The main issues for Recirculating Aquaculture Systems (RAS) are analyzed, in order to lead to better
solutions for future managers, identifying possible areas for improvements and future challenges for the
industry. RAS-based production companies, researchers, system suppliers and consultants were interviewed
separately, in order to gain an overall understanding of those systems and what developments
could assist, in a positive way. Answers and subsequent analysis identified as significant barriers: poor
participation by the producers; a disincentive on sharing information; and a lack of communication
between different parties. The main issues are poor designs of the systems, as many had been modified
after a previous approach was unsuitable; and their poor management, due mainly to an absence of skilled
people taking responsibility for water quality and mechanical problems. As RAS will play an important
role within the future of aquaculture, their enhancement is needed. Key priorities are the necessity to
improve equipment performance, through researching at a commercial scale and further work on the
best combinations of devices for each particular situation. Additional recommendations are for a specialized
platform, to share knowledge on RAS, together with a more indepth and distinctive education
programme.
