Vasco Mota is becoming one of Norway’s foremost RAS scientists; land-based, closed-containment aquaculture systems using recirculated water. After completing his PhD and spending four years actively researching this field, the Nofima scientist is absolutely certain that RAS technology will play a key role in the future growth of aquaculture.

Audience from all over the world are virtually welcome to the aquaculture town of Sunndalsøra and the webinar «Smolt production in the future» 21 October.

Scientists have determined that salmon post-smolts tolerate similar level of ozone in brackish water as they do in freshwater.

Research from Nofima confirms that there are a number of ways to farm salmon.

Ambitions are high, funding is available and the technology is well on the way when it comes to closed aquaculture facilities. This means that the road from research to implementation may be short. This is what tempted two international scientists to move to Sunndalsøra on the west coast of Norway, to be involved in developing the new generation of closed-containment salmon aquaculture facilities.

Nofima has developed in collaboration with European partners a fully automatic sensor to measure levels of nitrogen compounds in recirculated water.

Four Norwegian research institutions, two outside of Norway and several industry partners from technology and the aquaculture industry have now started operations at a centre for innovation in closed-containment systems. The centre, CtrlAQUA, has been given NOK 200 million and eight years to reach its own ambition to make closed-containment systems for salmon up to one kilogram off-the-shelf systems.

Nofima is one of 17 institutions chosen recently to become hosts for Centres for Research-based Innovation (SFI). The centre is to contribute to solving some of the main challenges facing the aquaculture industry, such as lice and mortality.

It may be possible that all farmed salmon can survive in the facilities used for postsmolt production in the future. The key is careful control of the salmon’s environment as it grows.

Recirculation of water provides extremely good control of the water environment, sensible utilisation of water sources and better protection against infection.
