Fish farming is one of the world’s fastest-growing industries, driven by the demand for quality seafood and sustainable practices. In this article, we’ll explore the role of Dissolved Oxygen (DO) in fish health, the consequences of low DO, and how PSA oxygen generators can be a game-changer for maintaining the right DO levels efficiently.
A crucial aspect of successful fish farming is maintaining optimal conditions in the pond environment, primarily through proper levels of:
- Dissolved Oxygen (DO)
- Temperature
- pH Levels

Importance of Dissolved Oxygen (DO) in Fish Farming
Dissolved Oxygen (DO) refers to the amount of oxygen present in water, which is vital for aquatic organisms.
Effects of Low DO Levels on Water Bodies
Insufficient DO levels can lead to several negative consequences for fish and other aquatic life. Here are some benefits of maintaining an optimal DO level:
- Better Health: A fish pond with optimum DO levels ensures that fish get ample oxygen, improving overall fish health and providing a healthier yield.
- Faster Growth: Maintaining the correct DO level ensures faster growth of fishes and aquatic organisms, allowing for a higher quantity of fish per unit area. This leads to increased productivity and profitability.
- Lower Mortality Rates: Ensuring proper DO levels significantly reduces fish mortality, thus ensuring a more reliable yield for fish farmers.
How to Measure DO Levels in Water Bodies
Maintaining a minimum DO level of 6 ppm (parts per million) in fish ponds is essential. Regular monitoring can be done using a Dissolved Oxygen Meter. To measure DO, simply insert the probe into the water, and the device will provide an accurate oxygen reading.

Causes of Reduced DO Levels
DO levels can fluctuate based on several factors, including:
- Temperature Variations
Warmer water holds less oxygen, which can cause DO levels to drop during the hottest parts of the day. - Photosynthesis by Aquatic Plants
DO levels often peak during the day due to photosynthesis and decline at night when plants consume oxygen. - Pollutants and Organic Waste
Human activity, such as organic waste disposal and water pollution, leads to oxygen consumption by microorganisms during waste decomposition, which reduces DO levels.
To sustain healthy DO levels, fish farmers need efficient oxygenation methods that go beyond traditional approaches.
Methods to Increase DO Levels in Fish Ponds
Traditionally oxygen is injected into the water by blowing air via an air blower in the pond also called aeration. As air contains 20.9% oxygen, this oxygen gets into the water and increases the DO level but this method takes a lot of time and uses a high amount of electricity. with the growing need for fish in the market, time and cost, both become very important in this business.
With advancements in technology, Read More here:- PSA (Pressure Swing Adsorption) oxygen generators have become an ideal alternative for fish farmers. These systems produce oxygen with a concentration of 93%, which is injected into the water via diffusers. As the oxygen content in the product gas produced by the PSA system is almost 4.5 times of air, the DO level increases faster and consumes less electricity. This process of injecting oxygen in water is called oxygenation and is done by supplying oxygen via pipes into the water body using diffusers to increase the efficiency of .injection
Using PSA oxygen generators brings the following advantages:
- Faster Oxygenation
Since PSA generators produce a concentrated oxygen stream, they can raise DO levels faster than traditional air blowers, reducing the time required for oxygenation. - Lower Electricity Consumption
Higher oxygen concentration translates to less energy used compared to traditional air blowers, helping fish farmers reduce operational costs. - Efficient Infusion Process
Oxygen from the PSA system is delivered through pipes and diffused into the water using diffusers. These diffusers distribute oxygen evenly, ensuring higher efficiency in the infusion process.
Infusion Process and Benefits of Diffusers
The oxygen generated by PSA systems is introduced into the water through diffusers, which enhance the oxygen distribution. Diffusers release oxygen in fine bubbles, increasing the surface area and enabling better absorption into the water. This process allows fish farms to reach the desired DO levels quickly and maintain them efficiently.
Advancements in Oxygenation Technology
Research and innovation have led to the development of new oxygenation technologies, such as nanobubble technology, which creates ultra-fine oxygen bubbles that remain suspended in the water for extended periods. These advancements drastically reduce the cost and time of increasing the DO level in water bodies.
Conclusion
We can conclude that oxygenation via PSA oxygen generators is of substantial benefit to growing fishery business which saves both time and cost, and most importantly in case, the quality as well as yield of fish from the same pond. We recommend that regular monitoring of DO level shall be done and optimum level of DO be maintained in the water body for every fishery business owner.
