The Nordic Network on Recirculating Aquaculture Systems (NordicRAS) was formally founded at a steering committee meeting in April 2011 at DTU Aqua, Hirtshals, Denmark, with country representatives from Denmark, Norway, Sweden, Finland and Iceland.
The network is open to researchers, industry, governmental organisations, consultancies, NGO's and others with an interest in activities related to recirculating aquaculture systems (RAS).
The major aims of the network are to co-ordinate and strengthen research and development of recirculating aquaculture systems (RAS) in Nordic countries.
The objectives of the network are to:
The Nordic Council of Ministers (NCM) financed the first two years of the network (2011-2012). Since then, a workshop focusing on RAS related research has been held every other year with partial support from NCM. Biennial workshops will continue to be held for as long as members show interest, and future funding opportunities allow.
So far six workshops have been held:
The next workshop takes place on October 8-9, 2025 at Aalborg Congress and Culture Centre (AKKC) in Aalborg, Denmark.
Facts
Recirculating aquaculture systems (RAS) are intensive fish and shellfish rearing systems that re-use the water after it has undergone various treatment processes such as mechanical and biological filtration.
As a consequence, the discharge of nutrients and organic matter from farms applying RAS technologies is considerably reduced compared to more traditional systems.
