(The University of Bergen, 2018-05-30)Taurine has been reported as a conditionally essential nutrient for several marine fish. Ballan wrasse (Labrus bergylta) has become an important species for the Atlantic salmon (Salmo salar) industry in Norway. Rotifers ...Master thesis -
Cadmium in Brown Crab Cancer pagurus in Norwegian Waters
(The University of Bergen, 2018-05-23)The Brown crab Cancer pagurus is appreciated as seafood and its fishery is of importance in several European countries. However, findings of high levels of cadmium have increased concern about food safety, and spatial ...Doctoral thesis -
High-value fatty acids from microalgae. Bioprospecting and outdoor cultivation at northern latitudes
(The University of Bergen, 2018-05-11)Achieving a sustainable and cost-efficient production is imperative to establish microalgae as a new feedstock for aquaculture, where they can potentially replace the use of fish oil from wild catch as a source for the ...Doctoral thesis -
Mucosal responses in post-smolt Atlantic salmon (S. salar) following salmon lice (L. salmonis) infections
(The University of Bergen, 2018-05-04)The aquaculture sector is becoming increasingly important both for food production and economic reasons. The main problem today in Norwegian aquaculture is the copepod ectoparasite Leopeophtheirus salmonis which limits ...Master thesis -
Population structure and dynamics of Atlantic herring. A case study of herring inhabiting marginal habitats in Landvikvannet and its vicinity
(The University of Bergen, 2018-05-04)Knowledge about the structure and dynamics of marine fish populations is essential for their conservation and management to maintain biodiversity and population complexity. Atlantic herring (Clupea harengus) is one of ...Doctoral thesis -
The use of photo and video as surveying tools on sessile organisms in shallow soft-bottom habitats - Photoframe and videosleigh method
(The University of Bergen, 2018-04-18)The Institute of Marine Research (IMR) wants to start a systematic survey of shallow, soft-bottom habitats. The IMR wants to implement two new methods using photo and video, the photoframe and the videosleigh method. Where ...Master thesis -
Enhancing EPA Content in an Arctic Diatom: A Factorial Design Study to Evaluate Interactive Effects of Growth Factors
(Frontiers, 2018-04-17)Microalgae with a high content of the omega-3 polyunsaturated fatty acids (PUFAs), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) are of great demand for microalgae-based technologies. An Arctic strain of the ...Journal article -
Cadmium in the shore crab Carcinus maenas along the Norwegian coast: geographical and seasonal variation and correlation to physiological parameters
(Springer, 2018-04)Previously, high concentrations of cadmium have been found in the hepatopancreas of the edible or brown crab (Cancer pagurus) sampled from positions north of about 67° N, compared to regions further south along the Norwegian ...Journal article -
Genetic connectivity from the Arctic to the Antarctic: Sclerolinum contortum and Nicomache lokii (Annelida) are both widespread in reducing environments
(Nature Publishing Group, 2018-03-19)The paradigm of large geographic ranges in the deep sea has been challenged by genetic studies, which often reveal putatively widespread species to be several taxa with more restricted ranges. Recently, a phylogeographic ...Journal article -
Evolutionary history, connectivity and habitat-use of annelids from deep-sea chemosynthesis-based ecosystems, with an emphasis on the Arctic mid-Ocean Ridge and the Nordic Seas
(The University of Bergen, 2018-03-16)The enigmatic fauna of chemosynthesis-based ecosystems (CBEs), i.e. hydrothermal vents, cold seeps and organic falls, has been the subject of intensive research over the last decades. However, there are still many aspects ...Doctoral thesis -
Comparing EPA production and fatty acid profiles of three Phaeodactylum tricornutum strains under western Norwegian climate conditions
(Elsevier, 2018-03)Microalgae could provide a sustainable alternative to fish oil as a source for the omega-3 polyunsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). However, growing microalgae on a large-scale ...Journal article -
The antecedents and consequences of students´ autonomous motivation. The relation between need-support, motivation, and academic achievement
(The University of Bergen, 2018-02-16)Higher education has traditionally rested on teacher-centred education. Recently, there has been a shift towards learner-centred education. Innovative teaching tools, active teaching methods, and teachers that encourages ...Doctoral thesis -
Genetic factors have a major effect on growth, number of vertebrae and otolith shape in Atlantic herring (Clupea harengus)
(PLOS, 2018-01-11)Atlantic herring, Clupea harengus, have complex population structures. Mixing of populations is known, but the extent of connectivity is still unclear. Phenotypic plasticity results in divergent phenotypes in response to ...Journal article -
Characterization of three salmon louse (Lepeophtheirus salmonis) genes with fibronectin II domains expressed by tegumental type 1 glands
(Elsevier, 2018-01)The salmon louse, Lepeophtheirus salmonis (Copepoda: Caligidae), is currently the most significant pathogen affecting the salmon farming industry in the Northern Hemisphere. Exocrine glands of blood-feeding parasites are ...Journal article -
Driving forces in the distributions of the three most common deep-water coral species in Norway: Lophelia pertusa, Paragorgia arborea, and Primnoa resedaeformis
(The University of Bergen, 2017-12-20)This thesis explores a set of environmental variables may be used to predict the spatial distribution of the three most common cold-water coral (CWC) species in Norway: Lophelia pertusa, Paragorgia arborea, and Primnoa ...Master thesis -
Estimating genetic diversity in a domesticated population of Norwegian Atlantic salmon (Salmo salar) using genomic data
