CtrlAQUA was a centre for research-based innovation (SFI) doing research on closed-containment aquaculture systems, and running from 2015 to 2023. The main goal was to develop technological and biological innovations that would make closed systems a reliable and economically viable technology.

Closed systems can be land-based where water is recycled, or sea-based, in which large floating tanks receive clean water from depth. In CtrlAQUA the research is dealing with both approaches.

The research focus is on the most sensitive phases for the salmon in the production cycle, such as the first seawater phase, the so-called post-smolt stage. However, this research is also very relevant for production all the way to harvest size in closed systems. The main innovation we are working towards in CtrlAQUA is to establish reliable and efficient production of post-smolts in closed systems on land or at sea. Thus, the industry can get a good and realistic alternative or supplement to the current production technology using open cages.

The centre will also contribute to better production control, fish welfare and sustainability in closed-containment farms. This will happen through development of new and reliable sensors, minimizing environmental impact through recycling of nutrients and reduce the risk of escape, and diseases transmission to wild stocks.

These innovations are of considerable value to the Norwegian society, since closed systems for strategic phases in salmon farming can help to make the vision of an eight-fold growth in value creation from aquaculture possible, and lead to increased number of jobs and production of healthy seafood.

There are challenges that may hinder growth of the salmon industry, such as sea lice, diseases, escapes, and the loss of fish through production.

Innovations in closed-containment aquaculture systems, where the salmon is separated from the outside environment by a tight barrier, can be important for further development of aquaculture.

“We are delighted that we have been granted funding for research in this field, with innovation as its goal. We have a broad network of scientists, suppliers and the aquaculture industry in this centre, and all are eager and expectant,”
