. Yet the magnitude of phenotypic impacts due to hybridization ...
