Assessment of growth performance and liver lipid accumulation in Atlantic salmon (Salmo salar) fed an insect-based diet
(Master thesis, 2018-06-26)Increase in price and reduced availability of fish meal (FM) has caused the aquaculture industry to look at alternative sources for nutrients for feed production. Vegetable protein sources can replace a substantial part ... -
Effect of tryptophan enriched diets on aggression in hierarchical groups of juvenile Atlantic salmon (Salmo salar)
(Master thesis, 2010-07-01)Aggression in fish hierarchies often leads to one dominant individual monopolizing resources (food/shelter), thus increasing their fitness. Meanwhile individuals in subordinate ranks, endure high stressful conditions, which ... -
Enrichment of rotifers (Brachionus plicatilis) with taurine-filled liposomes and taurine-uptake in Ballan wrasse (Labrus bergylta) larvae
(Master thesis, 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 ... -
The impact of micro-mineral sources and their availability on hepatic lipid metabolism in Atlantic salmon (Salmo salar)
(Master thesis, 2018-06-27)The increased use of plant-based ingredients in aquafeeds for Atlantic salmon has led to an increase in phytate, an antinutrient binding micro minerals and reducing their bioavailability. It has been suggested that the ... -
In vitro bacterial and viral response in head kidney leukocytes of Atlantic salmon (Salmo salar) fed dietary insects meal.
(Master thesis, 2018-06-07)With the fast growth of today’s aquaculture industry, the demand for aqua-feeds is expanding dramatically. Insects, which are part of the natural diet of salmonids, could represent a sustainable ingredient for aquaculture ... -
Nutritional and environmental impacts on skin and mucus condition in Atlantic salmon (Salmo salar L.)
(Doctoral thesis, 2015-10-09)The skin and associated mucus layer of Atlantic salmon constitutes its first line of defence against the aqueous environment. Through intensive farming, a range of stressors including both mechanical and environmental ... -
Solving bottlenecks in triploid Atlantic salmon production. Temperature, hypoxia and dietary effects on performance, cataracts and metabolism
(Doctoral thesis, 2016-12-14)In salmon aquaculture, fish occasionally escape from net pens. These domesticated salmon are genetically maladapted for living in natural environments however they still manage to interbreed with wild fish, resulting in ... -
Spawning, settlement and growth of Ciona intestinalis in Øygarden, Hardangerfjorden and Kvitsøy
(Master thesis, 2015-04-24)Due to the increasing aquaculture industry, new resources for feed should be assessed. A high protein content in Ciona intestinalis have increased the interest to farm C. intestinalis, and use as a feed resource. In addition, ...
