Cold storage of eggs of Acartia tonsa Dana: effects of light, salinity and short-term temperature elevation on 48-h egg hatching success
Hagemann, Andreas (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 ... -
Effects of copepod density and water exchange on the egg production of Acartia tonsa Dana (Copepoda: Calanoida) feeding on Rhodomonas baltica
Salveson, Erik (Master thesis, 2013)In this study, the objective was to investigate the effect of different copepod densities and the water exchange rate day-1 on the egg production of Acartia tonsa feeding on Rhodomonas baltica. It was a main task to find ... -
Effects on growth, survival and bone development from start feeding lumpsucker (Cyclopterus lumpus) larvae with Artemia, copepods and fomulated feed
Hanssen, Julie Terese (Master thesis, 2018)Salmon lice (Lepeoptherius solmonis) is a major health problem in salmon (Salmo salar) production. Reduced lice sensitivity towards several of the chemical treatments have increased the interest in cleaner fish used to ... -
Effekten av to synlig lys modaliteter og røntgen på klekkesuksessen hos Acartia tonsa-egg
Vorren, Sigbjørn Hjetland (Master thesis, 2014)For å få en stabil og forutsigbar klekking av Acartia tonsa er kunnskapom miljøparametere som påvirker klekkingen essensielt. Målet med denneoppgaven var å undersøke hvilken virkning ulike kvaliteter av synlig lysinkludert ... -
Growth and stress factors in ballan wrasse (Labrus bergylta) larval development
Piccinetti, Chiara Carla; Grasso, Lorenzo; Maradonna, Francesca; Radaelli, Giuseppe; Ballarin, Cristina; Chemello, Giulia; Evjemo, Jan Ove; Carnevali, Oliana; Olivotto, Ike (Journal article; Peer reviewed, 2017)Ballan wrasse (Labrus bergylta) is a specialized cleaner fish used in salmon farms as a biological treatment against sea lice. Its commercial rearing is at present mostly experimental. A number of key aspects, including ... -
Kjemisk desinfisering av egg til copepoden Acartia tonsa
Singsaas, Katrine (Master thesis, 2014)Copepoder har god næringsverdi og er en viktig fôrkilde for marine fiskelarver i havet. Vedoppdrett av mange marine fiskearter er copepoder et godt alternativ til de tradisjonellefôrorganismene; Artemia og rotatorier. ... -
Production and nutritional adaptation of the brine shrimpArtemia sp. as live food organism for larvae of marine cold water fish species
Evjemo, Jan Ove (Doctoral thesis, 2001)High nutritional value of Artemia sp. refers to high content of highly unsaturated fatty acids (n-3 HUFA) and in particular the content of DHA. In the enrichment experiments presented in this thesis new diets and one new ... -
Temporal Development of the Gut Microbiota in European Lobster (Homarus gammarus) Juveniles Exposed to Two Different Water Treatment Systems
Kristensen, Elisabeth (Master thesis, 2015)Aquaculture today exploits only a limited number of species for production and there is a need to utilize novel species. One such species that could contribute to meeting the demands of the market is the European lobster. ... -
The effect of different live feeds and water qualities on growth, survival, ossification and skeletal anomalies of ballan wrasse (Labrus bergylta) larvae
Høyland, Oda Skognes (Master thesis, 2015)Salmon lice (Lepeophtheirus salmonis) infections is one of the major problems in Atlantic salmon (Salmo salar) aquaculture. This has led to an increasing interest in the cultivation of ballan wrasse (Labrus bergylta), for ... -
UV treatment in RAS influences the rearing water microbiota and reduces the survival of European lobster larvae (Homarus gammarus)
Attramadal, Kari J.K.; Øien, John Vegard; Kristensen, Elisabeth; Evjemo, Jan Ove; Kjørsvik, Elin; Vadstein, Olav; Bakke, Ingrid (Peer reviewed; Journal article, 2021)The rearing environment is important for a stable production of good quality lobster juveniles. By providing an environment excluding pathogens and dominated by mutualistic bacteria, the probability of developing healthy ...
