Monitoring CO2 for Aquaculture

Parameters: Carbon Dioxide

Lisa Goldie, a water quality researcher at Hubbs SeaWorld Research Institute, evaluated a 0-4,000ppm C-sense combined with a PME C-sense logger. The C-sense and logger were placed in a small tank with White-Striped Sea Bass and CO2 concentrations were measured every 10 minutes. A chemical was periodically added to the tank to control the CO2 concentration. The C-sense logger was critical for determining if this particular chemical was effectively removing the CO2 from the tank.

These data demonstrated that CO2 concentration in the water dropped after the chemical was added, but that CO2 levels once again increased within a short period of time, bringing the efficacy of the treatment into question. “The CO2 C-sense and logger were great, I loved them. This is a very valuable meter for my industry because low pH as a result of CO2being respired by the filters and fish is such a problem. I would recommend them to any intensive aquaculture facility in the world,” said Lisa Goldie with Hubbs SeaWorld Research Institute.
