Performance and welfare of Atlantic salmon, Salmo salar L. post-smolts in recirculating aquaculture systems: Importance of salinity and water velocity
(Journal article; Peer reviewed, 2020)Producing a larger post‐smolt in recirculating aquaculture systems (RAS) could shorten the production time in sea cages and potentially reduce mortality. Knowledge of the biological requirements of post‐smolts in ... -
Period lenght in cyclic animal populations
(Peer reviewed; Journal article, 2005)Although cyclic animal dynamics have long been a focus of scientific interest, the variable cycle lengths are poorly understood. Based on a review of the literature, we suggest that period length in animals showing multiannual ... -
Periodic changes in the zooplankton of the North Sea during the twentieth century linked to oceanic inflow
(Journal article, 2003)Oceanic inflow is estimated to contribute more than 90% of the nutrient input into the North Sea. Variability in the volume, chemical properties, biological content and source of the inflowing water is thus likely to have ... -
Periodicity of otolith check formation in the juvenile plaice Pleuronectes platessa
(Belle W.Baruch Library in Marine Science; 19, Chapter; Peer reviewed, 1995)Juvenile (Pleuronectes platessa L.) were sampled in the intertidal zone of Port Erin Bay (Isle of Man, Irish Sea) by push-net in the summers of 1990 and 1992. Check formation on the sagittal otoliths was examined to test ... -
Peripheral and central employment of acid-sensing ion channels during early bilaterian evolution
(Journal article; Peer reviewed, 2023)Nervous systems are endowed with rapid chemosensation and intercellular signaling by ligand-gated ion channels (LGICs). While a complex, bilaterally symmetrical nervous system is a major innovation of bilaterian animals, ... -
Peroxisome Proliferator-Activated Receptors (PPARs) As Tools For Studying Effects Of Contaminants On The Lipid Metabolism In Atlantic Cod (Gadus morhua)
(Master thesis, 2017-11-09)Due to its habitats near offshore oil platforms, petroleum recovery facilities, as well as coastal industries and municipal wastewater treatment plants, Atlantic cod (Gadus morhua) must cope with both legacy and emerging ... -
Persist in place or shift in space? Evaluating the adaptive capacity of species to climate change
(Journal article; Peer reviewed, 2020)Assessing the vulnerability of species to climate change serves as the basis for climate-adaptation planning and climate-smart conservation, and typically involves an evaluation of exposure, sensitivity, and adaptive ... -
Pest science in Pasteur’s Quadrant
(Journal article; Peer reviewed, 2023)More than 25 years ago, Donald Stokes argued that we must move beyond the false dichotomy of basic or applied research and suggested that when considering a program of scientific research it is important to ask whether (i) ... -
Pesticides Induce Oxidative Stress in Zebrafish Embryo
(Master thesis, 2014-06-02)Aquaculture is an industry in rapid global growth. The increased demand and therefore production of aquacultural goods is bound to drain natural marine resources if fish are to continue being fed feeds based solely on ... -
The pH sensitivity of Aqp0 channels in tetraploid and diploid teleosts
(Peer reviewed; Journal article, 2015)Water homeostasis and the structural integrity of the vertebrate lens is partially mediated by AQP0 channels. Emerging evidence indicates that external pH may be involved in channel gating. Here we show that a tetraploid ... -
Phaeobacter gallaeciensis Reduces Vibrio anguillarum in Cultures of Microalgae and Rotifers, and Prevents Vibriosis in Cod Larvae
(Peer reviewed; Journal article, 2012-08-22)Phaeobacter gallaeciensis can antagonize fish-pathogenic bacteria in vitro, and the purpose of this study was to evaluate the organism as a probiont for marine fish larvae and their feed cultures. An in vivo mechanism of ... -
Phaeoviruses Present in Cultured and Natural Kelp Species, Saccharina latissima and Laminaria hyperborea (Phaeophyceae, Laminariales), in Norway
(Journal article; Peer reviewed, 2023)Phaeoviruses (Phycodnaviridae) are large icosahedral viruses in the phylum Nucleocytoviricota with dsDNA genomes ranging from 160 to 560 kb, infecting multicellular brown algae (Phaeophyceae). The phaeoviral host range is ... -
Phagocytosis and Respiratory Burst Activity in Lumpsucker (Cyclopterus lumpus L.) Leucocytes Analysed by Flow Cytometry
(Peer reviewed; Journal article, 2012-10-24)In the present study, we have isolated leucocytes from peripheral blood, head kidney and spleen from lumpsucker (Cyclopterus lumpus L.), and performed functional studies like phagocytosis and respiratory burst, as well as ... -
Pharmacokinetic Data Show That Oxolinic Acid and Flumequine Are Absorbed and Excreted Rapidly From Plasma and Tissues of Lumpfish
(Peer reviewed; Journal article, 2019-11-12)This study examined the uptake, tissue distribution and elimination of the antibacterial agents oxolinic acid and flumequine in lumpfish (Cyclopterus lumpus L.) by use of LC-MS/MS following a single oral administration of ... -
Pharmacokinetics of florfenicol in lumpfish (Cyclopterus lumpus L.) after a single oral administration
(Peer reviewed; Journal article, 2019)Farming of lumpfish for biological removal of sea lice from farmed Atlantic salmon has expanded rapidly in Europe and Canada over the last 5–6 years and the lumpfish has become an economically important species. There are, ... -
The Phe362Tyr mutation conveying resistance to organophosphates occurs in high frequencies in salmon lice collected from wild salmon and trout
(Peer reviewed; Journal article, 2017-10-27)The parasitic salmon louse, and its resistance to chemical delousing agents, represents one of the largest challenges to the salmon aquaculture industry. We genotyped lice sampled from wild salmon and sea trout throughout ... -
Phenology and Environmental Control of Phytoplankton Blooms in the Kong Håkon VII Hav in the Southern Ocean
(Journal article; Peer reviewed, 2021)Knowing the magnitude and timing of pelagic primary production is important for ecosystem and carbon sequestration studies, in addition to providing basic understanding of phytoplankton functioning. In this study we use ... -
Phenology and Spatial Dynamics of Cacopsylla melanoneura (Homoptera:Psyllidae) in Western Norway, an Insect Vector for Apple Proliferation
(Master thesis, 2017-06-21)In the last decade, the plant disease apple proliferation has caused problems for Norwegian fruit farmers, resulting in smaller and un-tasty apples, rendering them unsellable. The disease is caused by the phytoplasma ... -
