Effect of viral RNA mimics and ISA virus infection on expression of key genes of the Atlantic salmon interferon system
(Doctoral thesis; Doktorgradsavhandling, 2008)
We have studied the innate immune responses of Atlantic salmon and how this responds to stimulation and infection by the aquatic orthomyxovirus Infectious salmon anemia virus (ISAV). This work has focused on the Type I interferon (IFN) system which is critically important in the vertebrate immune response against viral infections. As a part of this work we have studied the Atlantic salmon IFN ...
Food safety of salt-cured cod products : effects of salt-curing, rehydration and thermal treatmenton survival, growth and invasiveness of Listeria spp.
(Doctoral thesis; Doktorgradsavhandling, 2010-11-26)
Salt-cured and dried salt-cured (klipfish) cod (Gadus morhua L.) are highly appreciated. Salt fish and klipfish are mainly prepared by rehydration to lower the level of salt. The rehydrated cod can be used in several dishes and consumption of these products has been considered safe due to the high level of salt. The overall aim of the thesis was to study the food safety of salt-cured fish products ...

Post mortem proteolytic degradation of myosin heavy chain in skeletal muscle of Atlantic cod
(Doctoral thesis; Doktorgradsavhandling, 2011-01-28)
One of the most important parameters of quality regarding meat both from mammals and fish is texture. The post mortem degradation of muscle and connective tissue proteins during tenderization of meat from warm-blooded animals is unwanted in fish due to a loss of product quality. Soft fillet and gaping are common problems both in wild and farmed cod and have huge impact on the quality and the consumers’ ...
Scavenging amphipods in the high Arctic : Studies of benthic and sympagic amphipods in the genera Onisimus and Anonyx
(Doctoral thesis; Doktorgradsavhandling, 2011-05-02)
The main objective of this study was to increase our knowledge about the ecology of scavenging amphipods, particularly amphipods within the genera Onisimus and Anonyx. Specifically, the emphasis was to increase the knowledge of ice-associated (sympagic) Onisimus-species, but as these species are rather inaccessible, an approach using benthic congeners as proxies was chosen. By studying the shallow-water ...
Boundary construction in mandated science : the case of ICES' advice on fisheries management
(Doctoral thesis; Doktorgradsavhandling, 2008-11-21)
What is the relationship between science and politics? What should it be? How are their respective roles conceived and acted out in practice? Should science and politics be clearly separated? How? Are there cases in which they can be usefully mixed? What cases are those, and are there some ways of mixing that are better than others? This project explores such questions by examining relationships ...
Information in financial markets : how private information affects prices, how it can be revealed and how it may be used
(Doctoral thesis; Doktorgradsavhandling, 2008-06-06)
The literature on financial markets is vast and it is probably safe to say that all tools in the economists’ tool case have been applied to this field. In this dissertation I will present three papers that are very diverse in their approach to the subject of finance, but have an important common theme; asymmetric information and efficiency in financial markets.
Consideration set size and choice in fish consumption : the influence of attitude, knowledge, convenience, and category presentation
(Doctoral thesis; Doktorgradsavhandling, 2010-06-11)
<i>Purpose</i> – Three main objectives are defined in this thesis: 1) To determine the extent to which the nature of a consideration set affects consumer choice; 2) To investigate how consumer attitudes, knowledge, and convenience motivations affect the formation of a consideration set; and 3) To investigate how category presentation moderates the relationship between convenience motivations and ...
Antimicrobial natural products from Arctic and sub-Arcticmarine invertebrates
(Doctoral thesis; Doktorgradsavhandling, 2010-09-17)
Infectious diseases are a leading cause of death world-wide and there is a growing need for new anti-infective agents to combat multi-resistant strains of bacteria and fungi. Marine natural products are promising sources of novel antimicrobial compounds. In the present thesis, an investigation into the antimicrobial metabolites of Arctic and sub-Arctic marine invertebrate species is presented. ...
The potential for cooperation in shared fisheries : theory and application to Vietnam's fisheries strategy in the South China Sea
(Doctoral thesis; Doktorgradsavhandling, 2009-06-05)
Since the end of the 20th century, many shared fish stocks throughout the world have been found in extreme danger of collapse. There are many calls for cooperation in utilizing and conserving the shared fish resources including the 1982 UN Convention on the Law of the Sea and the 1995 UN Fish Stock Agreement. This study provides an important rationale for cooperation in utilizing a shared fish stock ...
