Automated Water Quality Monitoring & Control Systems

Frequently Asked Questions: Aquaculture


  1. Can the Aquaculture systems be used for waste water applications?

    Yes. The Campbell Scientific monitoring and control system are used in many applications. The system can be programmed to monitor and control any application.

  2. We have fish ponds, and prawn ponds, and are having difficulty with the water quality. Can you tell me which system would be most economical?

    Absolutely. Because each farm is unique in their configuration, the system will be designed to meet your needs. Please let us know your needs, and we can provide a solution. We also have very capable system integrators that we can recommend to install a system for you.

  3. How do you control the oxygen level in water?

    Oxygen is controlled in water by forcing oxygen into the water. There are typically three ways to accomplish this. 

    1. Place a paddlewheel type device that mixes the water so that more water comes into contact with the air. This process is used in open pond systems. This can only increase the amount of dissolved oxygen in the water to be in equilibrium with the atmosphere.

    2. Force pressurized air (or pure oxygen) in the water with diffusers.

    3. Allow the water to free fall through the air. This process releases any over-saturated gases, as well as increases the surface area of the water, so that more dissolved oxygen in the area can be exposed to the water. Control the mechanical equipment that forces more oxygen into the water. In open ponds this is traditionally done by turning on paddle wheel aerators. In closed re-circulating tank systems, this is done by turning on additional aerator pumps.



  4. I have a RAS tilapia system in South Africa. I want to start with a small but expandable solution to monitor and log at least DO and temp.

    Campbell Scientific can provide an inexpensive system to measure the dissolved oxygen and temperature of the water. This data can then be used to monitor current conditions and log this data to control aeration or send alarms. Each system is unique to the needs of the farms. Understanding the farm layout is critical to provide the correct system.
