Oxygen and Oxygenation for Aquaculture

Taking oxygenation to a new level

Aquaculture, with its increasingly sophisticated onshore and offshore fish farming systems, is becoming widely recognized as a more sustainable option for meeting the rapidly rising global demand for seafood products. Linde oxygen and oxygenation systems help the aquaculture industry tackle a number of operational challenges to establishing a successful enterprise. Create healthier ponds and aquatic environments for maximum ROI. Our professionals secure delivery of pure oxygen for water systems to help reach your goals for production.

Benefits of Managed Dissolved Oxygen for Aquaculture

Supplementary oxygenation provides a healthier environment for growing fish which translates into increased productivity and improved financial performance for the farm. We specialize in integrating technology that outperforms traditional air-based systems. All of our options require little maintenance, and our equipment is known to lower electrical costs. Feed air from the environment into your water supply with little effort.

Maintaining the appropriate level of dissolved oxygen helps:

  • Achieve higher stocking densities

  • Increase the health and weight of fish

  • Boost water quality

  • Verify oxygen levels at various depths

  • Improve feed conversion ratio

  • Raise specific growth rate 

  • Reduce fish mortality

  • Lower the risk of disease in fish populations

  • Create a more humane environment for aquatic livestock

We are confident that Linde oxygen systems optimized for aquaculture help contribute to profitability. Our experts provide economical systems that are tailored for your industry, connecting you with fish farming equipment engineered to last.

Causes of Low Dissolved Oxygen

Dissolved oxygen plays a significant role in the quality of water. Most of the time, oxygenation for aquaculture and fish farming are necessary when there is excessive algae growth, as these plants consume oxygen when they undergo active photosynthesis. Similarly, when algae dies, the decomposition process uses a great deal of oxygen in the water. These factors can lead to poor yields and deteriorating wellbeing.

There is an ongoing need for oxygenation in aquaculture to eliminate stress on fish. It is hard to predict seasonal weather patterns, so dissolved oxygen levels help maintain a consistent environment. Aquatic species have an easier time surviving in waters where dissolved oxygen is abundantly available.

Our Oxygenation Systems for Aquaculture

There are multiple Linde oxygenation tools for the fish farming industry. Our versatile oxygen systems work in both salt water and fresh water sources. We understand the demands of your job, so we provide you with resources suitable for several types of fish farming, including salmonid, tilapia, catfish, and carp.

Buy Linde gases for aquaculture applications 


Linde is a leader in oxygenation technology for aquaculture. Linde's expansive line of SOLVOX® oxygenation products including the SOLVOX membrane oxygenator in-line product system are all designed for high energy efficiency, good oxygen utilization, operational reliability and optimum hydrodynamic conditions inside the tank. Dissolved oxygen concentrations are constantly affected by diffusion and aeration, photosynthesis, respiration and decomposition.


Carbon dioxide is injected into ponds and raceways to enhance the growth rate of microalgae used as a feedstock for the production of valuable nutrients and chemicals. This application of CO2 has also been proposed as a method to recycle carbon emissions by incorporating CO2 into the production of aquatic biomass. In addition, the dissolution of carbon dioxide helps to neutralize pH following photosynthesis cycles.
