Interaction of temperature and photoperiod on male postsmolt maturation of Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2023)Maturation of Atlantic salmon male postsmolts is a concern in aquaculture due to its increasing occurrence under intensive rearing conditions and its negative impact on growth, welfare and seawater readiness. The effect ... -
Intestinal health in Atlantic salmon post-smolt (Salmo salar) when fed low- and high HUFA diets
(Peer reviewed; Journal article, 2022)It is well established that farmed Atlantic salmon (Salmo salar) need n3-highly unsaturated fatty acids (HUFA) in their diet to thrive and grow. However, the biological functions to the individual HUFAs may differ, implying ... -
Long term effects of smolt production strategy and early seawater phase rearing environment on mortality, growth, sexual maturation, and vertebra deformities in farmed Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2023)The life history of Atlantic salmon is plastic and determined by factors such as daylength and temperature. In aquaculture, artificial long days during smolt production maximize growth and allows for early sea-transfer, ... -
Long-term welfare effects of repeated warm water treatments on Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Warm water treatment has in recent years become widely used for ridding salmonids of sea lice in aquaculture although the consequences of the treatment for fish welfare are not adequately investigated. The objective of ... -
Low intestinal inflammation model (HP48) in Atlantic salmon (Salmo salar) and inflammatory mitigation by Bactocell
(Peer reviewed; Journal article, 2022)Moderate levels of intestinal damage and inflammation are often seen in intensive fish aquaculture. The causes may be due to antinutrients from plant meals, stress or other causes. There is currently a lack of good models ... -
Lumpfish Cyclopterus lumpus reproduction: Pituitary gene expression, physiological and morphological changes accompanying gonadal maturation
(Peer reviewed; Journal article, 2022)Lumpfish is the most important cleanerfish species in Atlantic salmon farming. Detailed information on the gonadal maturation process is a prerequisite for year-round production of juvenile lumpfish. In the present study ... -
The metabolic rate response to feed withdrawal in Atlantic salmon post-smolts
(Peer reviewed; Journal article, 2020)Feed withdrawal is a widespread practice in Atlantic salmon (Salmo salar) aquaculture to empty the gut prior to major farming operations, while certain pathogens and suboptimal environmental conditions in production cages ... -
Ossification of Atlantic cod (Gadus morhua) – Developmental stages revisited
(Peer reviewed; Journal article, 2017)In studies of marine larvae, it is common to use days post-hatch as a developmental reference point. We show that age is a poor measure of morphological and physiological development in Atlantic cod. Therefore, we propose ... -
Pharmacokinetics of florfenicol in lumpfish (Cyclopterus lumpus L.) after a single oral administration
(Journal article; Peer reviewed, 2019)Farming of lumpfish for biological removal of sea lice from farmed Atlantic salmon has expanded rapidly in Europe and Canada over the last 5–6 years and the lumpfish has become an economically important species. There are, ... -
Physiological responses of farmed Atlantic salmon and two cohabitant species of cleaner fish to progressive hypoxia
(Journal article; Peer reviewed, 2019)To mitigate salmon lice infestations in Atlantic salmon (Salmo salar) sea cages, deployment of cleaner fish have become a widespread strategy. However, species of cleaner fish may experience poor welfare in the highly ... -
Potential of insect-based diets for Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2018)In the present study, we aimed to assess the effect of dietary insect meal (IM) and insect oil (IO) on growth performance, body composition and nutrient digestibility of freshwater reared Atlantic salmon. The IM and IO ... -
Prediction of goldsinny wrasse (Ctenolabrus rupestris) minimum size required to avoid escape through salmon (Salmo salar) farm nets
(Peer reviewed; Journal article, 2021)The salmon (Salmo salar) aquaculture industry has used various practices to treat salmon louse (Lepeophtheirus salmonis) infections, including mechanical, thermal, and chemical treatments. However, due to the environmental ... -
Revisiting ecological carrying capacity indices for bivalve culture
(Peer reviewed; Journal article, 2023)Ecological carrying capacity (ECC) indices for bivalve culture rely on key ecosystem turnover rates: 1. clearance time (CT), the time needed for the cultured bivalves to filter the entire bay volume; 2. renewal time (RT), ... -
Rib abnormalities and their association with focal dark spots in Atlantic salmon fillets
(Peer reviewed; Journal article, 2022)Focal dark spots (DS) represent the most common quality problem in farmed Atlantic salmon (Salmo salar L.). DS are predominantly located in the cranio-ventral region of the fillet, that is characterized by the presence of ... -
Safe limits of selenomethionine and selenite supplementation to plant-based Atlantic salmon feeds
(Journal article; Peer reviewed, 2018)The use of plant-based feeds warrants the supplementation with selenium (Se) to cover the requirement for Atlantic salmon. Depending on its chemical form, Se is a trace element with a narrow range between requirement and ... -
Salinity and temperature alter the efficacy of salmon louse prevention
(Peer reviewed; Journal article, 2023)Several promising preventive tools and strategies have been developed to combat infestation of salmon in marine cages by parasitic salmon lice. While most of the prevention strategies tested have significantly reduced louse ... -
Salmon lice dispersal and population model for management strategy evaluation
(Peer reviewed; Journal article, 2023)Modern marine salmon aquaculture includes management of salmon lice (Lepeophtheirus salmonis) infestations. Moving from a reactive delousing treatment effort to a proactive preventive strategy requires a simulation tool ... -
'Snorkel' sea lice barrier technology reduces sea lice loads on harvest-sized Atlantic salmon with minimal welfare impacts
(Journal article; Peer reviewed, 2016-02-13)The infestation of farmed Atlantic salmon (Salmo salar) by ectoparasitic sea lice (Lepeophtheirus salmonis) presents a need for new approaches to parasite control. One option is the use of ‘snorkel’ sea lice barrier ... -
Spawning manipulation, broodfish diet feeding and egg production in farmed Atlantic salmon
(Peer reviewed; Journal article, 2024)Atlantic salmon aquaculture relies on continuous supply of high quality eggs. Broodfish nutrition and manipulation of ovulation time (photoperiod and temperature) are key factors. The optimum feeding period with broodfish ... -
