The demand for farmed carp species has increased significantly over the last decade due to their high market value. In culture of omnivorous species such as Rohu, Labeo rohita (L. rohita), intestine, gonads, culture water, sediments and even commercial products can be a source of appropriate probiotic. Probiotics technique is a promising statergy for improving aquaculture performance and it is known to have many health benefits including the ability to modulate growth responses and immune system on positive side. Also encapsulating probiotics to live feed is an efficient method to deliver probiotics to aquatic animals. Probiotics can be applied as a single strain or a combination of strains. The comprehensive literature search highlights the significant positive role of probiotics in culture of L. rohita. It inferred that, use of probiotics enhanced growth performance, survival (SUR), protein efficiency ratio (PER), amylase activity (AMY), total serum protein (TP), hemocrit, specific and non specific immune parameters. Furthermore, dietary administration of probiotics also accelerated heat shock protein (MSP) and gene expression in L .rohita. These findings encourage the use of probiotics as a valuable tool in optimizing the production of L. rohita in culture system. Moreover, dosage and duration of probiotics and age of the host species are the significant factors in achieving desired result. This review article aims to present research findings on the use of probiotics in farming of L. rohita. Furthermore, this study attempts to fill the gaps in existing knowledge for the merit of further investigation and developments.
