Meet three CtrlAQUA students

An important task for an SFI is to educate students. In 2021 the three PhD students John Davidson, Enrique Pino Martinez and Sharada Navada defended their degrees at the University of Bergen and NTNU. Three central pieces of the puzzle to make closed  containment aquaculture off the shelf product, have been placed. Common for the…

Two pieces of fish health advice

Written by: Reidun Lilleholt Kraugerud for the CtrlAQUA Annual Report 2021 The fact that there are few salmon lice in semi-closed fish farms is the main argument for these farms having a future, says Are Nylund, a professor in fish health at the University of Bergen. Nylund has been researching pathogenic organisms in closed fish farms…

Annual report 2021 for CtrlAQUA is ready

In the newly released annual report of CtrlAQUA for 2021, focus has been placed on to what extent CtrlAQUA results have made the closed-containment aquaculture systems more “off the shelf”. Besides containing a sum up of the year, scientific highlights and more, you can meet scientists and students in CtrlAQUA working on key questions: Do…

Time of year for sea transfer decides RAS strategy

Raising large salmon smolt in Recirculating Aquaculture Systems (RAS) is pioneering work. Therefore, fish farmers have requested research on how different production strategies for large smolt in RAS affect growth, survival rates, welfare and sexual maturity during the sea phase. Scientists Trine Ytrestøyl from Nofima and Tom Ole Nilsen from the University of Bergen are…

PhD in quality of sensors

March 16 2022, student Xiaoxue Zhang defended her PhD thesis titled “The development of antifouling materials with potential application on sensors”. Zhang has been doing her PhD at the Norwegian University of Science and Technology (NTNU) in the SENSOR project of CtrlAQUA. NTNU-professor Øyvind Mikkelsen was her supervisor. About the subject Unwanted biofilm is one…

A lot to save from targeted UV

UV light can kill 99.9 percent of bacteria and viruses found in the inlet water of aquaculture facilities. But how large should the doses be? Recent Nofima research in the CtrlAQUA Intake project “Strategies for water treatment in closed-containment aquaculture” shows that there is a lot of gain from adapting the dose to the pathogen…

Working for cutting energy use in a growing industry

Written by: Reidun Lilleholt Kraugerud for the CtrlAQUA Annual Report 2020 With the pace of new land based salmon facilities being build, one can get the impression that there are few challenges remaining with RAS technology. However, the increasing number and size of plants are incentives for solving sustainability challenges for the technology provider Krüger Kaldnes.…

Annual report 2020 for CtrlAQUA released

The CtrlAQUA annual report for 2020 is now released, presenting an update on the latest development in research and innovation within closed containment aquaculture. “What stands out in 2020, is that CtrlAQUA is in continuous progress with solid work with innovations. However, there are still some bottlenecks left before we can say that the systems…

Few lice, but major R&D efforts are still required regarding closed sea-based facilities

Written by: Reidun Lilleholt Kraugerud for the CtrlAQUA Annual Report 2020 Cermaq has now started the third round of salmon production in closed containment systems, without having to delouse. In the neighbouring net pen, which has a traditional net system, they have had to delouse several times. It is precisely the combination of a semi-closed containment…
