Effect of levels and sources of dietary manganese on growth and mineral composition of post-smolt Atlantic salmon fed low fish meal, plant-based ingredient diets
(Peer reviewed; Journal article, 2019-10-15)The impact of dietary manganese (Mn) levels and sources on the growth and mineral composition of post-smolt Atlantic salmon (Salmo salar) fed practical diets was studied. Seven experimental diets were prepared with graded ... -
The effects of cryogenically preserved sperm on the fertilization, embryonic development and hatching success of lumpfish C. lumpus
(Journal article; Peer reviewed, 2022)Lumpfish (C. lumpus) are used as cleaner fish in the Atlantic salmon (Salmo salar) farming industry to remove parasitic sea lice. At present, wild lumpfish broodstock are used which puts strain on wild populations. By ... -
Effects of different feeding regimes on growth, cataract development, welfare, and histopathology of lumpfish (Cyclopterus lumpus L.)
(Journal article; Peer reviewed, 2024)To develop specific recommendations on the feeding strategies for farmed lumpfish, four duplicate groups (n = 70; N = 280) of lumpfish with a mean ± SD start weight of 30.4 ± 5.3 g were distributed among eight sea cages ... -
Environmentally driven changes in Atlantic salmon oxidative status interact with physiological performance
(Journal article; Peer reviewed, 2024)Farmed Atlantic salmon in sea cages experience natural seasonal changes in seawater temperature and photoperiod. Atlantic salmon have more oxidized tissues in spring and early summer, and this corresponds to the period of ... -
Evaluation of photodegradable chitin synthetase inhibitors for the treatment of salmon lice (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2023)Some photolabile ethanolamine analogues of the chitin synthetase inhibitors diflubenzuron, teflubenzuron, and lufenuron were tested for activity as anti-lice compounds towards salmon lice (Lepeophtheirus salmonis). Two ... -
Exploring the impact of thermal delousing on gill health and microbiome dynamics in farmed Atlantic Salmon
(Journal article; Peer reviewed, 2024)The economic cost of salmon louse (Lepeophtheirus salmonis and Caligus rogercresseyi) infestations in the Atlantic salmon (Salmo salar) industry has been estimated to be around $900 million annually. This high cost has ... -
Exposure to cold temperatures differentially modulates neural plasticity and stress responses in post-smolt Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2022)The transfer success of farmed post-smolt Atlantic salmon (Salmo salar) to sea-cages rely on neural adaptions to promote stress resilience. As low temperatures impact physiology, this suggests that off-season transfer to ... -
First isolation, identification and characterisation of Tenacibaculum maritimum in Norway, isolated from diseased farmed sea lice cleaner fish Cyclopterus lumpus L
(Peer reviewed; Journal article, 2016-06-23)The use of cleaner fish as biological controls of salmon lice (Lepeophtheirus salmonis) has increased exponentially in the last decade in Norwegian Atlantic salmon (Salmo salar) production. This alternative to chemical ... -
Freshwater history influences farmed Atlantic salmon (Salmo salar) performance in seawater
(Journal article; Peer reviewed, 2024)The quality of smolts is one of the key factors for successful salmon production. We compared growth performance, physiological traits, and environmental adaptation in Atlantic salmon (Salmo salar) after transfer into a ... -
Host associated genotypes in the family Branchiomonaceae with proposal of Ca. Branchiomonas mykissicola n. sp. from rainbow trout (Oncorhynchus mykiss)
(Journal article; Peer reviewed, 2024)Candidatus Branchiomonas cysticola is the primary etiological agent of epitheliocystis and the most prevalent bacterium associated with gill disease (GD) in farmed Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus ... -
Hypoxia tolerance thresholds for post-smolt Atlantic salmon: Dependency of temperature and hypoxia acclimation
(Journal article, 2013-12-05)Atlantic salmon (Salmo salar L.) experience periodic drops in dissolved oxygen (O2) inside aquaculture sea cages. In order to evaluate whether fish function or welfare is compromised during such drops in O2 (termed hypoxia), ... -
Impact of fish density and specific water flow on skin properties in Atlantic salmon (Salmo salar L.) post-smolts
(Peer reviewed; Journal article, 2016)Prolonged production of Atlantic salmon (Salmo salar) post-smolts in closed-containment systems has prompted research into biological requirements under higher production intensities. This study examined the effect of fish ... -
Impact of long-term fasting on the stomach-hypothalamus appetite regulating genes in Atlantic salmon postsmolts
(Journal article; Peer reviewed, 2023)Atlantic salmon will experience periods of fasting during its lifecycle. In nature, prolonged fasting periods occur owing to seasonal fluctuations in available feeds, migration or in relation to reproduction. In a culture ... -
Increasing the levels of the essential trace elements Se, Zn, Cu and Mn in rotifers (Brachionus plicatilis) used as live feed
(Peer reviewed; Journal article, 2013-03-04)Rotifers are a common first feeding diet for rearing marine fish larvae. However, the levels of Mn, Cu, Zn, Se and iodine found in rotifers are low and may be insufficient to meet larval fish requirements. This study ... -
Induction of tenacibaculosis in Atlantic salmon smolts using Tenacibaculum finnmarkense and the evaluation of a whole cell inactivated vaccine
(Peer reviewed; Journal article, 2018-10)Tenacibaculosis, an ulcerative disease characterised by skin lesions, mouth erosion, frayed fins and tail rot, is a significant fish welfare issue in marine aquaculture worldwide. The disease is a concern to the Atlantic ... -
Influence of salinity on rainbow trout (Oncorhynchus mykiss) smolt development and postsmolt performance
