The most important factor in achieving favourable results in fish farming is the oxygen level in the water. Fish absorb oxygen through direct contact with water.
Oxygenation of the water is a safety measure that protects the fish farmer against oxygen deficiencies occurring at a time when oxygen consumption by the fish or seafood is at its peak and when fish growth is at its best.
Nowadays the situation in intensive culture systems is to breed a high stocking density at low water consumption per kilogram of biomass. You cannot accomplish this without using oxygen. The oxygen content of the water is the single most important factor affecting how much your facility can produce.
Ensuring adequate oxygen levels in the water at all times is an important safety factor which affects growth, health, appetite and general well being of the fish. It also helps to reduce the effects of stress in fish that water temperature produces. It is of great importance how oxygen is implemented in fish farming operations. Properly applied, it will reduce risk factors and increase profitability, but improper usage can easily backfire.
Oxygen ultimately is not a substitute for water, too much oxygen can be harmful. In aquaculture operations, water has many functions that are just as important as supplying oxygen to the fish.
All this allows you to smoothly increase stock density, which gives an optimal feed conversion ratio and ensures the highest possible survival levels under optimum breeding conditions.
Linde supplies oxygen and the most efficient oxygenation equipment, continuously improved and developed in close interaction with our customers. But perhaps the most important knowledge we offer, is a thorough understanding of the interplay of cause and effect of all the elements in fish farming through our international network of fish farming experts. Our overall solutions for aquaculture simplify the combination of rational oxygenation and emergency supply from the same source.
Experienced and Knowledgable Partner
Linde has close contact with the industry and research institutes as well as our own international Aquaculture R&D centre placed in Norway.
Established in the buildings of a former salmon hatchery, it was rebuilt in 2003. The centre includes:
- Both freshwater and seawater facilities
- Water system based on recirculation
- Water heating system to easily control test-water temperature
- Aeration system that can reduce the oxygen saturation
- Laboratory
- Demonstration models
- Transparent waterpipes.
If you are active in aquaculture you can benefit from our experience. We are constantly engaged in developing new and better fish farming methods.
