Bacillus licheniformis in Aquaculture
Firstly, Bacillus licheniformis can regulate the gut microbiota balance of aquatic animals, inhibit the growth of pathogenic bacteria, and promote the growth of beneficial bacteria. Through biological oxygen abstraction, the concentration of oxygen in the intestine is reduced, promoting the growth of anaerobic bacteria such as bifidobacteria and lactobacilli, thereby improving feed utilization and enhancing the nutrient absorption capacity of aquatic animals, promoting growth.
Secondly, Bacillus licheniformis helps enhance the immune system of aquatic animals and prevent the occurrence of diseases. It can decompose residual feed and organic matter in water, reduce the content of toxic substances in water, and improve water quality. In addition, it can also decompose harmful substances such as ammonia nitrogen and hydrogen sulfide in water, promoting the stability of aquaculture environment.
Moreover, Bacillus licheniformis has the ability to inhibit the proliferation of harmful algae such as blue-green algae and maintain the ecological balance of water bodies. Spraying Bacillus licheniformis preparations on aquaculture water surfaces can effectively inhibit the growth of harmful algae and maintain clean water quality.
Bacillus licheniformis can be used through two methods: oral mixing and external water mixing. Oral administration can regulate the balance of gut microbiota, while external application can regulate water quality and inhibit harmful algal growth. The specific usage amount needs to be adjusted based on factors such as actual breeding conditions, water quality, and feed types.
Generally speaking, the amount of water used for splashing is about 100-200 grams per acre of water surface, used 2-3 times a week; The amount of feed added is about 50-100 grams per ton of feed. In addition, Bacillus licheniformis is suitable for various aquaculture methods, including freshwater aquaculture, marine aquaculture, etc.
