White Feces Syndrome (WFS) is an emergent disease of penaeid shrimp (Penaeus monodon and Pvannamei) that is identified by the presence of floating white fecal strings on pond water in grow-out ponds. Although the clinical manifestations of WFS are well defined, the underling etiology remains obscure.  WFS in Pvannamei pre-infected with EHP and challenged with a unique isolate of Vibrio parahaemolyticus isolated from the gastrointestinal tract of a shrimp displaying WFS. There is limited information on specific immune mechanisms provided by the shrimp gut microbiota there are evidences of its interplay with the digestive activities that directly affect shrimp
growth and severity of diseases. New emerging diseases were found to target the shrimp hepatopancreas causing growth inhibition, size disparity, loss of appetite and chronic mortality.

We have used silver nanoparticles & IgY antibodies to control Vibriosis. At the same time Selenium nanoparticles to boost immune system of shrimp. This helps to control bacterial and associated other infectious agents and help to improve productivity. In addition, chelated minerals, vitamins and growth promotors helps to improve recovery from disease.

Components and mechanism of action

  • Synergistic mechanism to control vibriosis
  • Specific IgY antibodies for vibriosis
  • Nanoparticle to control pathogenic bacteria
  • Natural phytochemicals, polyphenols and other herbal active principle
  • Immunostimulants to fight infections and reduce mortality
  • Quorum sensing breakers to remove foul biofilm
  • Nano-emulsion to deliver active constituents
  • Attractants and appetite stimulators for high feed intake
  • Herbal binders for delivery of active constituents without loss in water


  • Effective control of White Gut Diseases, White Fecal Matter, White Muscle disease and Loose Shell syndrome
  • Multiple approaches for complete control of bacterial diseases of gut
