Can lipidomics help identifying egg quality in ballan wrasse?
(Peer reviewed; Journal article, 2022)Ballan wrasse (Labrus bergylta) is in the limelight of aquaculture research due to the species role as cleaner fish in salmon aquaculture. A major drawback is that the salmon industry still depends on wild caught fish as ... -
Effect of dietary ARA/EPA/DHA ratios on growth performance and intermediary metabolism of gilthead sea bream (Sparus aurata) juveniles
(Peer reviewed; Journal article, 2019)Vegetable oils (VO) are generally accepted as valuable alternatives to fish oils but are devoid of n-3 LC-PUFA (Long-Chain-Polyunsaturated Fatty Acids) and rich in C18-PUFA. Marine fish have limited capacity to express ... -
Effects of reduced organic matter loading through membrane filtration on the microbial community dynamics in recirculating aquaculture systems (RAS) with Atlantic salmon parr (Salmo salar)
(Peer reviewed; Journal article, 2020)A key challenge in recirculating aquaculture systems (RAS) is the accumulation of particulate organic matter, especially the fine and colloidal fraction due to low removal efficiency of today's technology. The supply of ... -
First feed matters: The first diet of larval fish programmes growth, survival, and metabolism of larval ballan wrasse (Labrus bergylta)
(Peer reviewed; Journal article, 2022)The use of cleaner fish, such as the ballan wrasse (Labrus bergylta), is important for combatting the sea lice problem in salmonid cage farming. Ballan wrasse is the only wrasse species that is cultivated, though only about ... -
Growth and nutritional composition of the polychaete Hediste diversicolor (OF Müller, 1776) cultivated on waste from land-based salmon smolt aquaculture
(Journal article; Peer reviewed, 2019)Increased aquaculture production will result in increased amounts of waste produced, and these wastes are highly underexploited. Polychaetes might effectively consume such waste and transfer them into compounds as marine ... -
Heart rate and swimming activity as stress indicators for Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)We investigated the relationship between telemetry measurements of heart rate and swimming activity and the physiological status in farmed Atlantic salmon (Salmo salar) to assess the potential to use telemetry measurements ... -
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 ... -
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 ... -
Oocyte and egg quality indicators in European eel: lipid droplet coalescence and fatty acid composition.
(Journal article; Peer reviewed, 2018)During European eel assisted reproduction, timely administration of hormones that induce oocyte maturation and ovulation is a major factor influencing subsequent egg quality. This treatment commonly comprises one injection ... -
Ova lipid profiling and egg quality in wild and captive lumpfish, Cyclopterus lumpus (Linnaeus, 1758)
(Peer reviewed; Journal article, 2022)Lumpfish (Cyclopterus lumpus) serves an important role as cleaner fish for removing salmon lice in salmon aquaculture. For this use, cultivated lumpfish are preferred over wild-caught fish to avoid overexploitation of ... -
Physiological changes observed in farmed Atlantic salmon (Salmo salar L.) with nephrocalcinosis
(Peer reviewed; Journal article, 2022)There is a growing concern for fish health and welfare in the salmon industry in Norway. Nephrocalcinosis, described as mineral deposits within the kidney, is increasingly observed. However, little is known about its ... -
Transcriptional regulation of lipid metabolism when salmon fry switches from endogenous to exogenous feeding
(Journal article; Peer reviewed, 2018)The onset of first feeding is a critical period for Atlantic salmon (Salmo salar). The fish goes through a dramatic transition, from using the yolk sac as an energy and nutrient resource to rely on exogenous food. However, ... -
Triploid Atlantic salmon × brown trout hybrids have similar seawater growth and welfare issues as triploid Atlantic salmon, but both were heavier at harvest than their diploid counterparts
(Peer reviewed; Journal article, 2022)Interspecific hybridisation may improve the farm performance of sterile triploid salmonids via heterosis (i.e. hybrid vigour). We assessed growth over the final 293 days in seawater, and harvest quality, in diploid and ... -
Under the sea: How can we use heart rate and accelerometers to remotely assess fish welfare in salmon aquaculture?
(Peer reviewed; Journal article, 2023)Recent advances in bio-sensing technologies open for new possibilities to monitor and safeguard the welfare of fishes in aquaculture. Yet before taken into practice, the applicability of all novel biosensors must be ...
