Recirculating Growout Systems
Recirculating tank systems are utilized for studies on growout of various marine finfish species, since these systems conserve space and water and permit a high degree of environmental control.Two systems are currently in operation:
Intermediate-Scale Growout
Twelve 2.7-m3 tank system used for growth studies with hatchery-reared juvenile marine finfish, including dietary protein, lipid, and energy: protein requirements for optimal growth and feed utilization efficiency.
Near-Commerical Scale Growout
Four 16.7-m3 tank system, currently being used to study production and economics of southern flounder, black sea bass and red porgy. This near-commercial scale system incorporates state-of-the-art filtration technologies developed and tested by NCSU aquaculture engineer, Dr. Thomas Losordo. The system was built by UNCW Research Associate Patrick Carroll.
