Abstract: Eleven microsatellite markers were used to sort out genetic diversity and population differentiation of
Monopterus species complex of Northeast India. Samples of morphologically identified
M. albus (50 nos.) and
M. cuchia (180 nos.) were collected from Manipur and Assam, were allocated into four populations based on the geographical proximity of the water bodies. Polymorphism Information Content (PIC) across the eleven microsatellite loci ranged from 0.588 to 0.852. The mean single locus estimate of Wright’s inbreeding indices F
IT and F
IS were 0.132 and 0.177 and mean single locus estimate of Wright’s fixation index F
ST was 0.052. The average numbers of observed alleles (NA) and effective alleles (NAe) across 11 microsatellite loci were 9.73 and 6.33 respectively, suggestive of moderate heterozygosity. The mean expected heterozygosity within and among individuals of
M. albus was 0.573 and 0.709 respectively while these values for
M. cuchia ranged between 0.695 to 0.748 and 0.692 to 0.769, approves moderate genetic diversity in
M. albus and
M. cuchia. Population structure analysis placed
M. albus and
M. cuchia in two distinct clusters.
