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 ... -
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 ... -
Improved method for triacylglycerol-derived fatty acid profiling by various non-lethal and lethal sampling techniques in Atlantic salmon
(Journal article; Peer reviewed, 2013-11-14)The current paper compares the use of adipose fin and muscle biopsies as non-lethal sampling procedures, and the suitability of triacylglycerol (TAG) versus total lipid (TOT) fatty acid composition (fatty acid methyl esters, ... -
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 ... -
Migratory behaviour and ocean survival of escaped out-of-season smolts of farmed Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2013-04-10)A large proportion of farmed Atlantic salmon Salmo salar L. smolts are produced under intensive rearing conditions. They reach smolt size and are transferred to net pens in seawater during their first autumn under a short ... -
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 ... -
Mortality and reduced photosynthetic performance in sugar kelp Saccharina latissima caused by the salmon-lice therapeutant hydrogen peroxide
(Journal article; Peer reviewed, 2019)Sugar kelp Saccharina latissima is one of the dominating kelp species on sheltered sublittoral sites along the Norwegian coastline, providing important habitats and ecosystem services. In finfish aquaculture in Norway, ... -
Mortality in the rockpool shrimp Palaemon elegans following long-term exposure to low doses of the anti-parasitic drug Teflubenzuron
(Peer reviewed; Journal article, 2020)Anti-parasitic drugs used to control sea lice infestations in the salmonid aquaculture industry are a growing environmental concern due to their potential impacts on non-target crustacean species. This study examined the ... -
Movements of grey mullet Liza aurata and Chelon labrosus associated with coastal fish farms in the western Mediterranean Sea
(Journal article; Peer reviewed, 2010-11-10)Grey mullet occur in abundance around sea bream and sea bass farms where they forage on waste fish feed, a behaviour that could modify their natural movement pattern and distribution. In this study, we used visual census ... -
Mussel farming production capacity and food web interactions in a mesotrophic environment
(Peer reviewed; Journal article, 2023)Low trophic aquaculture (LTA), such as bivalve farming, offers promising avenues to supply sustainable seafood and aquafeed. While bivalve farming usually occurs in highly productive coastal areas which already support ... -
Net-biting and escape behaviour in farmed Atlantic cod Gadus morhua: effects of feed stimulants and net traits
(Journal article; Peer reviewed, 2012-09-25)Preventing farmed fish from escaping sea cages is a major challenge for developing sustainable aquaculture practices. In this study, the individual behaviour of Atlantic cod Gadus morhua to inspect and bite the net was ... -
No environmental effect on vaccine-induced reduced growth in Atlantic salmon Salmo salar smolts
(Peer reviewed; Journal article, 2020)Oil-adjuvanted vaccines reduce long-term growth in farmed Atlantic salmon Salmo salar, possibly via an increase in metabolic rate due to the energetic demands of the immune system. We tested this hypothesis by comparing ... -
Not too slow, not too fast: water currents affect group structure, aggression and welfare in postsmolt Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2016) -
Optimal estimation of lice release from aquaculture based on ambient temperatures
(Peer reviewed; Journal article, 2020)Models for mapping and forecasting infective pressure from salmon louse Lepeophtheirus salmonis larvae are of major importance in the Norwegian government’s management of salmonid aquaculture. These models use site-reported ... -
Oxygen gradients affect behaviour of caged Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2017)Dissolved oxygen (DO) conditions in marine aquaculture cages are heterogeneous and fluctuate rapidly. Here, by temporarily wrapping a tarpaulin around the top 0 to 6 m of a marine cage (~2000 m3), we manipulated DO to ... -
