Acute effects of gas supersaturation on Atlantic salmon smolt in two Norwegian rivers
Stenberg, Sondre Kvalsvik; Velle, Gaute; Pulg, Ulrich; Skoglund, Helge (Journal article; Peer reviewed, 2020)Total dissolved gas (TDG) supersaturation downstream of hydropower plants may cause gas bubble disease (GBD) and harmful effects in fish. Little is known about tolerance levels of TDG supersaturation on Atlantic salmon ... -
Does vaterite otolith deformation affect post-release survival and predation susceptibility of hatchery-reared juvenile Atlantic Salmon?
Delaval, Aurelien Nicolas; Solås, Martine Røysted; Skoglund, Helge; Salvanes, Anne Gro Vea (Journal article; Peer reviewed, 2021)Sagittal otoliths are calcareous structures in the inner ear of fishes involved in hearing and balance. They are usually composed of aragonite; however, aragonite can be replaced by vaterite, a deformity which is more ... -
Domesticated escapees on the run: The second-generation monitoring programme reports the numbers and proportions of farmed Atlantic salmon in >200 Norwegian rivers annually
Glover, Kevin; Urdal, Kurt; Næsje, Tor; Skoglund, Helge; Florø-Larsen, Bjørn; Otterå, Håkon Magne; Fiske, Peder; Heino, Mikko Petteri; Aronsen, Tonje; Sægrov, Harald; Diserud, Ola Håvard; Barlaup, Bjørn Torgeir; Hindar, Kjetil; Bakke, Gunnar O; Solberg, Ingrid; Lo, Håvard; Solberg, Monica Favnebøe; Karlsson, Sten; Skaala, Øystein; Lamberg, Anders; Kanstad-Hanssen, Øyvind; Muladal, Rune; Skilbrei, Ove Tommy; Wennevik, Vidar (Peer reviewed; Journal article, 2019)Norway is the world’s largest producer of farmed Atlantic salmon and is home to ∼400 rivers containing wild salmon populations. Farmed escapees, a reoccurring challenge of all cage-based marine aquaculture, pose a threat ... -
Effects of nuisance submerged vegetation on the fauna in Norwegian rivers
Velle, Gaute; Skoglund, Helge; Barlaup, Bjørn Torgeir (Journal article; Peer reviewed, 2021)The abundance of aquatic vegetation is increasing in rivers and lakes worldwide. The aim of this study was to find how the macrophyte Juncus bulbosus Linnaeus affects salmonids and benthic macroinvertebrates in Norwegian ... -
Swimming with the fishes: validating drift diving to identify farmed Atlantic salmon escapees in the wild
Mahlum, Shad Kenneth; Skoglund, Helge; Wiers, Tore; Norman, Eirik; Barlaup, Bjørn Torgeir; Wennevik, Vidar; Glover, Kevin; Urdal, Kurt; Bakke, Gunnar O; Vollset, Knut (Peer reviewed; Journal article, 2019)Escaped farmed Atlantic salmon Salmo salar interbreeding with wild conspecifics represents a threat to the genetic integrity and viability of wild populations. Therefore, it is necessary to accurately quantify escapees in ...
