The present study was conducted to investigate the level of polymorphism and genetic diversity in natural population of Labeo rohita collected from selected zones of River Ganga using microsatellite DNA markers. 5 primers out of 10 produced amplicons and were selected for primary screening and further genetic analysis of the population. On the basis of the values of Average Nei’s Genetic Diversity, observed and expected heterozygosity, fixation index, Shannon’s information index obtained through microsatellite marker technique, the present study is the indicative of the fact that the stock of L. rohita of Haridwar region of River Ganga is more genetically diverse and genetically differentiated as compared to the stock of Kanpur region as these sites are distantly located and having negligible chance of exchange of gene pool with each other which is responsible for weak sub-structuring of stocks. Genetic variation observed between the two riverine sites may also be caused due to high level of anthropogenic activities in Kanpur region thereby causing blockage of fish movement as well destruction of breeding grounds thus hampering the proper mating within the population and also reducing effective population size.
