Optimising cell wall disruption of microalgae biomass for release of nutrients and bioactive compounds for aquafeed and food applications
(Master thesis, 2019)Microalgae are photosynthetic organisms and primary producers of essential nutrients in the aquatic food chain. Although currently less exploited, microalgae culture can provide nutrients to cover the increasing demand for ... -
A deeper look; Does Heincke´s law apply to Atlantic cod (Gadus morhua) in the Barents Sea and what is the effect of eye size on prey encounter rate?
(Master thesis, 2019-05-28)The Atlantic cod (Gadus morhua) is arguably one of the most valuable fish we have, and the Barents Sea stock, Northeast Arctic cod (NEAC), is the largest stock in the world. Despite the long history of fishing and the ... -
Applying fisheries data from the Norwegian reference fleet to study the demersal biodiversity and fisheries dynamics in two coastal areas
(Master thesis, 2019-06-05)It is well established that biodiversity varies throughout the year, over many years and between areas, and that biodiversity plays an important role in the overall health and resilience of an ecosystem. As fisheries ... -
Juvenile mackerel (Scomber scombrus) along the Norwegian Coast: distribution, condition and feeding ecology
(Master thesis, 2019-06-14)There has been a substantial increase in the stock size of North East Atlantic (NEA) mackerel (Scomber scombrus) during the last decade (2006-2016), coinciding with record high recruitment. This situation has resulted in ... -
Distribution and feeding ecology of fin (Balaenoptera physalus) and humpback whales (Megaptera novaeangliae) in the Norwegian Sea during the summers of 2013 to 2018
(Master thesis, 2019-06-14)This study aims at describing the current (2013 to 2018) summer distribution and feeding ecology of fin whales (Balaenoptera physalus) and humpback whales (Megaptera novaeangliae) in the Norwegian Sea. These waters function ... -
Species composition, distribution and ecology of the demersal fish community along the Norwegian coast north of Stad under varying environmental conditions
(Master thesis, 2019-06-14)In the last decades, temperatures of the Atlantic current that enters the Norwegian Coastal Current (NCC) has been above the yearly average, with 2007 as the warmest registration on record (Skagseth 2012). The climatic ... -

Seasonal zooplankton dynamics in Svalbard coastal waters: The shifting dominance of mero- and holoplankton and timing of reproduction in three species of Copepoda
(Master thesis, 2019-06-15)Monthly sampling was conducted in the ice-free Adventfjorden in West Spitsbergen, Svalbard, from March to November 2018 to assess the seasonal development in the Arctic zooplankton community and to investigate the seasonally ... -
The Infection Cycle of Marteilia pararefringens sp. nov. in the blue mussel, Mytilus edulis L.
(Master thesis, 2019-06-18)In 2016 the first case of marteiliosis in Norway was reported by the Institute of Marine Research. The discovery occurred in Agapollen, Bømlo, a previously active oyster pond. The parasite Marteilia pararefringens sp. nov. ... -
Community composition, population structure and phylogeny of coastal sympagic meiofauna in eastern Svalbard
(Master thesis, 2019-06-19)Coastal sea ice communities constitute a highly vulnerable yet little investigated part of the Arctic ecosystem. A better understanding of the Arctic sea ice ecosystem will aid in more accurate predictions of the ecological ... -
Co-infection of Atlantic salmon (Salmo salar) by Lepeophtheirus salmonis and Moritella viscosa
(Master thesis, 2019-06-20)A co-infection is defined as an infection with two or more different pathogens, where the pathogens can either have a synergistic or antagonistic effect or alternatively not affect each other at all. Lepeophtheirus salmonis ... -
Male mate choice and selectivity in relation to female body size, in the seed beetle Callosobruchus maculatus
(Master thesis, 2019-06-21)Selectivity in mate choice and mating behaviour is a central element of sexual selection, and an important component of evolution in a number of species across the animal kingdom. Mate choice relates to how individuals ... -
Can catch data from small meshed gears in shallow waters be used to estimate recruitment indices of Norwegian coastal cod, Northeast Arctic saithe and pollack along the Norwegian coast?
(Master thesis, 2019-06-21)Shallow waters (<30 meters) are important nursery areas for coastal cod, saithe and pollack, before they recruit to their respective fisheries at an age around 3 years old. Still, no study provides information on fish ... -
