Delousing Efficacy and Physiological Impacts on Atlantic Salmon of Freshwater and Hyposaline Bath Treatments
Thompson, Cameron; Madaro, Angelico; Oppedal, Frode; Stien, Lars Helge; Bui, Samantha (Rapport fra havforskningen;2023 - 11, Research report, 2023)A pilot study was conducted to investigate the delousing efficacy and physiological effects of freshwater and hyposaline water in Atlantic salmon ( Salmo salar ) for various treatment durations. There were four primary ... -
Disentangling the key drivers of salmon louse Lepeophtheirus salmonis fecundity using multiyear field samples
Thompson, Cameron; Bui, Samantha; Dalvin, Sussie Trine; Skern-Mauritzen, Rasmus (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 ... -
Fluorolice - Final report for FHF project 901508
Skern-Mauritzen, Rasmus; Thompson, Cameron; Dalvin, Sussie; Thorsen, Anders; Bui, Samantha; Nordi, Gunnvør á; Bron, James E.; Fordyce, Mark (Rapport fra havforskningen;2021 - 30, Research report, 2021)Salmon lice ( Lepeophtheirus salmonis ) represent a substantial obstacle for the sustainability of salmon farming (Torrissen, et al. 2013; Vollset, et al. 2018). As such, there are many avenues of research that aim to ... -
Illuminating the planktonic stages of salmon lice: A unique fluorescence signal for rapid identification of a rare copepod in zooplankton assemblages
Thompson, Cameron; Bron, James E.; Bui, Samantha; Dalvin, Sussie; Fordyce, Mark; Furmanek, Tomasz; Nordi, Gunnvør á; Skern-Mauritzen, Rasmus (Peer reviewed; Journal article, 2021)Monitoring of planktonic salmon louse (Lepeophtheirus salmonis salmonis) abundance and parameterization of key life-history traits has been hindered by labour-intensive and error-prone quantification using traditional light ... -
A novel method for the rapid enumeration of planktonic salmon lice in a mixed zooplankton assemblage using fluorescence
Thompson, Cameron; Bron, James Emmanuel; Bui, Samantha; Dalvin, Sussie; Fordyce, Mark; Nordi, Gunnvør á; Skern-Mauritzen, Rasmus (Peer reviewed; Journal article, 2022)The relative rarity of the planktonic larval stages of salmon lice in comparison to other animals captured in a zooplankton assemblage is an obstacle to estimating their abundance and distribution. Due to the labour ... -
Optimising delousing strategies: developing best practice recommendations for maximal efficacy and positive welfare - Final Report
Bui, Samantha; Skern-Mauritzen, Rasmus; Saito, Takaya; Thompson, Cameron (Rapport fra havforskningen;, Research report, 2023)The salmon aquaculture industry currently uses a range of strategies to combat salmon louse epidemics, however acute delousing methods are limited due to poor efficacy, poor welfare and environmental impacts, or potential ... -
A positive temperature-dependent effect of elevated CO<inf>2</inf> on growth and lipid accumulation in the planktonic copepod, Calanus finmarchicus
Fields, David M.; Runge, Jeffrey A.; Thompson, Cameron; Durif, Caroline; Shema, Steven D.; Bjelland, Reidun Marie; Niemisto, Maura; Arts, Michael T.; Skiftesvik, Anne Berit; Browman, Howard (Peer reviewed; Journal article, 2022)Calanus finmarchicus were reared from eggs to adults at 12°C and 16°C with non-limiting food in combination with ambient (600 μatm) and high (1100 μatm) pCO2. These conditions are likely to be encountered by the species ... -
Production, fasting and delousing of triploid and diploid salmon in Northern Norway - Report for the 2020-generation
Stien, Lars Helge; Thompson, Cameron; Fjelldal, Per Gunnar; Oppedal, Frode; Kristiansen, Tore S; Sæther, Per Anton; Bølgen, Per Magne; Martinsen, Lisbeth (Rapport fra havforskningen;2023 - 20, Research report, 2023)This report is an investigation into the 2020 generation of triploid salmon in Northern Norway and their diploid comparators. The trajectory of 16 fish groups comprising more than 10 million fish is described throughout ... -
Rapid climate-driven circulation changes threaten conservation of endangered north atlantic right whales
Record, Nicholas R; Runge, Jeffrey A.; Pendleton, Daniel; Balch, William M; Davies, Kimberley T A; Pershing, Andrew; Johnson, Catherine Lynn; Stamieszkin, Karen; Ji, Rubao; Feng, Zhixuan; Kraus, Scott D; Kenney, Robert D; Hudak, Christy A; Mayo, Charles A; Chen, Changsheng; Salisbury, Joseph E.; Thompson, Cameron (Journal article; Peer reviewed, 2019)As climate trends accelerate, ecosystems will be pushed rapidly into new states, reducing the potential efficacy of conservation strategies based on historical patterns. In the Gulf of Maine, climate-driven changes have ... -
