Abstract
The efficacy of a marine yeast Candida sake as source of immunostimulant to Indian white shrimp Fenneropenaeus indicus was estimated. Biomass of C. sake was prepared using malt extract agar and incorporated at graded levels into a standard diet to prepare yeast diets of varying biomass concentrations (1%, 10% and 20%). F. indicus were fed on these diets for a period of 28 days and challenged orally with white spot syndrome virus (WSSV) and immune parameters such as total haemocyte count, phenoloxidase and nitroblue tetrazolium reduction (NBT) were determined. Ten per cent C. sake in the diet was found to support an optimum immune response in the animals in general and their enhancement could be observed on the second and third day following challenge with the virus. The study has demonstrated that marine yeast C. sake at 10% in diet (w/w) may be used as an effective source of immunostimulants in F. indicus.
