Inside the shrimp
Disease costs tropical shrimp farming up to 40% of production a year. Many bacterial diseases, including Vibrio infections such as AHPND, start by colonising the gut. Probiotics add beneficial bacteria. Prebiotics feed them. Together they restore a gut community that resists pathogens and turns more feed into growth.
Beneficial bacteria occupy attachment sites and nutrients on the gut wall, leaving less room for Vibrio.
Some Bacillus produce AHL-lactonase, which breaks down the signals Vibrio use to coordinate attack, reducing biofilm and mortality.
Oligosaccharides and β-glucans feed beneficial bacteria. Together with probiotics they form a synbiotic.
A balanced gut community supports immune response and digestive enzymes, so more feed converts to growth.
