Additive effects of enhanced ambient ultraviolet B radiation and increased temperature on immune function, growth and physiological condition of juvenile (parr) Atlantic Salmon, Salmo salar
(Journal article; Peer reviewed, 2010-09-29)Climate change models predict increased ultraviolet B (UVB) radiation levels due to stratospheric ozone depletion and global warming. In order to study the impact of these two environmental stressors acting simultaneously ... -
Anaesthesia of Atlantic halibut (Hippoglossus hippoglossus) – Effect of pre-anaesthetic sedation, and importance of body weight and water temperature
(Journal article; Peer reviewed, 2010-11-30)The efficacy of the anaesthetic agents benzocaine, metacaine (MS-222), metomidate, 2-phenoxyethanol, quinaldine and isoeugenol was studied in Atlantic halibut (Hippoglossus hippoglossus). Fish with an average body weight ... -
Disease interaction and pathogens exchange between wild and farmed fish populations with special reference to Norway
(Journal article; Peer reviewed, 2011-05-21)Norway has the largest salmon-farming industry in the world, an industry that is still growing, and in recent years production of marine species like Atlantic cod has also increased. At the same time, Norway has the world's ... -

Effects of different modified diets on growth, digestive enzyme activities and muscle compositions in juvenile Siamese fighting fish (Betta splendens Regan, 1910)
(Journal article; Peer reviewed, 2011-10-12)The effects of four modified diets (gamma-irradiated, microwave-irradiated, probiotic-supplemented and carbohydrase-supplemented diets) were studied on digestive enzyme specific activities and growth performance quality ... -
Effects of UV Radiation and Diet on Polyunsaturated Fatty Acids in the Skin, Ocular Tissue and Dorsal Muscle of Atlantic Salmon (Salmo salar) Held in Outdoor Rearing Tanks
(Journal article; Peer reviewed, 2010-07)The effect of UV radiation (UVR) on juvenile Atlantic salmon (Salmo salar) was assessed by measuring the fatty acid (FA) profiles of muscle, dorsal and ventral skin, and ocular tissues following 4-month long exposures to ... -
Effects of vegetable feed ingredients on bone health in Atlantic salmon
(Journal article; Peer reviewed, 2010-04)The aim of the present study was to examine if dietary inclusion of vegetable lipids (VL) and proteins (VP) influenced markers of bone health in Atlantic salmon. Triplicate groups were fed one of four different diets; 100% ... -
Evaluating bioencapsulation of florfenicol in rotifers (Brachionus plicatilis)
(Journal article; Peer reviewed, 2010-11-11)The rotifer Brachionus plicatilis is one of the most important live-feed organisms used in the larval culture of marine fish. Bioencapsulation of florfenicol in rotifers was investigated by delivering it directly to the ... -
Feeding preference of recaptured Atlantic salmon Salmo salar following simulated escape from fish pens during autumn
(Journal article; Peer reviewed, 2010-12-21)Escapes of farmed fish from coastal farms around the world are believed to have genetic and ecological consequences for wild fish populations. Each year there are numerous escapes of adult farmed Atlantic salmon Salmo ... -
Fluctuating sea-cage environments modify the effects of stocking densities on production and welfare parameters of Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2011-05-21)Stocking densities are commonly used to set limits for the production of fish in sea-cages, yet limited information exists to assess how environmental fluctuations modify the effects of stocking densities on the production ... -
Mechanisms regulating oocyte recruitment and skippedspawning in Northeast Arctic cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2009-09)To examine mechanisms that affect fecundity, atresia and skipped spawning in Northeast Arctic cod (Gadus morhua L.), we conducted an experiment where wild-caught cod (>60 cm) kept under restricted food regimes were subjected ... -
MMP-13 (Matrix MetalloProteinase 13) expression might be an indicator for increased ECM remodeling and early signs of vertebral compression in farmed Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2010-04)Vertebral body compression is a common problem in commercial farming of Atlantic salmon. Although risk factors, such as vaccination and alnutrition, have been identified, the etiology is largely unknown. Histological studies ... -
Mortality of mackerel (Scomber scombrus L.) after pursing and slipping from a purse seine
(Journal article; Peer reviewed, 2010-10)A new method was used to study the effect of crowding and subsequent slipping from a purse seine on the mortality of Atlantic mackerel (Scomber scombrus L.). Mackerel were allowed to swim from a purse seine through a ... -

Tenacibaculum sp. associated with winter ulcers in sea-reared Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2011-05-09)Coldwater-associated ulcers, i.e. winter ulcers, in seawater-reared Atlantic salmon Salmo salar L. have been reported in Norway since the late 1980s, and Moritella viscosa has been established as an important factor in ... -
Viral Haemorrhagic Septicemia (VHS) in wild and farmed fish in Norwegian waters
(Conference object, 2011-05)Viral Haemorrhagic septicaemia viruses (VHSV) are isolated from 82 different fish species and are globally spread in freshwater as well as marine environments. The virus can cause disease outbreaks both in wild and ... -
Welfare of aquatic organisms: Is there some faith-based HARKing going on here?
(Journal article; Peer reviewed, 2011-05-09)Much of the literature on aquatic animal welfare is flawed by 4 non-mutually exclusive (and often inter-related) biases: under-reporting/ignoring of negative results, faith-based research and/or interpretations, Hypothesizing ...
