USING LIGAND-ACTIVATED RECEPTORS FROM ATLANIC COD (Gadus morhua) AND ZEBRAFISH (Danio rerio) TO ASSESS BIOLOGICAL EFFECTS OF PHARMACEUTICALS IN WASTEWATER IN BERGEN, NORWAY
(Master thesis, 2021-09-01)Pharmaceuticals and personal care products are continuously released into the marine environment through wastewater. Understanding the possible biological implications of pharmaceuticals specifically may be particularly ... -
Validation of Atlantic salmon (Salmo salar) weight estimation by stereo camera, and morphometric analysis for assessment of growth performance and maturation status
(Master thesis, 2021-04-26)Stereo image analysis of free-swimming farmed Atlantic salmon is today used for purposes such as individual size estimation and sea lice counting. This technology may in the future be used to score welfare and life history ... -
Valorisation of waste streams from recirculating aquaculture systems by photoautotrophic microalgae
(Master thesis, 2022-09-11)The low water consumption in Recirculating Aquaculture Systems (RAS) can result in relatively high concentrations of polluting nutrients in effluent waste streams (WSs) compared to traditional Flow-through systems (FTS). ... -
Vekstmønsteret til havsil (Ammodytes marinus, Raitt 1934) og variasjoner mellom årsklasser og områder i Nordsjøen.
(Master thesis, 2019-12-19)På sandbanker i Nordsjøen lever en unik, liten og sølvblank fisk som er viktig for produksjon av fiskemel og fiskeolje og som spiller en avgjørende rolle i sitt økosystem. Rekrutteringen av havsilbestanden varierer fra år ... -
Vgll3 knockout as a means to delay male maturity during large smolt production of Atlantic salmon (Salmo salar L.)
(Master thesis, 2023-12-01)With a 100 billion NOK export value, Atlantic salmon (Salmo salar L.) has become one of the most important export products for Norway. A highly intensified production in recirculating aquaculture systems (RAS) has pushed ... -

Welfare and efficiency of warm and cold waterfall (low pressure flushing) as delousing treatment of Atlantic salmon (Salmo salar)
(Master thesis, 2021-06-01)Salmonid aquaculture plays an important role in increasing global fish production and the biggest factor constraining its further growth and development in Norway is salmon lice (Lepeophtheirus salmonis). Previous projects ... -
Why do birds lay eggs that fail to hatch?
(Master thesis, 2019-06-22)In birds, an average of 10-15% of eggs reportedly fail to hatch and remain in the nest after completed incubation. This is due to either fertilization failure or embryo death. Hatchability (the proportion of eggs hatching) ...
