Review of Recirculation Aquaculture Systems Technologies

As a young industry growing rapidly in many countries around the world, technological innovation in aquaculture is commonplace. 

Recirculation Aquaculture Systems (RAS) have been in use in the northern hemisphere for many years in the freshwater rearing phase of Atlantic salmon farming during which time the scale, level of water reuse, complexity and the overall number of such installations have all increased.  In contrast, the development of RAS operations producing table ready fish in freshwater or sea water has been minimal with a number of developments proving to be financially unsustainable.  To our knowledge, commercially viable RAS production of Atlantic salmon for the table has yet to be clearly demonstrated.

In the midst of a phase of widespread profitability among salmon farming operators, renewed interest in RAS production of Atlantic salmon is clearly evident but there is a dearth of accessible independently collated information on the technologies employed in RAS and the prospects of their commercial viability.  HIE therefore commissioned an independent expert review of RAS technologies with particular focus on the commercial prospects for these systems and the implications for the HIE area of commercially viable RAS technologies.
