Whiteleg shrimp,

Litopenaeus vannamei

, is among high commercial value aquatic species being cultured recently worldwide. However, because of the rapid development, coupled with the unusual climate change, the shrimp farming has severely suffered significant economic losses due to viruses and vibriosis diseases

Use of antibiotics are banned due to the potential development of multi-antibiotic resistance of pathogenic bacteria and residue accumulation in tissues. Economically efficient alternatives are prebiotics

ACTIVE-MOS is a natural prebiotic derived from the outer cell wall of a select strain of the yeast

Saccharomyces cerevisiae.

These are specifically known as mannan oligosaccharides, have been scientifically proven to benefit gut health and the immune systems of shrimp. The action of ACTIVE-MOS is two fold: Immobilizing pathogens present in the gut, and activating the immune system
