Prediction of goldsinny wrasse (Ctenolabrus rupestris) minimum size required to avoid escape through salmon (Salmo salar) farm nets
(Peer reviewed; Journal article, 2021)The salmon (Salmo salar) aquaculture industry has used various practices to treat salmon louse (Lepeophtheirus salmonis) infections, including mechanical, thermal, and chemical treatments. However, due to the environmental ... -
Revisiting ecological carrying capacity indices for bivalve culture
(Peer reviewed; Journal article, 2023)Ecological carrying capacity (ECC) indices for bivalve culture rely on key ecosystem turnover rates: 1. clearance time (CT), the time needed for the cultured bivalves to filter the entire bay volume; 2. renewal time (RT), ... -
Rib abnormalities and their association with focal dark spots in Atlantic salmon fillets
(Peer reviewed; Journal article, 2022)Focal dark spots (DS) represent the most common quality problem in farmed Atlantic salmon (Salmo salar L.). DS are predominantly located in the cranio-ventral region of the fillet, that is characterized by the presence of ... -
Safe limits of selenomethionine and selenite supplementation to plant-based Atlantic salmon feeds
(Journal article; Peer reviewed, 2018)The use of plant-based feeds warrants the supplementation with selenium (Se) to cover the requirement for Atlantic salmon. Depending on its chemical form, Se is a trace element with a narrow range between requirement and ... -
Salinity and temperature alter the efficacy of salmon louse prevention
(Peer reviewed; Journal article, 2023)Several promising preventive tools and strategies have been developed to combat infestation of salmon in marine cages by parasitic salmon lice. While most of the prevention strategies tested have significantly reduced louse ... -
Salmon lice dispersal and population model for management strategy evaluation
(Peer reviewed; Journal article, 2023)Modern marine salmon aquaculture includes management of salmon lice (Lepeophtheirus salmonis) infestations. Moving from a reactive delousing treatment effort to a proactive preventive strategy requires a simulation tool ... -
'Snorkel' sea lice barrier technology reduces sea lice loads on harvest-sized Atlantic salmon with minimal welfare impacts
(Journal article; Peer reviewed, 2016-02-13)The infestation of farmed Atlantic salmon (Salmo salar) by ectoparasitic sea lice (Lepeophtheirus salmonis) presents a need for new approaches to parasite control. One option is the use of ‘snorkel’ sea lice barrier ... -
Spawning manipulation, broodfish diet feeding and egg production in farmed Atlantic salmon
(Peer reviewed; Journal article, 2024)Atlantic salmon aquaculture relies on continuous supply of high quality eggs. Broodfish nutrition and manipulation of ovulation time (photoperiod and temperature) are key factors. The optimum feeding period with broodfish ... -
Tapeworm (Eubothrium sp.) infestation in sea caged Atlantic salmon decreased by lice barrier snorkels during a commercial-scale study
(Peer reviewed; Journal article, 2021)Reports of infestation by marine parasitic tapeworms (Eubothrium sp.) and an associated growth reduction in Norwegian farmed salmon are on the rise. With few acceptable treatment options available, due to drug resistance ... -
Temporal and spatial variation in food availability and meat ratio in a longline mussel farm (Mytilus edulis)
(Journal article; Peer reviewed, 2008-02-11)The influence of temporal and spatial variation in food availability on mussel meat ratio and biomass was studied in a longline mussel farm (100 m wide and 250 m long, Mytilus edulis) during an eight-month period. Current ... -
The effect of continuous light at low temperatures on growth in Atlantic salmon reared in commercial size sea pens
(Peer reviewed; Journal article, 2017) -
The importance of calibrating climate change projections to local conditions at aquaculture sites
(Peer reviewed; Journal article, 2020)Future climate projections are usually only available at global or coarse scale and the focus is often on long-term global or regional averages. Though useful to analyse general trends and identify potential risks and ... -
Triploid Atlantic salmon and triploid Atlantic salmon × brown trout hybrids have better freshwater and early seawater growth than diploid counterparts
(Peer reviewed; Journal article, 2021)The use of reproductively sterile triploid salmonids would enhance the environmental sustainability of the aquaculture industry by preventing genetic exchange between escapees and wild conspecifics. To this end, we assessed ... -
Triploid Atlantic salmon × brown trout hybrids have similar seawater growth and welfare issues as triploid Atlantic salmon, but both were heavier at harvest than their diploid counterparts
(Peer reviewed; Journal article, 2022)Interspecific hybridisation may improve the farm performance of sterile triploid salmonids via heterosis (i.e. hybrid vigour). We assessed growth over the final 293 days in seawater, and harvest quality, in diploid and ... -
Triploidy effects growth, life history strategies, and bone health in Arctic char (Salvelinus alpinus), but does not impact cataract incidence
(Peer reviewed; Journal article, 2021)Skeletal deformities and ocular cataracts have limited the farm performance of sterile triploid salmonids, but have not been assessed in Arctic char (Salvelinus alpinus). We repeatedly radiographed mixed-sex diploid and ... -
Triploidy leads to a mismatch of smoltification biomarkers in the gill and differences in the optimal salinity for post-smolt growth in Atlantic salmon
(Peer reviewed; Journal article, 2021)Sterile triploid Atlantic salmon (Salmo salar) show inconsistent seawater grow-out, but the reason why remains unclear. The purpose of this study was to determine the salinity optima of triploid post-smolts. Diploids and ... -
Vertebral column adaptations in juvenile Atlantic salmon Salmo salar, L. as a response to dietary phosphorus
(Peer reviewed; Journal article, 2021)Deficiency in dietary phosphorus (P) is considered as a nutritional risk factor for the development of vertebral column deformities in farmed Atlantic salmon Salmo salar, L. This mono-factorial study examines how 11-week ... -
Veterinary drug use in United States net pen Salmon aquaculture: Implications for drug use policy
(Peer reviewed; Journal article, 2020)Aquaculture now produces nearly half of the seafood consumed globally. Atlantic salmon (Salmo salar) is one of the top aquaculture products and the most valuable farmed marine finfish species in the United States (U.S.). ... -
Water quality and microbial community structure in juvenile Atlantic cod (Gadus morhua L.) cultures
(Journal article; Peer reviewed, 2011-06)The effect of water treatment and flow rate on young Atlantic cod juveniles was investigated in a 36-days experiment. Four different flow rates (10, 20, 40, and 70 times the effective tank volume per day) were set up in ... -
Welfare effects of environmental hypercapnia quantified by indicators based on morphology and allostatic load in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2023)Water supply is a limited resource in most salmon hatcheries, which is compensated by reduced water flow and oxygenation. However, reduced water exchange can lead to accumulation of CO2, resulting in environmental hypercapnia, ...
