Aquaculture Probiotics: Bacillus subtilis

In aquaculture, feed is the most expensive production cost. The quality and quantity of diets are primary factors influencing shrimp/fish growth, shrimp/fish health, disease prevention, contamination and expenses. Utilization of probiotic bacteria has emerged as the best solution with innumerable applications in the aquaculture feed industry. Bacillus species ,Bacillus subtilis are one of the most researched bacteria for fish/shrimp probiotic development due to:

·         Versatile utilization of Growth Nutrients

·         High Enzyme production

·         Antimicrobial secretion

·         Produces spores

·         Develops in  both aerobic and anaerobic conditions

Bacillus subtilis is Generally Recognized As Safe (GRAS) by the Food and Drug Administration (FDA).

Alternative nutrition, vegetable proteins, carbohydrates, lipids and Bacillus subtilis probiotic strains, must be considered in shrimp/fish aquaculture production systems; as an option to eliminate animal feed ingredients, improves digestion-assimilation, reduce water pollution and diseases, increasing yields and profits.
