Different Applications of Bacillus amyloliquefaciens in Aquaculture
Bacillus amyloliquefaciens is very common probiotic, which has been proven beneficial to the breeding industry that is often troubled with problems such as high feeding density, water quality management, and disease transmission. In recent years, the application in animal husbandry (especially aquaculture) has attracted widespread attention.
Biological Agents
Bacillus amyloliquefaciens can be made into biological agents for disease control in aquaculture. It has antibacterial properties and can effectively combat some harmful pathogens to aquatic animals and plants, such as bacteria, fungi, and viruses.
Water Quality Improvement
Bacillus amyloliquefaciens can degrade organic matter in water, including undigested feed and excrement. It can promote the recycling of beneficial elements such as nitrogen and phosphorus in water bodies, reduce the content of ammonia nitrogen and nitrite in water bodies, improve water quality, and reduce the accumulation of harmful substances in aquaculture environments.
Growth Promotion
Bacillus amyloliquefaciens has the ability to produce plant growth hormones, which can promote the growth of aquatic plants and improve the feed utilization and growth rate of aquaculture animals. It can also enhance the immunity of farmed animals and reduce the occurrence of diseases.
Feed Additives and Biological Feed Additives
Bacillus amyloliquefaciens can be used as a feed additive, added to feed to improve the digestion and absorption rate and antibacterial ability of feed, and increase the feed conversion rate of aquaculture animals.
It can also be used as a biological feed additive to increase the appetite of aquaculture animals and promote digestion and absorption, which is beneficial for improving the growth rate and yield of aquatic animals such as fish and shrimp.
Aquaculture Wastewater Treatment
Bacillus amyloliquefaciens can be used as a biological treatment agent to treat aquaculture wastewater, degrade organic matter in wastewater, and reduce water pollution caused by wastewater.
Ecological Balance Maintenance
The application of Bacillus amyloliquefaciens in aquaculture systems helps maintain ecological balance by regulating the microbial community structure in water bodies, inhibiting the growth of harmful microorganisms, reducing the occurrence of diseases in aquaculture environments, and maintaining the health of aquatic ecosystems.
The application of Bacillus amyloliquefaciens in aquaculture provides a feasible solution to the challenges faced by the industry. It can effectively prevent and treat diseases, improve digestion and absorption, improve the breeding environment, and enhance stress resistance, and has broad prospects for application in aquaculture. It should be noted that comprehensive consideration should be given to the actual situation during use, following scientific usage methods and guidelines to ensure the health of the aquaculture environment and the sustainable development of aquaculture. In addition, it is recommended to consult professional aquaculture technicians or experts in related fields before using Bacillus amyloliquefaciens to obtain advice and guidance for specific aquaculture scenarios.
