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 ... -
In situ sea lice egg sterilization with UVC light
Bui, Samantha; Oppedal, Frode; Barrett, Luke; Dempster, Tim; Pert, Cassie (Rapport fra havforskningen;2019 - 29, Research report, 2019)Sea-cage salmon farming creates ideal conditions for population growth of the salmon louse Lepeophtheirus salmonis, potentially leading to poor welfare and mortality in farmed salmon and nearby wild salmonids. Frequent ... -
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 ... -
Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids
Skern-Mauritzen, Rasmus; Sissener, Nini; Sandvik, Anne Dagrun; Meier, Sonnich; Sævik, Pål Næverlid; Skogen, Morten D.; Vågseth, Tone; Dalvin, Sussie; Skern-Mauritzen, Mette; Bui, Samantha (Peer reviewed; Journal article, 2020)The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ... -
Salmon lice evasion, susceptibility, retention, and development differ amongst host salmonid species.
Bui, Samantha; Haltuunen, Elina; Mohn, Agnes; Vågseth, Tone; Oppedal, Frode (Peer reviewed; Journal article, 2017)With different ecological characteristics amongst salmonid species, their response to parasitic infestation is likely to vary according to their spatial and temporal overlap with the parasite. This study investigated the ... -
Salmon lice survive the straight shooter: A commercial scale sea cage trial of laser delousing
Bui, Samantha; Geitung, Lena; Oppedal, Frode; Barrett, Luke T. (Peer reviewed; Journal article, 2020)Ectoparasitic salmon louse (Lepeophtheirus salmonis) infestations are costly for Atlantic salmon (Salmo salar) farmers in Norway. As a result, there is a strong desire for solutions to prevent and control infestations, and ... -
Sea lice prevention strategies affect cleaner fish delousing efficacy in commercial Atlantic salmon sea-cages
Gentry, Katherine; Bui, Samantha; Oppedal, Frode; Dempster, Timothy David (Peer reviewed; Journal article, 2020)Over the last 2 decades, cleaner fishes have been employed to remove external sea lice parasites from Atlantic salmon Salmo salar in sea cages. Norway, Scotland, Ireland, and the Faroe Islands combined now use ~60 million ... -
'Snorkel' sea lice barrier technology reduces sea lice loads on harvest-sized Atlantic salmon with minimal welfare impacts
Stien, Lars Helge; Dempster, Timothy David; Bui, Samantha; Glaropoulos, Alexis; Fosseidengen, Jan Erik; Wright, Daniel W.; Oppedal, Frode (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 ... -
Summary and status of deep lights and deep feed use in commercial settings: welfare, behaviour and infestation at three case study sites — End report from the FHF projects 901154 “Dypelysogfôring”
Bui, Samantha; Oppedal, Frode; Nilsson, Jonatan; Oldham, Tina Marie Wier; Stien, Lars Helge (Rapport fra havforskningen, Research report, 2019)Infective salmon lice are attracted to light and are therefore more abundant near the surface than deep in the cage. Manipulating salmon swimming depth by the use of deep lights and deep feeding could therefore spatially ... -
