How do modern liquid analysis sensors support aquaculture? Conductivity control and oxygen measurement in fish farming

Did you know that controlling conductivity and oxygen levels in water is essential for raising healthy fish? What if you could automate measurements in aquaculture to minimize resource consumption and improve the quality of the final product?

Thanks to modern measurement systems, it is possible to precisely monitor water parameters in real time, which significantly facilitates the work of fish farmers. Intelligent sensors not only eliminate human error, but also allow for a quick response in the event of undesirable environmental changes. Find out how JUMO's advanced solutions have supported sustainable fish farming and ensured optimal conditions for growth at a German company.

Why are conductivity control and oxygen measurement important in container fish farming?

Fish farming in closed systems requires precise water parameter management because fish live in a confined space and the quality of their environment has a direct impact on their health, growth, and survival. Conductivity and dissolved oxygen content in water are two indicators that largely determine water quality and, ultimately, the quality of the live product.

Conductivity – the key to optimal salinity

In marine fish farming in containers, artificially prepared seawater is used, which must have the right salinity for the fish to function properly. The electrical conductivity of water is a direct indicator of the level of salt and other dissolved substances, which allows for:

• Precise salinity control – ensuring conditions that correspond to the natural environment of the fish.
• Protection of fish against osmotic stress – too high or too low salinity can lead to health problems.
• Stability of the aquatic environment – maintaining optimal farming conditions in a closed system.

Oxygen measurement – the foundation of healthy farming

In recirculation systems, fish live in a relatively small volume of water and their demand for dissolved oxygen is very high. Oxygen deficiency can lead to:

• Stress and growth retardation – fish in hypoxic conditions grow more slowly and are more susceptible to disease.
  
• Increased mortality risk – drastic drops in oxygen can cause mass fish deaths.
• Disruption of biological processes – microorganisms that filter water also need oxygen to function properly.

How do modern technologies support fish farming? The JUMO solution

Automation in aquaculture significantly facilitates water quality management by eliminating the need for continuous manual monitoring of parameters. Thanks to intelligent sensors, it is possible not only to continuously monitor dissolved oxygen and conductivity levels, but also to automatically adjust water conditions to optimal values. Advanced control systems allow data to be integrated in the cloud, giving farmers access to detailed reports and enabling them to respond immediately to any irregularities. As a result, resource consumption is reduced and farming becomes more efficient and sustainable.

In cooperation with SEAWATER Cubes, JUMO has supplied a comprehensive water parameter monitoring system that enables precise control of water quality in recirculation systems. The solutions implemented included JUMO digiLine sensors for measuring conductivity, temperature, and dissolved oxygen, as well as the modular JUMO AQUIS touch system, which enables multi-channel monitoring and automatic adjustment of measured values.

Thanks to the use of digital sensors, SEAWATER Cubes was able to reduce the time spent on manual measurements to a minimum, which translated into greater efficiency in breeding. In addition, thanks to integration with the JUMO digiLine system, all measurement data is transmitted in real time to a central control unit, allowing for a quick response to any changes in the water environment. Intelligent water parameter management has significantly reduced resource consumption, reducing the amount of water replaced to less than 1% per day.

Thanks to JUMO's modern technologies, fish farming in container systems has become more predictable, stable, and environmentally friendly. Users have gained full control over the farming process, being able to monitor key parameters at any time and provide fish with optimal conditions for growth.
