Discrete water quality sampling at open-water aquaculture sites: limitations and strategies
(Peer reviewed; Journal article, 2016) -
Disentangling the key drivers of salmon louse Lepeophtheirus salmonis fecundity using multiyear field samples
(Peer reviewed; Journal article, 2023)Planktonic salmon louse Lepeophtheirus salmonis salmonis larvae produced at sal - mon farms spread to and infect both wild and farmed salmonids. Understanding and forecasting the production and distribution of these larval ... -
Effect of substrate type and pellet age on the resuspension of Atlantic salmon faecal material
(Peer reviewed; Journal article, 2020) -
An effective method for the recapture of escaped farmed salmon
(Journal article; Peer reviewed, 2011-04-04)The search for effective strategies to prevent and mitigate accidental releases of aquaculture fishes is on-going. To test a new recapture strategy and evaluate the individual dispersal behaviour of escaped farmed Atlantic ... -
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 salmon lice infection on the behaviour of sea trout in the marine phase
(Journal article; Peer reviewed, 2014-07-09)Salmon lice Lepeophtheirus salmonis Krøyer may affect survival and growth of anadromous salmonids through physiological stress and/or behavioural changes. Using acoustic telemetry tracking, we investigated the behaviour ... -
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) -
Extent and ecological importance of escape through spawning in sea-cages for Atlantic cod
(Journal article; Peer reviewed, 2012-11-14)The culture of certain fish species to sizes at which they can reproduce has led to the escape of fertilised eggs or ‘escape through spawning’. To investigate the extent and ecological importance of spawning in sea-cages ... -
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 ... -
Feeding preference of recaptured Atlantic salmon Salmo salar following simulated escape from fish pens during autumn
(Journal article; Peer reviewed, 2010-12-21)Escapes of farmed fish from coastal farms around the world are believed to have genetic and ecological consequences for wild fish populations. Each year there are numerous escapes of adult farmed Atlantic salmon Salmo ... -

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 ... -
Forensic identification of fish farm escapees: the Norwegian experience
(Journal article; Peer reviewed, 2010-03-31)Aquaculture management authorities require the ability to identify the farm of origin for escaped fish. Physical tagging is routinely conducted for domesticated animals (e.g. sheep and cattle); however, there are considerable ... -
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 ...
