Improving process control in recirculating aquaculture systems can reduce start-up and maintenance costs and increase the effectiveness of operations. Efficient control of temperature in recirculating systems may increase energy savings, improve productivity, and enhance sustainability. This study focused on cost-effective design, installation, and determination of heat transfer efficiency in small recirculating tank systems. A series of low-cost in-situ coil heat exchangers were developed and used to maintain desired operational temperatures via computer process control for several independent recirculating aquaculture systems. However no fish were in the tanks during preliminary testing. Knowledge of the functional heat transfer capability of such systems is necessary for effective design. The computerized process control system was coupled with controlled low-cost in-situ chillers and glass insertion heaters to impose desired temperature regimes in independent tanks.
