Application and benefits of Bacillus licheniformis in aquaculture

Ⅰ、 Introduction to Bacillus licheniformis

Bacillus licheniformis is a beneficial bacterium commonly used in aquaculture. This type of bacteria is widely distributed in the natural environment and can decompose organic matter, inhibit bacteria, and improve aquaculture water quality. Meanwhile, Bacillus licheniformis can promote the growth and immunity of aquatic animals, making it the preferred choice for many aquaculture operators.

Ⅱ、 The role of Bacillus licheniformis

The role of Bacillus licheniformis in aquaculture mainly includes the following aspects:

1. Promote the growth of aquatic animals

Bacillus licheniformis can decompose organic and inorganic substances, releasing the organic nutrients needed for growth. At the same time, it can also release substances such as growth hormone and vitamins that promote the growth of aquatic animals, making their growth healthier and faster.

2. Improve immunity

Bacillus licheniformis can decompose harmful substances in waste and sewage, making water quality cleaner and reducing the growth of pathogenic bacteria in water. In addition, Bacillus licheniformis can stimulate the immune response of aquatic animals, improve their disease resistance, and reduce mortality caused by infection with pathogens.

3. Improve water quality

Bacillus licheniformis can decompose organic waste such as feed residues and metabolic products, promote the conversion of nutrients such as nitrogen and phosphorus in water, reduce the concentration of harmful substances in water, and improve water quality and environment.

4. Reduce breeding costs

Bacillus licheniformis can effectively enhance the growth rate and immunity of aquatic animals, while improving water quality and environment, thereby reducing breeding costs and increasing economic benefits.

Ⅲ、 Usage of Bacillus licheniformis

Bacillus licheniformis can be added as a microbial preparation to aquaculture ponds or as an additive to feed. The specific usage method is as follows:

1. Direct addition to the breeding pool: Add Bacillus licheniformis directly to the breeding pool, adding about 2000-3000 grams per acre of water and evenly dispersing it. Repeat adding every 7-10 days.

2. Additives: Add lichen spore powder to the feed in a ratio of 1-2% and stir evenly.

Ⅳ、 Precautions

When using Bacillus licheniformis, the following points should be noted:

1. Pay attention to the quality of bacteria

Choose high-quality and active lichen spore products to avoid the use of inactive or contaminated bacteria.

2. Pay attention to the usage amount

Excessive use of Bacillus licheniformis can cause damage to the microecological balance of water bodies, affecting aquaculture efficiency and water quality safety.

3. Pay attention to hygiene

The materials, equipment, etc. of the breeding pool and feed should be kept hygienic to avoid bacterial contamination.

【 Conclusion 】

Bacillus licheniformis is widely used as a biological agent in aquaculture, which has the functions of promoting growth, enhancing immunity, improving water quality, and reducing aquaculture costs. At the same time, it is easy to use and has high safety. However, attention should be paid to issues such as bacterial quality, usage, and hygiene during use.
