Histological investigation of gill health responses to recirculating aquaculture system (RAS) water quality in apparently healthy Atlantic salmon (Salmo salar)
(Master thesis, 2020-08-04)Recirculating aquaculture system (RAS) technology has become more widespread in Atlantic salmon farming, and the need for knowledge about operating such a system has been highlighted in recent years. Gill pathology has ... -
Infection dynamics of marine Eubothrium sp. (Cestoda) in farmed Atlantic salmon
(Master thesis, 2019-06-21)Infections with marine tapeworms have been reported as an increasing problem in aquaculture of Atlantic salmon (Salmo salar L.) in Norway over the last few years. These are caused by the cestode Eubothrium sp. Little is ... -
Paramoeba perurans and AGD in Norwegian aquaculture: effect of freshwater treatment against AGD on gill health in commercial production of Atlantic salmon (Salmo salar L.) and experimental testing of virulence of Paramoeba perurans
(Master thesis, 2021-06-11)Gill diseases are a major and increasing challenge with respect to fish health and welfare during the marine stage in Atlantic salmon farming. The causative agents for gill diseases are complex, and several pathogens are ... -
Skin development in Atlantic salmon (Salmo salar) post-smolts reared in freshwater or low strength seawater and effect on susceptibility to Tenacibaculum finnmarkense
(Master thesis, 2020-06-24)Ulcer development caused by bacterial infections in the sea is a large problem in the Norwegian salmon farming industry, leading to increased mortalities, reduced fish welfare, down-classification at harvest, and increased ... -
Towards a challenge model for the tapeworm Eubothrium crassum - incubation of cestode eggs and maintenance of a marine intermediate host, Acartia tonsa
(Master thesis, 2022-06-01)Bendelormen Eubothrium crassum Bloch (Cestoda: Bothriocephalidea) er en parasitt som forekommer hovedsakelig hos laksefisker i både ferskvann og sjøvann. Den er et økende problem i norsk oppdrettslaks (Salmo salar Linnaeus) ... -
Trichlorfon, a salmon lice pesticide, and the effect on metabolism and inflammation in Atlantic salmon (Salmo salar, L.)
(Master thesis, 2020-06-26)Since the beginning of the salmon farming industry in Norway, the substantial fish health and welfare and economic costs caused by the parasitic salmon lice (Lepeophtheirus salmonis) has increased in tandem with the expanding ... -
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 ... -
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 ...
