Analysing mortality patterns in salmon farming using daily cage registrations
Persson, David Weman; Nødtvedt, Ane C. W.; Aunsmo, Arnfinn; Stormoen, Marit (Journal article; Peer reviewed, 2021) -
Early warning through video monitoring: Dissolved hydrogen sulphide (H2S) affects Atlantic salmon swimming behavior in recirculating aquaculture systems
Ciani, Elia; Kvæstad, Bjarne; Stormoen, Marit; Mayer, Ian; Gupta, Shruti; Ribicic, Deni; Netzer, Roman (Peer reviewed; Journal article, 2024)Hydrogen sulphide (H2S) poses a major threat in marine land-based recirculating aquaculture systems (RAS) leading to acute mortality in sensitive fish species such as Atlantic salmon (Salmo salar). To date, little is known ... -
Effekten av turbiditet i RAS-anlegg på gjellehelse målt i antall slimceller i gjellene hos atlantisk laks i settefiskproduksjon
Figenschou, Alexander J. Hat.; Hillestad, Linn-Anett (Student paper, others, 2019)I dette studiet ble det studert sammenhengen mellom turbiditet og antall slimceller i gjellene til atlantisk laks. Hypotesen var at høy turbiditet (og dermed lav siktdybde i vannkarene) i RAS-anlegg kan føre til økt mekanisk ... -
Evaluating the potential for sea lice to evolve freshwater tolerance as a consequence of freshwater treatments in salmon aquaculture
Groner, Maya L.; Laurin, Emilie; Stormoen, Marit; Sanchez, Javier; Fast, Mark D.; Revie, Crawford W. (Journal article; Peer reviewed, 2019)Increasing usage of non-medicinal methods (NMMs) to control sea louse infestations on salmon farms has raised questions about whether sea lice may be able to evolve tolerance of NMMs. Of particular concern is the potential ... -
Factors influencing production loss in salmonid farming
Pincinato, Ruth Beatriz; Asche, Frank; Bleie, Hogne; Skrudland, Aud; Stormoen, Marit (Peer reviewed; Journal article, 2020)Using a unique dataset, this paper investigates factors influencing production loss in Norwegian salmonid farming. The factors can be grouped into fish-specific factors (e.g. species, genetics, and generation), input factors ... -
Gill infections, gill pathology and gill-related mortality in farmed Atlantic salmon
Østevik, Liv (PhD Thesis;2022:69, Doctoral thesis, 2022)Last year (2021) 54 million Atlantic salmon died at Norwegian food producing sea sites. This constitutes a loss of 15,5% of the fish that were transferred to sea. Gill diseases are among the health issues that causes ... -
Managing the Dissolved Oxygen Balance of Open Atlantic Salmon Sea Cages: A Narrative Review
Berntsson, Evelina Veronica Christina; Stevik, Tor Kristian; Bergheim, Asbjørn; Persson, David Weman; Stormoen, Marit; Liland, Kristian Hovde (Peer reviewed; Journal article, 2024) -
Monitoring fish health : a vital part of salmon farming management
Persson, David Weman (PhD Thesis;2023:4, Doctoral thesis, 2023)Mortality represents a major challenge in the salmon farming industry. In Norway the mortality in the marine phase of the salmon production cycle has been 15-20% annually the recent years. This situation is not sustainable ... -
Piscine orthoreovirus : genetic variants and virulence
Vatne, Nina Askim (PhD Thesis;2024:16, Doctoral thesis, 2024)Piscine orthoreovirus (PRV) is a virus of salmonids. It is widespread and the causative agent of Heart and Skeletal Muscle Inflammation (HSMI) in farmed Atlantic salmon (Salmo salar). Different variants of PRV-1 differ in ... -
Sårhelingsdynamikk hos sjøsatt atlantisk Laks (Salmo salar)
Hausken-Hauge, Agnes (Student paper, others, 2024)Sårhelse er et stort økonomisk og fiskevelferdsmessig problem i oppdrettsnæringen. I denne studien har vi sett på en liten del av sårdelingsdynamikken hos sjøtatt atlantisk oppdrettslaks i Norge. Studien er gjennomført ... -
A stepwise integrated risk-assessment framework in aquaculture: the case of sea lice tolerance to freshwater treatments on salmon farms.
Laurin, Emilie; Stormoen, Marit; Revie, Crawford W.; Javier, Sánchez-Hernández (Peer reviewed; Journal article, 2020)Aquaculture studies are often faced with data limitations when carrying out a quantitative risk assessment. Consolidating results from a literature search of potentially applicable methods, we propose a stepwise integrated ... -
The economic impact of decreased mortality and increased growth associated with preventing, replacing or improving current methods for delousing farmed Atlantic salmon in Norway
Walde, Cecilie Sviland; Jensen, Britt Bang; Stormoen, Marit; Asche, Frank; Misund, Bård; Pettersen, Jostein Mulder (Peer reviewed; Journal article, 2023) -
Variations in mucous cell numbers in gills of Atlantic salmon (Salmo salar) presmolt in commercial freshwater farms in Norway
Persson, David Erik Ludvig; Bjørgen, Håvard; Figenschou, Alexander Joachim Hatchek; Hillestad, Linn-Anett; Koppang, Erling Olaf; Nødtvedt, Ane C. W.; Stormoen, Marit (Peer reviewed; Journal article, 2020)Fish gills are heavily exposed to the external milieu and may react against irritants with different cellular responses. We describe variations in mucous cell counts in gills from healthy Atlantic salmon (Salmo salar) ... -
What is the value of a dead fish? : the biological and economic impact of delousing farmed Atlantic salmon in Norway
Walde, Cecilie Sviland (PhD Thesis;2023:61, Doctoral thesis, 2023)The impacts of the ectoparasite salmon lice (Lepeoptheirus salmonis (Krøyer, 1837)), is a major challenge for sustainable production of farmed Atlantic salmon (Salmo salar) in Norway, and has been so for over 40 years. ...
