It’s been ten years since the first Smolt Production in the Future conference took place in Sunndalsøra, Norway. “Back then, we were talking about using recirculation for smolt production. Now we are discussing closed-containment aquaculture and post smolt production.” says scientist Jelena Kolarevic in Nofima, head of the conference. “Even though progress is fast, the…
Patrik Tang is a PhD student who is linking several projects in CtrlAQUA. His key topic is to identify how environmental factors influence the plasticity of physiological processes in post-smolt salmon, for example in osmoregulation, barrier and stress functions. “My aim is to identify environmental-physiological thresholds for these processes, and to understand how do compromises…
Master’s student at the Norwegian University of Science and Technology (NTNU), Kristin Søiland has done experiments at Nofima’s facilities at Sunndalsøra: “I’ve learned so much from doing research work and getting to see what goes on behind the scenes. There is a vast amount of work behind each test. In collaboration with my supervisor, I’m…
Written by Reidun Lilleholt Kraugerud for the annual report 2017 of CtrlAQUA. “We all know that research yields both positive and negative results. But it is the challenging measurement conditions and poor visibility in recirculation aquaculture systems that have really driven our product forward. We have updated several components on the basis of tests we…
Written by Reidun Lilleholt Kraugerud for the annual report 2017 of CtrlAQUA. “Once we have control over the biology, efficiency and costs will fall into place,” says Siri Vike, head of PHARMAQ Analytiq. PHARMAQ Analytiq is a supplier of analytical services to prevent health problems in fish and is partnering with CtrlAQUA to develop fish…
In its third year, scientists, farmers and technology suppliers at the CtrlAQUA Centre have researched and acquired new knowledge about farming in closed-containment aquaculture systems. Such knowledge will contribute to the Centre’s ambition to make closed systems off-the-shelf products. In this annual report you can also read interviews with two industry actors at the centre…

Researchers at CtrlAQUA are working on the basis of a hypothesis that an extended phase in recycling facilities on land will improve the fish’s growth and welfare in the sea. In addition, longer time in land facilities will result in a shorter…
PhD student Sharada Navada in CtrlAQUA shows her research, which is about technology in indoor aquaculture. She investigates how fast one can switch from freshwater to seawater in the facility, without affecting the water cleaning capacity of the biofilter. What is a biofilter? ‒ Like all organisms, fish eat and excrete ammonia into the water,…
Opinion article by Øyvind Fylling-Jensen, Nofima (Norway) and Steven Summerfelt, Conservation Fund (USA). The past five years have created a near perfect storm of circumstances that has encouraged industry improvements and interest in indoor closed-containment systems. This is based on increased demand for salmon, demand for more environmentally friendly production systems and practices, and increased…
Åsa Espmark is the new Centre Director of CtrlAQUA. She takes over from Bendik Fyhn Terjesen who has headed the Centre from its inception in 2015. CtrlAQUA is a centre for research-based innovation (SFI) whose main goal is to make closed systems for salmon up to one kilo available off the shelf by 2023. Espmark…
