All industries are feeling the effects of climate change – such as increasingly infrequent snow and reduced rainfall, or, by contrast, heavy rain that leads to flooding – and fish farming is no exception. These changing conditions mean that the six carp ponds at the Rödental fish farm in Upper Franconia were suffering from insufficient water, severe sludge formation and not enough oxygen – a vicious circle that is far from rare.

The farm's low point came in 2016, when the entire carp population died when the water quality was severely impaired. But it was set to be an issue of the past. In his search for an effective, fish-friendly and sustainable solution, the farm's owner reached out to Oase.

Clean water, healthy carp and long-term pond fertility.

The result after one year can only be described as a complete success: algae formation has significantly declined and the oxygen content of the water has been increased to the desired level. Thanks to SchlixX Plus, the pond sludge has been greatly reduced and has also solidified.

And, most importantly, fish mortality wasn’t just successfully stopped – the carp population grew. As soon as seasonal conditions permit and the water temperature is consistently at least 8°C (required for the water therapy), the farm plans to use the method in the other ponds.

The fish farmer is extremely happy with the cost-effectiveness of the solution too. Thanks to the significantly increased yield of fish, the cost of the Oase Professional preparations is far outweighed by the additional income. And our highest praise came in a letter of recommendation: he thanked us for our advice and encouraged us to reference his positive experience in conversation with other fish farmers.
