Biofilms remember: Osmotic stress priming as a microbial management strategy for improving salinity acclimation in nitrifying biofilms
Navada, Sharada; Vadstein, Olav; Gaumet, Frederic; Tveten, Ann-Kristin; Spanu, Claudia; Mikkelsen, Øyvind; Kolarevic, Jelena (Peer reviewed; Journal article, 2020)With increasing freshwater scarcity and greater use of seawater,fluctuating salinities are becomingcommon in water treatment systems. This can be challenging for salinity-sensitive processes like nitri-fication, especially ... -
Characterizing changes of dissolved organic matter composition with the use of distinct feeds in recirculating aquaculture systems via high-resolution mass spectrometry
Aguilar-Alarcón, Patricia; Gonzalez, Susana V.; Simonsen, Mads; Borrero-Santiago, Ana R.; Sanchís, Josep; Meriac, Andre; Kolarevic, Jelena; Asimakopoulos, Alexandros G.; Mikkelsen, Øyvind (Peer reviewed; Journal article, 2020)Recirculating aquaculture systems (RAS) are a new alternative to traditional aquaculture approaches, allowing full control over the fish production conditions, while reducing the water demand. The reduction of water exchange ... -

Noble, Christopher; Iversen, Martin Haugmo; Lein, Ingrid; Kolarevic, Jelena; Johansen, Lill-Heidi; Burgerhout, Erik; Puvanendran, Velmurugu; Kousoulaki, Katerina; Aas, Grete Hansen; Stene, Anne; Espmark, Åsa Maria Olofsdotter (Research report, 2019) -
RENSVEL OWI FACT SHEET SERIES: An introduction to Operational and Laboratory-based Welfare Indicators for lumpfish (Cyclopterus lumpus L.)
Noble, Christopher; Iversen, Martin Haugmo; Lein, Ingrid; Kolarevic, Jelena; Johansen, Lill-Heidi; Berge, Gerd Marit; Burgerhout, Erik; Puvanendran, Velmurugu; Mortensen, Atle; Stene, Anne; Espmark, Åsa Maria Olofsdotter (Research report, 2019)Fish welfare, defined by Stien et al., (2013) as the “quality of life as perceived by the animals themselves” requires various tools to assess and evaluate it (see e.g. Noble et al., 2018). These tools are termed Welfare ... -
Salinity acclimation strategies for nitrifying bioreactors in recirculating aquaculture systems
Navada, Sharada (Doctoral theses at NTNU;2021:33, Doctoral thesis, 2021)The demand for seafood is rising like never before, and unsustainable fishing has depleted the oceans. Recirculating aquaculture systems (RAS) can present a sustainable solution by producing seafood in land-based systems ... -
A salty start: Brackish water start-up as a microbial management strategy for nitrifying bioreactors with variable salinity
Navada, Sharada; Sebastianpillai, Marianna; Kolarevic, Jelena; Fossmark, Ragnhild Olsen; Tveten, Ann-Kristin; Gaumet, Frederic; Mikkelsen, Øyvind; Vadstein, Olav (Peer reviewed; Journal article, 2020)Nitrifying biofilms developed in brackish water are reported to be more robust to salinity changes than freshwater biofilms. This makes them a promising strategy for water treatment systems with variable salinity, such as ... -
Seeding as a start-up strategy for improving the acclimation of freshwater nitrifying bioreactors to salinity stress
Navada, Sharada; Gaumet, Frederic; Tveten, Ann-Kristin; Kolarevic, Jelena; Vadstein, Olav (Peer reviewed; Journal article, 2021)Recirculating aquaculture systems (RAS) for anadromous fish such as salmonids often require salinity changes during the production cycle. However, high or variable salinity can disrupt the biological nitrification process, ... -
