Farming salmon in the Swiss Alps

A new concept of recirculated aquaculture system (RAS), the RAS 2020, is already delivering the first batches of Atlantic salmon in Switzerland after successful trials with land-based farmed trout.

Smoltification occurs in separate RAS tanks, and the company imports eggs from Iceland, Thomas Hoffmann, from Swiss Alpine Fish, told IntraFish.

The innovative technology consists of a circular tank with two different rings: in the inner ring, salmon is grown up to one kilo, and in the outer ring salmon is grown from one to four kilos.
