Effects of chitin synthesis inhibitor treatment on Lepeophtheirus salmonis (Copepoda, Caligidae) larvae
(Peer reviewed; Journal article, 2019-09-23)The salmon louse (Lepeophtheirus salmonis) is an ectoparasite infecting Atlantic salmon (Salmo salar), which causes substantial problems to the salmon aquaculture and threatens wild salmon. Chitin synthesis inhibitors ... -
Effects of chlorpyrifos, an organophosphate pesticide on the intestinal barrier of Atlantic salmon (Salmo salar)
(Master thesis, 2021-03-20)Aquaculture is the fastest growing food producing sector worldwide. The decline in capture fisheries has led to a decrease in fish oil and fish meal production. Due to this decline, there is a need for alternative lipid ... -
Effects of cholecystokinin (CCK) on gut motility in the stomachless fish ballan wrasse (Labrus bergylta)
(Peer reviewed; Journal article, 2019-06-07)Cholecystokinin (CCK) is well-known as a key hormone that inhibits stomach emptying and stimulates midgut motility in gastric species. However, the function of CCK related to gut motility in agastric fish, especially in ... -
Effects of chronic and periodic exposures to ammonia on growth and eye health in juvenile Atlantic halibut (Hippoglossus hippoglossus)
(Master thesis, 2010-02-20)The effect of chronic and periodic peaks of un-ionised ammonia (UIA-N) exposure on growth and eye health in juvenile Atlantic halibut, Hippoglossus hippoglossus, were examined. Fish with mean initial weight 51.7 g (SD, ... -
Effects of climate change on the distribution of plant species and plant functional strategies on the Canary Islands
(Journal article; Peer reviewed, 2023)Aim Oceanic islands possess unique floras with high proportions of endemic species. Island floras are expected to be severely affected by changing climatic conditions as species on islands have limited distribution ranges ... -
Effects of cnidarian biofouling on salmon gill health and development of amoebic gill disease
(Peer reviewed; Journal article, 2018-07-06)This study examines the potential implications of biofouling management on the development of an infectious disease in Norwegian farmed salmon. The hydroid Ectopleura larynx frequently colonises cage nets at high densities ... -
Effects of complex neck therapy – kinesiotherapy and interspinal muscles massage – on tinnitus
(Journal article, 2023)Introduction: Past studies have shown connections between the somatosensory system (the neck and temporomandibular joint region) and the auditory system. It is therefore likely that tinnitus patients might benefit from ... -
Effects of cooking and freezing practices on the distribution of cadmium in different tissues of the brown crab (Cancer pagurus)
(Peer reviewed; Journal article, 2017-05)Increased cadmium concentrations in claw meat were demonstrated after cooking and freezing practices of whole brown crabs. This was investigated in crabs from two different locations along the Norwegian coast, one with ... -
Effects of copepod size on fish growth: A model based on data for North Sea sandeel
(Peer reviewed; Journal article, 2015-02-03)In productive marine off-shore ecosystems, the flow of energy from zooplankton to large predators is channeled through a few species of short-lived, highly abundant schooling planktivorous fish. There are indications that ... -
Effects of cortisol on the intestinal mucosal immune response during cohabitant challenge with IPNV in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2014-05-08)Infectious pancreatic necrosis virus (IPNV) causes high incidence of disease in salmonids during the first period after SW transfer. During this period as well as during periods of stress, cortisol levels increase and ... -
The effects of cryogenically preserved sperm on the fertilization, embryonic development and hatching success of lumpfish C. lumpus
(Journal article; Peer reviewed, 2022)Lumpfish (C. lumpus) are used as cleaner fish in the Atlantic salmon (Salmo salar) farming industry to remove parasitic sea lice. At present, wild lumpfish broodstock are used which puts strain on wild populations. By ... -
The effects of cyanobacteria on the growth, survival and behaviour of a tropical fish (Nile tilapia) and zooplankton (Daphnia lumholtzi)
(Doctoral thesis, 2009-10-30)Recent studies on the ecological effects of cyanobacteria in lakes have focused on the harmful effects of blooms to other aquatic organisms including fish and zooplankton. Much of this work has been conducted on temperate ... -
Effects of dark sector interactions on active-sterile neutrino mixing
(Master thesis, 2021-06-01)This thesis presents methods and theory for exploring new physics by using neutrinos as the portal. A thorough introduction on the state of neutrino physics in, and beyond the Standard Model framework, is presented. Anomalies ... -

Effects of diapycnal and isopycnal mixing on the ventilation of CFCs in the North Atlantic in an isopycnic coordinate OGCM
(Peer reviewed; Journal article, 2003)Simulated distributions of the chlorofluorocarbons CFC-11 and CFC-12 are used to examine the ventilation of the North Atlantic Ocean in a global version of the Miami Isopycnic Coordinate Ocean Model (MICOM). Three simulations ... -
Effects of dietary fermented sugar kelp (Saccharina latissima) on Atlantic salmon (Salmo salar) intestinal morphology and redox status
