Analyses of bacteriophages to Yersinia ruckeri and the salmon (Salmo salar L.) antibody response to the bacteriophages.
(Master thesis, 2017-06-30)New technologies for producing Atlantic salmon like the recirculation aquaculture systems (RAS) have gained popularity, and has overthrown the traditional flow through systems used in the freshwater stages of the Atlantic ... -
Eksperimentell eksponering av laksefiskyngel for salmonid alphavirus (SAV3) – Sammenligning av mottakelighet og konsekvens hos brunørret (Salmo trutta L.) og atlantisk laks (Salmo salar L.)
(Master thesis, 2018-12)Salmonid alfavirus (SAV) forårsaker pankreassyke (PD) hos laksefisk i oppdrett. PD er utbredt i Norge og var den mest rapporterte virussykdommen i 2017. Det er en bekymring at rømt oppdrettsfisk som er infisert med viruset ... -
Feltoppfølging av rognkjeks vaksinert mot Aeromonas salmonicida A-lagstype V og VI
(Master thesis, 2017-06-16)Efficient sea-lice control is still one of the most important challenges for the salmon farming industry, and use of cleaner fish as biological delousing has increased considerably in recent years. Mortality of lumpsucker ... -
Francisella philomiragia subsp. noatunensis i torskeleukocytter
(Master thesis, 2009-06-22)Det er velkjent at en rekke intracellulære bakterier, inkludert flere arter innen slekten Francisella, har evne til å oppholde seg og formere seg i immuncellene. I dette studiet ble det utført smitteforsøk in vitro der det ... -
Functional investigations of the Ecdysone Receptor and production of ecdysone in the salmon louse (Lepeophtheirus salmonis)
(Doctoral thesis, 2016-05-24)The salmon louse Lepeophtheirus salmonis is a marine ectoparasitic copepod naturally infecting salmonid fishes in the Northern hemisphere. At present, salmon louse infections are the most severe disease problem in the ... -
Histochemical characterization of AGD lesions in ballan wrasse (Labrus bergylta)
(Master thesis, 2017-07-07)With the increasing problem of sea lice (Lepeoptheirus salmonis) in production of Atlantic salmon (Salmo salar), the use of biological and non-drug treatments, such as cleaner fish, like ballan wrasse (Labrus bergylta) and ... -
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 ... -
Quorum sensing and biofilm formation potential in Norwegian Tenacibaculum dicentrarchi isolates
(Master thesis, 2018-11-20)Fish farming has become one of the most important industries in Norway. To handle further growth, both in sea- and land-based facilities, challenges should be dealt with in a sustainable manner. Among these challenges are ... -
Respiratory burst assay for leukocytter fra Atlantisk laks (Salmo salar L.) og Atlantisk torsk (Gadus morhua L.)
(Master thesis, 2009-06-22)Fagocytose er en viktig funksjon i det uspesifikke immunforsvaret hos fisk, og medvirker til at leukocytter kan drepe infiserende patogener. Leukocytters evne til å ta opp, drepe og bryte ned fagocytterte patogener, er ... -
Survival of Salmonid Alphavirus in seawater under different physical conditions
(Master thesis, 2014-08-06)Pancreas disease (PD) is an infectious disease caused by Salmonid alphavirus (SAV), which infects Atlantic salmon, Salmo salar L., and rainbow trout, Oncorhynchus mykiss (Walbaum). PD causes substantial economical losses ... -
