A case study of biofilter activation and microbial nitrification in a marine recirculation aquaculture system for rearing Atlantic salmon (Salmo salar L.)

Roalkvam, Irene; Drønen, Karine; Dahle, Håkon; Wergeland, Heidrun Inger (Peer reviewed; Journal article, 2020-09)

Marine recirculation aquaculture system (RAS) is a prominent technology within fish farming. However, the nitrifying bacteria in the biofilter have low growth rates, which can make the biofilter activation a long and ...
MICROBIAL COLONIZATION AND COMMUNITY SHIFTS IN A MARINE POST-SMOLT RAS DURING THE FIRST YEAR OF OPERATION AS ANALYZED BY DEEP SEQUENCING

Drønen, Karine (Master thesis, 2019-12-13)

Resirkulering akvakultur systemer (RAS) teknologi for ferskvannsproduksjon av smolt ble for første gang brukt med marint vann for post-smolt påvekst, dvs. påvekst 100-500 gram i tre måneder. Mikrobiell dypsekvensering av ...
Microbial Communities in a Flow-Through Fish Farm for Lumpfish (Cyclopterus lumpus L.) During Healthy Rearing Conditions

Roalkvam, Irene; Drønen, Karine; Dahle, Håkon; Wergeland, Heidrun Inger (Peer reviewed; Journal article, 2019-07-12)

Lumpfish can efficiently remove sea lice from Atlantic salmon in net-pens, and production of lumpfish in closed fish farms is a new, fast developing industry in Norway. However, periodic outbreaks of bacterial diseases in ...
