Cold storage of eggs of Acartia tonsa Dana: effects of light, salinity and short-term temperature elevation on 48-h egg hatching success
(Master thesis, 2011)Copepods play a key role in the marine ecosystem where they form a vital trophodynamic link between primary and tertiary producers, and are the dominant prey of many marine fishes during their larval stage. Because of their ... -
Dietary effects of different live prey on growth and functional development in ballan wrasse (Labrus bergylta) larvae and juveniles
(Master thesis, 2012)Ballan wrasse (Labrus bergylta) is a new species in aquaculture, the newly initiated intensive production is a response to the increasing demands for wrasse as cleaner fish in salmon and trout farming. The dietary requirements ... -
Effects of feeding with copepod nauplii (Acartia tonsa) compared to rotifers (Brachionus ibericus, Cayman) on quality parameters in Atlantic cod (Gadus morhua) larvae
(Master thesis, 2011)Good nutritional quality is a key for a successful Atlantic cod (Gadus morhua) juvenile producer. Copepods are the natural prey for marine fish larvae, and its nutritional composition is believed to be optimal for the ... -
Effects of live feed quality on cod (Gadus morhua L.) larval hepatocyte and enterocyte development
(Master thesis, 2011)Production of high quality juveniles is still a bottleneck in the intensive culture of cod (Gadus morhua L.), and suboptimal nutrition at the larvae s early life stages is one of the decisive factors for this. The cod larva ... -
Effects of live feed quality on cod (Gadus morhua L.) larval muscle growth and development: .
(Master thesis, 2011)- -
Effects of nutrients from fish farms on culture of blue mussel (Mytilus edulis)
(Master thesis, 2011)Intensive salmonid cage culture releases nutrients and organic matter that lead eutrophication of coastal waters. Integrated multi-trophic aquaculture (IMTA) is receiving great attention as a means of reducing organic/inorganic ... -
Seasonal Variations in Biofouling and Plankton Community Connected to a Large Scale Salmon Farm.
(Master thesis, 2011)Biofouling is the one of the main problems in marine finfish aquaculture. Biofouling occludes the nets and incurs major costs to fish farmers in the form of copper containing anti fouling paints used on the net surfaces, ... -
Skeletal muscle growth dynamics and the influence of first-feeding diet in Atlantic cod larvae (Gadus morhua L.)
(Journal article; Peer reviewed, 2016)Dynamics between hypertrophy (increase in cell size) and hyperplasia (increase in cell numbers) of white and red muscle in relation to body size [standard length (SL)], and the influence of the first-feeding diets on muscle ... -
Sori disinfection in cultivation of Saccharina latissima: Evaluation of chemical treatments against diatom contamination
(Master thesis, 2012)Diatom contamination is a problem in the early cultivation stages of Saccharina latissima. Macro- and microalgae compete for the same abiotic resources, and diatoms may overgrow and eliminate seedlings of S. latissima if ... -
The effect of different live feed on the early growth and development of ballan wrasse (Labrus bergylta Ascanius, 1767) larvae and its organs
(Master thesis, 2012)Salmon lice (Lepeophtheirus salmonis) have been an increasing problem for the Norwegian aquaculture industry in recent years, and several chemicals have been used by the industry to get rid of the louse. However, resistance ... -
The effect of different live prey types on growth and muscle development, in ballan wrasse (Labrus bergylta, Ascanius 1767) larvae
(Master thesis, 2012)Sea lice have been causing problems in Norwegian salmon farming industry for decades; increasing mortality and reducing the welfare of farmed and wild fish. Various chemical agents have been used to combat sea lice, but ... -
The effect of incubation temperature on embryonic development and muscle growth in yolk-sac larvae of the European eel (Anguilla anguilla L., 1758)
(Master thesis, 2012)Reproduction of European eel (Anguilla anguilla) in aquaculture systems has become a focus research area due to severe decline of natural stocks, and increasing interest to breed eels for a self-sustained aquaculture. ...
