Abstract

In the present investigation an attempt was made to evaluate the effects of Probiotics and using of different carbon sources for biofloc production on water quality, microbial population, production rates. The carbon sources selected in the present investigation are Sugarcane molasses, Rice flour, Wheat flour, for the production of bioflocs in the culture operation for Litopenaeus vannamei. The results obtained in the present study by using different carbon sources for the biofloc production with probiotics results in the better water quality due to a reduction in the levels of the various forms of nitrogenous wastes with in the system when this carbon sources are applied to the culture system. Due to the addition of carbon sources, to the culture system, Ammonia, Nitrate and Nitrite contents were found to be fluctuated and differences in the fluctuations of the nitrogenous wastes following the addition of these selected carbon sources related to the type of flour was explored. The results obtained in the present study clearly demonstrates that, the identification of best carbon source that could help mitigate the occurrence of high levels of nitrogenous wastes in BFT system for culture operation. All the carbon sources selected in the present study, were seems to be highly efficient in inducing highest and best growth potentials in L. vannamei.
