Denne oppgaven behandler norske børsnoterte oppdrettsselskapers tilpasning til International Financial Reporting Standards (IFRS) med hovedfokus på IAS 41 Agriculture. I første del av oppgaven gjennomgås regnskapsregulering for børsnoterte selskaper etter innføring av IFRS, herunder viktige forhold i norsk regnskapslovgivning, IFRS og IAS 41. I henhold til IAS 41 skal all levende biomasse verdsettes ...

In this study, five isolated Arctic marine bacteria of the genus Arthrobacter were cultivated under different temperatures and growth media. Employing the “One Strain-Many Compounds” (OSMAC) approach, in an attempt to produce novel and interesting compounds with potential bioactivity by triggering different metabolic pathways. The motivation for this thesis was to discover new types of arthrobacilins ...

Isolation of bioactive products from the marine environment is considered a very promising approach to identify new compounds that can be used for further drug development. In this work we have isolated three new compounds from the purpuroine family by mass-guided preparative HPLC; purpuroine K-M. These compounds where screened for antibacterial- and antifungal activity, antibiofilm formation and ...

This study presents a data-driven modelling approach to identify important factors influencing the growth- and mortality rate for farmed salmon in northern Norway. Furthermore, a model is trained to determine the best fish farming sites and identify optimal areas with the best geographical conditions. Aquaculture site production and location data from 323 salmon farming sites (all licensed aquaculture ...

Doctoral candidates are facing a diverse employment landscape that shifted significantly in the last decades, with less than 30 % of doctoral graduates working in academia or in research and development related jobs. In addition to becoming more inter-sectoral, working environments are becoming increasingly inter-national and inter-disciplinary. This development can make the employment requirements ...

The management of the Norwegian Northeast Atlantic cod fishery has in many ways been a success story; quotas have been high (but now declining), profitability has been higher than most other industries and there is great interest among young recruits to enter the fishery. However, over the last decade illegal fishing of allocated quotas and black-market transactions throughout the value chain ...

An image is what we have in our head and what we make up in an allegory, a name, a metaphor, a text, a map or in a drawing. None of these should be confused with the thing that is being imagined. They are not the real thing, just our imaginations of it. Still, we could not do without them, for instance when governing small-scale fisheries. They make us understand what we are up to and the track we ...

Oppdrett av laks (Salmo salar L.) har utviklet seg til å bli en stor og viktig næring i Norge. Videre vekst i næringen er i dag først og fremst begrenset av problematikken rundt lakselus (Lepeophtheirus salmonis K.), og det er et økt behov for nye ikke-medikamentelle metoder for avlusing av laks i sjø. Bruken av oppdrettet rognkjeks (Cyclopterus lumpus L.) som lusespiser, er en metodene som har vist ...

The discovery of CRISPR/Cas9 as a gene editing tool has revolutionized the field of molecular biology due to its huge potential for innovative applications. However, the biosafety concerns on CRISPR/Cas9-mediated gene editing like off-target mutations, triggering of cell death, and induction of cellular stress need to be elucidated. This thesis aims to investigate the impacts of electroporation ...

Since the late 1980s, Norwegian fishers have been subjected to a cohesive regulatory regime aimed at sustainable resource management. Despite high occupational injury rates and exposure to several factors that may influence health negatively, regulation of occupational health and safety (OHS) came late in fishing compared with other industries. Fisheries management and safety management are not ...
