Messi Biology stated that aquaculture is an important part of the agricultural industry, providing people with abundant aquatic products. With the development of science and technology, magnesium oxide is increasingly used in aquaculture, which is of great significance for improving aquaculture benefits and ensuring the quality of aquatic products. This article will elaborate on the role, application and precautions of magnesium oxide.
Regulating water quality
Magnesium oxide can produce magnesium hydroxide colloid in water, which has good adsorption properties and can effectively adsorb suspended matter, organic matter, etc. in water bodies, reducing the turbidity of water bodies. At the same time, magnesium oxide can also combine with heavy metal ions in water to form precipitates, thereby purifying water quality.
Promoting growth
Magnesium oxide is one of the essential elements of aquatic organisms and plays an important role in the growth and development of aquatic animals. The appropriate addition of magnesium oxide can improve the disease resistance of aquatic animals and enhance their adaptability to environmental changes, thereby improving aquaculture benefits.
Protecting gill tissue
Magnesium oxide can be used as a natural protective agent to protect the gill tissue of aquatic animals from harmful substances. Studies have found that adding an appropriate amount of magnesium oxide can reduce the mortality of aquatic animals such as fish, shrimp and crabs caused by harmful substances such as ammonia nitrogen and nitrite.
Improve the utilization rate of bait
Magnesium oxide can improve the utilization rate of bait by aquatic animals. Studies have found that adding a certain proportion of magnesium oxide to feed can increase the absorption rate of fish for nutrients such as protein and fat in feed by about 20%, thereby improving the utilization rate of bait and reducing feed costs.
Preventing diseases
In the breeding process of aquatic animals such as fish and shrimp, regularly adding an appropriate amount of magnesium oxide can effectively prevent the occurrence of some diseases, such as bacterial septicemia and viral hemorrhagic disease.
Improve the bottom quality
Applying an appropriate amount of magnesium oxide at the bottom of the breeding pond can improve the bottom quality environment, promote the growth and reproduction of beneficial microorganisms, improve the self-repair ability of the bottom quality, and reduce the occurrence of diseases.
Increase oxygen content
In high-density breeding ponds, due to the large amount of oxygen consumed by biological metabolism, it is easy to cause water hypoxia. Adding an appropriate amount of magnesium oxide can release oxygen in the water body, increase the dissolved oxygen content in the water body, and is beneficial to the survival and growth of aquatic animals.
Messi Biology reminds everyone that although magnesium oxide has many benefits for aquaculture, excessive use can also have adverse effects on aquatic organisms. Therefore, when using magnesium oxide, the dosage should be reasonably controlled according to the needs of different breeding objects. When magnesium oxide is mixed with other substances, attention should be paid to the ratio. Generally speaking, the amount of magnesium oxide used per acre of water surface should not exceed 50 kilograms. In addition, when magnesium oxide is mixed with certain drugs, disinfectants and other substances, chemical reactions may occur, affecting the efficacy or disinfection effect. Therefore, when using magnesium oxide, relevant operating procedures should be followed to ensure safety and effectiveness.
Summary
Magnesium oxide plays an important role in aquaculture, which can effectively improve breeding benefits and ensure the quality of aquatic products. During use, attention should be paid to reasonable use and ratio to ensure that magnesium oxide can achieve maximum benefits.
