4th NordicRAS Workshop on Recirculating Aquaculture Systems 2017

30 September - 1 October 2015, Molde, Norway

(Field excursion 2 October) 

Organised by the Nordic Network on Recirculating Aquaculture Systems (NordicRAS), the Technical University of Denmark (DTU Aqua), and Nofima

This biennial workshop aims at bringing together engineers, scientists, farmers, managers, equipment and systems manufacturers, consultants and other professionals with an interest in emerging RAS related issues.

Recirculation technology and the principle of farming fish in closed systems has developed for decades, and systems have been optimized to a point where genuine commercialization has started with increasingly larger systems, e.g., for production of smolt are being constructed.

Consistent with this development focus is slowly shifting from addressing mechanical / engineering related topics towards more integrated and complex issues such as water quality (chemical as well as microbial), optimization of fish health and welfare in RAS, and end-of-pipe treatment. The prospective of constructing not only a farming system but a complete unit that can handle both intake -and especially discharge water and sludge is gaining more and more attention as system size and commercialization increases.

The workshop starts September 30 at 10:00 (registration from 09:00 to 10:00) and ends 1 October 2015 at 15:00

For those interested it is possible to attend a field trip on October 2nd,visiting state-of-the-art commercial and research RAS based facilities in the vicinity of Molde. Read more on the Excursion Subsite
