Bacillus is often used in aquaculture, there are many different types, including: subtilis, lichens, laterosporus, etc., of which the Bacillus subtilis is the most common.

Misunderstanding 1: Bacillus subtilis is not suitable for aquaculture because of its high oxygen consumption.

Truth: it is true that the growth and reproduction of bacillus subtilis require the consumption of dissolved oxygen, but what really consumes a lot of dissolved oxygen in the pond is excessive organic matter, etc. The bacillus just likes to reproduce and survive in the environment with sufficient oxygen.

Misunderstanding 2: Bacillus subtilis inhibit cyanobacteria and purify water, so Bacillus subtilis lead to lack of nutrients in water

Truth: Bacillus subtilis ability to purify water is to decompose large organic matter into small molecules and provide nutrients for algae. Bacillus laterosporus can inhibit cyanobacteria effectively and Bacillus licheniformis is better at suppressing potentially dangerous bacteria.

Misunderstanding 3: Fish and shrimp will be poisoned if swallowed Bacillus subtilis

Truth: Bacillus subtilis can secrete a variety of enzymes, such as protease, amylase, cellulase and so on, not only has no toxicity, but also can assist the digestion and absorption of animals to promote them growth. bacillus subtilis entry into the intestinal tract can also consume free oxygen in the intestinal tract, promote the growth of beneficial bacteria, but also secrete vitamin B to improve fish and shrimp immunity

Misunderstanding 4: Using Bacillus subtilis when the disease will increase the death of fish and shrimp

Truth: As long as sufficient dissolved oxygen is ensured, it will not increase the death rate of fish and shrimp even if used Bacillus subtilis when fish and shrimp are sick.  Spore can reduce ammonia nitrogen , purify water quality, and combined with phototrophic bacteria the effect of ammonia nitrogen reduction is better.  Its growth and reproduction process will secrete subtilisin, polymyxin, nystatin, short bacitracin and so on, all have good antibacterial effect. So Bacillus subtilis is a good probiotic.
