Some embodiments provide a recirculating aquaculture system for aquatic life. The system includes a culture tank, a sensor configured to measure a current dissolved oxygen level 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 dissolved oxygen threshold level and a maximum gas to liquid ratio in the culture tank, retrieve the current dissolved oxygen level, compare the current dissolved oxygen level with the dissolved oxygen threshold level, and automatically increase one of a current water flow rate and a current oxygen flow through the system when the current dissolved oxygen level is less than the dissolved oxygen threshold level.
A method for controlling dissolved oxygen in an aquaculture system, the aquaculture system including a culture tank that houses aquatic life, the method comprising:
