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 ... -
Reaction norm analysis reveals rapid shifts toward delayed maturation in harvested Lake Erie yellow perch (Perca flavescens)
Gíslason, Davíð; Heino, Mikko Petteri; Robinson, Beren W.; McLaughlin, Robert B.; Dunlop, Erin S. (Peer reviewed; Journal article, 2019-01-06)Harvested marine fish stocks often show a rapid and substantial decline in the age and size at maturation. Such changes can arise from multiple processes including fisheries‐induced evolution, phenotypic plasticity, and ...
