Abstract

Design and Construction of a Recirculating Aquaculture System without a constant water source

Nathan Huysman*, Eric Krebs and Michael E. Barnes

The use of Recirculating Aquaculture Systems (RAS) by governmental agencies to meet stocking needs is becoming commonplace. In South Dakota, the increasing need to grow cool and warm water species such as largemouth bass, bluegill, and channel catfish has necessitated the building of RAS. This paper describes the design, construction, and operation of a RAS built in a storage building at a cold water hatchery without a consistent water source. Each component of the RAS is described in detail and was designed to be cost effective while providing multiple years of service. During operation, the system successfully reared catfish, bluegill, and largemouth bass while maintaining acceptable water quality at 3-5% daily water exchange and minimal oxygen supply (during highest densities) at 2 L/ min of oxygen supply. The operational success of the system may encourage further development of RAS at state hatcheries.
