Description Closed-system aquaculture presents a new and expanding commercial opportunity. Recirculating aquaculture
systems (RAS) are tank-based systems in which fish can be grown at high density under controlled environmental
conditions. They are closed-loop facilities that retain and treat the water within the system. In a RAS, water
flows from a fish tank through a treatment process and is then returned to the tank, hence the term recirculating
aquaculture systems. RAS can be designed to be very environmentally sustainable, using 90-99 percent less
water than other aquaculture systems. RAS can reduce the discharge of waste, the need for antibiotics or
chemicals used to combat disease, and fish and parasite escapes. RAS have been under development for over
30 years, refining techniques and methods to increase production, profit and environmental sustainability.
There is a large cost involved in setting up and running a recirculation system and we need to consider a
number of factors in designing the system that will fit our needs.
