Review on Recirculating Aquaculture Systems (RASs) for Fish Growth
Abstract: The safe and healthy production of high-quality aquatic products is dependent on the use of a wide variety of water treatment equipment in recirculating aquaculture systems (RASs), which are models of intensive aquaculture facilities. With the use of bigger systems and improved production management procedures, significant cost reductions have been realised in the production of food fish. The work involved in handling fish must be minimised, and efficient tank rotational …
