Probiotics: Water Quality, Growth and Immunity Performance in shrimp Aquaculture

Over the last few decades, the aquaculture industry has grown and developed as one of the major food production industries. Increased stocking density and cultivated area are two ways to increase aquaculture production. Stocking density increases result in a decrease in water quality and the spread of pathogens. As a chemical substance, antibiotics are not widely accepted by consumers as a means of reducing pathogenic agents in aquaculture. Nowadays, probiotics are crucial to maintaining the health of farmed aquatic animals and increasing production performance without negatively affecting consumers. Probiotics are being used in more studies to achieve environmentally friendly sustainable aquaculture goals. Probiotics have been shown to improve water quality, feed efficiency, growth performance, digestive enzyme activity, immunity, and resistance to pathogens in shrimp aquaculture. The presence of probiotics helps shrimp under stressful conditions, such as handling, grading, transportation, vaccination, and disease treatment. In the aquaculture industry, probiotics are mostly Bacillus, Lactobacillus, Micrococcus, Enterococcus, Lactococcus, Streptococcus, and Carnobacterium species. This study examines the use and importance of probiotics in shrimp aquaculture, as well as their effects on water quality, growth performance, and immunity.
