CARBON DIOXIDE CONTROL SYSTEM FOR AQUACULTURE

摘要

Some embodiments provide a recirculating aquaculture system for aquatic life. The system includes a culture tank, a sensor configured to measure a carbon dioxide concentration in the culture tank, a variable speed pump configured to circulate water through the culture tank, and a controller in communication with the sensor and the variable speed pump. The controller is configured to retrieve a maximum carbon dioxide concentration in the culture tank, retrieve a current carbon dioxide concentration, and compare the current carbon dioxide concentration to the maximum carbon dioxide concentration. When the current carbon dioxide concentration is greater than the maximum carbon dioxide concentration, the controller is configured to automatically increase the current water flow rate or automatically increase the current air flow rate based on the current gas to liquid ratio in the system.
