A comparative study of organic- versus conventional Atlantic salmon. II. Fillet color, carotenoid- and fatty acid composition as affected by dry salting, cold smoking and storage
(Journal article, 2016)The aim of the present study was to investigate the effect of dry salting, cold smoking and 14 days refrigerated storage at 4 °C on the stability of carotenoids, color and fatty acids in commercially reared organic Atlantic ... -
A comparative study of organic- versus conventional farmed Atlantic salmon. I. Pigment and lipid content and composition, and carotenoid stability in ice-stored fillets
(Journal article, 2016)The aim of the present study was to investigate retention of pigments and composition of fatty acids (FA) in farmed organic- and conventional Atlantic salmon fed commercial feed adapted to organic and conventional salmon ... -
A comparative study on quality, shelf life and sensory attributes of Atlantic salmon slaughtered on board slaughter vessels against traditional land-based facilities.
(Peer reviewed; Journal article, 2021)The purpose of this study was to investigate the shelf life and quality of Atlantic salmon (Salmo salar) slaughtered onboard vessels and shipped to Denmark in −0.8 °C refrigerated seawater (RSW) as compared to traditional ... -
A comparison of two seawater adaptation strategies for Atlantic salmon post-smolt (Salmo salar) grown in recirculating aquaculture systems (RAS): Nitrification, water and gut microbiota, and performance of fish
(Peer reviewed; Journal article, 2021)The land-based production phase in Norwegian Atlantic salmon farming has the past years been extended to include post-smolt for an increasing number of farmers. Post-smolt production can involve introduction of brackish/seawater ... -
Effect of chilling technologies on water holding properties and other quality parameters throughout the whole value chain: From whole fish to cold-smoked fillets of Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)The effect of different chilling technologies on water holding and quality parameters was investigated on Atlantic salmon throughout the entire value chain. Chilling technologies of whole fish before filleting, included ... -
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 ... -
Extraction, partial purification and characterization of alkaline protease from rainbow trout (Onchorhynchus Mykiss) viscera
(Journal article; Peer reviewed, 2019)In this study, crude alkaline proteases were recovered from rainbow trout (Oncorhynchus mykiss) viscera and partially purified by use of different saturation of ammonium sulfate. The enzyme exhibited highest yield, purity ... -
Long-term microbial community structures and dynamics in a commercial RAS during seven production batches of Atlantic salmon fry (Salmo salar)
(Peer reviewed; Journal article, 2023)The microbiota of recirculating aquaculture systems (RAS) is of major importance for optimal fish health. However, the microbial communities in commercial RAS are highly complex and more knowledge is needed to potentially ... -
Management of biofloc concentrations as an ecological strategy for microbial control in intensive shrimp culture
(Peer reviewed; Journal article, 2021)This study investigated if the intensity of sedimentation through settling tanks modifies the bacterial community composition of biofloc systems and affects performance of shrimp. A 50-day trial, which was conducted with ... -
Microbial community dynamics in a commercial RAS for production of Atlantic salmon fry (Salmo salar)
(Peer reviewed; Journal article, 2022)Recirculating aquaculture systems (RAS) harbour complex microbial communities which can have an impact on the growth and development of the reared fish. This study aimed to improve our understanding of microbial community ... -
Microbial water quality of the copepod Acartia tonsa in cultures for use as live feed
(Peer reviewed; Journal article, 2022)Live feed is important for rearing of marine larvae in the aquaculture industry and copepods have shown some superior qualities compared to Artemia and rotifers. Whereas the nutritional composition is one factor contributing ... -
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 ... -
Production of lumpfish (Cyclopterus lumpus L.) in RAS with distinct water treatments: Effects on fish survival, growth, gill health and microbial communities in rearing water and biofilm
(Peer reviewed; Journal article, 2020)Lumpfish (Cyclopterus lumpus L.) in Norway is currently produced in traditional flow-through systems (FTS). Hatcheries frequently show signs of bacterial infections, unstable microbial communities in the rearing water and ... -
Production of lumpfish in RAS with distinct water treatments: Effects on fish survival, growth, gill health and microbial communities in rearing water and biofilm
(Peer reviewed; Journal article, 2020)Lumpfish in Norway is currently produced in traditional flow-through systems (FTS). Hatcheries frequently show signs of bacterial infections, unstable microbial communities in the rearing water and varying mortality. ... -
Seeding as a start-up strategy for improving the acclimation of freshwater nitrifying bioreactors to salinity stress
(Peer reviewed; Journal article, 2021)Recirculating aquaculture systems (RAS) for anadromous fish such as salmonids often require salinity changes during the production cycle. However, high or variable salinity can disrupt the biological nitrification process, ... -
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, ...
