Atlantic salmon Salmo salar instantaneously follow vertical light movements in sea cages
(Journal article; Peer reviewed, 2015)Atlantic salmon in marine farming environments are exposed to potentially detrimental conditions through space and time. For instance, the vertical distribution of parasitic salmon lice larvae shifts in response to changing ... -
Changes in benthic sediment conditions under an atlantic salmon farm at a deep, well-flushed coastal site
(Journal article; Peer reviewed, 2014-02-27)Along the Norwegian coastline, it is predicted that salmonid aquaculture will rapidly expand in the coming years, exceeding current production levels of 1.3 million t in 2012. This will result in increased interactions ... -
Depth distribution of the amoebic gill disease agent, Neoparamoeba perurans, in salmon sea-cages
(Journal article; Peer reviewed, 2015-07-16)Identifying where and when parasites occur in farming environments is vital to understand transmission dynamics and develop preventative measures that reduce host-parasite encounters. A major parasite concern for Atlantic ... -
Effect of ectoparasite infestation density and life-history stages on the swimming performance of Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2016-06-14)To overcome sustainability obstacles and improve operations, the Atlantic salmon farming industry is testing novel approaches to production. Redistributing farm sites to offshore locations is one such solution; however, ... -
Effect of temperature on the metabolism, behaviourand oxygen requirements of Sparus aurata
(Journal article; Peer reviewed, 2015-09-03)We investigated the effect of temperature on the limiting oxygen saturation (LOS) of gilthead sea bream Sparus aurata. This threshold was defined as the % O2 saturation where fish no longer upheld their routine metabolic ... -
Effects of salmon lice Lepeophtheirus salmonis onwild sea trout Salmo trutta—a literature review
(Journal article; Peer reviewed, 2015-08-20)Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, ... -
Fast currents reduce production performance of post-smolt Atlantic salmon.
(Journal article; Peer reviewed, 2015-09-17)In the future, an increasing number of salmon farms may be located in areas with fast water current velocity due to limited availability of more sheltered locations. However, there is little information as to how fast ... -
Genetic introgression of farmed salmon in native populations: quantifying the relative influence of population size and frequency of escapees
(Journal article; Peer reviewed, 2015-02-11)Farmed escapees may threaten the genetic integrity of native salmon populations through interbreeding. However, introgression requires survival until maturation, successful reproduction and successful early development. ... -
High host densities dilute sea lice Lepeophtheirus salmonis loads on individual Atlantic salmon, but do not reduce lice infection success
(Journal article; Peer reviewed, 2014-12-02)Host density likely plays a key role in host−parasite interactions, but empirical evidence in marine ecosystems remains limited. Classical models predict a positive relationship between host density and parasite infection ... -
Impacts of wild fishes attracted to open-cage salmonid farms in Norway
(Journal article; Peer reviewed, 2014-12-02)Salmonid farming affects both the environment and other industries, with impacts of wild fish attracted to fish farms being a major concern. Here, we summarized existing knowledge on the impacts of such aggregations around ... -
Nearby farms are a source of lice for wild salmonids: a reply to Jansen et al. (2016)
(Journal article; Peer reviewed, 2016-05-17)Jansen et al. (2016; Aquacult Environ Interact 8:349-350) question the regression analysis presented in Serra-Llinares et al. (2014; Aquacult Environ Interact 5:1-16), which correlates lice abundances on farmed and wild ... -
Statistical and ecological challengesof monitoring parasitic salmon lice infestationsin wild salmonid fish stocks
(Journal article; Peer reviewed, 2015-12-03)Ecological monitoring programmes should provide precise data to inform management, but the data quality is often limited by methodological challenges and the need for cost-effective sampling. Parasite infestations are ... -
Toward a model-based prediction system for salmon lice infestation pressure
(Journal article; Peer reviewed, 2016-09-08)High salmon lice density is a threat to wild and farmed salmonid fish in Norway. To assess and identify areas for high salmon lice infestation pressure, continuous monitoring is necessary. The national Norwegian salmon ... -
Use of fatty acid profiles to monitor the escapehistory of farmed Atlantic salmon
(Journal article; Peer reviewed, 2015-05-18)Farmed Atlantic salmon can escape from fish farms at various stages of their life, from juveniles to large mature fish. Escapees that enter rivers to spawn pose a threat to the genetic integrity of wild populations. Knowledge ...
