Analysis of the application of oxygen enhancers in aquaculture

Classification of oxygen enhancers

1Murray-quick-acting oxygenator

The time of increasing oxygen is relatively short, generally less than 4 hours, when the supply of oxygen is urgent, it can quickly alleviate the problem of insufficient dissolved oxygen. Such as shrimp floating head, power outage and other abnormal conditions.

2Murray-long-acting oxygenator

The time of increasing oxygen is longer, which can be as long as 2-3 days. It is generally a product of increasing oxygen to change the bottom, which can prevent hypoxia. Extensive use can improve the substrate and adjust PH and hardness to a small extent.

3Murray-oxygenation auxiliaries

By reducing the surface tension of water, enhancing water permeability, improving water oxygen solubility to improve the use of dissolved oxygen in water, or by oxidizing organic matter and reducing chemical oxygen consumption to improve dissolved oxygen in water.

The effect of oxygenator

1Murray-provide sufficient dissolved oxygen

In summer, there are often muggy, thunderstorm and other bad weather, and oxygen deficiency is often suddenly dissolved in high-density intensive farming ponds, so it is appropriate to use oxygenator, because it does not release oxygen as quickly as other chemicals, but provides oxygen steadily and persistently, and the process of producing oxygen is a three-dimensional oxygenation from the bottom of the pond to the surface, especially suitable for benthic aquatic animals and high-density aquaculture.

2Murray-adjust the PH value

Practice has proved that the oxygenator is very effective in adjusting PH value and avoiding acidification of water. The calcium hydroxide produced after the decomposition of the oxygenator can stabilize the pH of the water, increase the content of calcium ions in the water, and effectively prevent the soft shells of crustaceans such as shrimps and crabs.

3Murray-reduce ammonia and nitrogen content in water

Ammonia and nitrogen are the main factors that prevent the growth of fish. Sowing oxygen enhancer in water can obviously reduce the content of ammonia and nitrogen in water.

4Murray-removal of harmful gases such as hydrogen sulfide and carbon dioxide

The oxygen enhancer settling to the bottom of the pond can oxidize the organic matter at the bottom of the pond, purify the sediment, reduce the oxygen consumption at the bottom, and reduce the production of harmful substances such as ammonia nitrogen, nitrous acid, hydrogen sulfide and so on.

5Murray-stop the reproduction of anaerobic organisms and kill disease-causing bacteria

Oxygen enhancers can be used as oxidants for disinfection, which can effectively kill anaerobic bacteria and pathogenic bacteria, and play a role in clarifying water. Flocculent calcium hydroxide can precipitate some particles in water to achieve water purification, to a certain extent, increase the photosynthesis of floating plants and increase dissolved oxygen.

Matters needing attention

1. Rapid oxygenator is used for emergency and rapid treatment, but can not be used in large quantities. If it is used in large quantities, it will lead to the death of shrimp.

2. It should not be mixed with acids, heavy metals, reducing substances, combustibles and so on.

3. Please use it up as soon as possible after opening, so as not to lose efficacy due to moisture.

4. Do not be exposed to the sun or rain during transportation.

5. Pay attention to self-protection during use, especially if hydrogen peroxide is not splashed into your eyes and mouth. If there is spatter, please rinse with plenty of water immediately and go to the hospital for medical treatment if necessary.
