Abstract: Efficacy of marine yeasts Debaryomyces hansenii(S8) and Candida tropicalis(S186) as immunostimulants to Indian white prawn Fenneropenaeusindicuswas estimated in comparison with Saccharomyces cerevisiaeS36. Biomass of yeast strains was prepared using Malt Extract Agar and incorporated into a standard diet to prepare yeast diets of varying concentrations. F. indicuswere fed these diets for a period of 14days and then challenged orally with white spot syndrome virus (WSSV) and immune assays like total hemocyte count, phenol oxidase, NBT reduction, alkaline phosphatase and acid phosphatase were performed. Generally yeast diets provided better protection to F. indicusagainst WSSV compared to control. Marine yeast diet was found to support maximum immunostimulation evidenced by enhanced shrimp immunity. The study showed that marine yeasts D. hansenii(S8) and C. tropicalis(S186) are effective immunostimulants in F. indicusand they perform better than the baker’s yeast, S. cerevisiae.
