Smart System for Aquaculture

Fish farmers face many challenges: keeping the stock in a good condition and staying within small budgets for food and other resources. If you keep an eye on the water quality, you can lower the fish mortality in your stock and increase the feed conversion ratio. Our Water Quality Smart System helps you to do so.

decrease of fish mortality can be reached by good water quality

Many fish farmers know the problem of stock shrinkage. You have a higher number of fingerlings in the beginning than grown fish later. Very often, the reason for high mortality rates in aquacultures is poor water quality.

How to increase your stock output

Fish farmers need to deal with high costs for feed and infrastructure and a varying stock output. The mortality of fish in your stock can lower your turnover. What can you do to increase your feed conversion ratio and to reduce the fish mortality in your plant? The health of fish in aquaculture especially land-based farms can have several reasons: stress, lack of oxygen, too much feed, lack of fresh water, poor quality of recycling water, etc.

If you keep the environment of your stock in optimum conditions, you can reduce the risk of mortality by up to 40 %.

A continuous measurement of the water quality is essential and will help you to.

  • Check whether the water contains enough dissolved oxygen to keep your fish in a healthy state.
  • Control the level of ammonium for optimizing your feed conversion ratio and preventing fish toxins in recirculation water.
  • Monitor nitrate to avoid an excessive growth of algae.
  • Measure the pH level in order to assure high water quality.

Which Parameters Influence Fish Health?

monitoring of dissolved oxygen in water

Dissolved Oxygen

Every fish needs dissolved oxygen to survive. During the growth phase and during feeding, the fish consume enormous amounts of oxygen, which must be re-added to the water. Oxygen depletion leads to slower growth and, in the worst case, can mean the death of fish. By using aeration, you can hold the concentration of dissolved oxygen in your pond on an optimum level.

In order to hold the setpoint, you need to continuously measure the oxygen concentration and ideally the water temperature. A concentration of 8-10 mg/l of dissolved oxygen is generally recommended. Permanent oxygen measurement protects the fish against oxygen deficiency and reduces waste of money due to overdosing.

monitoring of ammonium in water


High concentration of ammonium (NH4+) has the effect that the fish cannot absorb energy from the feed any more. Even though increased ammonium concentration usually does not directly lead to death, there is always a risk, if the pH of the water rises. Ammonium then converts to ammonia (NH3), which is a very strong fish poison and deadly. A big disaster for your production.

The concentration of ammonium varies depending on the fish feeding and their excretions as well as the water treatment cleaning performance of the recirculation plant. This is why continuous ammonium measurement is so important for monitoring the quality of the fish tank water and controlling the water treatment plant.

monitoring of the nitrate level in water

Nitrate Level

Different concentrations of nitrate usually damage the health of the fish. But high nitrate concentration in the outlet of the fish plant have a negative impact on the environment. Nitrate promotes the growth of algae, which in turn can lead to increased oxygenation in deeper waters. Here anaerobic zones can develop that are very harmful to fish and other organisms in nature.

Observing the nitrate level is part of a fish farmer's main duties. Keeping the sensitive biotope in balance is a challenging task. Continuous measurement of nitrate can help to prevent a sudden growth of algae resulting in disturbances of oxygen levels.
