Genome- and transcriptomederived microsatellite loci in lumpfsh Cyclopterus lumpus: molecular tools for aquaculture, conservation and fsheries management
Maduna, Simo; Vivian-Smith, Adam; Jónsdóttir, Ólöf Dóra Bartels; Imsland, Albert; Klutsch, Cornelya; Nyman, Tommi; Eiken, Hans Geir; Hagen, Snorre (Journal article; Peer reviewed, 2020)The lumpfish Cyclopterus lumpus is commercially exploited in numerous areas of its range in the North Atlantic Ocean, and is important in salmonid aquaculture as a biological agent for controlling sea lice. Despite the ... -
Genomic Signatures of Local Adaptation under High Gene Flow in Lumpfish—Implications for Broodstock Provenance Sourcing and Larval Production
Maduna, Simo; Jónsdóttir, Ólöf Dóra Bartels; Imsland, Albert; Gíslason, Davíð; Reynolds, Patrick; Kapari, Lauri Teemu; Hangstad, Thor Arne; Meier, Kristian; Hagen, Snorre (Journal article; Peer reviewed, 2023-09-26)Aquaculture of the lumpfish (Cyclopterus lumpus L.) has become a large, lucrative industry owing to the escalating demand for “cleaner fish” to minimise sea lice infestations in Atlantic salmon mariculture farms. We used ... -
Lack of population genetic structure of lumpfish along the Norwegian coast: A reappraisal based on EST-STRs analyses
Jónsdóttir, Ólöf Dóra Bartels; Gíslason, Davíð; Ólafsdóttir, Guðbjörg; Maduna, Simo; Hagen, Snorre; Reynolds, Patrick; Sveinsson, Sæmundur; Imsland, Albert (Journal article; Peer reviewed, 2022)Lumpfish is now the single most important cleaner fish species to date and there is an extensive lumpfish translocation along the Norwegian coast. A reliable baseline information about the population genetic structure of ... -
Mitogenomics of the suborder Cottoidei (Teleostei: Perciformes): Improved assemblies, mitogenome features, phylogeny, and ecological implications
Maduna, Simo; Vivian-Smith, Adam; Jónsdóttir, Ólöf Dóra Bartels; Imsland, Albert; Klutsch, Cornelya; Nyman, Tommi; Eiken, Hans Geir; Hagen, Snorre (Journal article; Peer reviewed, 2022)We determined the mitogenome of Cyclopterus lumpus using a hybrid sequencing approach, and another four closely related species in the Liparidae based on available next-generation sequence data. We found that the mitogenome ... -
Quantification of grazing efficacy, growth and health score of different lumpfish (Cyclopterus lumpus L.) families: possible size and gender effects
Imsland, Albert; Reynolds, Patrick; Hangstad, Thor Arne; Kapari, Lauri Teemu; Maduna, Simo; Hagen, Snorre B.; Jónsdóttir, Ólöf Dóra Bartels; Spetland, Frank; Lindberg, Ken Ståle (Journal article; Peer reviewed, 2021)To investigate the possible family influence on sea lice grazing of lumpfish on Atlantic salmon, ten families of lumpfish (N = 480) with a mean (± SD) weight of 54.8 ± 9.2 g were distributed among ten sea cages (5 × 5 × 5 ... -
Towards better lumpfish: Changes in size variation, cataract development, behaviour and sea lice grazing through selective breeding
Imsland, Albert; Reynolds, Patrick; Kapari, Lauri Teemu; Maduna, Simo; Hagen, Snorre; Hanssen, Anne; Jónsdóttir, Ólöf Dóra Bartels (Journal article; Peer reviewed, 2024)The aim of this study was to evaluate whether sea lice grazing efficiency, behaviour, size variation and cataract development can be improved through selective breeding of lumpfish. A series of studies was conducted over ...
