To meet the growing global demand for seafood, more and more fish need to be raised in fish farms. Aquaculture is an essential link in the agricultural chain, protecting the oceans from over-fishing and producing healthy food with extremely high feed conversion efficiency.
As fish absorb oxygen through direct contact with water, dissolved oxygen is the most important factor in achieving good results in fish farming.
The current trend in intensive farming systems is to aim for a high population density with low water consumption per kilogram of biomass. This cannot be achieved without oxygen. By enriching water with oxygen, fish and seafood farmers can protect their stock against oxygen suffocation during peak consumption and growth periods.
Adequate oxygen content in the water at all times not only ensures growth, but also promotes the health, appetite and general well-being of the fish. Oxygen also helps to reduce the effects of temperature-induced stress in fish.
Application Expertise
When used correctly, oxygenation reduces risk factors and increases profitability, but improper use can be counterproductive. Ultimately, oxygen is not a substitute for water – too much oxygen can be harmful. The proper oxygen dosing technology enables a smooth increase stocking density, thereby ensuring an optimal feed conversion ratio and the highest possible survival rates under optimum breeding conditions.
That is where we can help. We supply both oxygen and oxygenation equipment, which has been carefully and continuously optimised in close collaboration with our customers. But perhaps our most important asset is the vast aquaculture experience we have gained over the years. Our international network of fish-farming experts have a deep understanding of the cause and effect relationship across all aspects of fish farming. Our all-in solutions combine regular supply with emergency backup.
Pioneering R&D Centre
Working closely with customers and research institutes, we have developed several ground-breaking technologies, many of which are tested at our own international R&D centre for aquaculture in Norway.
With our laboratory and demonstration models, we continuously develop and improve products and processes at our R&D centre for both freshwater and saltwater plants, especially focusing on:
- Recirculation-based water systems
- Water heating systems for easy control of test-water temperature
- Aeration systems to reduce oxygen saturation
- Transparent water pipes for in-depth process insights
