Effect of feed ingredients on nutrient digestibility, waste production and physical characteristics of rainbow trout (Oncorhynchus mykiss) faeces.
(Peer reviewed; Journal article, 2023)This study assessed the effect of different dietary ingredients on the quantity and characteristics of faecal waste produced by rainbow trout (Oncorhynchus mykiss). Seven ingredients were tested: fish meal (FM), mussel ... -
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
(Journal article; Peer reviewed, 2019)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 effect of temperature on the survival of salmonid alphavirus analysed using in vitro and in vivo methods
(Peer reviewed; Journal article, 2020)Disease outbreaks in fish aquaculture are often of concern due to the possibility of pathogen transmission to fish in neighbouring farms and to wild fish populations. To be able to assess the risk and manage transmission ... -
Effect of water temperature and exposure duration on detachment rate of salmon lice (Lepeophtheirus salmonis); testing the relevant thermal spectrum used for delousing
(Peer reviewed; Journal article, 2023)Thermal delousing has become the most applied method for treatment against salmon lice. However, the temperature range used is strongly aversive for salmonids, and the method is associated with increased mortality. Treatment ... -
Effects of dietary vitamin D3 levels on survival, mineralization, and skeletal development of gilthead seabream (Sparus aurata) larvae
(Peer reviewed; Journal article, 2022)Vitamin D is an essential fat soluble micronutrient that helps in growth, bone development, calcium homeostasis and other metabolic process. The study on effect of vitamin D3 in marine fish larvae were very scarce irrespective ... -
Effects of the dietary supplementation of copper on growth, oxidative stress, fatty acid profile and skeletal development in gilthead seabream (Sparus aurata) larvae
(Peer reviewed; Journal article, 2023)The effect of dietary copper (Cu) levels on growth, oxidative stress, fatty acid profile and bone health of gilthead seabream larvae (Sparus aurata) was studied in 47 days-post-hatching fish fed 4 experimental diets ... -
Effects of vitamin D3 supplementation in gilthead seabream (Sparus aurata) juveniles fed diets high in plant based feedstuffs
(Peer reviewed; Journal article, 2021)Modern aquaculture feeds tend to contain lower levels of fish based ingredients, while increasing the content of plant ingredients. However, this may alter the vitamin profile of the feeds, leading to unbalanced vitamin ... -
Efficiency and welfare impact of long-term simultaneous in situ management strategies for salmon louse reduction in commercial sea cages
(Peer reviewed; Journal article, 2020)The Atlantic salmon (Salmo salar) aquaculture industry is faced with an obstacle in sustainability with increasing production, which is the control and prevention of the ectoparasitic salmon louse Lepeophtheirus salmonis. ... -
Environmentally responsive parasite prevention halves salmon louse burden in commercial marine cages
(Peer reviewed; Journal article, 2023)Though a naturally occurring species throughout the Atlantic, parasitic salmon louse (Lepeophtheirus salmonis) population dynamics are increasingly intertwined with salmonid aquaculture. In contrast to reactive louse ... -
Family differences on triploid induction, sexual maturation and its contribution to sea cage performance of Atlantic cod, Gadus morhua
(Journal article; Peer reviewed, 2019)Early maturation has been one of the biological bottlenecks of commercializing Atlantic cod culture. To overcome the bottleneck, production of sterile fish through triploidy and other molecular techniques have been suggested ... -
Full compensatory growth before harvest and no impact on fish welfare in Atlantic salmon after an 8-week fasting period
(Peer reviewed; Journal article, 2021)Individually tagged Atlantic salmon postsmolts (≈1200 g, 46 cm) reared in triplicate indoor holding tanks were fasted for 8 weeks at 12 °C and subsequently refed for 5 weeks, whereafter they were transferred to triplicate ... -
Full production cycle performance of gene-edited, sterile Atlantic salmon - growth, smoltification, welfare indicators and fillet composition
(Peer reviewed; Journal article, 2022)Using germ cell-free (GCF), sterile, dnd-knockout salmon for farming could solve the problems associated with precocious maturation and genetic introgression of farmed breeds into wild populations. However, prior to using ... -
Full production cycle, commercial scale culture of salmon in submerged sea-cages with air domes reduces lice infestation, but creates production and welfare challenges
(Peer reviewed; Journal article, 2021)Structural modification of sea cages is continually changing to counter major production issues associated with commercial salmon farming. For example, snorkels and skirts are added to cages to reduce salmon lice infestations, ... -
Heart rate bio-loggers as welfare indicators in Atlantic salmon (Salmo salar) aquaculture
(Peer reviewed; Journal article, 2020)In this study, 12 farmed Atlantic salmon (~1200 g) were tagged with commercially available heart rate (HR) bio-loggers and maintained in a controlled fish tank laboratory environment at 9 °C on a 12 h day/night cycle for ... -
Impact of dietary zinc and seawater transfer on zinc status, availability, endogenous loss and osmoregulatory responses in Atlantic salmon smolt fed low fish meal feeds
(Peer reviewed; Journal article, 2022)Atlantic salmon fed low fish meal feeds supplemented with zinc (Zn) were studied in two feeding trials. In trial I, Atlantic salmon parr were fed six graded Zn levels (40 to 249 mg kg−1 as ZnSO4) for 8 weeks in freshwater ... -
Impact of long-term fasting on the stomach-hypothalamus appetite regulating genes in Atlantic salmon postsmolts
(Peer reviewed; Journal article, 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 ... -
Improving scallop (Pecten maximus and Placopecten magellanicus) spat production by initial larvae size and hydrodynamic cues used in nursery system
(Journal article; Peer reviewed, 2019)There are several factors affecting scallops during the metamorphosis process that could explain the relatively low post-larvae yield observed in hatcheries. Competent bivalve larvae respond to different settlement cues ... -
Increasing the dietary n-6/n-3 ratio alters the hepatic eicosanoid production after acute stress in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Earlier studies have indicated that a high inclusion of n-6 fatty acids (FA) in feeds for Atlantic salmon can affect the stress response. To test this hypothesis, Atlantic salmon (Salmo salar) were fed diets containing ... -
