Abstract
The adoption of Recirculating Aquaculture Systems (RAS) technology is occurring worldwide. This paper describes the creation of a unique RAS system used for rearing muskellunge Esox masquinongy . The recirculating aquaculture system described in this paper is comprised of five 2.44-meter diameter dual-drain tanks, a drum filter, ultraviolet sterilization unit, carbon dioxide degassing tower, 5-ton split unit heat pump, a pressurized bead filter (PBF), and a nano bubbler. A fixed speed 1.5 horsepower pump circulated water at a rate of 0.738m 3/min throughout the main pumping loop, and a fixed speed 0.75 horsepower pump circulated water in the side loop at rate of 0.51m3/min. While this design worked, issues, particularly with water flows during certain events, occurred. Solutions to alleviate these problems and improve rearing efficiencies are described.
